TSM not grabbing scratch volumes as needed

[Johnn D. Tan]

Something's wrong.

Normally, when one of the storagepools runs out of filling tapes, and
an operation is run that requires a filling tape, TSM will usually
grab a scratch volume and use it.

It is not doing that anymore for any of our storage pools. We have to
manually define a scratch volume to a storage pool. E.g., "def v
restorepool 000116"

Why is this happening? And how can we fix it?

We are runnning TSM 4.1 on an AIX 4.3.3 box.
