I have never had a problem predefining either devices or even control units in an IOCDS.
As a general rule there should not be any problem especially with *device sensing*. Absent any Hiper's I would go ahead and define the full set.

I was wondering if the unit numbers on the controllers have to match the IODEVICE units.

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.
