Formatting a Diagnostic Dump Tape
Formatting a Diagnostic Dump Tape
To collect a diagnostic dump, you must prepare a tape with a special format so that it
will accept diagnostic dump data. Use this procedure to format the tape. This
procedure does not do a diagnostic dump.
1. Take the tape drive offline.
2. Press Menu until the Drive Mode Main Menu is reached. “Drv Menu?” is displayed.
3. Press Select to enter the Drive Menu.
4. Press Menu once. “MakeDumpTp”appears.
5. Press Select to start. Any tape cartridge present in the drive is ejected.
6. When “Ld Dump TP” is displayed, place a write-enabled tape cartridge in the drive.
The operation starts automatically and erases and reformats a new tape and gives
it a special dump tape ID coding.
7. ‘When done, exit the Drive Mode.
8. Put the drive online.
Using Labeled Tapes
NonStop systems support two standard tape-label formats:
•
ANSI
•
IBM-MVS
Enabling or Disabling Labeled-Tape Operations using SCF
Use the SCF ALTER SUBSYS command to enable or disable labeled-tape operations.
For example, to turn on labeled-tape processing, enter at a TACL prompt:
> SCF
-> STOP TAPE $* (Stops all tape operation)
-> ALTER $ZZSTO, LABELTAPE ON
-> START TAPE $*
-> EXIT
-> ZSERVER /NAME $ZSVR, NOWAIT, CPU primary-cpu / backup-cpu
Note. Because labeled tapes can be cataloged and offer security features for protecting data,
you should use labeled tapes with 9840 tape drives.
