If a tape is is marked READWRITE/READINLY, it doesn't become eligible
for reclaimation until it is marked FULL.
If a tape is marked OFFSITE, it becomes eligible for reclamation as soon
as %reclaim is below the STGPOOL threshold.

For most sites, this means tapes in the primary pool don't reclaim until
they become full, tapes in the copy pool become eligible as soon as they
are marked OFFSITE.

I have never seen reclamation take a Filling volume. I thought the Big
Idea ever since the product was called WDSF was to fill up the Filling
volumes until they are Full, let expiration gradually eat holes in them,
and then reclaim them. What's the point in reclaiming a tape that isn't
full yet? Even with collocation, I don't get it. If it isn't full yet,
the only thing you should be doing to it is writing more data to it.
