I'm working with a client who has a Dell Poweredge 1800 with 2 250GB WD SATA drives in RAID 1 on a CERC SATA 1.5/6ch controller. They called the other day claiming that the server was beeping, even after a reboot (though it did reboot successfully). By the time I was able to get on-site, the beeping had stopped, but Dell OpenManage reported that the array was rebuilding - and from the percentage complete it did look like it was rebuilding the entire array.
My question is if anyone else has had a similar issue? Both drives are being reported as OK and online, but nobody would have forced the array to rebuild itself. What could have caused the controller to automatically rebuild the array onto the same disks, and should I be worried that one or both of the disks is on the verge of failure?
