Creating and Modifying a Client System Options File

Authorized User

During installation, Tivoli Storage Manager provides a sample client system options file called dsm.sys.smp. Use this file to specify one or more servers to contact for services, and the communications options for each server. The file can also include authorization options, backup and archive processing options, and scheduling options.

If you are a Authorized User, copy the dsm.sys.smp file to dsm.sys in your installation directory and modify the required options according to your needs. Required options are those that provide information that client programs need in order to establish communication with a Tivoli Storage Manager server.

Note:
You must name the client system options file dsm.sys.

Creating and Modifying a Client User Options File

During the installation, Tivoli Storage Manager provides a sample client user options file called dsm.opt.smp. This file contains processing options that are categorized as follows:

If you are a root user, you can create a default client user options file for all users on your workstation. If you want to use different options than those specified in the default client user options file, you can create your own client user options file.

To create and modify a default client user options file or client user options file, follow these steps:

  1. Click Utilities and then click Setup Wizard.
  2. Select the Help me configure the TSM Backup Archive Client checkbox.
  3. Select the create a new options file checkbox.
  4. Follow the instructions on the screen.

You can also create and modify a default client user options file or client user options file by performing the following steps:

  1. Change to the directory containing the sample file. If necessary, contact the root user on your workstation to determine the location.
  2. Copy dsm.opt.smp to dsm.opt or to a new file name of your choice.
  3. From the Tivoli Storage Manager GUI, click Edit and then click Preferences and enter any options that you want to change. See "Client Options Reference" for options supported on your platform and detailed information about each option.

    The preferences editor updates the client configuration files, dsm.opt and dsm.sys, if any options have changed.

    The preferences editor uses the environment variables DSM_DIR to locate the client system options file (dsm.sys) and DSM_CONFIG to locate the client user options file (default name dsm.opt). The preferences editor queries the server for options on the server, but only updates the client options file. The preferences editor groups the options into the following categories:

You may use some options only with commands. For more information about these options, see "Using Options with Commands".


Communication Options

You use communication options to specify how your client node communicates with a Tivoli Storage Manager server.

For UNIX you can use one of the following communication protocols:

Use the commmethod option to specify the communication protocol. For more information, see Commmethod.

You can also use the lanfreecommmethod option to specify the communication protocol in a SAN environment. See Lanfreecommmethod for more information.

Ask your Tivoli Storage Manager administrator for assistance in setting your communication options.

TCP/IP Options

To use the TCP/IP communication protocol, you must include the tcpserveraddress option in your client system options file (dsm.sys). The other TCP/IP options have default values which you can modify only if you want to change the default value.

For UNIX: If you plan to back up an NFS system, see Nfstimeout.

Table 13. TCP/IP Options

Option Description Page
httpport Specifies a TCP/IP port address for the Tivoli Storage Manager Web client. Httpport
httpsport Specifies a TCP/IP port address for the HTTPS secure socket layer (SSL) interface to the Tivoli Storage Manager Web client. This option is for AIX, AIX 5L, and Windows clients only. Httpsport
lanfreetcpport Specifies the TCP/IP port number where the Tivoli Storage Manager storage agent is listening. Lanfreetcpport
tcpbuffsize Specifies the size, in kilobytes, of the Tivoli Storage Manager internal TCP/IP communication buffer. Tcpbuffsize
tcpnodelay Specifies that Tivoli Storage Manager immediately sends small transactions to the server.This option is for a AIX and AIX 5L clients only. Tcpnodelay
tcpport Specifies the TCP/IP port address for a Tivoli Storage Manager server. Tcpport
tcpserveraddress Specifies the TCP/IP address for a Tivoli Storage Manager server. Tcpserveraddress
tcpwindowsize Specifies the size, in kilobytes, of the TCP/IP sliding window for your client node. Tcpwindowsize
webports Enables the use of the Web client outside a firewall by specifying the TCP/IP port number used by the Client Acceptor daemon and the Web Client Agent service for communications with the Web GUI. Webports

Shared Memory Options

You must install TCP/IP on your workstation to use the shared memory communication method.

Table 14. Shared Memory Communication Options

Option Description Page
shmport Specifies the TCP/IP port address on which the server listens to establish a shared memory connection. Shmport
lanfreeshmport Specifies the Shared Memory port number where the Tivoli Storage Manager storage agent is listening. Use this option when lanfreecommmethod=SHAREdmem is specified for communication between the Tivoli Storage Manager client and storage agent for processing between the client and the SAN-attached storage device. Lanfreeshmport

Server and Node Options

Authorized User

Use the following options to specify the server to contact for backup-archive services, and the client node for which to request backup-archive services.

Server Options

Use the servername option in your client system options file (dsm.sys) to specify the start of a group of options (stanza) used to connect to a Tivoli Storage Manager server. Multiple stanzas can be set up in the dsm.sys file to connect to different servers. Each stanza begins with a servername option and must contain all options required to establish communication with a server. The stanza can also contain other options for backup-archive operations.

If your client system options file contains only one stanza -- Your client node contacts the server specified in that stanza for all services.

If your client system options file contains more than one stanza -- You can specify a default server with the defaultserver option. If you do not specify a default server, by default Tivoli Storage Manager contacts the server specified in the first stanza of your client system options file (dsm.sys).

Place the defaultserver option at the beginning of your client system options file before any server stanzas.

Figure 2 shows a sample client system options file (dsm.sys).

Use the servername option in your default client user options file (dsm.opt) or on the command line to specify a server to contact for backup-archive services. This overrides the default server specified in your client system options file (dsm.sys).

Note: You cannot override the migration server specified in the client system options file.

Node Options

The following node option is specified in the client system options file (dsm.sys):

For the client user options file: Use the virtualnodename option in your client user options file, or use it with a command if you want to request services for a client node other than the one on which you are working. For example, if you have a hardware failure on your workstation, you can restore backup versions of files to a different workstation.

Note:
You must supply the password for the client node that you specify. Any user who can supply the correct password becomes a virtual root user and can access all backup versions and archive copies of files that originated from the specified client node.

Setting Options in a File

This section describes how to set options in your client system options file (dsm.sys) or client user options filedsm.opt , and how to use options with commands.

To view or modify the options file, click Edit and then click Preferences from the GUI. The graphical options editor updates the client configuration options file if any options have changed.

You can edit the client options file with your favorite text editor.

To set an option in these files, enter the option name and one or more blank spaces, followed by the option value. For example:

   compression  yes
   nodename     client_a

Some options consist of only the option name, such as verbose and quiet. You can enter the entire option name or its abbreviation. For example, you can specify the verbose option as either of the following:

   verbose
   ve

Follow these additional rules when entering options in your client user options file (dsm.opt):

If you update the client user options file while a GUI or Web client session is active, you must restart the session to pick up the changes.


Using Options with Commands

You can override some of the options in your options file by entering them with appropriate backup-archive commands. You cannot override options by entering them with HSM commands.

Options are processed in the following order (precedence):

  1. Options defined on the server with server-enforced client options. The server overrides client values.
  2. Options entered locally on the command line.
  3. Options defined on the server for a schedule using the options parameters.
  4. Options entered locally in the options file.
  5. Options received from the server with client options not enforced by the server. The server does not override client values.
  6. Default option values.

Tivoli Storage Manager also includes a group of client command options that you can enter only on the command line with specific commands. For a complete list of command line options, a description, and where to go in this book for more information, see "Using Options with Commands".

To use an option with a command, enter a dash (-), the option name, an equal sign (=), and the option parameters. For example,

   dsmc incremental -domain=/home

For options that do not include parameters, enter a dash (-) and the option name. For example,

   dsmc incremental -quiet
Note:
Use a leading dash (-) or forward slash (/) to indicate that the following text is the name of an option. If an object name begins with one of these characters you must surround it in either single quotes (') or double quotes ("). Most operating system command line processors strip the quotes before submitting the command line arguments to the Tivoli Storage Manager client application. In such cases, using escape characters or doubling the quotes allows the client to receive the quoted object name. In loop mode, surround such objects in either single quotes (') or double quotes (").

You can enter the entire option name or its abbreviation. For information about how to read the syntax diagrams, see "Reading Syntax Diagrams".

Entering Options with a Command

Follow these general rules to enter options with a command:


Client Options Reference

The following sections contain detailed information about each of the Tivoli Storage Manager processing options. Information for each option includes:

Afsbackupmntpnt

Root User

The afsbackupmntpnt option specifies whether you want Tivoli Storage Manager to see an AFS mount point as a mount point or as a directory. If Tivoli Storage Manager sees it as a mount point, it backs up only the name of the mounted volume during a backup operation. It does not back up the subtree by starting from the mount point directory. For more information about this option, see The Afsbackupmntpnt Option in the Appendix.

Options File

Place this option in the client system options file (dsm.sys) or the client options file (dsm.opt). Use this option with dsmafs and dsmcafs.

Syntax

                    .-Yes-.
>>-AFSBackupmntpnt--+-----+------------------------------------><
                    '-No--'
 
 

Parameters

Yes
Specifies that Tivoli Storage Manager views all AFS mount points as mount points and backs up only the mount point information for any mount point it encounters during a backup operation. This is the default.

No
Specifies that Tivoli Storage Manager views all AFS mount points as directories and backs up the contents of files and subdirectories of any mount point it encounters during a backup operation.

Examples

Options file:
afsbackupmntpnt no

Archsymlinkasfile

The archsymlinkasfile option specifies whether Tivoli Storage Manager follows a symbolic link and archives the file or directory it points to, or archives the symbolic link only. Use this option with the archive command.

Use the followsymbolic option to restore to a symbolic link (that is a virtual mount point). The followsymbolic option is not related to the archsymlinkasfile option.

Note:
The server can also define this option.

Options File

Place this option in the client options file (dsm.opt).

Syntax

                     .-Yes-.
>>-ARCHSYMLinkasfile-+-----+-----------------------------------><
                     '-No--'
 
 

Parameters

Yes
Specifies that Tivoli Storage Manager follows a symbolic link and archives the associated file or directory. This is the default.

No
Specifies that Tivoli Storage Manager archives the symbolic link and not the associated file or directory.

Examples

Options file:
archsymlinkasfile no

Command line:
archsyml no

Automount

Authorized User

The automount option specifies all automounted file systems in the domain that you want to mount when Tivoli Storage Manager starts so they can be included in backup processing. Use this option with the domain option.

It is unnecessary to explicitly specify the file system in the domain statement if the keywords all-auto-nfs or all-auto-lofs are used. SeeDomain for more information about working with Automounted File Systems and the domain option.

Options File

Place this option in the client options file (dsm.opt).

Syntax

             .- --------------.
             V                |
>>-AUTOMount--- filespacename-+--------------------------------><
 
 

Parameters

filespacename
Specifies one or more automounted file systems in your domain that are mounted and processed when the client starts.

Examples

Options file:
automount fs1 fs2

Command line:
Does not apply.

Changingretries

Authorized User

The changingretries option specifies how many additional times you want the client to attempt to back up or archive a file that is in use. Use this option with the archive, incremental, and selective commands.

Use this option only when serialization, an attribute in a management class copy group, is shared static or shared dynamic.

With shared static serialization, if a file is open during an operation, the operation repeats the number of times that you specified. If the file is open during each attempt, the operation does not complete.

With shared dynamic serialization, if a file is open during an operation, the operation repeats the number of times that you specified. The backup or archive occurs during the last attempt whether the file is open or not.

Note:
The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

                   .---------------.
                   V               |
>>-CHAngingretries---numberretries-+---------------------------><
 
 

Parameters

numberretries
Specifies the number of times a backup or archive operation is attempted if the file is in use. The range of values is zero through 4; the default is 4.

Examples

Options file:
changingretries 3

Command line:
Does not apply.   

Commmethod

Authorized User

The commmethod option specifies the communication method you use to provide connectivity for client-server communication.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-COMMMethod-+- TCPip-----+-----------------------------------><
              '- SHAREdmem-'
 
 

Parameters

TCPip
The Transmission Control Protocol/Internet Protocol (TCP/IP) communication method.

SHAREdmem

When specifying this communications method on AIX, you must be log in as root or have the same user ID as the process running the server.

Examples

Options file:
commm tcp

Command line:

Does not apply.

Commrestartduration

Authorized User

The commrestartduration option specifies the maximum number of minutes you want the client to attempt to reconnect with a server after a communication error occurs.

Note:
If a communication failure occurs when a schedule is running, the scheduled operation fails if the client cannot reconnect with the server before the startup window for the schedule ends.

You can use the commrestartduration option and the commrestartinterval in busy or unstable network environments to decrease connection failures.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-COMMRESTARTDuration- minutes--------------------------------><
 
 

Parameters

minutes
The maximum number of minutes you want the client to attempt to reconnect with a server after a communication failure occurs. The range of values is zero through 9999; the default is 60.

Examples

Options file:
commrestartduration 90

Command line:
Does not apply.

Commrestartinterval

Authorized User

The commrestartinterval option specifies the number of seconds you want the client to wait between attempts to reconnect with a server after a communication error occurs.

Note:
Use this option only when commrestartduration is a value greater than zero.

You can use the commrestartduration option and the commrestartinterval in busy or unstable network environments to decrease connection failures.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-COMMRESTARTInterval- seconds--------------------------------><
 
 

Parameters

seconds
The number of seconds you want the client to wait between attempts to reconnect with a server after a communication failure occurs. The range of values is zero through 65535; the default is 15.

Examples

Options file:
commrestartinterval 30

Command line:
Does not apply.

Compressalways

The compressalways option specifies whether to continue compressing an object if it grows during compression, or resend the object uncompressed. Use this option with the compression option.

Use the compressalways option with the archive, incremental, and selective commands.

Note:
The server can also define this option.

Options File

Place this option in the client options file (dsm.opt).

Syntax

                  .-Yes-.
>>-COMPRESSAlways-+-----+--------------------------------------><
                  '-No--'
 
 

Parameters

Yes
File compression continues even if the file grows as a result of compression. This is the default.

No
Backup-archive client objects are resent uncompressed if they grow during compression. API behavior depends on the application. Application backups may fail.

Examples

Options file:
compressalways yes

Command line:
-compressa=no

This option is valid only on the initial command line.

Compression

Authorized User

The compression option compresses files before you send them to the server. Compressing your files reduces data storage for backup versions and archive copies of your files. It can, however, affect Tivoli Storage Manager throughput. A fast processor on a slow network connection benefits from compression, but a slow processor on a fast network connection does not.

If you specify compressalways=yes, compression continues even if the file size increases. To stop compression if the file size grows, and resend the file uncompressed, specify compressalways=No.

If you specify compression=yes, you can control compression processing in the following ways:

This option controls compression only if your administrator specifies that your client node can compress files before sending them to the server.

Use the compression option with the archive, incremental, and selective commands.

Note:
The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys) within a server stanza.

Syntax

               .-No--.
>>-COMPRESSIon-+-----+-----------------------------------------><
               '-Yes-'
 
 

Parameters

No
Files are not compressed before they are sent to the server. This is the default.

Yes
Files are compressed before they are sent to the server.

Examples

Options file:
compression yes

Command line:

Does not apply.

Dateformat

The dateformat option specifies the format you want to use to display dates.

The AIX, AIX 5L, Solaris, and HP-UX clients support locales other than English that describe every user interface that varies with location or language. Solaris and HP-UX clients only support English, Korean, Simplified Chinese, Traditional Chinese, and Japanese locale information. The default directories for system-supplied locales are as follows:

The backup-archive and administrative clients obtain format information from the locale definition in effect at the time you start the client. Consult the documentation on your local system for details about setting up your locale definition.

Notes:

  1. This dateformat option does not affect the Web client. The Web client uses the date format for the locale that the browser is running in. If the browser is not running in a locale that Tivoli Storage Manager supports, the Web client uses the date format for American English.

  2. When you change the date format and use the schedlogretention option to prune the schedule log, Tivoli Storage Manager removes all entries in the schedule log with a different date format when pruning the log. When you change the date format and use the errorlogretention option to prune the error log, Tivoli Storage Manager removes all entries in the error log with a different date when pruning the log. When changing the date format, copy the schedule log and error log if you want to preserve log entries that contain a different date format.

Options File

Place this option in the client options file (dsm.opt).

Syntax

>>-DATEformat- format_number-----------------------------------><
 
 

Parameters

format_number
Displays the date using one of the following formats. Select the number that corresponds to the date format you want to use:

0
Use the locale-specified date format. For AIX, AIX 5L, Tru64 UNIX, HP-UX, SGI, and Solaris: This is the default if the locale-specified date format consists of digits and separator characters.

1
MM/DD/YYYY (This is the default)

For AIX, AIX 5L, Tru64 UNIX, HP-UX, SGI, and Solaris: This is the default if the locale-specified date format consists of anything but digits and separator characters.

2
DD-MM-YYYY

3
YYYY-MM-DD

4
DD.MM.YYYY

5
YYYY.MM.DD

For AIX, AIX 5L, Tru64 UNIX, HP-UX, SGI, and Solaris: To set a particular date format, edit the source file for your locale and modify the d_fmt line to support your needs. Whatever date format you select applies both to output and to input; however, the input year can be either 2 or 4 digits.

"%m/%d/%y"
Displays the date in the form MM/DD/YY
"%d.%m.%Y"
Displays the date in the form DD.MM.YYYY

Examples

Options file:
dateformat 3

Command line:
-date=4

This option is valid on the initial command line and in interactive mode. If you use this option in interactive mode, it remains in effect for the entire interactive session or until you enter another dateformat option.

Defaultserver

Authorized User

The defaultserver option specifies the default server to which you want to back up or archive files from your local systems.

If you have the HSM client installed on your workstation, and you do not specify a migration server with the migrateserver option, use this option to specify the server to which you want to migrate files. See Tivoli Space Manager for Unix Using the Hierarchical Storage Management Clients for more information.

Options File

Place this option at the beginning of the client system options file (dsm.sys) before any server stanzas.

Syntax

>>-DEFAULTServer- servername-----------------------------------><
 
 

Parameters

servername
Specifies the name of the default server to which you back up or archive files. The server to which files are migrated from your local file systems can also be specified with this option. You can use this option if you do not specify a migration server with the migrateserver option.

Examples

Options file:
defaults server_a

Command line:
Does not apply.

Dfsbackupmntpnt

Root User

The dfsbackupmntpnt option specifies whether you want Tivoli Storage Manager to see a DFS mount point as a mount point or as a directory. If Tivoli Storage Manager sees it as a mount point, it backs up only the name of the mounted fileset during a backup operation. It does not back up the subtree by starting from the mount point directory.

For more information on using the dfsbackupmntpnt option, see "The Dfsbackupmntpnt Option" in the Appendix.

Options File

Place this option in the client system options file (dsm.sys) within a server stanza, or in the client options file (dsm.opt). Use this option with dsmdfs and dsmcdfs.

Syntax

                    .-Yes-.
>>-DFSBackupmntpnt--+-----+------------------------------------><
                    '-No--'
 
 

Parameters

Yes
Specifies that Tivoli Storage Manager views all DFS mount points as mount points and backs up only the the name of the mounted fileset for any mount point it encounters during a backup operation. This is the default.

No
Specifies that Tivoli Storage Manager views all DFS mount points as directories and backs up the contents of files and subdirectories of any mount point it encounters during a backup operation.

Examples

Options file:
dfsbackupmntpnt no

Dfsinclexcl

Root User

If you use a DFS include-exclude options file, the dfsinclexcl option specifies the path and file name. You can use a DFS include-exclude options file to exclude DFS files or directories from backup. You can use a DFS include-exclude options file to assign different management classes to specific files or groups of files.

A DFS include-exclude options file pointed to by the dfsinclexcl option is used only when DFS files are examined for backup. For more information about setting DFS processing options, see Setting Processing Options in the Appendix.

Attention: A separate DFS include-exclude options file is required because the prefix /... means the global root in DFS. In a DFS include-exclude options file, the /... prefix is interpreted as the global root of DFS, and the /... prefix is used to match zero or more directories.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-DFSInclexcl filespec----------------------------------------><
 
 

Parameters

filespec
The filespec parameter specifies the path and file name of your DFS include-exclude options file.

Examples

Options file:
dfsinclexcl /usr/lpp/adsm/bin/backup.excl.dfs

Dirmc

Authorized User

The dirmc option specifies the management class you want to use for directories. If you do not specify this option to associate a management class with directories, the client program uses the management class in the active policy set of your policy domain with the longest retention period. Select a management class for individual directories that retains directories at least as long as it retains the files associated with them.

If you specify a management class with this option, all directories specified in a backup operation are bound to that management class.

The dirmc option specifies the management class of directories you back up and does not effect archived directories. Archived directories are always bound to the default management class.

The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-DIRMc- mgmtclassname----------------------------------------><
 
 

Parameters

mgmtclassname
Specifies the name of the management class you want to associate with directories. The management class name that you specify is used for all directories that you back up. If you do not use this option, the management class with the longest retention period is associated with directories.

Examples

Options file:
dirm managdir

Command line
Does not apply.

Domain

The domain option specifies the file systems that you want to include for incremental backup in your client domain. The server can also define this option.

Use the domain option in your client system options file to define your default client domain. Tivoli Storage Manager uses your default client domain in the following situations to determine which file systems to process during an incremental backup:

If you do not use the domain option to specify file systems in your client options file, Tivoli Storage Manager uses the all-local parameter as the default.

Note:
You can include a virtual mount point in your client domain. For information about defining a virtual mount point, see Virtualmountpoint.

When you use the domain option with the incremental command, Tivoli Storage Manager adds file systems that you specify to the file system defined in your client options file. For example, if you enter the following in your client options file:

   domain /home /usr /datasave     

and the following on the command line:

   dsmc incremental -domain="/fs1 /fs2"   

Tivoli Storage Manager performs an incremental backup for your /home, /usr, /datasave, /fs1, and /fs2 file systems .

If you use both a file specification and the domain option with the incremental command, Tivoli Storage Manager ignores the domain option and processes only those file systems specified in the file specification. For example, if you enter:

   dsmc incremental /fs1 /fs2 -domain="/fs3 /fs4" 

.

Tivoli Storage Manager performs an incremental backup for the /fs1 and /fs2 file systems only.

Attention: If you are running GPFS for AIX in a multi-node cluster, and all nodes share a mounted GPFS file system, Tivoli Storage Manager processes this file system as a local file system. Tivoli Storage Manager backs up the file system on each node during an incremental backup. To avoid this, you can do one of the following:

Automounted File Systems

When performing a backup with domain=all-local, files handled by automounter and loopback file systems are not backed up.

When performing a file system backup with domain=all-local, any subdirectories that are mount points for an automounted file system (autofs) are excluded from backup when the automounter has mounted these mount points. Any files that exist on the server for the automounted subdirectory are expired.

When performing a backup with domain=all-lofs, all explicit loopback file systems (lofs) are backed up and all automounted file systems are excluded. For loopback file systems handled by automounter, use domain=all-auto-lofs.

Only those automounted file systems that are mounted when the client starts, can be backed up using the domain option or the GUI. You cannot back up unmounted file systems monitored by an automounter.

You can use the automount option with the domain option to specify one or more file systems to be mounted when the client starts. See Automount for more information.

An automounted file system that is mounted when starting the client can be explicitly backed up by specifying the automounted file system with the incremental command. For example:

   dsmc incremental autofs_name

Virtual mount points cannot be used with automounted file systems.

For HP-UX: The domain option is enhanced with the new keywords all-auto-lofs and all-auto-nfs to support automounted file systems. To use this enhancement, set the autofs parameter to 1 in the /etc/rc.config.d/nfsconf file. Changing this parameter requires a reboot. For further information please refer to the HP documentation on this issue.

The following UNIX platforms support automounter, LOFS, or LOFS through automounter, as indicated:

Platform automounter LOFS LOFS through automounter
AIX and AIX 5L yes yes yes
Solaris yes yes yes
HP-UX yes yes no
SGI yes no yes
Tru64 UNIX yes no no
NUMA-Q yes no no
OS/390 UNIX yes no no

Notes:

  1. The Linux clients are not enabled for automounter support.

  2. Linux does not support loopback file systems. Instead, a loop device is available to allow devices or files mounted as whole file systems. The Linux clients do not support Loop devices. File systems mounted via the loop device are handled as local file systems with the corresponding file system type.

Options File

Place this option in the client system options file (dsm.sys) or the client user options file (dsm.opt).

Syntax

           .- -----------------.
           V .-all-local-----. |
>>-DOMain----+---------------+-+-------------------------------><
             +-domain--------+

             +-all-auto-nfs--+
             '-all-auto-lofs-'
 
 

Parameters

all-local
Backs up all local file systems except LOFS file systems and LOFS through automounter. This is the default.

The /tmp directory is not included.

domain
Defines the file systems to include in your default client domain.

When you use domain with the incremental command, it processes these file systems in addition to those specified in your default client domain.

all-lofs
Backs up all loopback file systems, except those handled by automounter.

all-nfs
Backs up all network file systems, except those handled by automounter.

all-auto-nfs
Backs up all network file systems which are handled by automounter.

all-auto-lofs
Backs up all loopback file systems which are handled through automounter.

Examples

Options file:

domain /tst /datasave /joe  
"domain all-local" 
 

Command line:
-domain=""/fs1
/fs2"" 
-domain=/tmp  
 

Domain.image

The domain.image option specifies the mounted file systems and raw logical volumes that you want to include for an image backup in your client domain. Raw logical volumes must be named explicitly. Use this option in your client options file to define your default client image domain. This option is valid for AIX, AIX 5L, HP-UX, and Solaris only.

If you do not specify a file system with the backup image command, the file systems you specified with the domain.image option are backed up.

When you specify a file system with the backup image command, the domain.image option is ignored.

If you do not use the domain.image option to specify file systems in your client options file, and you do not specify a file system with the backup image command, a message is issued and no backup occurs.

Note:
The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

                 .- ----------.
                 V            |
>>-DOMAIN.Image----+--------+-+--------------------------------><
                   '-domain-'
 
 

Parameters

domain
Defines the file systems or raw logical volumes to include in your default client image domain.

Examples

Options file:
domain.image /fs1 /fs2

Command line:
Does not apply.

Domain.nas

The domain.nas option specifies the volumes to include in your NAS image backups. You can specify all-nas to include all the mounted file systems on the NAS file server, except those you exclude with the exclude.fs.nas option. When you use this option in your client system options file (dsm.sys), the domain.nas option defines your default domain for NAS image backups.

Tivoli Storage Manager uses your domain for NAS image backups when you run a backup nas command and you do not specify which volumes to process.

When you perform a NAS file system image backup using the backup nas command, Tivoli Storage Manager adds volumes that you specify on the command line to the volumes defined in your dsm.sys file. For example, if you enter the following in your dsm.sys file:

domain.nas nas1/vol/vol0 nas1/vol/vol1

and you enter the following on the command line

dsmc backup nas -nasnodename=nas1 /vol/vol2

Tivoli Storage Manager performs a backup for the following volumes on node nas1: vol/vol0, vol/vol1, and vol/vol2.

When performing a backup, if you use a file specification and specify domain.nas=all-nas in the dsm.sys file, all-nas takes precedence. Tivoli Storage Manager processes all mounted volumes on the NAS file server.

The domain.nas option is valid for AIX, AIX 5L, and Solaris clients only

Note:
The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

               .- -----------.
               V .-all-nas-. |
>>-DOMAIN.Nas----+---------+-+---------------------------------><
                 '-domain--'
 
 

Parameters

domain
Defines the volumes you want to process.

all-nas
Processes all mounted volumes on the NAS file server, except those you exclude with the exclude.fs.nas option. This is the default.

Examples

Options file:

domain.nas nas1/vol/vol0 nas1/vol/vol1
domain.nas all-nas

Command line:
Does not apply.

Editor

The editor option turns the command line interface (CLI) editor and retrieve capability on or off.

If the editor and command retrieve functions are not working on a specific workstation setting, we recommend that you turn off this function.

Options File

Place this option in the client system options file (dsm.sys) or the client options file (dsm.opt).

Syntax

          .-Yes-.
>>-Editor-+-----+----------------------------------------------><
          '-No--'
 
 

Parameters

Yes
Turns on the CLI editor and command retrieve capability. This is the default.

No
Turns off the CLI editor and command retrieve capability.
Note:
The editor is not supported on OS/390 UNIX System Services, so the editor option should be set to No.

Examples

Options file:
editor yes

Command line:
Does not apply.

Enablelanfree

Authorized User

The enablelanfree option specifies whether to enable an available LAN-Free path to a storage area network (SAN) attached storage device. A LAN-Free path allows backup, restore, archive, and retrieve processing between the Tivoli Storage Manager client and the SAN-attached storage device.

To support LAN-Free data movement you must install and configure the Tivoli Storage Manager Managed System for SAN feature on the client workstation. For more information, refer to the following publications:

To specify a communication protocol between the Tivoli Storage Manager client and Storage Agent, see Lanfreecommmethod for more information.

Note:
To restore backup sets in a SAN environment, see Restore Backupset for more information.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

                 .-No--.
>>-ENABLELanfree-+-----+---------------------------------------><
                 '-Yes-'
 
 

Parameters

Yes
Specifies that you want to enable an available LAN-Free path to a SAN-attached storage device.

No
Specifies that you do not want to enable a LAN-Free path to a SAN-attached storage device. This is the default.

Examples

Options file:
enablelanfree yes

Command line:
-enablelanfree=yes.

Encryptkey

The encryptkey option specifies whether to save the encryption key locally when performing a backup-archive operation or whether to prompt for the encryption key. The encryption key password is saved to the TSM.PWD file in encrypted format. If you save the encrypted key password, you are not prompted for it each time you perform a backup, archive, or restore. Place this option in your client system options file.

Note: The Web client saves the encryption key password in the TSM.PWD file. If there no key is saved, you are prompted for the initial encryption key password when you begin encryption processing.

Both Authorized Users and non-root users can encrypt or decrypt data during a backup or restore operation depending on the value you specify for the passwordaccess option.

              '-prompt-'
 
 

Parameters

save
Specifies that you want to save the encryption key password to a local file TSM.PWD file in encrypted format. When you specify save, Tivoli Storage Manager does not prompt for the password for each backup and restore operation. This is the default.

prompt
Specifies that you want to save the encryption key password to a local file. Tivoli Storage Manager prompts for the password for each backup and restore operation.

Examples

Options file:
encryptkey prompt

Command line:
-encryptkey=prompt

Errorlogname

Authorized User

The errorlogname option specifies the fully qualified path and file name of the file where you want to store information about errors that occur during processing. The value for this option overrides the DSM_LOG or DSM_DIR environment variables. The dsmwebcl.log and dsmsched.log files will be created in the same directory as dsmerror.log.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-ERRORLOGName- filespec--------------------------------------><
 
 

Parameters

filespec
The fully qualified path and file name where you want to store error log information. Ensure that all directories and subdirectories in the path exist and are accessible by client processing. Tivoli Storage Manager will not create directories for you.

The default is the path indicated by the DSM_LOG or DSM_DIR environment variable. If DSM_LOG or DSM_DIR are not specified, the dsmerror.log file will reside in the current working directory.

The dsmerror.log file cannot be a symbolic link.

Examples

Options file:

errorlogname /tmp/tsmerr.log

Command line:

Does not apply.

Errorlogretention

Authorized User

The errorlogretention option specifies how many days to maintain error log entries before pruning, and whether to save the pruned entries. The error log is pruned when the first error is written to the log after a Tivoli Storage Manager session is started. If the only session you run is the client scheduler, and you run it twenty-four hours a day, the error log might not be pruned according to your expectations. Stop the session and start it again to prune the error log when the next error is written.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

                      .-N----.  .-D-.
>>-ERRORLOGRetention--+------+--+---+--------------------------><
                      '-days-'  '-S-'
 
 

Parameters

N  or  days
Specifies how long to wait before pruning the error log.

N
Do not prune the error log. This permits the error log to grow indefinitely. This is the default.

days
The number of days to keep log file entries before pruning the log. The range of values is zero through 9999.

D  or  S
Specifies whether to save the pruned entries. Enter a space or comma to separate this parameter from the previous one.

D
Discard the error log entries when you prune the log. This is the default.

S
Save the error log entries when you prune the log.

The pruned entries are copied from the error log to the dsmerlog.pru file located in the same directory as the error log.

Examples

Options file:
errorlogretention 400 S

Command line:

Does not apply.

Exclude Options

Authorized User

The exclude options exclude objects from backup image, or archive services. For example, you might want to exclude all temporary files, any local caches of network files, all files that contain compiled object code that you can easily reproduce using other methods, or your operating system files.

You can exclude specific files from encryption processing during a backup.

Notes:

  1. With the exception of exclude.fs, when you exclude a file that was previously included, existing backup versions become inactive during the next incremental backup.

  2. The server can define exclude options with the inclexcl option.

Exclude any system files or images that could corrupt the operating system when recovered. You should also exclude the client directory containing the client files.

Use wildcard characters to exclude a broad range of files. See "Including and Excluding Groups of Files" for a list of wildcard characters that you can use. Then, if necessary, use the include option to make exceptions.

To exclude an entire directory called any/test , enter the following:

  exclude.dir /any/test     

To exclude subdirectories that begin with test under the any directory, enter the following:

  exclude.dir /any/test*     

Attention: See "Excluding System Files" for a list of files that you should always exclude.

Compression Processing

If you want to exclude specific files or groups of files from compression processing during a backup or archive operation, consider the following:

Processing NAS File Systems

Use the exclude.fs.nas option to exclude file systems from Network Attached Storage (NAS) image backup processing.

A NAS file system specification uses the following conventions:

For example, to exclude the /vol/vol1 file system of a NAS node called netappsj, specify the following exclude statement:

exclude.fs.nas netappsj/vol/vol1

To exclude /vol/vol1 from backup services on all NAS nodes, specify the following exclude statement:

exclude.fs.nas /vol/vol1

Options File

Place this option in an include-exclude options file or the client system options file (dsm.sys).

Syntax

   .- ---------------.
   V                 |
>>---options pattern-+-----------------------------------------><
 
 

exclude
Excludes files that match the pattern from backup services. When you back up files, any files you exclude with this option are not considered for backup.

If you have the Backup-Archive client and the HSM client installed on your workstation, use this option to exclude a file or group of files from both backup and space management services. Any files you exclude with this option are not considered for backup or migration.

exclude.archive
Excludes a file or a group of files that match the pattern from archive services only.

exclude.backup
Excludes a file or a group of files that match the pattern from backup services only.

exclude.compression
Excludes files from compression processing if compression=yes is specified.

exclude.dir
Excludes a directory, its files, and all its subdirectories and their files from backup services. The exclude.dir option works only if the excluded directory is a subdirectory. Use this option to exclude a portion of your data in which no underlying files need to be backed up.

When you exclude a directory, you can still back up specific files within that directory using a selective backup. However, the next time you perform an incremental backup, these backup versions are expired. If you exclude a directory that was previously included, Tivoli Storage Manager marks existing backup versions inactive during next incremental.

exclude.encrypt
Excludes the specified files from encryption processing.

exclude.file
Excludes files, but not directories, that match the pattern.

exclude.file.backup
Excludes files that match the pattern from normal backup services.

exclude.fs
Excludes file spaces matching the pattern. The client does not consider the specified file space for processing and the usual deleted-file expiration process cannot occur. If you exclude a file space that was previously included, existing backup versions remain on the server subject to retention rules specified in the associated management class definition. This option is valid for UNIX clients only.

exclude.fs.nas
Excludes file systems on the NAS file server from an image backup when used with the backup nas command. If you do not specify a NAS node name, the file system identified applies to all NAS file servers. The backup nas command ignores all other exclude statements including exclude.fs and exclude.dir statements. This option is for AIX, AIX 5L, and Solaris clients only.

exclude.image
Excludes mounted file systems and raw logical volumes that match the pattern from image processing. This option is valid for AIX, AIX 5L, HP-UX, and Solaris clients only.

Parameters

pattern
Specifies the file or group of files that you want to exclude from backup services. End the pattern with a file specification.
Note:
For NAS file systems: You must prefix the NAS node name to the file specification to specify the file server to which the exclude statement applies. If you do not specify a NAS node name, the file system identified refers to the NAS nodename specified in the client system options file (dsm.sys) or on the command line.

If the pattern begins with a single or double quote or contains any embedded blanks or equal signs, you must surround the value in either single (') or double (") quotation marks. The opening and closing quotation marks must be the same type of quotation marks.

For the exclude.image option, the pattern is the name of a mounted file system or raw logical volume. Because this option excludes the entire named object and the files it contains from processing, you must use wildcards. For example, to exclude the /etc file system from image backup, enter the following:

   exclude.image /etc/*/*

Please note, that this example does not conform with normal include-exclude wildcard processing for UNIX.

Examples

Options file:
exclude /unix/
exclude /.../core
exclude /home/jones/proj1/*
exclude.archive /.../core
exclude.backup /home/jones/proj1/devplan/
exclude.dir /home/jones/tmp
exclude.backup /users/home1/file1
exclude.image /usr/*/*
exclude.encrypt /users/home2/file1
exclude.compression /home/gordon/proj1/*
exclude.fs.nas	 netappsj/vol/vol0

Command line:
Does not apply.

Httpport

Authorized User

The httpport option specifies a TCP/IP port address for the Web client.

Tivoli Storage Manager Firewall Support

The webports option enables the use of the Web client outside a firewall by specifying the TCP/IP port number used by the Tivoli Storage Manager Client Acceptor daemon and Web Client Agent service for communications with the Web GUI.

The ports you specify with the webports option and the client option httpport must be opened in the firewall.

To enable the backup-archive client, Command Line Admin client, and the Scheduler (running in polling mode) to run outside a firewall, the port specified by the server option tcpport (default 1500) must be opened in the firewall.

Note:
Tivoli Storage Manager does not support the scheduler running in prompted mode outside a firewall.

See Tcpport and Webports for more information. See "Tivoli Storage Manager Firewall Support" for further considerations regarding Tivoli Storage Manager firewall support.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-HTTPport- port_address--------------------------------------><
 
 

Parameters

port_address
Specifies the TCP/IP port address that is used to communicate with the Web client. The range of values is 1000 through 32767; the default is 1581.

Inclexcl

Authorized User

The inclexcl option specifies the path and file name of an include-exclude options file.

Place the inclexcl option in the include-exclude list in your client system options file (dsm.sys).

Multiple inclexcl statements are permitted. However, you must specify this option for each include-exclude file.

Ensure that you soter your include-exclude options file in a directory to which all users have read access. Ensure that your include-exclude options file is stored in a directory such as /etc.

When processing occurs, the include-exclude statements within the include-exclude file are placed in the list position occupied by the inclexcl option and processed accordingly.

If you have the HSM client installed on your workstation, you can use an include-exclude options file to exclude files from backup and space management, from backup only or from space management only.

For more information about creating an include-exclude options file, see "Creating an Include-Exclude List".

Options File

Place this option in the client system options file (dsm.sys) within a server stanza.

Syntax

>>-INCLExcl- filespec------------------------------------------><
 
 

Parameters

filespec
Specifies the path and file name of one include-exclude options file.

Examples

Options file:
inclexcl /usr/dsm/backup.excl
inclexcl /etc/inclexcl.def

Command line:
Does not apply.

Include Options

Authorized User

The include options specify one of the following:

If you do not assign a specific management class to objects, Tivoli Storage Manager uses the default management class in the active policy set of your policy domain.

Notes:

  1. An include option cannot override an exclude.dir option.
  2. The server can also define these options with the inclexcl option.

Compression Processing

If you want to include specific files or groups of files for compression processing during a backup or archive operation, consider the following:

Processing NAS File Systems

Use the include.fs.nas option to bind a management class to Network Attached Storage (NAS) file systems for backup processing.

A NAS file system specification uses the following conventions:

For example, to assign a management class to the /vol/vol1 file system of a NAS node called netappsj, specify the following include statement:

include.fs.nas netappsj/vol/vol1 nasMgmtClass

See "Creating an Include-Exclude List" for more information.

Options File

Place this option in the include-exclude options file or the client system options file (dsm.sys).

Syntax

   .- -----------------------------------.
   V                                     |
>>---options pattern -+----------------+-+---------------------><
                      '- mgmtclassname-'
 
 

include
Includes files or assigns management classes for backup or archive processing.

include.archive
Includes files or assigns management classes for archive processing.

include.backup
Includes files or assigns management classes for backup processing.

include.compression
Includes files for compression processing if you specify compression=yes.

include.encrypt
Includes the specified files for encryption processing. By default, Tivoli Storage Manager does not perform encryption processing.

include.file
Includes a file for backup services, or assigns a management class to a file.

include.fs.nas
Assigns a management class when used with the backup nas command. If you do not specify a NAS node name, the file system identified applies to all NAS file servers. The backup nas command ignores all other include statements. This option is for AIX, AIX 5L, and Solaris clients only.

include.image
Includes a file space or logical volume, or assigns a management class when used with the backup image command. The backup image command ignores all other include options. This option is valid for AIX, AIX 5L, HP-UX, and Solaris only.

Parameters

pattern
Specifies the objects to include for backup services or to assign a specific management class. End this variable with a file specification.
Note:
For NAS file systems: You must prefix the NAS node name to the file specification to specify the file server to which the include statement applies. If you do not specify a NAS node name, the file system identified refers to the NAS node name specified in the client system options file (dsm.sys) or on the command line.

If the pattern begins with a single or double quote or contains any embedded blanks or equal signs, you must surround the value in either single (') or double (") quotation marks. The opening and closing quotation marks must be the same type of quotation marks.

For the include.image option, the pattern is the name of a mounted file system or raw logical volume. Because this option includes the entire named object and the files it contains from processing, you must use wildcards. For example, to include the /etc file system for image backup, enter the following:

   include.image /etc/*/*

Please note, that this example does not conform with normal include-exclude wildcard processing for UNIX.

mgmtclassname
Specifies the name of the management class to assign to the objects. If a management class is not specified, the default management class is used.

Examples

Options file:
include /home/proj/text/devel.*

Lanfreecommmethod

Authorized User

The lanfreecommmethod option specifies the communications protocol between the Tivoli Storage Manager client and Storage Agent. This enables processing between the client and the SAN-attached storage device.

Use the lanfreeshmport to specify the Shared Memory port number where the Storage Agent is listening. See Lanfreeshmport for more information

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-LANFREECommmethod- commmethod-------------------------------><
 
 

Parameters

commmethod
Specifies the supported protocol for your Tivoli Storage Manager client:

TCPip
The Transmission Control Protocol/Internet Protocol (TCP/IP) communication method.

Use the lanfreetcpport to specify the TCP/IP port number where the Storage Agent is listening. See Lanfreetcpport for more information. For AIX, AIX 5L, and Solaris root users, the Shared Memory communication method is the default and TCP/IP is optional. AIX, AIX 5L, and Solaris non-root users can only use the TCP/IP communication method.

SHAREdmem
Use the Shared Memory communication method when the client and server are running on the same system. Shared Memory provides better performance than the TCP/IP protocol. This is the default communication method for AIX, AIX 5L, and Solaris root users. When specifying this communications method on AIX, the backup-archive client user must be logged in as root or have the same user ID as the process running the Storage Agent. AIX, AIX 5L, and Solaris non-root users must use the default TCP/IP communication method and cannot use the Shared Memory communication method. See Commmethod for logon restrictions when using this communication method.

Examples

Options file:
lanfreec tcp

Command line:
-lanfreec=tcp

Lanfreeshmport

Authorized User

The lanfreeshmport option specifies the Shared Memory port number where the Tivoli Storage Manager Storage Agent is listening. This option is valid for AIX, AIX 5L, and Solaris clients only.

Mailprog

Authorized User

The mailprog option specifies the program and user ID to which you want to send a newly-generated password when the old password expires. Use this option only when you select generate with the passwordaccess option.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-MAILprog filespec userid------------------------------------><
 
 

Parameters

filespec
Specifies the path and file name of the program to which you want to send a newly-generated password. The program you specify must accept standard output.

userid
Specifies the user ID of the user to whom you want to send a newly-generated password. For OS/390 UNIX System Services, enter the user ID in uppercase letters.

Examples

Options file:
mailprog /usr/bin/xsend root (for AIX, AIX 5L)
mailprog /bin/mailx USER1 (for OS/390 UNIX System Services)
Note:
Run the enroll command before you use xsend.

Command line:
Does not apply.

Managedservices

Authorized User

The managedservices option specifies whether the Tivoli Storage Manager Client Acceptor daemon (CAD) manages the scheduler, the Web client, or both.

See "Configuring the CAD to Manage the Scheduler" for instructions to set up the CAD to manage the scheduler.

The CAD serves as an external timer for the scheduler. When the scheduler is started, it queries the server for the next scheduled event. The event is either executed immediately or the scheduler exits. The CAD restarts the scheduler when it is time to execute the scheduled event.

Notes:

  1. If you specify the schedmode=prompt option, the server prompts the CAD when it is time to run the schedule. The scheduler will connect and disconnect to the server when the CAD is first started.
  2. Specify passwordaccess=generate in your client system options, so that Tivoli Storage Manager generates your password automatically. See Passwordaccess for more information.

Using the managedservices option can provide the following benefits:

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-MANAGEDServices--+----------+-------------------------------><

   managedservices webclient

Task
Specify that the CAD manages the scheduler only.
   managedservices schedule

Task
Specify that the CAD manages both the Web client and the scheduler.
   managedservices schedule webclient
Note:
The order in which these values are specified is not important.

Command line:
Does not apply.

Maxcmdretries

Authorized User

The maxcmdretries option specifies the maximum number of times the client scheduler (on your workstation) attempts to process a scheduled command that fails. The command retry starts only if the client scheduler has not yet backed up a file, never connected to the server, or failed before backing up a file. Use this option only when the scheduler is running.

Your administrator can also set this option. If your administrator specifies a value for this option, that value overrides what you specify in the client options file after your client node successfully contacts the server.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-MAXCMDRetries- maxcmdretries--------------------------------><
 
 

Parameters

maxcmdretries
Specifies the number of times the client scheduler can attempt to process a scheduled command that fails. The range of values is zero through 9999; the default is 2.

Examples

Options file:
maxcmdr 4

Command line:

Does not apply.

Memoryefficientbackup

The memoryefficientbackup option specifies a memory conserving algorithm for processing incremental backups, that backs up one directory at a time, using less memory. Use this option with the incremental command when your workstation is memory constrained.

Note:
The server can also define this option.

Options File

Place this option in the client options file (dsm.opt).

Syntax

                         .-No--.
>>-MEMORYEFficientbackup-+-----+-------------------------------><
                         '-Yes-'
 
 

Parameters

No
Your client node uses the faster, more memory-intensive method when processing incremental backups. This is the default.

Yes
Your client node uses the method that requires less memory when processing incremental backups.

Examples

Options file:
memoryefficientbackup yes

Command line:
-memoryef=no

Nasnodename

The nasnodename option specifies the node name for the NAS file server when processing NAS file systems. The node name identifies the NAS file server to the Tivoli Storage Manager server. The server must register the NAS file server.

You can specify this option on the command line or in the client system options file (dsm.sys).

You can override the default value in the dsm.sys file by entering a different value on the command line. If you do not specify the nasnodename option in the dsm.sys file, you must specify this option on the command line when processing NAS file systems.

The nasnodename option is valid for AIX, AIX 5L, and Solaris clients only

Options File

This option can be specified on the command line or in the client system options file (dsm.sys).

Syntax

>>-NASNodename- nodename---------------------------------------><
 
 

Parameters

nodename
Specifies the node name for the NAS file server.

Examples

Options file:
nasnodename nas2

Command line:
-nasnodename=nas2

Nfstimeout

The nfstimeout option specifies the number of seconds the server waits for a status system call on an NFS file system before it times out.

You can use this option to mitigate the default behavior of status calls on NFS file systems. For example, if an NFS file system is stale, a status system call will be timed out by NFS (softmounted) or hang the process (hardmounted).

When the value of this option is changed to a value other than zero, a new (child) process is created to issue the status system call. The new process is timed out by the main (parent) process and the operation can continue.

Note:
The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys) within a server stanza or the client options file (dsm.opt).

Syntax

>>-NFSTIMEout number-------------------------------------------><
 
 

Parameters

number
Specifies the number of seconds the server waits for a status system call on an NFS file system before timing out. The default is 0 seconds.

Examples

Options file:
nfstimeout 10

Command line:
-nfstimeout=10

This option is valid only on the initial command line. It is not valid in interactive mode.

Nodename

Authorized User

The nodename option identifies your workstation to the server. You can use different node names to identify multiple operating systems on your workstation.

When you use the nodename option, Tivoli Storage Manager prompts for the password assigned to the node you specify, if a password is required.

If you want to restore or retrieve files from the server while you are working from a different workstation, use the virtualnodename option. See Virtualnodename for more information.

If you are working from a different workstation, you can use the nodename option only if you specify passwordaccess=prompt.

When connecting to a server, the client must identity itself to the server. This login identification is determined in the following manner:

Options File

Place this option in the client system options file (dsm.sys) within a server stanza.

Syntax

>>-NODename- nodename------------------------------------------><
 
 

Parameters

nodename
Specifies a 1 to 64 character node name for which you want to request Tivoli Storage Manager services. The default is the name of the workstation.

Examples

Options file:
nodename cougar

Command line:

Does not apply.

Numberformat

The numberformat option specifies the format you want to use to display numbers.

The AIX, AIX 5L, Solaris, and HP-UX clients support locales other than English that describe every user interface that varies with location or language. Solaris and HP-UX clients only support English, Simplified Chinese, and Japanese locale information. The default directories for system-supplied locales are as follows:

The backup-archive and administrative clients obtain format information from the locale definition in effect at the time the client is called. Consult the documentation on your local system for details about setting up your locale definition.

Note:
This numberformat option does not affect the Web client. The Web client uses the number format for the locale that the browser is running in. If the browser is not running in a supported locale, the Web client uses the number format for American English.

Options File

Place this option in the client options file (dsm.opt).

Syntax

>>-NUMberformat- number----------------------------------------><
 
 

Parameters

number
Displays numbers using any one of the following formats. Specify the number (1-6) that corresponds to the number format you want to use.

1
1,000.00 (This is the default)

2
1,000,00

3
1 000,00

4
1 000.00

5
1.000,00

6
1'000,00

For AIX, AIX 5L, Tru64 UNIX, HP-UX, SGI, and Solaris: To define number formats, modify the following lines in the source file of your locale. Whatever format you select applies both to output and to input.

decimal_point
The character that separates the whole number from its fractional part.
thousands_sep
The character that separates the hundreds from the thousands from the millions.
grouping
The number of digits in each group that is separated by the thousands_sep character.

Examples

Options file:
num 4

Command line:
-numberformat=4

This option is valid on the initial command line and in interactive mode.

Optfile

The optfile option specifies the client user options file you want to use when you start a Tivoli Storage Manager session.

Syntax

>>-OPTFILE- file_name------------------------------------------><

Examples

Options file:
Does not apply.

Command line:
   dsmc query session -optfile= myopts.opt 
 

This option is valid only on the initial command line. It is not valid in interactive mode.

Password

The password option specifies a Tivoli Storage Manager password. If you do not specify this option and your administrator has set authentication to On, you are prompted for a password when you start a Tivoli Storage Manager session.

Note:
If the server prompts for a password, the password does not display as you enter it. However, if you use the password option on the command line, your password will display as you enter it.

The password option is ignored when the passwordaccess option is set to generate.

Options File

Place this option in the client options file (dsm.opt).

Passwordaccess

Authorized User

The passwordaccess option specifies whether you want to generate your password automatically or set as a user prompt. Your administrator can require a password for your client node by enabling the authentication feature. Ask your administrator if a password is required for your client node.

If a password is required, you can choose to:

Use the passworddir option in your client system options file to specify the directory location in which to store the encrypted password file. The default directory location depends on how the client was installed.

When the passwordaccess option is set to generate and you specify the password option, the password option is ignored.

Set the passwordaccess option to generate in the following situations:

Options File

Place this option in the client system options file (dsm.sys) within a server stanza.

Syntax

                  .-prompt---.
>>-PASSWORDAccess-+----------+---------------------------------><
                  '-generate-'
 
 

Parameters

prompt
You are prompted for your workstation password each time a client connects to the server. This is the default.

To keep your client node password secure, enter commands without the password and wait for Tivoli Storage Manager to prompt you for the password.

Each user must know the Tivoli Storage Manager password for your client node. Any user who knows the password for your client node can gain access to all backups and archives that originate from your client node. For example:

generate
Encrypts and stores your password locally and generates a new password when the old password expires. An encrypted password is kept on your workstation when a session starts.

A password prompt displays when registering a workstation with a server using open registration or if your administrator changes your password manually.

You can use the mailprog option to specify the program and user ID where you want to send the new password each time the old password expires.

When logging in locally, users do not need to know the Tivoli Storage Manager password for the client node. However, by using the nodename option at a remote node, users can access files they own and files to which another user grants access. If you change the name of your client node (using the nodename option in the dsm.sys file, and the same node name is specified in the dsm.opt file, Tivoli Storage Manager prompts the users for the client node password. If a user enters the correct password, the user becomes a virtual root user. The same is true if a user specifies the same node name using the nodename option with a command.

Examples

Options file:
passwordaccess generate

Command line:
Does not apply.

Passworddir

Authorized User

The passworddir option forces the directory location in which to store an encrypted password file. The default directory location depends upon how the client was installed.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-PASSWORDDIR- directoryname----------------------------------><
 
 

Parameters

directoryname
Specifies the path in which to store the encrypted password file. The name of the password file is TSM.PWD. If any part of the specified path does not exist, Tivoli Storage Manager attempts to create it.

The default directory for AIX and AIX 5L is /etc/security/adsm and for other UNIX platforms it is /etc/adsm.

Examples

Options file:
passworddir /etc/security/tsm    

Command line:
Does not apply.

Postschedulecmd/Postnschedulecmd

Authorized User

The postschedulecmd option specifies a command that the client program processes after it runs a schedule. The client program waits for the command to complete before it continues with other processing.

If you do not want to wait, specify postnschedulecmd.

Note:
The postschedulecmd option (and the postnschedulecmd option) can be defined on the server.

Options File

Place these options in the client system options file (dsm.sys).

Syntax

>>-+-POSTSchedulecmd--+-- "cmdstring"--------------------------><
   '-POSTNschedulecmd-'
 
 

Parameters

"cmdstring"
Specifies the command to process. You can enter a command to be executed after a schedule with this option. Use only one postschedulecmd option.

Use a blank, or null, string for cmdstring if you want to prevent any commands from running that the administrator uses for postschedulecmd or preschedulecmd. If you specify a blank or null string on either option, it prevents the administrator from using a command on both options.

If your administrator uses a blank or null string on the postschedulecmd option, you cannot run a post-schedule command.

If the command string contains blanks, enclose it in double quotes. If you have double quotes within the command string, use single quotes to enclose them.

Examples

Options file:
postschedulecmd "restart database"

The command string is a valid command for restarting your database.

Command line:
Does not apply.

Preschedulecmd/Prenschedulecmd

Authorized User

The preschedulecmd option specifies a command that the client program processes before it runs a schedule. The client program waits for the command to complete before it starts the schedule.

If you do not want it to wait, specify prenschedulecmd.

Note:
The preschedulecmd option (and the prenschedulecmd option) can also be defined on the server.

Options File

Place these options in the client system options file (dsm.sys).

Syntax

>>-+-PRESchedulecmd--+-- "cmdstring"---------------------------><
   '-PRENSchedulecmd-'
 
 

Parameters

"cmdstring"
Specifies the command to process. Use only one preschedulecmd option. You can enter a command to be executed before a schedule using this option.

Use a blank or null string for cmdstring if you want to prevent any commands from running that the administrator uses for postschedulecmd and preschedulecmd. If you specify a blank or null string on either option, it prevents the administrator from using a command on both options.

If your administrator uses a blank or null string on the preschedulecmd option, you cannot run a pre-schedule command.

If the command string contains blanks, enclose it in double quotes. If you placed double quotes within the command string, use single quotes to enclose them.

Examples

Options file:
preschedulecmd "<insert your database product's quiesce command here> database"

The command string is a valid command for quiescing your database.

Command line:
Does not apply.

Queryschedperiod

Authorized User

The queryschedperiod option specifies the number of hours you want the client scheduler to wait between attempts to contact the server for scheduled work. This option applies only when you set the schedmode option to polling. This option is used only when the scheduler is running.

Your administrator can also set this option. If your administrator specifies a value for this option, that value overrides the value set in your client options file after your client node successfully contacts the server.

Note:
The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-QUERYSCHedperiod- hours-------------------------------------><
 
 

Parameters

hours
Specifies the number of hours the client scheduler waits between attempts to contact the server for scheduled work. The range of values is 1 through 9999; the default is 12.

Examples

Options file:
querysch 6

Command line:
-queryschedperiod=8

This option is valid only on the initial command line. It is not valid in interactive mode.

Quiet

The quiet option limits the number of messages that display on your screen during processing. For example, when you run the incremental, selective, or archive commands, information may appear about each file that is backed up. Use the quiet option if you do not want to display this information.

When you use the quiet option, error and processing information appears on your screen, and messages are written to log files. If you do not specify quiet, the default option, verbose is used.

Note:
The server can also define the quiet option and override the client setting.

Options File

Place this option in the client options file (dsm.opt).

Syntax

>>-QUIET-------------------------------------------------------><
 
 

Parameters

There are no parameters for this option.

Examples

Options file:
quiet

Command line:

Replace

The replace option specifies what you want the system to do when it restores files that already exist on your workstation. This option applies to the restore, retrieve, and restore backupset commands only.

Options File

Place this option in the client options file (dsm.opt).

Syntax

           .-Prompt-.
>>-REPlace-+--------+------------------------------------------><
           +-All----+
           +-Yes----+
           '-No-----'
 
 

Parameters

Prompt
You are prompted whether to overwrite a file that already exists on your workstation. If the existing file is read-only, you are prompted whether to overwrite it. This is the default.

All
All existing files are overwritten, including read-only files. If access to a file is denied, you are prompted to skip or overwrite the file. No action is taken on the file until there is a response to the prompt.

Yes
Any existing files are overwritten, except read-only files. If a file is read-only, you are prompted to overwrite the file or skip it. No action is taken on the file until there is a response to the prompt. If access to a file is denied, the file is skipped.

No
Existing files are not overwritten. No prompts will display.

Examples

Options file:
replace all

Command line:
-replace=no

Resourceutilization

Authorized User

The resourceutilization option regulates the level of resources the Tivoli Storage Manager server and client can use during processing.

When you request a backup or archive, the client can use more than one session to the server. The default is to use a maximum of two sessions; one to query the server and one to send file data. The client can use only one server session if you specify a resourceutilization setting of 1. The client is also restricted to a single session if a user who is not authorized invokes a UNIX client with passwordaccess=generate specified.

A client can use more than the default number of sessions when connecting to a server that is Version 3.7 or higher. For example, resourceutilization=10 permits up to eight sessions with the server. Multiple sessions may be used for querying the server and sending file data.

Multiple query sessions are used when multiple file specifications are used with a backup or archive command. For example, if you enter:

inc filespaceA filespaceB

and you specified resourceutilization=5, the client may start a second session to query files on file space B. Whether or not the second session starts depends on how long it takes to query the server about files backed up on file space A. The client may also try to read data from the file system and send it to the server on multiple sessions.

The following factors can affect the throughput of multiple sessions:

Potentially undesirable aspects of running multiple sessions include:

Note:
The server can also define this option.

Options File

Place this option in the client system options file (dsm.sys).

Pruned entries are copied to the dsmsched.pru file that is stored in the same directory as the schedule log.

Examples

Options file:
schedlogretention 30 S

Command line:
Does not apply. 

Schedmode

Authorized User

The schedmode option specifies whether you want to use the polling mode (your client node periodically queries the server for scheduled work), or the prompted mode (the server contacts your client node when it is time to start a scheduled operation). All communication methods can use the client polling mode, but only TCP/IP can use the server prompted mode.

Note:
This option applies only if you are using the TCP/IP communication method, and the scheduler command is running.

Your administrator can specify that the server support both modes or just one mode. If your administrator specifies that both modes are supported, you can select either schedule mode. If your administrator specifies only one mode, you must specify that mode in your client options file or scheduled work will not process.

If you specify the prompted mode, you must supply values for the tcpclientaddress and tcpclientport options on the schedule command. You can then be contacted at an address or port other than the one that made first contact with the server.

Notes:

  1. Tivoli Storage Manager does not support the scheduler running in prompted mode outside a firewall.

  2. The server can also be define this option.

Options File

Place this option in the client system options file (dsm.sys).

Place this option in your client options file (dsm.opt).

Syntax

          .-No--.
>>-SUbdir-+-----+----------------------------------------------><
          '-Yes-'
 
 

Parameters

No
Subdirectories are not processed. This is the default.

Yes
Subdirectories are processed. Because the client program searches all subdirectories of a directory that is being processed, processing can take longer to complete. Specify Yes only when necessary.
Note:
If you use the preservepath option in addition to subdir=yes, it can affect which subdirectories are processed. For more information, see Preservepath.

If a subdirectory is a mounted file system, it will not process even if you specfify subdir=yes.

The tcpserveraddress option specifies the TCP/IP address for a server. You can obtain this server address from your administrator.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-TCPServeraddress- server_address----------------------------><
 
 

Parameters

server_address
Specifies a 1 to 64 character TCP/IP address for a server. Specify a TCP/IP domain name or a dot address.

Examples

Options file:
tcps dsmchost.endicott.ibm.com

Command line:
Does not apply 

Tcpwindowsize

Authorized User

The tcpwindowsize option specifies the amount of data in kilobytes that is buffered when receiving data on a TCP/IP connection. To improve backup or archive performance, increase the tcpwindowsize on the server. To improve restore or retrieve performance, increase the tcpwindowsize on the client.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-TCPWindowsize- window_size----------------------------------><
 
 

Parameters

window_size
Specifies the size, in kilobytes, to use for your client node TCP/IP sliding window.

The range of values is 1 through 2048. For Solaris the maximum value is 1024. The default is 32.

Note:
Depending on the operating system communication settings, your system might not accept all values in the range of values.

Examples

Options file:
tcpwindowsize 1

Command line:
-tcpw=24

This option is valid only on the initial command line. It is not valid in interactive mode.

Timeformat

The timeformat option specifies the format in which you want to display system time.

The AIX, AIX 5L, Solaris, and HP-UX clients support locales other than English that describe every user interface that varies with location or language. Solaris and HP-UX clients only support English, Simplified Chinese, and Japanese locale information. The default directories for system-supplied locales are as follows:

The backup-archive and administrative clients obtain format information from the locale definition in effect at the time the client is called. Consult the documentation on your local system for details about setting up your locale definition.

Note:
This timeformat option does not affect the Web client. The Web client uses the time format for the locale that the browser is running in. If the browser is not running in a locale that Tivoli Storage Manager supports, the Web client uses the time format for American English.

Options File

Place this option in the client options file (dsm.opt).

Syntax

>>-TIMEformat- format_number-----------------------------------><
 
 

Parameters

format_number
Displays time in one of the formats listed below. Select the format number that corresponds to the format you want to use.

0
Use the locale-defined time format.

For AIX, AIX 5L, Tru64 UNIX, HP-UX, SGI, and Solaris: This is the default if the locale-specified format consists of digits, separator characters, and, if applicable, the AM or PM string.

1
23:00:00 (This is the default)

For AIX, AIX 5L, Tru64 UNIX, HP-UX, SGI, and Solaris: This is the default if the locale-specified format does not consist of digits, separator characters, and, if applicable, the AM or PM string.

2
23,00,00

3
23.00.00

4
12:00:00 A/P

For AIX, AIX 5L, Tru64 UNIX, HP-UX, SGI, and Solaris: To set a particular time format, edit the source file for your locale and modify the t_fmt line to support your needs. Whatever time format you select applies both to output and to input.

"%H:%M:%S"
Displays time in the form hh:mm:ss with hh ranging from 0 through 23.
"%H,%M,%S"
Displays time in the form hh,mm,ss with hh ranging from 0 through 23.
"%I,%M,0p"
Displays time in the form hh,mm,ssA/P with hh ranging from 1 through 12 and A/P is the local abbreviation for ante-meridian (AM in English) or post-meridian (PM in English).

Examples

Options file:
timeformat 4

Command line:
-time=3

Txnbytelimit

Authorized User

The txnbytelimit option specifies the number of kilobytes the client program buffers before it sends a transaction to the server.

Note:
This option can also be defined and adjusted by the server as required during self-tuning operations.
A transaction is the unit of work exchanged between the client and server. Because the client program can transfer more than one file or directory between the client and server before it commits the data to server storage, a transaction can contain more than one file or directory. This is called a transaction group.

This option permits you to control the amount of data sent between the client and server before the server commits the data and changes to the server database, thus changing the speed with which the client performs work. The amount of data sent applies when files are batched together during backup or when receiving files from the server during a restore procedure.

The server administrator can limit the number of files or directories contained within a transaction group using the txngroupmax option; the actual size of a transaction can be less than your limit. Once this number is reached, the client sends the files to the server even if the transaction byte limit is not reached.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-TXNBytelimit- number----------------------------------------><
 
 

Parameters

number
Specifies the number of kilobytes the client program can buffer together in a transaction before it sends data to the server. The range of values is 300 through 2097152 (2 GB); the default is 2048.

Examples

Options file:
txnb 2048

Command line:
-txnb=2048

This option is valid only on the initial command line. It is not valid in interactive mode.

Users

Authorized User

The users option authorizes specific users on your workstation to request services from a server. You can use this option more than once to specify a large number of user IDs. If you do not specify group names with the groups option, or user IDs with the users option, all users can request Tivoli Storage Manager services. If you use the groups option, the users option, or both, only users included in one of the specified groups, or included in the list of users, can request Tivoli Storage Manager services.

Define your root user name only with the users option to exclude all other users from accessing the server.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

   .- -------------------.
   |       .- ---------. |
   V       V           | |
>>---USERs--- username-+-+-------------------------------------><
 
 

Parameters

username
Names a user that you want to authorize to request Tivoli Storage Manager services.

Examples

Options file:
users  carol  larry  davecd  kathyba  michelle
users  amyb  tkaspar  kbsmith  egray  srjames

Command line:
Does not apply.

Verbose

The verbose option specifies that you want processing information to display on your screen. This is the default. When you run the incremental, selective, or archive commands, information displays about each file that is backed up. Use the quiet option if you do not want to display this information.

If the server specifies either the quiet or verbose option in the server client option set, the server settings override the client values, even if force is set to No on the server.

Note:
The server can also define this option.

Options File

Place this option in the client options file (dsm.opt).

Syntax

>>-VErbose-----------------------------------------------------><
 
 

Parameters

There are no parameters for this option.

Examples

Options file:
verbose

Command line:
-verbose

This option is valid on the initial command line and in interactive mode.

Virtualmountpoint

Authorized User

The virtualmountpoint option defines a virtual mount point for a file system if you want to consider files for backup that begin with a specific directory within that file system. Using the virtualmountpoint option to identify a directory within a file system provides a direct path to the files you want to back up, saving processing time. It is more efficient to define a virtual mount point within a file system than it is to define that file system using the domain option, and then to use the exclude option in your include-exclude options list to exclude the files that you do not want to back up.

Use the virtualmountpoint option to define virtual mount points for multiple file systems, for local and remote file systems, and to define more than one virtual mount point within the same file system. Virtual mount points cannot be used in a file system handled by automounter. Use the AFS/DFS backup clients to process virtual mount points for AFS/DFS file systems.

Note:
If the directory that you want to specify as a virtual mount point is a symbolic link, set the followsymbolic option to Yes. If that option is set to No (the default), you are not permitted to use a symbolic link as a virtual mount point.

After you define a virtual mount point, you can specify the path and directory name with the domain option in either the default client options file or on the incremental command to include it for incremental backup services. Users can also specify the path and directory name of the virtual mount point with the domain option in their own client options files and on the incremental command.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

   .- ---------------------------.
   V                             |
>>---VIRTUALMountpoint directory-+-----------------------------><
 
 

Parameters

directory
Specifies the path and directory name for the directory you want to use as the virtual mount point for a file system. You cannot use wildcard characters in either the path or directory names.

Define only one virtual mount point with each virtualmountpoint option that you include in your client system options file. Use the virtualmountpoint option as many times as necessary to define all of the virtual mount points that you want to use.

Examples

Options file:
virtualmountpoint /afs/xyzcorp.com/home/ellen/
virtualmountpoint /afs/xyzcorp.com/home/ellen/test/data/

Command line:
Does not apply.

Virtualnodename

The virtualnodename option specifies the node name of your workstation when you want to restore or retrieve files to a different workstation.

When you use the virtualnodename option in your client options file, or with a command:

When connecting to a server, the client must identity itself to the server. This login identification is determined in the following ways:

When the virtual node name is accepted by the server, a password is required (assuming authentication is on), even if the passwordaccess option is generate. Once a connection to the server is established, then access is permitted to any file backed up using this login ID.

Options File

Place this option in the client options file (dsm.opt).

Syntax

>>-VIRTUALNodename- nodename-----------------------------------><
 
 

Parameters

nodename
Specifies a 1- to 64-character name that identifies the node for which you want to request Tivoli Storage Manager services. There is no default.

Examples

Options file:
virtualnodename cougar

Command line:
-virtualn=banshee

This option is valid only on the initial command line. It is not valid in interactive mode.

Webports

The webports option enables the use of the Web client outside a firewall by specifying the TCP/IP port number used by the Tivoli Storage Manager Client Acceptor daemon and Web Client Agent service for communications with the Web GUI.

If you do not specify this option, values for both the Client Acceptor daemon and the Web Client Agent service are required.

If you do not specify this option, the default value, zero (0), is used for both ports. This causes TCP/IP to randomly assign a free port number for the Client Acceptor daemon and the Web Client Agent service.

The ports you specify with the webports and httpport options must be opened in the firewall.

To enable the backup-archive client, Command Line Admin client, and the Scheduler (running in polling mode) to run outside a firewall, the port specified by the server option tcpport (default 1500) must be opened in the firewall.

Note:
Tivoli Storage Manager does not support the scheduler running in prompted mode outside a firewall.

To enable the administrative Web interface to run outside a firewall the port specified by server option httpport (default is 1580) must be opened in the firewall.

See Httpport and Tcpport for more information.

See "Tivoli Storage Manager Firewall Support" for further considerations regarding Tivoli Storage Manager firewall support.

Options File

Place this option in the client system options file (dsm.sys).

Syntax

>>-WEBPorts- cadportagentport--------------------------------><
 
 

Parameters

cadport
Specifies the required Tivoli Storage Manager Client Acceptor daemon port number. If a value is not specified, the default, zero (0), causes TCP/IP to randomly assign a free port number.

agentport
Specifies the required Tivoli Storage Manager Web client agent service port number. If a value is not specified, the default, zero (0), causes TCP/IP to randomly assign a free port number.

Examples

Options file:
webports 2123 2124

Command line:
Does not apply
