Our current TSM server uses Shark storage.  We run a 80gb TSM db on 2

A lot of this stuff is still pretty hazy to me, but does that mean
you're not using raw volumes for the DB?  IBM recommended that we use
raw volumes for performance reasons.  We're also running on a Shark.
We have a 60gb database spread across 9 dbvolumes, all raw.
Considering how much Shark I/O is virtual, would we be better off
defining file systems on those partitions and defining multiple DB
vols per partition?
