Enabling or Disabling Labeled-Tape Processing
The LABELTAPE attribute (page 14-64) of the ALTER command toggles labeled-tape
processing. Although this labeled-tape processing setting overrides the CONFTEXT
entry, it is in turn overridden by the BLPCHECK or NLCHECK options of the
MEDIACOM ALTER TAPEDRIVE command (described in the DSM/Tape Catalog
Operator Interface (MEDIACOM) Manual).
To enable labeled-tape processing:
1. Stop all available tape drives on the system:
-> STOP TAPE $*
2. Enable labeled-tape processing for the system:
-> ALTER $ZZSTO, LABELTAPE ON
3. Restart all available tape drives:
-> START TAPE $*
4. Exit SCF, then start the $ZSVR tape server process:
-> EXIT
> ZSERVER /NAME $ZSVR, NOWAIT, CPU primary-cpu / backup-cpu
To turn off labeled-tape processing:
1. Stop the $ZSVR tape server process:
-> STOP $ZSVR
2. Start SCF, then stop all available tape drives on the system:
> SCF
-> STOP TAPE $*
3. Disable labeled-tape processing for the system:
-> ALTER $ZZSTO, LABELTAPE OFF
