Hi George,

Thanks for your feedback. I had a look in /var/log/syslog but unfortunately I can't find anything suspicious just before the time of the crash. We have both DELL OMSA as well as mpt-status installed and you will find below the output of all three commands you have suggested.

As you can see and AFAIK all looks good also the server is green, no flashing orange. So I am really clueless here on what could be going wrong. I just now that this server was working fine for 1 and a half year and suddenly it started to crash randomly with this error message.

Regards,
ML

Usually that means the RAID device has failed. If that were the case,
you'd hopefully have quite a lot of information in the syslog from just
before it locks up telling you about what's going on?

Do you have the Dell Openmanage utilities installed? If so, the output
of "omreport storage vdisk" and "omreport storage pdisk controller=0"
might tell you more.

If you're reluctant or unable to install openmanage, you could try the
mpt-status tool, although I don't know how much information it can give
you - http://www.drugphish.ch/~ratz/mpt-status/

Cheers
