If you do not have a PowerPatch tape, proceed to Step 4.
a. Mount PowerPatch tape.
:FILE TAPE;DEV=TAPE
:VSTORE *TAPE;@.INSTALL.SYS;SHOW
b. Reply to the tape request.
vstore displays a listing of verified files. These files are not being restored to disk.
4. If you have a Reactive patch tape, check it to ensure that it is not damaged.
If you do not have a Reactive patch tape, proceed to Step 5.
a. Mount Reactive tape.
:FILE TAPE;DEV=TAPE
:VSTORE *TAPE;@.@.@;SHOW
b. Reply to the tape request.
vstore displays a listing of verified files. These files are not being restored to disk.
5. If any files are not verified or if you receive any errors or warnings, ensure your tape drive is clean and
repeat the procedure to be sure it is a media problem and not a dirty tape drive.
Run the cleaning cartridge through your DDS drive at least three times to ensure that the drive is
thoroughly cleaned.
If your media is bad, contact your local HP Support Representative.
Validate Your System Backup (Method 1)
If you are using a CSLT (Method 1) to backdate your system, perform the steps in this section.
If you are using a Factory SLT (Method 2) or a Factory Preload Tape (Method 3), proceed to “Check for Disk
Space.”
Before you begin the process of backdating, log on and verify that your backup tape is valid.
1. From the console, log on with the following conditions.
:HELLO MANAGER.SYS,INSTALL;HIPRI
:SPOOLER LP;OPENQ
:STREAMS streams_device
where streams_device is the device number. A common streams_device value is 10.
An LP device must be configured in SYSGEN. Already spooled and streamed messages might display.
2. Validate the backup you created prior to the update process from which you are now backdating. You need
the valid backup to restore the NMCONFIG file.
Use the VSTORE command to make sure that the full backup is readable.
:FILE TAPE;DEV=tape_device
:VSTORE *TAPE;@.@.@;SHOW=OFFLINE;DIRECTORY
If your backup is not valid, you must use Method 2 or Method 3.
