Staying Prepared for a Disaster (No Tape Management Product)

The following scenario demonstrates the use of the MOVE DRMEDIA and PREPARE commands to generate an up-to-date disaster recovery plan for disaster recovery preparation.

  1. Record the following information in the INSTR.GENERAL stanza source file:
  2. Define a device class with a prefix of DR for TSM volumes:
    define devclass disaster devtype=cartridge prefix=dr
    
  3. Define a copy storage pool, DRCOPYPOOL, associated with the device class defined above. Set the REUSEDELAY parameter to 30 days (which matches the value set by the SET DRMDBBACKUPEXIPREDAYS):
     define stgpool drcopypool disaster pooltype=copy
      reclamation=100 maxscratch=10000 reusedelay=30
    
    Note:
    The reclamation is turned off for disaster copy storage pool so that the partially filled copy storage pool volumes will not be reclaimed before they are moved offsite. You need to schedule the reclamation for your disaster copy storage pool volumes periodically.

Routine Operations

  1. Schedule automatic nightly backups to occur in the following order:
    1. Primary Storage Pools
    2. Database
  2. Daily, create a list of the previous night's database and storage pool backup volumes to be sent offsite:
    query drmedia * wherestate=mountable
    
  3. Eject the volumes from the library. To indicate the ejected volumes that are unavailable for onsite processing, issue the following command:

    move drmedia * wherestate=mountable
    

    This command marks the volumes unavailable to TSM.

  4. Create a new recovery plan:
    prepare
    
    Copy the recovery plan file to a diskette to be given to the courier.
  5. To determine if any tapes need to be returned from the vault, generate a list with the following command:
    query drmedia * wherestate=vaultretrieve
    
  6. Give the courier the database and storage pool backup tapes, the recovery plan file diskette, and the list of volumes to be returned from the vault. Then issue the following command:
    move drmedia * wherestate=notmountable
    
  7. The courier gives you the tapes that were on the previous day's return from the vault list. Update the state of these tapes:
    move drmedia * wherestate=courierretrieve
    
  8. Call the vault and verify that the backup tapes arrived and are secure, and that the tapes to be returned to the site have been given to the courier.
    1. Set the location of the volumes sent to the vault:
      move drmedia * wherestate=courier
      
    2. Set the location of the volumes given to the courier by the vault:
      move drmedia * wherestate=vaultretrieve
