Tivoli Disaster Recovery Manager Controls Volume Movement without the Tape Management Product

This scenario demonstrates how to use the policies defined with TSM and DRM for moving volumes offsite for disaster recovery protection and back onsite for reuse.

Routine Operations

  1. Storage pool backup and database backup processing is performed nightly using TSM central scheduling.

  2. At 8 a.m. the tape administrator issues the following command to create a list of volumes to be given to the courier:
    query drmedia * wherestate=mountable
    

    These volumes were created last night by the server storage pool backup and database backup processing.

  3. The administrator ejects the volumes from the library.

  4. 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.

  5. The administrator then packages the volumes so that they can be given to the courier.

  6. The courier arrives to pick up today's backup tapes. The administrator records that the volumes will be given to the courier by issuing the following command:
    move drmedia * wherestate=notmountable
    

  7. To generate a recovery plan file with the latest volume information, the administrator issues the following command:
    prepare
    

    The administrator copies the recovery plan file to a diskette that will be given to the courier.

  8. Several weeks ago during a scheduled server reclamation processing, copy storage pool volume CSP01 was reclaimed and its volume status was changed to PENDING. The volume is physically located at the offsite vault.

  9. Last night the PENDING window passed for volume CSP01 and its volume status is now EMPTY. Also, a database backup series at vault has exceeded the value specified by the SET DRMDBBACKUPEXPIREDAYS command. The volume no longer contains valid backup data and should be returned onsite for reuse or disposal.

  10. To determine if any tapes need to be returned from the vault, the administrator generates a list with the following command:
    query drmedia * wherestate=vaultretrieve
    

    These tapes no longer have valid backup data on them. Volume CSP01, DBTP55, and DBTP33 are included in the list.

  11. The administrator gives the database backup and copy storage pool tapes, the recovery plan file diskette, and the list of volumes to be returned from the vault to the courier.

  12. The courier gives the tapes that were on the previous day's return from the vault list to the administrator. To update the state of these tapes as returned to onsite, the administrator issues the following command:
    move drmedia * wherestate=courierretrieve
    

  13. The courier drives to the vault with today's database backup and copy storage pool tapes, the recovery plan diskette, and the volumes to return from the vault list.

  14. At 4 p.m. the tape administrator calls the vault and verifies that today's backup database and storage pool tapes arrived and are secure. To set the location of these volumes to VAULT, the administrator issues the following command:
    move drmedia * wherestate=courier
    

  15. The vault also tells the administrator that the volumes on today's return from the vault list have been given to the courier. The administrator issues the following command:
    move drmedia * wherestate=vaultretrieve
    

    This command changes the status for this volume to COURIERRETRIEVE.

  16. Later that week, an audit team from headquarters arrives unannounced and asks the administrator for a copy of the disaster recovery plan for this server. The administrator gives the auditors a copy of the recovery plan file generated two hours earlier with up-to-date information that includes the volumes required for recovery, their location, and the commands required to use them to restore the server. The auditors are impressed by the plan's timeliness and completeness.
