Guidelines
• The RESTORE utility verifies the sequence of each tape reel before it begins restoring the tape.
If a tape is mounted out of sequence, RESTORE issues an error message and waits for the
correct tape.
• If a tape drive is unavailable or off-line, or if a tape is not mounted when the RESTORE utility
attempts to process on that drive, RESTORE polls the drive and displays:
$tape: device not ready -- beginning to poll --
The RESTORE process continues in this state until it detects that the drive is ready, with the
correct tape mounted.
Example
To restore a four-reel tape set by using two tape drives:
1> RESTORE ($TAPE1, $TAPE2), *.*.*, MULTIDRIVE
RESTORE reads from alternate tape drives until the tape set is finished. In this example, RESTORE
reads tape #1 from $TAPE1, tape #2 from $TAPE2, tape #3 from $TAPE1, and tape #4 from
$TAPE2.
MYID
The MYID option sets the owner ID of all of the files that are being restored to that of the user who
is running RESTORE. As each file is restored, it is given the default security of the current user.
MYID
Guideline
If the NOMYID option was used during the BACKUP process, the MYID option of RESTORE is
disallowed. For more information, see NOMYID (page 58).
CAUTION: The MYID option does not actually decrease tape security. The security of BACKUP
tapes is always based on physical possession of the tape. Each customer site should have procedures
to control access to BACKUP tapes that contain confidential information.
NOPROMPT
The NOPROMPT option instructs RESTORE not to prompt the user before beginning to read each
tape but to begin when it detects the tape drive is ready.
NOPROMPT
Guideline
To mount a tape for a RESTORE process using the NOPROMPT option:
1. Before starting a RESTORE process, remove the write-enable ring from each tape reel.
2. Enter a complete RESTORE command, including the NOPROMPT option.
3. Because you used the NOPROMPT option, this noninteractive message appears:
$tape: device not ready -- beginning to poll --
Mount the first (or next) tape. For each reel, the process continues when it detects that the
drive is ready.
4. When there are no more tape prompts, the process is complete.
