George,

I have a Dell PV 132T that allows me to partition the tape library.  I
have to work with the interface to partition and use only the correct
size to report to Networker for the license.  

I also have a Quantum M2500, a close relative of what you have. I have
looked through the doco and I did not see anything in the configuration
options that manages slot counts.  Unless Quantum can tell you
different, I don't believe that you have that option.
