If your Solaris system panics and reboots, it'll probably create a crash dump in /var/crash. You can also force a crash dump either online (using "savecore -L") or as part of a reboot (using "reboot -d").
Normally this is where I stop and upload the /var/crash/vmdump.0 file up to Oracle to find out what the problem was. However, you can do some basic investigations yourself using the following steps:
# savecore –f vmdump.0 /somedirectory
# cd /somedirectory
# mdb *0
mdb> ::status
mdb> ::panicinfo
mdb> ::stack
mdb> ::msgbuf
mdb> ::cpuinfo
mdb> ::ps
mdb> ::arc
mdb> ::memstat
(*If the vmdump file is called vmdump.1 then use 1 instead of 0 in the above steps)
Honestly, most of the output is Greek to me but it's nice to know in the off chance something makes sense.
