I have a red light on the 2nd internal HD on my 7835H server running CallManager 5 and Linux OS. I know its gone bad and needs to be replaced but this is the 2nd drive in 2 months. I need to find a way to test/diagnose trouble on an internal HD. Since this is runnig Linux OS I'm assuming you can do this through SSH, but I don't know how. I tried looking in RTMT and I didn't see anything to status the HD. Any suggestions?
