Hey Carmen,
At least you had an operator tell you what they did. :-) Once we determined what had
happened (after a painful middle-of-the-day IPL) the only response I got back from
anybody was "I didn't do anything like that!" But now that I know what that
command does and how it works I doubt I'll ever forget this one.

WOW! this takes me back 20 years when an operator wanted to quiesce a job and
issues that command from the console he called my told me what he did, I
researched what that command does, seemed to me it was like on the old system
consoles O2 and O3 IIRC one was a PSW stop and one a restart, I found the
restart just for grins and it worked, been a long time since I've hear tell
someone had that same experience great find

OK, this is embarrassing. We found the problem - but don't know the culprit. We discovered the
quiesce command wasn't locked down and somebody somewhere keyed it in. The reason we don't know
who/where is because our SDSF-like product had the capability to also do a quiesce and since we
didn't know that's what caused it, we IPLed the LPAR. I did some research after the fact to
determine just how quiesce works (been working on these things for 30 years and never had a reason
to even play with quiesce). Now I know - and I know how to make the machine go again, picking up
where it stopped. PSW Restart from the HMC doesn't do what I consider a "restart" but a
"take the brakes off and let it run". :-)
IBM hardware support found the wait state and informed us of it.
Thanks everybody for the bandwidth and suggestions.

Please do share when you find out!
I wonder if an LPAR with full BCPii authority over the box can silently
query/log information from the HMC for monitoring, i.e., actions occuring not
via BCPii itself, but just accessing HMC logs.

policy took the system out of the plex, XCF may have not seen a heartbeat in a
long enough time it partitioned the system from the plex, I've had this happen
before, you should see some IXC messages if this happened.
when this happened to me there was no indication anyone did anything
the system was just removed from the plex

Nothing out of the ordinary in the HMC logs.

so it looks like one place to check is from the HMC, /console
actions/View control tasks performed, this may get you what you need
another place is from console actions, View console events

I found the log - nothing in it. Heading off to IBM.

Subject: [External] z14 HMC log information
Hi all,
Probably a simple question but I'm not having any luck looking for it so I'm
asking here.
Is there a centralized place on a z14 HMC to show activity occurring, LPAR
activation/deactivation, pretty much anything that happens on an HMC or on a z. We just
took a hit where one of our LPARs and we're not seeing anything. No hardware messages, no
dumps, no nothing. The syslog on the LPAR shows everything running as normal then it just
stopped, 15 minutes later are the IPL starting messages. It almost looks like somebody
hit the "deactivate" button on the HMC so I'm looking for any log info from a
hardware point of view.
Thanks,
Rex
