It is indeed release independent :-) But the bad news is that migration
will start based on 90% of 90 GB :-/
This was once reported to the list - some diskpool volumes become
read-only, 'q stg' shows free space in the pool, but backups go to next
storage pool. You may get error, or go to next tape depending on MAXNUMMP
setting of the node (if maxnummp=0, an error will be reported).

Subject: Migrate disk pool with disk failure
Hello list
A planning question:
I have a disk storage pool of 3 equal-sized volumes of 30 GB each and
highmig=90. How does migration get handled if a disk gets an I/O error and
is set to readonly while the pool is being filled overnight?
With 3 disks, migration starts at 90% of 90 GB, all fine and dandy. With
one disk read-only, you've only got 60 GB to play with.
Does migration now kick in at 90% of 60 GB?
And if not, what happens when you've filled the good disks (approx 60 GB,
depending on how much went on the error disk before the problem)? Does it
go over to tape automatically, or do you get an error?
Our system is TSM server 5.1.6.4 on AIX 4.3.3, but I hope the answer is
release-indepedent.
