Hi, thanks for choosing Dell. If it is shown as foreign, you need to clear the foreign. Then when the disk turns ready, that’s when you can use hotspare.   [URL]
I have a PowerEdge R620 with a few disk groups. One of which is consists of two degraded virtual disks. Four physical disks are used to form the virtual disks, but one of the drives is shown on BIOS as missing regardless of whether the failed drive or the new drive with the same part number is inserted. I read that the RAID is supposed to be setup with a Hot Spare for automatic drive rebuild, but I guess it wasn't setup that way. So I am wondering if there is really no way to resolve these two degraded virtual disks through the BIOS except through the use of a third party software. Thanks.
