1-30 User Reference
BIM-EPIC issues these commands during AVR to search for the desired tape on a drive that is
owned by VM.
These commands differ from their IBM counterparts in the following ways:
•
VDETACH detaches the tape drive without unloading the tape. This leaves the tape
accessible for another AVR search.
• Both the VATTACH and VDETACH commands operate in “silent” mode. That is,
they do not issue messages.
At close time, BIM-EPIC releases the tape drive assignment with Early Drive Release and
Autoattach.
Early Drive Release and Autoattach are automatic, but they are inhibited if you use alternate
assignments.
Autoattach cannot detach a drive if the job cancels or when the assignment is held past close
with the TLBL option 8 or DD parameter FREE=END. However, another job on that virtual
machine can be assigned to the drive, and if that job releases the assignment at close,
Autoattach detaches the drive automatically.
BIM-EPIC’s tape initialization program (TSIDINIT) prevents initializing tapes with duplicate
volume serial numbers and adds new tape volumes to the DSN Catalog.
TSIDLBL creates gummed volume labels for your tapes.
Vault management facilities control tape vaulting.
Tapes are added to the DSN Catalog automatically as you process datasets. In most
circumstances, they do not have to be added manually. If you wish to add tapes to the DSN
Catalog manually, use the ADD command (in Online Manager or the TSIDMNT program) or
reinitialize the tapes with TSIDINIT.
You can migrate to cartridge tapes automatically by specifying a cartridge density as the
global default for all output tapes. To do so, use the MODE configuration option.
