NetBackup never moves tapes to NONE.  You are right that a frozen tape 
is an assigned tape and can't be moved from its current pool.

However, some of us unfreeze the tape and "change" it from it's current 
pool to a "cesspool"  (I use "Baudelaire"), where it sits until I get a 
chance to erase it, test it, eye-ball it or whatever, before putting it 
back in service or discarding it.   The key for me is that I can't erase 
it while it is assigned.  If I just bpexpdate (expire) it, it will go 
back to Scratch and be available for a new write.

Good question!  I have no idea.

You have some options wrt cleaning your tape drives.  If your library 
does it, NetBackup doesn't even see the cleaning tape.  If NetBackup is 
to use them, I think (skepticism = high!) the cleaning tape(s) must be 
in the NONE pool.
