We have been using DFSMS/RMS on VM for a long time. At the weekend we had an issue which, I suspect, has happened before but not been identified.
We have 16 drives per VTS shared between 6 VM systems (VMTAPE STAM) handles the sharing of the drives. Yesterday, on only one of these drives, I was getting a message that there were no scratch volumes available. An identical mount request (for the same scratch pool) in an adjacent drive in the same VTS was satisfied without problems. I think I know what happened - but I am not sure if this is a bug (or how to handle it). What I think happened is this:- When RMSMASTR was started on this system, it went through it's initialisation process but this particular drive was in use at the time. As a result, RMS is confused. If I am right then a restart of RMSMASTR would solve the problem for this drive but create other potential problems with the other drives in use. Because we have drives in use for long periods of time (by TPF test guest systems) it would almost take a system outage to have no VTS drives in use. Does anyone have any experience or knowledge of this situation? If so then :- a) Does my theory sound correct? b) Is this a reportable bug (should I open a PMR)? c) Is there a way to get round this problem (for example: can I get RMSMASTR to reinitialise a specific drive)?
