RE: monitoring Raid on Debian
Hi Alvin !
I believe it's an American Megatrends card.
Standard DELL PowerEdge 2400 series.
Don't tell me to throw it away, I just got this box running sweet :)
Correct me if I'm wrong...
Theoretically, if a disk fails, Debian shouldn't know anything.....
Something equivalent to DELL's "Fast" software for win32, it would email me, and I would take out the faulty disk and put in another, the Hardware Raid should rebuild itself ?
Am I hoping for too much ? :)

you're choices are limited .. :-)
your monitoring is strictly dependent on which hw raid card you're
using... if you're using 3ware ... they provide some monitoring
if you're using promise ... throw it away ... use software isntead
if raid monitoring is more important than non-functional hw raid
from fastrack series
sw raid works best for most apps we played with
sw raid monitoring ... that might also work for some hw raid ...

by the time there is a problem with raid... it's too late ... its
broken.... :-)
monitoring and emailing wont help ... your users will be screaming
- dead disk, flaky disk drives,
- dead fans, dead power supply, dead cpu, ..
best thing you can do is to do proper backup of their data, so
that corrupted data does not get backed up to overwrite previously
good backups
