If it moves to another machine is it still the same LPAR? From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on behalf of Matt Hogstrom <m...@hogstrom.org> Date: Wednesday, 28 September 2022 at 13:59 To: IBM-MAIN@LISTSERV.UA.EDU <IBM-MAIN@LISTSERV.UA.EDU> Subject: [EXTERNAL] SYSPLEX / SYSNAME / SMFID stability We had an internal debate about the stability of SYSNAME and smfID in a sysplex. The discussion was that smfID is not stable and can be changed and that there can be more than one system in a sysplex with the same sysname / smfid. I haven’t had a chance to try it out but the argument seems to be counterintuitive that anyone would use the same SYSNAME / SMFID in a SYSPLEX.
The IBM documents to not specifically say that it is not allowed but I’m curious if anyone has seen such a configuration / can think of a reason why you would do that. The problem I’m trying to get a handle on is to uniquely identify a z/OS instance over time and the SYSPLEX.SYSNAME seemed like a good combination (I still think that they will be stable over time) but I thought I’d pose the question to the brain trust here. Another proposal was to use the hostname / domain name as unique but it seems that you can have multiple instances of those depending on how many TCPIP stacks you are running in a z/OS instance. Thoughts?
