Hi, Burak.

The Admin Guide, in Chapter 9, Managing Storage Pools and Volumes, the
section "Reclaiming Space in Sequential Access Storage Pools" > "Reclamation
for Copy Storage Pools" > "Reclamation for Offsite Volumes" explains what
happens.  It's on page 156 of my Admin Guide 4.2 for AIX.

It basically says that for onsite volumes, reclamation usually happens when
status="FULL" and when the percent reclaimable is greater than the stgpool's
reclamation percentalge.  For volumes with access="OFFSITE", it doesn't
bother with the Full part, it just compares the pct_reclaim.

I hope this answers your question.
