According to the training manuals for TSM 4.X and 5.X, you should not have
more than 12 DB volumes. Yet we have 16, and at one point we had 32 and saw
no performance degradation. There seems to be no end to the debate on this
issue. We are on AIX 4.3.3 and have been with this config from 4.2.X

Placing TSM DB volumes over multiple physical volumes can improve
performances because the DB is read-oriented, the LVM will spread the load
over the various volumes. if the number of volumes is too high, though,
your performance will be hit by the overhead on the Logical Volume Manager.

Basically it uses DB and LOG volumes by filling up the first

some of the first volumes can be less than 100% full, this

Is it better to create one db volume sized at 33gb on 2 disks, and mirror it

I've moved TSM database components using DFDSS copy

you say, its a lot faster, and easier than using the 'delete dbvolume'
