One easy option is to use separate LCUs for each system, so they don't share any dasd.
Also, the odd LCUs are on primary on the first controller, and the evens are primary on the second controller. Assigning the odds to one system and the evens to the other system would reduce I/O overlap, but if one side is busy (or down for an IML) it will go to the other side.
