We originaly had a combination of 3590J and 3590K tapes in the 3494LOCAL
library. I moved the data off of the 3590J tapes and then checked them out
and checked in 3590K volumes that has the same volume labels as the
original 3590J volume. Essentially I replaced all the 3590J tapes with
3590K tapes with the same volume labels. The libary manager was updated to
reflect the new 3590K volumes before they were checked in. Could this have
caused this problem?

Re: 2 3494 Tape libraries seem to
have very different capacities. Any
ideas?
Here is the output from that command. It looks pretty similar to me. I also
checked compression for both local and remote libraries. All are on. We
also run a job every night that deletes the dbb volhistory which allows
only 2 days of retention. (del volhist type=dbb todate=today-2)
STGPOOL_NAME: 3494LOCAL
Unnamed[2]: 38531539
Unnamed[3]: 11776076.83
Unnamed[4]: 11886072.01
STGPOOL_NAME: 3494REMOTE
Unnamed[2]: 38513745
Unnamed[3]: 11773755.03
Unnamed[4]: 11876887.56
These are all great suggestions which is why I asked here but I'm still at
a complete loss.

The output from "select
stgpool_name,sum(num_files),sum(logical_mb),sum(physical_mb) from
occupancy group by stgpool_name" should give some indication of whether
the same amount of stuff is getting to the remote storagepools.

We have 2 3494 tape libraries. One is local and the other is
remote.
The local one (3494LOCAL) receives all the data from the nightly
backups as
it gets migrated from disk. The remote one (3494REMOTE) is only used as
the
target of backing up the 3494LOCAL storage pool which gets done
everyday
during the day. 3494LOCAL has 577 library volumes in it. 3494REMOTE has
494
library volumes in it. Both tape libraries only have 3590K tapes in
them.
My problem is that 3494LOCAL has 62 scratch tapes available and
3494REMOTE has 207 scratch tapes in it. Reclamation runs daily and sets
the
same percentage (57) for both libraries. How can there be such a huge
difference in the number of scratch tapes if both libraries should
roughly
have the same amount of data? It's making me a little nervous that
3494REMOTE doesn't have the same data or something somewhere is going
wrong.
Any ideas?
Thanks,
John
