Tom, IIRC, zAAPs and zIIPs have their own pools and should not factor into the ratio. IFLs would not be recognized by z/OS, so that should be a non-issue.
I think Walt Caprice or someone else from WSC did a SHARE presentation on this recently.

Consider a z9 processor with CP, IFL, zAAP and zIIP processors ... with "n" LPARs, all with both defined and reserved LPs in case someone invokes CUOD managed by IRD - which can and will (and does) fiddle with the number of online LPs in the various LPARs. The logical:physical ratio is not a constant, it's become a variable. How do IFL, zAAP and zIIP factor into the logical:physical ratio?
