Re: Server get panic why?

This appears to be related to your question from earlier today, which is here:

http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1440150

You should respond to that one.

As far as this question goes, there is not enough information given to determine a cause of the crash. As suggested in your other thread, you really should contact HP support. That is why you pay them.

Re: Server get panic why?

Maybe a bad port in SAN switches which can create numerous error messages and cause system crash.

Re: Server get panic why?

Hi,

Nothing in here confirms what causes the panic, above IO errors could be caused the a storage enclosure or disk connected.

As suggested above try involving HP to take a look at the latest crash dump stored in /var/adm/crash/crash.X (X file number which holds the images of latest dumps).

Best Regards,
Prashanth
