Allowing Tape Remounts

If you specify that CA VM:Backup should allow remounts, CA VM:Backup asks the operator to remount tapes if it:

• Detects a change in a minidisk that spans tapes
• Detects a bad cylinder, track, or block on a minidisk that spans tapes
• Performs a physical incremental backup at the domain-level and determines that the minidisk has not changed since the last backup and that the minidisk spans tapes

Note: If you perform a physical incremental backup at the track- or block-level instead of the domain-level, remounts do not occur if the minidisk has not changed since the last backup.

If it encounters one of these conditions and the backup of the minidisk begins on the current tape, CA VM:Backup repositions the tape to the point where the backup of the minidisk begins and starts backing up the next eligible minidisk. If it encounters one of these conditions and the backup of the minidisk begins on a previous tape, CA VM:Backup asks the operator to remount that tape, then repositions the tape and begins backing up the next eligible minidisk.
