DFHSM and CBRUXVNL - VOLUME NOT IN LIBRARY INSTALLATION EXIT
Knutson, Sam
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

Has anyone else run into this using the CBRUXVNL exit? Any ideas?
I am just starting to look at this.

Did you found the solution for this issue. We face similar issue in our environment. Please advise.

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.

The issue in our environment is We have recently upgrade to CA1 v12.6 SP0 and CA-Allocate with v12.5
When a application or batch try to allocate a dataset we get the following message
VNL001 VOLUME NOT IN LIBRARY EXIT 253
VOLUME PRODXX UNKNOWN TO SYSTEM
ENTER INTO ANY LIBRARY
If we reply CONT, the application or batch successfully allocates the dataset. We didn't receive this WTOR before the CA1 and CA-Allocate upgrade. There wasn't any change in SMS or storage.

Ok, here's what I can remember ;-) about VNL exit ....
hsm avoids the VNL exit being called because it does its own checking before attempting dynamic allocation of a system managed volume. It knows from its own volume record that the volume is system managed, and checks residency before allocation attempted. So, for hsm's processing there is nothing a product like rmm can do in VNL exit to help .....
So any SYSZTIOT ENQ is purely something to address to hsm.
I did one-time suggest they changed the processing so there was a common path via VNL to resolve the error situation ....
cheers, Mike

This is the old "VNL catches the DASD volume" trick. Did you use the
CA-1 12.6 VNL exit? If so, open a case with CA and Russ will fix it.
If not, get the 12.6 version of the VNL exit installed and retry.

If it was the CA 1 version of the CBRUXVNL exit, the message would start
with a CA 1 documented message ID. I don't see any message id here, which
makes me believe this might be someone else's CBRUXVNL exit. And CA Allocate
does not supply a CBRUXVNL exit, so that is not the cause either. CBRUXVNL
is a simple link-list module, so your first step is to find out whose
version is installed. If you have some type of link-list search tool
(LNKSRCH for example) that can tell you which link-list library it is found
in, you can then look for some eye-catcher.

Someone must have assembled that sample exit and linked it into the system. By default your system would have the rmm version of CBRUXVNL installed in LINKLIB.
So, follow CA-1 installation steps to get the correct VNL exit for use with CA-1.

The easiest process is to use ISRDDN in TSO and type LINKLIST on the command
line. Then on the command line enter MEMBER CBRUXVNL.
You may get a popup panel that asks a YES NO question. Enter YES.
Then see where it finds the member in LINKLIST/LPALIB.
My guess is you have this module in SYS1.LINKLIB and that when you browse
it, it will not be the CA1 version.
