Agreed.  Nothing good will happen if you try to do fulls, and it won't
solve your problem.

ADSM will do RECLAIMS on the partially full offsite 3590's by mounting
the ONSITE copies and creating new, full tapes for moving offsite.

DRM will change the status of the offsite (now empty) tapes to
VAULTRETRIEVE, and they should migrate back onsite regularly.

So I think you have a non-problem.
