linux machine shutdown by itself

Hi

We got an older linux running SLES9.  Sometimes the machine got shut down during the night by itself.  I don't quite see useful info from /var/log/messages and /var/log/messages-yyyymmdd.gz.  How do I find out the reason?  Where can I check for useful log info?

Thanks.

Rindi,

The machine was purchased about 8 years ago.  We just got limited info now.  I believe it has a RAID.  How do I find out the RAID and test if any drive is bad?  More specific steps are very much appreciated.  

Ganesh4282,

OS is outside of support period, too.  I don't thin Novell will handle this case.
Thanks.

Rindi,

I was hoping you (or somebody) can provide some kind of linux command to find out more about the RAID.  Perhaps I will post another question.

Thanks.
It is different from hardware and RAID controller manufacturer to manufacturer, they provide you with the utilities or tools to diagnose their hardware, or they don't, it depends on them.

To properly check the state of the disks, you also need to run their diagnostics out of the RAID system. There's no Linux command that can do that.

Only if you are using Linux built-in Software RAID do you have some commands to check the state of the array, but also that won't tell you the reason for it failing, or whether the hardware / disks are actually good or not. For that you again have to run the manufacturer's diagnostics.
