tsm: ULTSM>select stgpool_name,status,count(*) from volumes group by
stgpool_nam
e,status
will tell you if you have a difference in pending tapes.

Here is the output from that command. Looks pretty close on both.
DEVCLASS_NAME GB/Tape

3494CLASS1 40.35
3494CLASS2 40.58
Sigh,
John
So you have about 2 gig of data that hasn't migrated over. Seems
reasonable.
The following query will tell you if you're getting the same amount
of
data on full tapes:
tsm: ULTSM>select devclass_name,cast(avg(est_capacity_mb)/1024 as
decimal(5,2))
as "GB/Tape" from volumes where status='FULL' group by devclass_name

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.
John
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
