Disks that come from a non-Dell reseller will not work. There is a specific software on Dell/Compellent SAN disks to allow them to be recognized by the system.
Model: Compellent Enclosure EN-SC4020   I just popped this disk in the enclosure, to add disk space to a volume: [IMAGE]  Fired up the Storage center, and under Enclosure1\Disks, it has a status of 'Up' No othervalues are populated. I then right clicked on 'Disks' and choose 'Manage Unassigned Disks', but received the message you see in the thread title: "No new unmanaged disks were found." Tried a re-scan for disks, but no help.  Ideas? I was really hoping for a nice easy plug & play to add storage... oh, and the light on the HDD went green.. Thanks, rich
