The number, not the highest number. I often saw gaps in the past. Here is a sample of what my program displays: The CPU model number is 2094. The number of online CPUs is 9. The maximum number of CPUs is 12. The number of GPs online at IPL time was 5. The number of zAAPs online at IPL time was 3. The number of zIIPs online at IPL time was 1. The CPU serial number for CPU 00 is 0328AA2094 (328AA), version code 00. The CPU serial number for CPU 01 is 0328AA2094 (328AA), version code 00. The CPU serial number for CPU 02 is 0328AA2094 (328AA), version code 00. The CPU serial number for CPU 03 is 0328AA2094 (328AA), version code 00. (WLM) The CPU serial number for CPU 04 is 0328AA2094 (328AA), version code 00. (WLM) The CPU serial number for CPU 05 is 0328AA2094 (328AA), version code 00. (zAAP) The CPU serial number for CPU 06 is 0328AA2094 (328AA), version code 00. (zAAP) The CPU serial number for CPU 07 is 0328AA2094 (328AA), version code 00. (zAAP) The CPU serial number for CPU 0D is 0328AA2094 (328AA), version code 00. (zIIP) >Regarding "does not get updated after IPL" you are presumably looking at >the area mapped by CVTSCPIN.
