Colin,
What is the RC and REASON returned by RMS when the mount request is issued to
the "bad" drive?
I assume you've tried the mount outside of VM:Tape using the native DFSMSRM
command and that's why you are suspicious of DFSMS in this case?

Subject: DFSMS/RMS question
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)?
Thanks in advance
