Subject:   FreeBSD 6.4/i386 on Proliant DL360 G5 - drive failing but camcontrol says ok?

Hi All,

We've got a number of FreeBSD boxes running proliant DL360/G5's - we have 
stuff on there that periodically does:

"
# camcontrol devlist
<COMPAQ RAID 1  VOLUME OK>         at scbus0 target 0 lun 0 (da0,pass0)
<COMPAQ RAID 1  VOLUME OK>         at scbus0 target 1 lun 0 (da1,pass1)
<COMPAQ RAID 1  VOLUME OK>         at scbus0 target 2 lun 0 (da2,pass2)
"

However, for this machine - there's a red light on one of the drives that 
constitutes 'da1' - yet camcontrol says it's "fine".

We know that camcontrol does change when a drive actually 'fails', and 
shows the various stages the array goes through as it rebuilds with a new 
drive to recover - but this time it's not showing anything very helpful.

Does anyone know if there's some way of getting the 'red light' status from 
the server? - From watching the drives (yeah, highly scientific) the 
machine doesn't appear to be sending any traffic to the drive with the red 
light on :(

I'm going to power cycle the box when I get a chance to see what the 
onboard RAID controller reports for that drive/array - but it'd obviously 
be handy if we could know something was up with it sooner...

-Kp
