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. Thanks,
