We are in the same state, my db is 180 Gb, 87% utilized. At a high level, one
of the consultants we talked to suggested loading the database onto 2 different
servers and then deleting different storage pools and nodes from each one,
essentially putting part of the database on each server. We are at TSM 5.3 so
would be going to the same OS and were going to keep the same TSM version. One
of the obstacles I have with this method is almost all of my clients belong to
the same copypool so I need to separate them before we can even attempt this.
Once everyone was backing up to their new server, we could export the remaining
nodedata that was backed up since the database backup was done. Good luck with
your split, I will be interested to hear what method you use and how it works
for you.

Subject: [ADSM-L] Splitting the TSM Database into three
Hi All,
We are discussing a way of splitting our TSM database. It is become very big
and slow.
We want to split it into 2 or 3(one will be the manager of the other two)
I don't know how to split it so I am looking for a procedure/steps on how to
do that.
Also, after splitting the database, can I assign different platforms
(AIX/Windows) to the two DBs.
My db is about 200 GBs now and the server is version 5.2.6.0
