Using Tivoli Disaster Recovery Manager with a Tape Management Product

The following scenarios demonstrate the use of the MOVE DRMEDIA command, a tape management product, and the PREPARE command to generate an up-to-date disaster recovery plan for disaster recovery preparation.

  1. TSM server DSMSERV contains the backups for the FileRight Company accounts receivable application.

  2. FileRight uses a tape management product (for example, RMM) to manage its removable media.

  3. For availability management, FileRight uses database mirroring and copy storage pools whose volumes are kept onsite.

  4. For disaster recovery management, FileRight uses database backup and copy storage pool whose volumes are immediately moved offsite after creation.

  5. To prepare for a possible disaster, the administrator records the following site-specific recovery steps in the INSTR stanza source files:

  6. The administrator defines the following TSM and RMM policies for managing their removable volumes for disaster recovery protection:

    1. TSM commands

      • Define a device class with a prefix of DR for TSM volumes:
        define devclass disaster devtype=cartridge prefix=dr
        

      • Define a copy storage pool, DRCOPYPOOL, associated with the device class name defined above. The copy storage pool, DRCOPYPOOL, has its REUSEDELAY set to 30 days, which is the same as for the SET DRMDBBACKUPEXIPREDAYS:
        define stgpool drcopypool disaster pooltype=copy
            maxscratch=10000 reusedelay=30 reclamation=100
        

        Note:The reclamation is turned off for disaster copy storage pool so that the partial filled copy storage pool volumes will not be reclaimed before they get shipped to the offsite location. You need to schedule the reclamation for your disaster copy storage pool volumes periodically.

      • The following DRM system values are used by DRM Offsite Recovery Media processing:
             set drmcopystgpool drcopypool
         
             set drmdbbackupexpiredays 30
         
             set drmnotmountablename dock/031
         
             set drmcouriername hsiaovan
         
             set drmvaultname  ironvault
         
             set drmcmdfilename tsm.drm.exec.cmds
        

    2. RMM commands ( Scenario 1: Tivoli Disaster Recovery Manager Controls Volume Movement)

      All newly created database backup volumes (DR.**.DBB) and copy storage pool volumes (DR.**.BFS) will stay in the home location until they are moved to another location:

           ADDVRS DSNAME(DR.**.DBB) LOCATION(home) DAYS
                  COUNT(99999) STORENUMBER(99999) OWNER(TIVSM)
       
           ADDVRS DSNAME(DR.**.BFS) LOCATION(home) DAYS
                  COUNT(99999) STORENUMBER(99999) OWNER(TIVSM)
      

    3. RMM commands ( Scenario 2: Removable Media Management Controls Volume Movement)

      All newly created database backup volumes (DR.**.DBB) and copy storage pool volumes (DR.**.BFS) will be shipped to an offsite location, IRONVAULT, for disaster recovery protection. The DB backup volumes will be kept in the offsite location until they are expired by database backup series expiration, and the copy storage pool volumes will be kept in the offsite location until they are emptied by reclamation or expiration:

           ADDVRS DSNAME(DR.**.DBB) LOCATION(IRONVAULT) DAYS
                  COUNT(99999) STORENUMBER(99999) OWNER(TIVSM)
       
           ADDVRS DSNAME(DR.**.BFS) LOCATION(IRONVAULT) DAYS
                  COUNT(99999) STORENUMBER(99999) OWNER(TIVSM)
