I set up an area I called movepool and move data from a tape that has
low utilization on it onto this pool then move data onto the current
tape.  My shop is about the same size and I have never missed not
being to do a tape to tape operation as far as ADSM is concerned.
My movepool size 1.5gb and it is adequate.
