To enter tape volumes into the library under the direction of the
exit, the following conditions must both be met:
- OAM must be up and running on at least one of the systems sharing
the tape library dataserver in the SMS complex or TCDBplex.
- OAM must have been started since the most recent IPL on the system
running the requested job.
When entering a volume into a tape library under the direction
of CBRUXVNL, you must set the volume use attribute to PRIVATE; otherwise,
the request fails. This is because only specific volume requests are
handled by the exit and a specific volume request for a scratch tape
is not permitted. Volume use attributes are set by default from the
ISMF Library Definition or by the cartridge entry installation exit.
Perform the following steps when you enter a volume into a tape
library:
- Locate the requested volume using the tape management system inventory.
- Enter the volume into a tape library (or if indicated, the specific
tape library). For a logical volume, enter the required exported stacked
volume and initiate a single volume import at the library manager
console.
- Reply to the outstanding WTOR at the MVS console.
Note: If the exit is waiting for an extended period for human intervention
to finish processing, this causes delays for other jobs that may be
processing at the same time or that may need the same resources as
the job for which the exit is active. If the volume is not entered
into the library within 15 minutes, CBR3646D is issued indicating
that the operator should retry or cancel the job request.
