Specifying Defaults for Tivoli Disaster Recovery Manager

DRM provides default settings for the preparation of the recovery plan file and for the management of offsite recovery media. However, you can override these default settings. To query the settings, issue the following command:

query drmstatus

The output will be similar to the following:

Specifying Defaults for the Disaster Recovery Plan File

The following table describes how to set defaults for the disaster recovery plan file.

Table 33. Defaults for the Disaster Recovery Plan File

Primary storage pools to be processed

When the recovery plan file is generated, you can limit processing to specified pools. The recovery plan file will not include recovery information and commands for storage pools with a data format of NETAPPDUMP.

The default at installation: All primary storage pools.

To change the default: SET DRMPRIMSTGPOOL

For example, to specify that only the primary storage pools named PRIM1 and PRIM2 are to be processed, enter:

set drmprimstgpool prim1,prim2
Note:
To remove all previously specified primary storage pool names and thus select all primary storage pools for processing, specify a null string ("") in SET DRMPRIMSTGPOOL.

To override the default: Specify primary storage pool names in the PREPARE command

Copy storage pools to be processed

When the recovery plan file is generated, you can limit processing to specified pools.

The default at installation: All copy storage pools.

To change the default: SET DRMCOPYSTGPOOL

For example, to specify that only the copy storage pools named COPY1 and COPY2 are to be processed, enter:

set drmcopystgpool copy1,copy2

Notes:

  1. To remove any specified primary storage pool names, and thus select all primary storage pools, specify a null string ("") in SET DRMCOPYSTGPOOL.

  2. If you specify both primary and copy storage pools, the specified copy storage pools should be those used to back up the specified primary storage pools.

To override the default: Specify copy storage pool names in the PREPARE command

Identifier for replacement volume names To restore a primary storage pool volume, mark the original volume destroyed and create a replacement volume having a unique name. You can specify a character to be appended to the name of the original volume in order to create a name for the replacement volume. This character can help you find the replacement volume names in the disaster recovery plan. For details about the restore process, see How Restore Processing Works.

The default identifier at installation: @

To change the default: SET DRMPLANVPOSTFIX

For example, to use the character r, enter:

set drmplanvpostfix r
Recovery instructions prefix You can specify a prefix for the names of the recovery instructions source files in the recovery plan file.

The default at installation: For a description of how DRM determines the default prefix, see the INSTRPREFIX parameter of the PREPARE command section in the Administrator's Reference or enter HELP PREPARE from administrative client command line.

To set a default: SET DRMINSTRPREFIX

For example, to specify the prefix as /u/recovery/plans/rpp, enter:

set drminstrprefix /u/recovery/plans/rpp

The disaster recovery plan file will include, for example, the following file:

/u/recovery/plans/rpp.RECOVERY.INSTRUCTIONS.GENERAL

To override the default: The INSTRPREFIX parameter with the PREPARE command

Prefix for the recovery plan file You can specify a prefix to the path name of the recovery plan file. DRM uses this prefix to identify the location of the recovery plan file and to generate the macros and script file names included in the RECOVERY.SCRIPT.DISASTER.RECOVERY.MODE and RECOVERY.SCRIPT.NORMAL.MODERECOVERY.DRMODE and RECOVERY.NMODE stanzas.

The default at installation: For a description of how DRM determines the default prefix, see the PLANPREFIX parameter of the PREPARE command section in the Administrator's Reference or enter HELP PREPARE from administrative client command line.

To change the default: SET DRMPLANPREFIX

For example, to specify the prefix as /u/server/recoveryplans/, enter:

set drmplanprefix /u/server/recoveryplans/

The disaster recovery plan file name created by PREPARE processing will be in the following format:

/u/server/recoveryplans/20000603.013030

To override the default: The PLANPREFIX parameter with the PREPARE command

The disaster recovery plan expiration period You can set the numbers of days after creation that a disaster recovery plan file stored on a target server expires. After the number of days has elapsed, all recovery plan files that meet both of the following conditions are eligible for expiration:
  • The last recovery plan associated with the database series is older than the set number of days.
  • The recovery plan file is not associated with the most recent backup series.

The default at installation: 60 days

To change the default: SET DRMRPFEXPIREDAYS

For example, to change the time to 90 days, enter:

set drmrpfexpiredays 90

Specifying Defaults for Offsite Recovery Media Management

The following table describes how to set defaults for offsite recovery media management.

Copy storage pool volumes to be processed

MOVE DRMEDIA and QUERY DRMEDIA can process copy storage pool volumes in the MOUNTABLE state. You can limit processing to specified copy storage pools.

The default at installation: All copy storage pool volumes in the MOUNTABLE state

To change the default: SET DRMCOPYSTGPOOL

To override the default: COPYSTGPOOL parameter on MOVE DRMEDIA or QUERY DRMEDIA

Executable commands file name

You can use MOVE DRMEDIA or QUERY DRMEDIA to generate executable commands and store them in a file.

The default file name at installation: None

To set a default: SET DRMCMDFILENAME. For example, to set the file name as /drm/orm/exec.cmds enter:

set drmcmdfilename /drm/orm/exec.cmds

To override the default: CMDFILENAME parameter on MOVE DRMEDIA or QUERY DRMEDIA

Location name for volumes that move to the NOTMOUNTABLE state

MOVE DRMEDIA generates a location name for volumes that move to the NOTMOUNTABLE state.

The default at installation: NOTMOUNTABLE

To change the default: SET DRMNOTMOUNTABLENAME

For example, to specify a location named LOCAL, enter:

set drmnotmountablename local
Location name for volumes that move to the COURIER or COURIERRETRIEVE state

MOVE DRMEDIA generates a location name for volumes that are changing from NOTMOUNTABLE to COURIER or from VAULTRETRIEVE to COURIERRETRIEVE.

The default at installation: COURIER

To change the default: SET DRMCOURIERNAME

For example, to specify a courier named Joe's Courier Service, enter:

set drmcouriername "Joe's Courier Service"
Reading labels of checked out volumes

To determine whether DRM reads the sequential media labels of volumes that are checked out with MOVE DRMEDIA.

Note:
This command does not apply to 349X library types.

The default at installation: DRM reads the volume labels.

To change the default: SET DRMCHECKLABEL

For example, to specify that DRM should not read the volume labels, enter:

set drmchecklabel no
Expiration period of a database backup series

A database backup series (full plus incremental and snapshot) is eligible for expiration if all of these conditions are true:

  • The volume state is VAULT or the volume is associated with a device type of SERVER (for virtual volumes).
  • It is not the most recent database backup series.
  • The last volume of the series exceeds the expiration value, number of days since the last backup in the series.

The default at installation: 60 days

To change the default: SET DRMDBBACKUPEXPIREDAYS

For example, to set the expiration value to 30 days, enter:

set drmdbbackupexpiredays 30
Whether to process backup volumes of the FILE device type

At installation, MOVE DRMEDIA and QUERY DRMEDIA will not process backup volumes that are associated with a device type of FILE.

The default at installation: Backup volumes of the FILE device type are not processed

To change the default: SET DRMFILEPROCESS

To allow processing, enter:

set drmfileprocess yes
Vault Name

MOVE DRMEDIA uses the vault name to set the location of volumes that are moving from the COURIER state to the VAULT state

The default at installation: The vault name is set to VAULT.

To change the default: SET DRMVAULTNAME

For example, to specify the vault name as IRONVAULT, the contact name as J. SMITH, and the telephone number as 1-555-000-0000, enter:

set drmvaultname "Ironvault, J. Smith, 1-555-000-0000"
