I have a Dell PowerEdge R720 with a PERC H710P Mini controller. I currently have 10 disks in a RAID10 array, and I need to expand the array, or create a new virtual disk with 2 new 1.2TB disks I have.
Can I plug the new hard drives into the server without taking it offline? Or is this a bad idea, and should I just wait until we can shut the server down? The drives are Enterprise 10K 1.2TB Dell drives.
