Mike,

You need to check in two places for the drives to be used properly.
One is on the schedule level of your class, what is the MPX factor. An
MPX factor of 3 will send 3 clients to the same storage unit provided that
the storage unit has an mpx factor of 3 or more. Also check the Storage
unit for the MPX factor and the number of drives. It sounds like you have
the number of drives defined as 1 and an mpx factor of 3 on the Storage Unit.
Hope it helps.
