No that's not it.. it would work regardless.

Doublecheck what domain the node is assigned to and verify it is backing up
with the management class and therefore stgpool you are thinking it should
be.

I'd recommend looking through your activity log on or about where the
problem started and see if TSM logged anything relevant. You can find out
when the first problem occurred by doing a "q act begind=today-7
search=full" or look for the AN msg ID you're getting about the storage pool
being full. Then when you see the time/date stamp, do a "q act
begind=today-? Begint=??:??" and rear around that timeframe to see what
other messages there are. I'm sure something happened somewhere if it was
working and then stopped.
