Hi Phil, Sorry for the long delay.but I had other things to do. Steve may have
a possible solution. Let me put it into terms you can understand.
Steve says there is 1 exception to the hardware console requiring V CN(*),ACT
to become the first active console during IPL. He says if you disable all z/OS
DEV(###) consoles, then the hardware console will automatically activate
because there is no other console available. I believe this to be true but I
have never tried this. There may be a couple caveats that can be discussed
later if it solves your problem.
This is simple to test. From the z/OS VM user, detach all devices specified in
PARMLIB(CONSOL##). At the moment, forget he mentions "NIP" device because this
is almost always included in PARMLIB(CONSOL##) which means you would have
detached it. This is so simple it's worth a try.

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.

"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.
