o The primary CPU type in a Linux LPAR is IFL. There is no secondary CPU type in a Linux LPAR (IFL only). o The primary CPU type of a z/VM LPAR is CP. Secondary CPU types may be IFL, CF, zIIP, or zAAP. o The primary CPU type of an ESA/390 LPAR is CP. Secondary CPU types may be zIIP or zAAP. You were correct when you said that the specific values are not documented. The values are there to enable correlation between the various SYSIBs that are type-oriented. But it's the question itself that disturbs me. What would software (as opposed to a licence agreement) do with explicit information about CPU type? The capacity of an IFL is the full capacity of the process type, without regard to model. That is, it is unaffected by the subcapacity constraints placed on the CPs. And I suspect that keeping software vendors from going down this road is why the processor type information is, shall we say, obscure at best.
