I've a Dell Poweredge 2850 that is beeping continuously - 2s beeps with 1s intervals. I'm sure this is because of a degraded RAID - but there's nothing in the Dell OMSA to say so. In fact, the PERC controller is missing from the OMSA.

The server is runnng Red Hat Enterprise Linux (RHEL) 5.7.

How do I shut off the infernal beeping? Can I do it without a reboot? Can I reseat the disk for some extra time while we replace it? And what happened to the PERC controller in the OMSA?

7 months late but this may be of interest:

"You need to go into the BIOS for the RAID controller itself. During post you should see you SCSI or RAID controller initializing saying hit Ctrl-M to configure. In the Config Utility go to Adapter and in this menu you should be able to find Alarm -> Silence Alarm

I did find this and use it - but it doesn't seem to be a "permanent" solution, as the alarm would keep go off again after a period, or after a reboot. There doesn't seem to be a way to completely silence the RAID alarm permanently until a problem is resolved. – Mei Oct 2 '13 at 17:14
