TSM server 5.2.4.4 on AIX 5.2

Due to a capacity "issue" with my libraries, some of my onsite primary pool 
tapes are not resident in my library. So to reclaim my
offsite tapes, I've been checking in tapes that have 90% reclamable space and 
doing a move data on them. I've noticed a couple times
where the tape is in the library, ACC=READO, but when I issue the MOVE DATA 
command against the tape, the tape is never mounted and
the primary pool tapes (that are in the library) are used instead.

The tapes were originally moved offsite with the MOVE DRMEDIA command. I 
brought them back, checked them into the library made them
ACC=READO. I don't understand why TSM isn't doing a tape-to-tape copy??
