Sorry if I wasn't clear enough.  During reclamation of the offsite tape copy
pool, TAPECOPYPOOL, a volume from our primary onsite
tape pool, TAPEPOOL, was grabbed and used as the output volume for the
reclamation process.  Can anyone tell me why on earth ADSM
would do this?  It should have created a new tape in TAPECOPYPOOL and have
written the data to that volume to be taken offsite,
right?  My concern is that TAPECOPYPOOL is now not an exact duplicate of
TAPEPOOL because the reclamation removed the data from
the four offsite tapes in TAPECOPYPOOL and consolidated it onto a tape in
TAPEPOOL .  Does anybody have any ideas?  Thank you!
