I'm a little unsure on the theory behind tape to tape copying with a single
head drive.  Do I set this up similarly to single head reclamation - tapepool
to disk to different_tapepool??  I've set up single head reclamation but I am
stumped on single head copying.  The copypool doesn't allow me to go tape to
disk and back to tape again ( as far as I can tell. )

TIA, Jeff
