Is cache=yes on that pool?  Are you talking about percent utilized or percent 
migratable?  I'm reasonably sure you know the difference but thought I'd 
confirm...

I'm looking at 'first causes' for my off-site copy imbalance in my primary 
archive pool - and I've run into something 'interesting'.

Some background -

The archive pool (called ARCHIVEPOOL) has 5 disk volumes, all at 8 GB. Max file 
size is 5 GB. Migration threshold is 60%. Maxproc is 2.

So when we reach 60% or above in the pool, two processes kick off. And we 
migrate all the way down to 0%.

But what I see in the log looks like this:

ANR0984I Process 4758 for MIGRATION started in the BACKGROUND at 02:26:20.
ANR1000I Migration process 4758 started for storage pool ARCHIVEPOOL
automatically, highMig=60, lowMig=0, duration=No.
ANR0513I Process 4758 opened output volume 444019L4.
ANR1001I Migration process 4758 ended for storage pool ARCHIVEPOOL.
ANR0986I Process 4758 for MIGRATION running in the BACKGROUND processed 256
items for a total of 7,094,272 bytes with a completion state of SUCCESS at
02:26:22.
ANR0984I Process 4759 for MIGRATION started in the BACKGROUND at 02:26:23.
ANR1000I Migration process 4759 started for storage pool ARCHIVEPOOL
automatically, highMig=60, lowMig=0, duration=No.
ANR0513I Process 4759 opened output volume 444019L4.
ANR1001I Migration process 4759 ended for storage pool ARCHIVEPOOL.
ANR0986I Process 4759 for MIGRATION running in the BACKGROUND processed 256
items for a total of 8,732,672 bytes with a completion state of SUCCESS at
02:26:25.
ANR0984I Process 4760 for MIGRATION started in the BACKGROUND at 02:26:27.
ANR1000I Migration process 4760 started for storage pool ARCHIVEPOOL
automatically, highMig=60, lowMig=0, duration=No.
ANR0513I Process 4760 opened output volume 444019L4.
ANR1001I Migration process 4760 ended for storage pool ARCHIVEPOOL.

For several hours. For some reason the pool is over 60% full; migration kicks 
in and 15.7 MB migrates; the migration ends; and the pool is STILL over 60% 
full. Why?? More importantly, how do I fix this?

Thanks -

Tom
