Dell RAID array fails to rebuild after replacing bad drive

Well, after replacing a bad hard drive in a client’s server today, the server would show the array as “rebuilding” for about 60 seconds. This was an array configured as RAID 1 on a Dell Perc 3/DC raid controller.

The machine wasn’t under warranty, and I wasn’t sure what to do, other than make sure we had a good backup – because obviously we had lost the redundancy that the RAID 1 array was giving us.

I ended up meeting this guy who had worked for Adaptec and he suggested checking for a firmware upgraded for the RAID controller. I thought, “yeah great idea!” I went on Dell’s website, and check and sure enough there was a firmware upgrade. I downloaded and installed, and after a server reboot, and removing the “new” drive that the server was showing as failed, the controller started an array rebuild and all was well.

Thank the Lord for bringing people across our path at just the right time!
