I had an MVS guest setup with the following directory statements: MACHINE ESA 4 CPU 00 BASE CPU 01 CPU 02
I now know that the MACHINE ESA 4 statement authorizes the guest to use up to four CPUs. I successfully executed a DEFINE CPU 03. However, MVS could not configure the 4th CPU online since it did not know about it at IPL time. Okay but, with the 4th CPU defined and not doing anything, how would one go about safely removing CPU 03 short of an IPL? Yes, I tried the DETACH CPU 03 command and watched the MVS system IPL.
