Process

To update, expand or decrease the VMF, use the following steps:

  1. Quiesce all system tape activity.
  2. Back up the current Volume Master File.

    Note: For more information, see CATVMFB - Back Up the Volume Master File.

  3. Locate the VMF initialization commands and modify them to reflect all additions and deletions.

    Note: For more information, see CATVMFI - Initialize the Volume Master File.

  4. Use the backup tape created in Step 2 above to restore the VMF.

    Note: For more information, see CATVMFRS - Restore the Volume Master File.

  5. Execute PROC CATVMFXI to rebuild VMF index.
  6. Allow tape activity to resume.

To restore the VMF while CA TLMS is active, use a different data set name. You may also need to apply the tape transactions that occurred since the backup was created.
