Ed, Check if you are receiving two controllers with 1 drive each (as coded in your IOCP) or one controller with 2 drives. In the second case, the better IOCP is:

We are getting two IBM System Storage TS1120 Tape Drive Model E05 (3592 E05) with encryption. Do I need to generate a full range of devices? Seems that I remember that z/VM likes to have full ranges even If we physically only have 2 drives.
