ML350 Hard Drive Lights What do they actually mean?

I know the lights indicate status green for ok and red for not very well - but could any one fill me in on a little more detail?

Also whats the best way to trouble shoot a RAID 5 array?

And the best method to rebuild a damaged raid 5 (ie one dead hard disk)

Re: ML350 Hard Drive Lights What do they actually mean?

If you are using an ML350 you can find 2 led on front panel.
LED on the left: System power LED
1) On = System is on
2) Flashing = System is in standby power state
3) Off = System is off

LED on the right: Hard drive Activity LED
1) Off = No hard drive activity on embedded SCSI controller
2) On/flashing = Hard drive on embedded SCSI controller is being accessed

If you are using an ML350 G2
you can see 2 button on 5 LEDs.
Starting from the left to right you have:
1) Unit ID Button
2) Unit ID LED
3) Internal Health LED
4) External Health LED (Power Supply status)
5) NIC Activity LED
6) Power LED
7) Power Button

If you are using an ML350 G3
you can see 2 button on 5 LEDs.
Starting from the left to right you have:

1)Unit ID Button
Off=System off
Blue=Identification
Flashing Blue=Remote concole

2) Internal health
Off=System off
Green=System on, AC power available
Amber=System degraded
Red=System critical

3) External health
Off=System off
Green=System on, AC power available
Amber=System degraded (most commonly due to redundant power supply failure)
Red=Power supply failed

4) NIC indicator
Off=No connection
Green=Linked to network
Flashing Green= System is in standby

5) Power On/Standby status indicator
Off=System off, no AC power
Green=System on, AC power available. Do not remove power from system
Flashing Green=System in standby mode. AC power available. Do not remove power from system.
Amber=System is off. AC power available.

For RAID 5 I suggest you to use auto-rebuild (into Sw provided with the Proliant Server).

Hope this can help you.
