Restarting the services didn't work, but rebooting the server did. Thanks!
We had a drive fail in an R720, and when we went to replace it, it didn't attempt to rebuild the new drive. We removed the new drive and left the slot open, and Server Administrator shows the slot as being "Spun Up" with a state of "Failed", even though there isn't a drive installed. I'm hoping a reboot will sync the controller back up, so is there any danger to rebooting the server with one drive missing?
R720 failed and removed HDD shown as "Spun Up"
