This may be common knowledge for HDS customers, but you do need a
"Compatible PAV" license on the subsystem in order to install your
HyperPAV license.
HyperPAV rocks, but watch your RMF queuing reports {or MXG or whatever)
to ensure you're not experiencing delays from alias shortages.

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.
