I had similar problems once but with an ES47. If the problem was or is the fan, then high temperatures may cause that your server won't boot. What is the error that you get when booting?

In our case, when the temperature increased, a memory module started to have problems.

When the server crash, at the SRM run:

show power

To check the power and environmental status.

You should check your binary.errlog with dia, and /var/adm/crash/crash-data if exists.

As usual, my recomendation is to install webes, the Crash Analysis Tool will help a lot.

Hassan,

Have you checked /var/adm/messages for any errors. If not there check /var/adm/syslog.dated/current/daemon.log and kern.log. When we had a server overheat there were messages in the file.

It sounds like the fan is failing after a couple of hours and the system shuts itself down.

Hi,

If you want to keep running your server, you can rename S51envmon file from /sbin/rc3.d, which will stop monitoring your environment and system will run even if the temperature raises. This is temporary solution. You have get the fan replaced but till that time you can continue your server working.

Thanks
Harman

Two entries before the author posted:

evmalert(700) system panic: pinc(cpu0):domain panic promoted

indicating that there was an AdvFS domain panic, promoted to a system panic, probably because the domain involved was root_domain.

Bad news, hopefully you have a recent vdump of the root.

Rgds,
