All independent monoplexes, but yes new IPL volumes for the new 2.1 system. No real co-existence, just need to insure viable fallback. Never been able to justify the CPU resources for even basic Sysplex. And never really had the need. We have multiple Lpars to isolate production from development from sandbox work. Part of my concern is that I only have 16 M27 defined. (user to make do with 12 M9 before our last DASD upgrade).
