You are absolutely correct: there is one to one mapping of device class and
library.  This is probably not the correct model for the times, however
changing it has major implications.

Moving a client from one pool to another is quite difficult.  The only sure
way is to use export/import.  If your tape pool is collocated you may be
able to use move data commands to get a client's data to another pool.
There is discussion to create a move filespace command that, if implemented,
will give us the ability to move a client's data around.  But until then...

I apologize if I missed the intent of the original question.  Moving some of
the tapes to the other library is not possible.  It's an all or nothing
proposition.
