I'm sure this is a feature, not a bug - and you can't change it. (Maybe setting HIPERDISPATCH off in IEAOPTxx prior to IPL would change things, but I doubt it?)
For the processors defined as initially online, I think you will always find CPs, then zAAPs, then zIIPs. Then you will see the same order for reserved processors. (at least on an OS with z196 support, I wonder if an OS without that support was IPLed on a z196 if it would assign the LPs like it would on a z10). Physically, the pooling should be the similar to z10, but I didn't find the exact text in the z196 Technical Guide Redbook that I did in the z10 version (I may have missed it). "Processor unit characterization is done at power-on reset time when the server is initialized. The z10 EC is always initialized in LPAR mode, and it is the PR/SM hypervisor that has responsibility for the PU assignment. Additional SAPs are characterized first, then CPs, followed by IFLs, ICFs, zAAPs, and zIIPs. For performance reasons, CPs for a logical partition are grouped together as much as possible. Having all CPs grouped in as few books as possible limits memory and cache interference to a minimum."
