#*What you are looking for is probably going to be something like /dev/sd**some letter**. In my case, since I installed Fedora on one hard drive first before installing my 3 other disks RAID disks, the above command returns that I have disks labelled /dev/sda /dev/sdb /dev/sdc and /dev/sdd. I, of course, won't be using the hard drive on which I installed Fedora (/dev/sda), so my array will be created using the /dev/sdb /dev/sdc and /dev/sdd disks.
