The only time I have seen NIP messages (those messages prior to VARY CN(*),ACTIVATE being accepted) on a native MVS LPAR was when the NIP device defined in the IODF was not available, I believe due to some cabling issues. In that situation, all NIP messages were routed to the SE/HMC System Console. I had requested the NIP device be removed from IODF years before, for that exact purpose, to assist with automation that uses SYSCONS, and/or for diagnostics, but due to Fear/Uncertainty/Doubt, the request was flatly denied.
https://www.ibm.com/docs/en/zos/2.4.0?topic=system-nip-console "If no NIP console is defined and ready, MVS™ will use the system console as the NIP-time console." I have zero experience with zVM, so I do not know if that NIP message behavior is the same when MVS is running as a guest. I just figured I would pass along my anecdotal observations. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
