Does anyone have an idea of how we might have gotten out of this without
an IPL?
VM LPAR has 175G of memory and a flock of Linux Oracle guests...
Several guests needed more memory added so the directory was updated and
one by one the guests shutdown, logged off and back on. So far, so good.
But... In changing the memory for many guests, and it being late at
night after a long day, while meaning to set a guest's memory to 9728M,
it got set to 9728G. When that guest was cycled we see the message on
the console that it's memory was limited to 8TB (HCPLGN093E), then the
VM system appeared to freeze.
We couldn't get in via TCP/IP, or the HMC Operating System Messages
screen, or the HMC Integrated 3270.
Finally had to IPL. Even that was wierd as I'd have expected the Load
Normal to shutdown, it just IPLed. We did NoAutolog, fixed the typo
and all came back up ok...
I suspect CP was scrambling paging everything in the world out as Linux
tried to initialize that 8TB of memory... But I'm surprised I couldn't
even get into the HMC consoles (to kill just that one guest as opposed
to all of them)..
Any thoughts?
