That blinky light saved my butt a while back. Blue flash is good..
orange flash is bad.

In the case of Dell's hardware RAID, it quietly implodes and fails to
flash the handy "I'm broken" light on the front of the drive.

Using software raid there is a util called 'mdadm' that as one of its
(many) functions can be set up to email you in the event of a disk
failure.
And, yes, you could alternatively just write a script to monitor the
logs (or /proc/mdstat for software RAID). This is probably the only
way to do it for hardware RAID, absent some provided software.
By default, you'd probably never know, although disk performance might
drop, until enough drives failed to kill the array - this is probably
not the way you want to be notified.

With all the RAID stuff lately, one question came to mind (from someone
who has never used RAID but is thinking about it :)): how do you know
when a disk has failed? Do you just have to keep reading the logs, or
do you configure the system to drop you an e-mail or what? What
does it
do by default?
