Guardian Disk and Tape Utilities Reference

Guidelines
• The ALTFILE, PART, and MAP NAME[S] RESTORE options are used to rename files, and the
VOL RESTORE option can be used to change the node, volume, and subvolume of Enscribe
files. Renaming a file can affect device residence, and each of these RESTORE options lets
the volume name be changed.
To restore all files on the BACKUP tape $TURBO to the SMF virtual disk $BRVC4:
RESTORE $TURBO, *.*.*, VOL $BRVC4, LISTALL
• Mapping from the PHYSVOL option is not performed until after the ALTFILE, PART, MAP
NAME[S], or VOL RESTORE options can be applied. You cannot use the original file name;
you must use the last sms-file-specification after applying the other mapping options.
• The PHYSVOL option is not required if the target is an SMF virtual volume. If the PHYSVOL
option is not supplied, the virtual disk process (VDP) selects the location. This is preferred; use
the PHYSVOL option sparingly.
Example
If the tape mounted on $TURBO is a BACKUP of the SMF virtual disk $BRVC3.*.*, to map all the
files from virtual disk $BRVC3 to virtual disk $BRVC4, then ensure that DELME.FILE3 is created on
physical volume $DATA of the $BRVC4 storage pool:
RESTORE $TURBO, *.*.*, MAP NAMES ($BRVC3.*.* TO $BRVC4.*.*),&
PHYSVOL ($BRVC4.DELME.FILE3 ON $DATA), LISTALL
Validation is not performed on the physical-volume-name value.
REBUILD
The REBUILD option specifies that the files in a group of related tape sets are defined by the file
directories on the first tape set. This option only applies to Enscribe files; it has no effect on SQL
files. Any SQL files named in the restore-files are restored as they would have been without
the REBUILD option.
REBUILD
Guidelines
• Use the REBUILD option to restore tapes that were created using the PARTIAL BACKUP option.
• The tape sets that are used with the REBUILD option are usually created using the PARTIAL
option of BACKUP. Start the RESTORE process with the most current tape set. If any files
defined in the directory on the first tape set do not exist on that tape set, RESTORE prompts
you to mount the preceding (older) tape set.
This process of restoring files from preceding tape sets continues until all of the files are restored
or until you terminate the RESTORE process by typing STOP when another tape is requested.
• Attempts to restore multivolume labeled tapes are simplified if an ADD DEFINE command is
used. RESTORE prompts you with a mount message specifying the name of the first tape
expected (as defined in the ADD DEFINE command).
After the first tape is read, a mount message prompts you for the next specified tape. If the
ADD DEFINE specifies no additional tapes, RESTORE prompts you to enter the volume ID of
the next tape (if applicable).
• Any files on the volumes before the REBUILD process begins are retained (REBUILD implies
KEEP).
• You cannot include the REBUILD option in a RESTORE command that converts files from DP2
to DP1 (or vice versa).
