I'm trying to add a drive to a dell poweredge 2950 running RedHat, which already has two drives in RAID 1. The third drive is intended to be separate and without RAID. I've added a virtual drive using Perc, and initialized it. Now /dev/sdc is present.
run as root gives "Unable to open /dev/sdc". What steps do I need to get the drive formatted mounted and online?
