This is for static PAVs. YMMV. If you can use WLM assigned PAVs instead of static PAVs, do so. We still run with the static PAVs in one environment that shares DASD between two sysplexes (MII) to prevent any PAV "alias thrashing". The other environments now run with dynamically assigned aliases (WLM). EMC didn't always support that but I'm pretty sure all the DMX boxes do and probably the older EMC boxes do at the proper microcode levels.
