I will comment on the tape combining.  There are 3 or 4 primary tape pools.
It did not have to be that way.  You could have used the same primary tape
pool for all of the disk storage pools.  However, when reclamation occurs to
my knowledge it will not move primary data from one storage pool to another.
It reclaims within the pool.  So you will have to manually move the data
from primary pools to the consolidated pool.  The copy pools are a different
storage.  There is no command to move them from one to the other.  What you
do there is simply backup the primary to the new consolidated copy pool and
delete the volumes from the old copy pools.

Keep this little tidbit in mind.  Reclamation can only process one volume at
a time in a storage pool.  So when you consolidate you could go from 3 or 4
simultaneous reclamations to 1.

Having a fewer number of storage pools makes managing the TSM server a bit
easier from a sys admin standpoint.

I know this has been discussed somewhat recently so I thought I'd see if
anyone who might have changed and gone this route has any comments.

I've been thinking about combining 3-4 disk/tape pools into one. I thought I
might get better usage of the disk as a whole, instead of some being 30%
full and others overflowing and having to dump to tape during the backups.
If you've had any good or bad experience with this could you pass it on
please?

I would guess from time to time I could "move data" to get the tapes to all
combine. I also think that after time it would all migrate on its own
through reclamation right?

I have co-location on for the onsite tape pools only.

Any info is appreciated.
