Hi Roger!
Why don't you use a MOVE DATA against r/o volumes? It has a WAIT=YES
parameter and it's better than using the AUDIT VOLUME command.
When you have a read error on a primary pool volume, the audit command
(with FIX=YES) removes the backup data from the tape. Not a problem for
backup data from the BA client, it gets backed up again next time, but
it is a problem when this is TDP data. Your whole backup series is
corrupted and you should schedule a new full backup as soon as possible.
So my opinion is that r/o issues shouldn't be fixed automatically and
unattended.
Kind regards,

Does anybody have a script or program that can issue a TSM AUDIT VOLUME
command and wait for it to finish - as though WAIT=YES existed?

I keep getting r/o vols in my DEVCLASS FILE storage pools. I want to
audit them before changing them back to r/w. I want an automatic process
to do that, one at a time.

I could have set up this storage pool with preallocated files instead of
letting the operating system allocate and remove scratch volume files,
but dsmfmt on 55TB of space to prepare the fixed volume files would take
a very long time, like about a CPU-year.
