Ricky,

could you please send the output of the following commands:
1.   Q MOUNT
2. q act begint=-12 se=Migration

Also, the only way that the stgpool would migrate back to itself would be 
if there was a loop, meaning your disk pool points to the tape pool as the 
next stgpool, and your tape pool points to the disk pool as the next 
stgpool. If your tape pool was to hit the high migration mark, it would 
start a migration to the disk pool

Nothing out of the normal, the below is kind of odd but I'm not sure it 
has anything to do with my problem. 

Now here is something, I have another disk pool that is supposed to 
migrate to the tapepool and now it's doing the same thing. Migrating to 
itself.

What the heck.

The only oddity I see is that DDSTGPOOL4500 has a NEXTSTGPOOL of TAPEPOOL.
Shouldn't cause any problems now since utilization is 0% but would get 
triggered once you hit the HIGHMIG threshold.

Is there anything in the activity log for the errant migration processes?
