Are you using vinum, or do you have a harware raid controller? If it's a
hardware raid controller, you generally need userland utilities to
manipulate the controller and to see failed drives, etc. Normally I
haven't worried about it too much--the controllers I've used have all had
audible alarms so it's very clear when a drive fails, and the front LEDs
reveal the dead one.
