I have a Dell R510 server and want to add another drive to it that will be used as a temporary drive while we are doing a data migration. The server has room for 10 hot swap drives and currently has 8 drive bays in use. I purchased another SAS hot swap drive from Dell and inserted into the server (while running) but the new drive does not show in My Computer or even under Computer Management. All drives in the server are SAS. The server is running Server 2008 R2. Should the new drive not appear under Computer Management after inserted? I even waited about 9 hours and then rebooted the server. Any one now how to get the new drive so it is usable?
