Do you have arcconf installed? You could to arcconf getconfig 1 (or whatever your controller number is) to grab some information regarding your controller and the HDDs connected to it. Do you have /dev/sg? devices? If so, smartctl -a might work on them. Re the software RAID, I would double check the health of your HDDs before attempting anything.
