Don't forget the performance data - it has the ability to show lots of
issues in very fine detail.

Last week, while I was out of the office, we had our first unplanned
z/VM outage.
We are running z/VM 5.3 with about 20 guests. Symptoms were that a user
tried to access a Linux guest to do a production code move around 10:00
PM. He was unable to get in. Then, the operators received lightening
bolt messages and nothing on z/VM or any of the Linux systems were
available.
The ultimate resolution was to re-IPL. All was fine afterwards.
My dilemma is that I'm not accustomed to debugging z/VM. I'd really like
to look at the system logs for that time to see if there are any
messages. I know that can be done, but for the life of me can not find
any procedures to do it.
Any help would be greatly appreciated.
