Per,

This MegaRAID controllers have an audible alarm, which I have turned on 
on each system we have. Since I have to visit the lab once a day to 
rotate tapes I will hopefully know if one of the controllers is 
reporting a failed drive.

Additionally FreeBSD will report the array as "degraded" in syslog, but 
I suspect only if you make FreeBSD probe the RAID controller (i.e. 
reboot). Please correct me if I am wrong.

All round, not a good solution, so I'm moving to Adaptec 2200S 
controllers which, as Scott says, are well supported under FreeBSD.
