I am wondering why TSM goes by Pct Migr rather than Pct Util to decide when to migrate the storage pool. We are fairly disk constrained right now. A couple of times a week, large database is backed up, that keeps Pct Migr and Pct Util far apart. The storage pool fills up, but migration has not kicked in because Pct Migr is 30% to 40% lower than Pct Util. I could adjust my levels, but it doesn't make sense for TSM to let the storage pool fill up. Thanks.
