Thanks. I'll have to see what we used in our sysplexes that were using WLM PAVs prior to HYPERPAV. I'm fairly sure that WLMPAV=YES was left on because we weren't sure if we were going to get someone to pay for HYPERPAV when we started our latest DASD migration. In some of our other sysplexes, we shared DASD between sysplexes so WLM PAVs were never turned on anyway and we used static PAVs. I don't think it would be a concern if we lost the 2nd set of I/O control blocks in the (previously) WLM PAV sysplexes since we don't page much and local page data sets are entire 3390-27 volumes these days (1 local per volume). The other sysplexes sharing DASD had static PAVs and ASM would have never used them regardless, so we didn't lose anything by not specifying WLMPAV=YES when we migrated to HYPERPAV in those environments.
