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?
