Basically the issue is that there is a race condition with running MOVE
DRMEDIA on tape volumes while BACKUP STGPOOL is also running. BACKUP
STGPOOL might choose a FILLING volume that
copy pools as part of the client
backup cycle, before BACKUP STGPOOL runs. If that's the case, we might be
able to have our weekly maintenance include MOVE DRMEDIA, and have a hope
of it actually getting to MOVE DRMEDIA during regular business hours.
I'll see how that goes next week.

Good day all,
Looking for some advice on sequential pool copies for long term
archiving. We have the capacity and the drives to define a copy pool for
the sequential pool or create a backup stgpool schedule.

I feel a little sheepish - The log output I save in a file does not have
the ANR2032E message that I found in the actlog, so at least now I have
something to go on. Thanks.
I have a strange problem that I just noticed today - I have not seen it
happen before. TSM 5.2.1.1 on AIX 5.1ML4. I noticed that by tape to
tape backup was backing up more data than usual. My script issued the
command

o the tapepool storage pool a BACKUP STGPOOL is executed to copy this
data to disaster-recovery. Some time later, new data are migrated to the
tapepool again and I would like to know what will happen when the second
BACKUP STGPOOL will be executed.
Will TSM ask the last disaster-recovery tape volum
Andy,
BACKUP STGP does not check headers inside an 'object' on a tape, so if your
file is damaged somewhere in the middle, but both start and end of the file
good, then backup stgpool
will not complain and you will never know that both primary and copy
versions are bad until you do au
