• To restore the file from the first backup session, use the ADD DEFINE. You must specify the
GENERATION and VERSION. Otherwise, their default values would be for the latest backup
performed.

Restoring in Volume Mode
In volume mode, RESTORE copies an entire tape to a disk volume. Only the super ID (255,255)
can run a volume-mode RESTORE process.
When performing a volume-mode RESTORE process:
• The disk volume must be in the DOWN state.
• Do not restore an outdated tape. The effect is similar to using SCF to bring up an old version
of a volume. Therefore, the same considerations for the SCF START command apply. For more
information, see the SCF Reference Manual for the Storage Subsystem.
• When restoring to a mirrored disk, neither mirror should be up during the process. If only one
mirror is being restored, the other mirror should be in the DOWN or HARD DOWN state.
When restoring to only one mirror, RESTORE checks that the other mirror is in the DOWN or
HARD DOWN state, and terminates the RESTORE process if this is not the case.
• Do not use volume mode to restore the system disk ($SYSTEM), because the operation requires
both mirrors to be DOWN which is an unreasonable state for $SYSTEM. Do not back up
$SYSTEM in volume mode unless there is a good reason. If you must back up $SYSTEM in
volume mode, do so only after carefully considering that the disk must be restored under a
different name.
• RESTORE can restore a volume-mode backup tape to any disk volume that has the same or
greater capacity.
• The disk process type of the target disk in a RESTORE process must be the same as the disk
process type of the disk image on tape.
