Administrator's Reference
Use this command to define a drive that TSM can use to access data on
storage volumes. Each drive is assigned to a single library. You
must define this library before you issue this command. You can define
more than one drive for a given library by issuing the DEFINE DRIVE command
once for each drive. Stand-alone drives always require a manual-type
library. For additional information, see Administrator's
Guide.
Privilege Class
To issue this command, you must have system privilege or unrestricted
storage privilege.

Notes:
- The ELEMENT parameter is required for drives in SCSI libraries.
- ACSDRVID is required for drives in ACSLS libraries. This parameter
is not valid for non-ACSLS libraries.
Parameters
- lib_name (Required)
- Specifies the name of the library to which the drive is assigned.
This parameter is required for all drives, including stand-alone
drives. The specified library must have been previously defined by
using the DEFINE LIBRARY command.
- drive_name (Required)
- Specifies the name that is assigned to the drive. The maximum
length of this name is 30 characters.
- DEVIce (Required)
- Specifies the name of the device that corresponds to the drive. For
example, you might specify mt5.0.0.1.
For a drive that is device type REMOVABLEFILE, specify its drive letter and
a colon, for example, E:.
This parameter is required for SCSI and 349X library types, but is not
valid for MANUAL, EXTERNAL, or ACSLS libraries. If the library type is
SCSI, only one device name is allowed. If the library type is 349X, you can specify 1 to 8 device names by
separating the names with commas and no intervening spaces.
For devices that are supported by either the ADSMSCSI driver or Windows NT
drivers, use an alias name to refer to the devices when using TSM. The
alias name replaces the real ADSMSCSI name or Windows NT name for a device in
TSM commands and screens.
An alias name has the form mtx.y.z.n or
lbx.y.z.n. The mt indicates
that the device is a tape device, and the lb indicates that the
device is the controller for a tape autochanger or an automated
library. The alias can be abbreviated. Some examples
follow:
- mt3
- Tape drive at SCSI ID 3, LUN 0 on bus 0, port 0
- lb4.1
- Library at SCSI ID 4, LUN 1 on bus 0, port 0
- mt5.0.1
- Tape drive at SCSI ID 5, LUN 0, bus 1, port 0
Because the alias name does not change unless you change how the device is
physically attached, always use the alias name for devices that are controlled
by Windows NT device drivers. To distinguish between a real device name
and an alias, TSM checks for a backslash (\) at the beginning of the
name. If the name begins with a backslash, TSM recognizes that the name
is the real device name and not an alias.
- ONLine
- Specifies whether the drive is available for use. This parameter is
optional. The default is YES.
- Yes
- Specifies that the drive is available for use.
- No
- Specifies that the drive is not available for use.
- ELEMent=address
- Specifies the new value to be used for the drive's element address
within a SCSI library. This parameter is optional. TSM needs the
element address to connect the physical location of the drive to the
drive's SCSI address. To find the element address for your library
configuration, access the TSM Web site at:
http://www.tivoli.com/tsm
. At this URL, follow the links to device information. You will
need to click on your product and platform and then scroll to the required
device. When you click on your selected device, you will get the
element address.
- ACSDRVID
- Specifies the ID of the drive that is being accessed. The drive ID
is a set of numbers that indicates the physical location of a drive within an
ACSLS library. This drive ID must be specified as a,l,p,d,
where a is the acsid, l is the LSM (library storage
module), p is the panel number, and d is the drive
ID. TSM needs the drive ID to connect the physical location of the
drive to the drive's SCSI address. See the STK documentation for
details.
- CLEANFREQuency
- Specifies how often the TSM activates drive cleaning. You must have
a cleaner cartridge checked into the library's volume inventory to use
this parameter. This parameter is optional. The default is
NONE.
Note: | Use drive cleaning that is controlled by TSM only for SCSI libraries that do
not have automatic drive cleaning support in their device hardware.
|
- NONE
- Specifies that TSM does not track cleaning for this drive. Use this
for libraries that have their own automatic cleaning.
- ASNEEDED
- Specifies that TSM loads the drive with a checked-in cleaner cartridge
only when a drive reports to the device driver that it needs cleaning.
- value
- Specifies (in gigabytes) how much data to process on the drive before TSM
loads the drive with a cleaner cartridge. TSM resets the
gigabytes-processed counter each time it loads a cleaner cartridge in the
drive.
Usage Notes
- When issuing the DEFINE DRIVE command for a removable drive, a formatted
medium must be present in the drive. For a REMOVABLEFILE device type,
TSM does not supply utilities to format or label the media. You must
use the device manufacturer's utilities or operating system utilities to
format and label the media. Such utilities may include the format and
label commands. The label on the media must not contain more than 8
characters, embedded blanks, or periods. The label must also follow the
operating system's rules for file names. This allows TSM to verify
that a valid file system is available.
- If your SCSI adapter allows the system to see attached drives as either
fixed disks or removable, make sure the system views the attached drive as
removable.
Examples
Task
Suppose you have already defined a manual tape library named MANLIB using
the DEFINE LIBRARY command. You then wish to inform the server that you
have a tape drive that can be used to access storage media. You choose
the name TAPEDRIVE0 for this drive.
- Command:
- define drive manlib tapedrive0
device=mt3.0.0.0
Task
You have already defined a manual library named MANUAL using the DEFINE
LIBRARY command. You now want to inform the server that you have a
stand-alone Iomega Zip drive that is accessed as drive letter H and is ready
for use. You choose the name ZIP1 for this drive.
- Command:
- define drive manual zip1 device=h:
Task
Define drives with element numbers for autochangers.
- Command:
- define drive tapedrive0 device=mt3.0.0.0
element=82
Task
Define a drive in an ACSLS library with a library name of ACSLIB and a
drive name of ACSDRV1.
- Command:
- define drive acslib acsdrv1 device=mt3.0.0.0
acsdrvid=1,2,3,4
Task
Define a drive for a device type of REMOVABLEFILE (CDROM).
Note: | Refer to the Administrator's Guide for more information.
