We have opened an incident with ADSM support.  Brought a bunch of these
tapes with low utilization percentages back from offsite and set ACCESS
=READWRITE, set the reclaim % down to 80 and reclaim called these tapes
one at a time as expected.  When marked OFFSITE, the starting reclama-
tion message appears for all of the reclamable volumes at once and then
only a small subset are actually reclaimed and marked PENDING and no
messages out of the ordinary are issued.  I'll try a MOVE DATA tomorrow
and see what happens.  It does look possible that the volumes actually
being reclaimed might be from just one collocated node on the local
pool, but I'll have to check that further.

Offsite volume reclamation is designed so that all files needed from a
particular primary volume are obtained at the same time, regardless of
which volume reclamations need these files.  There is no need to serialize
as hypothesized above.

My recommendation would be to work through IBM service on this.  It might
be useful to perform a Move Data on one of the offsite volumes that did
not get reclaimed and look for messages.  Also, be sure to check your
activity log for messages during reclamation processing.  If a volume
cannot be completely reclaimed, a message is supposed to be displayed giving
possible reasons.
