There is a physical DC with a Raid 1 Mirror, 2 Physical Disks, 500GB each. Dell Server Administrator is installed on the DC, and is reporting both physical disks are fine, online, in a good state etc. On a PERC S300 Raid Controller:

Physical Disk 0:0 Physical Disk 0:1

However at the same time it's reporting that a virtual disk is degraded, what exactly does this mean? The virtual disk indicates it's State is in a Raid 1 Layout. Device Name: Windows Disk 0

If my understanding is correct then the Virtual Disk, when you drill down into Dell OpenManage should have both physical disks as members, as it is a mirror? Is this correct? However, when I drill down into the Virtual Disk, it only displays Physical Disk 0:0 included in Virtual Disk 1.

I'm very new to server side/raid management etc. just while our server techy is away!

Thanks!
