You can find the CPU serial number and model type in PFXPG, at PFXCPUID. If you are running on a multiprocessor you may have to chase the PFXNXTPF chain and change it the prefix page for each processor.
But... that only affects the CPUID returned by the STIDP assembler instruction. Diagnose 218 returns the real machine CPUID and model number. Newer ISV software does not rely on the easily zapable PFXCPUID (returned by STIDP). Instead they rely on Diagnose 218. A better way is to contact your software vendors and demand a product password good on any CPU. Some will relent when pressed hard enough. If they don't relent, there are still other ways to deal with the issue technically (and provide a good technical challenge).

I have some VSE systems running under the 2nd level system and I would like them to act exactly as during a disaster recovery (to make sure my new license keys work).

The real answer is that for many things, you can get away with ZAPping the CPU type in the virtual machine's VM control block, provided you also zap the "FF" that tells the guest that you're running it under VM. Your mileage may vary! I make no warranties, explicit or implied, as to whether this will cause catastrophic problems with your running guest.

I have been informed that the machine I will be using is a IBM-2064-1C6 with a serial number of 02-00XXXXX Trying to simulate the test now on a 2nd level zVM system. I am presently running on a 9672. I have changed the OPTION statement for this virtual machine adding 'CPUID 0XXXXX' to its directory entry. Will be logging off this machine and re-logging on presently. Since I can't change the cputype on my current system what would be the response from the Q CPUID when I actually use this new machine ? Would it be 'FF0XXXXX20640000' ? Is there anyway I can have the 2nd level zVm system return a different cputype when one either issues the 'Q CPUID' command or uses the DIAG 218 instruction.
