TSM will use the media that is available. If the copypool tapes are still
READW or READO, TSM will call for their mount. If those tapes are
OFFSITE then TSM will call for primary volume mounts as long as those
tapes are READW or READO. Please note that all this has NOTHING to do
with whether the tapes are in an ATL.

Subject: Re: copy storage pool reclaimation question
Hi Tim
TSM does not physically use the copypool tapes when it runs reclamation as
that would mean getting them back from the off-site location. At this
time,
the copypool volumes would still have critical data necessary for DR
purposes and so must remain off site.
So for example, TSM sees two copypool tapes that are only 40% used. It
copies the data off the primary volumes onto a scratch tape that will then
be marked as mountable and sent off site. Once TSM knows that this new
tape
is in the vault, it will mark the two copypool tapes being reclaimed as
pending. These tapes will come back on site once the reusedelay time is
reached.
I'm quite new to this, and someone may be able to give a more technical
answer, but I hope this helps a little.
Thanks
