A tape is reclaimed when the a certain percentage of data (determined by
the Pct. Reclaimable variable you set on the storage pool) on that tape
has become obsolete, expired.  "Fullness" is a qualification that is only
applicable in the sense "this tape is full of good (valid) data".  As soon
as that percentage is met by a tape, that tape is then reclaimed.  Th
remaining "good" data is copied from the corresponding primary storage pool
tape to an new copy storage pool tape to be checked out that evening.
The reclaimed tape then goes to a status of "Pending".  As soon as the
Reuse Delay parameter is passed (another variable set by you on the
storage pool in question) the tape then goes into the status of "Empty"
(and as DRMEDIA, the state is "vaultretrieve").

That's how reclamaition works.
