Array_0000 is a RAID 10 array. The fourth disk in the array (SN: 0708) has a status of "Missing," yet the drive is also displayed as an independent drive (Internal Disk) with a status of "Normal." On boot up, the BIOS indicates (in bright red letters) that drive 0708 is an "Offline Member."
After receiving this message, I downed the server and replaced drive 0708 with a new drive. But when I attempted to start the server, I received the "Missing Operating System" error and the server would not boot. I then removed the new drive and returned drive 0708 back to its rightful place...so we are up and running. But I would very much like to resolve this problem.
I should also mention that when I click on the "Internal Disk" (drive 0708 with the "Normal" status), there is an option to "Clear and Reset" the disk. But online Help indicates that doing so will "permanently delete existing metadata" on the disk. And since I can't even boot the server without that disk, I'm hesitant to do that.
Has anyone here encountered this problem and, if so, how can I safely resolve this?
