What is the reason to have the tape unavailable? If is just the lack of
slots in the library then the ADSM/TSM way to do it is overflow location as
Stuart pointed.
If it is broken tape or similar - restore volume 000020 from copypool and
then perform reclamation.
Think for status 'UNAVAILABLE' as something bad and for 'DESTROYED' as very
bad. Under normal circumstances you should not have any such volumes.

Subject:        Tape Reclamation

When a tape reclamation starts for tape 000025, the volume is mounted into
the drive, but ADSM also requests the mounting of tape 000020 which is not
in the library (manually marked unavailable).  It is extremely difficult to
reclaim tapes without knowing what tapes are associated to each other.  I
think this is happening when a file is written across tapes.  Is there a
easy way to know what tapes are needed to reclaim one tape?  I would prefer
if there was not a spanning/association across tapes so that when tape
000025 was reclaimable, it could be reclaimed without requiring tape
000020.
A lot of tapes do not get reclaimed because of this.  Does everyone have
this problem or is it something peculiar to me.  I run  ADSM Server for
Windows NT Version 3 Release 1 Level 2.30 on NT 4.0 SP4.   Here is the
activity log:
