Greetings.  I've got another reclamation-related question.  I've got some copy
stgpools which, though they are theoretically onsite pools, I'm having to
check out of the library.  In the past, I've worked with this by re-inserting
the volumes which are interesting from a reclamation perspective, but there's
a problem with this strategy:

In order to reclaim a given volume, you really need three different ones: The
target volume, and the volumes "adjacent" to the target: The one with the
other half of the aggregate which comes first on the target volume, and the
one with the other half of the aggregate that comes last.

I don't think I've been able to find a way to find which volumes these are
without actually running the expiration or move data and failing the mount.
Is there a good way to find this information out?

Ideally, I'd like to have my temporary tapehandling methods go something like:

(early in day) Check in all volumes necessary for optimistic reclamation 
workload

(day) Reclaim volumes

(late in day) check out all copy-pool volumes which are 'FULL' and in the
              library.


Does this make sense? Anyone got a hole in that logic?
