It'll be quite unusual to have more than one volume partially full. If TSM assigned pages round-robin, then the usual case would be (fairly) even byte occupancy per volume. In fact, you can observe just this in DISK volumes in a primary stgpool; if you build a stgpool out of disparate sizes, the small ones will get full first. - Allen S. Rout
