The array has 6 drive, configured as a mirrored stripe set (raid 10). What is the best way to bring the raid out of the degraded state? Do we have to replace the dead drive or can we do that through the controller?
From the controller look for the bad drive then mark it to be removed then remove the drive and replace with new drive to be the replacement. The controller should either start the rebuild process if not refer to the manual of the controller.
