I am working on a SUN T2000 machine with Solaris 10 running on it. When I checked the system this morning, I found it to be turned off. The lastreboot command showed that the system had been shut down the previous night.
I want to find out how the system was shut down. I have run hardware health checks on the system and found no problem. Are there any logs from which I can find out how the system was shut down (Manually from switch or by giving the init 5 command).
The /var/adm messages and the syslog dont have any useful info.
