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

Farren Minns
