Is this a real hardware raid controller? I do not remember the specifics, yet when we did this on HP proliant boxes with hardware raid, we had to play with the config files and setup for the raid *drivers* so to speak On old boxes with raid5 we would be monitoring something like /dev/ida/c0d0 And on newer boxes with raid1 or raid5 we would be monitoring something like /dev/cciss/c0d0 - rh
