I think Brian ment only CPs versus IFLs. So you both are right. You can have any number of IFLs regardless of the number of regular CPs (there is an exeption, z9 BC model R has to have at least one regular CP, marketing/pricing/whatever requirement). Besides this model, you can have machine IFL only (there are customers who use this path). Of course, no z/OS on IFL only machine. And you cannot mix CPs and IFLs in one LPAR. zIIPs and zAAPs are different story. You cannot have more zIIPs or zAAPs then regular CPs in your machine. So if you have 3 CPs, you can have max 3 zAAPs and max 3 zIIPs. However, on LPAR level you can have more zIIPs or zAAPs then CPs (if it makes sense) but there must be at least one CP, otherwise you have no engine to IPL.

Brian, That may be true for IFL engines, but, of necessity, zIIPs and zAAPs must be defined to an LPAR with general purpose CPs. Right?
