Hi,
We use IBM's sample CBRUXVNL - VOLUME NOT IN LIBRARY INSTALLATION EXIT with
our ATL. This exit gets driven when a request is made for tape that is not
in the library. The exit prompts the operator with a WTOR
VNL001 VOLUME NOT IN LIBRARY EXIT
VOLUME 217805 SHELF-RESIDENT
DURING JOB STEP SETUP
ENTER INTO ANY LIBRARY
565 VNL002 REPLY 'CONT', 'RETRY', 'CANCEL', OR
'DISABLE'
When DFHSM tries to allocate a tape and it is not in the ATL we see DFHSM
processes get hung with enqueue contention on SYSZTIOT
Hi Sam,
Did you found the solution for this issue. We face similar issue in our
environment. Please advise.

Karthick,
What is your tape management system (CA-1, RMM, etc.)? Do you know why
the HSM tapes out of the library? You should take steps to ensure that
your primary HSM tapes are never ejected. It would be acceptable to
eject duplexed tapes for offsite storage. While it doesn't fix the ENQ
hang, you should be able to prevent it from occurring.
