Ive just spotted an amber disk error message on my 2850, E0D76 BP drive 4 fail. Drives are ULTRA 320 SCSI. Its been a while since this server was set up so I cannot be abolutely sure my memory is accurate but I think it was
Drive 0 73GB
Drive 1 73GB paired as RAID 1
Drive 2 146GB
Drive 3 146GB paired as RAID 1
Drive 4 146GB as hot swap
(I had a dodgy 146gb drive that was giving me flashing amber as a predicted fail but I thought better than nothing to leave it as the hot swap in drive 4)
I think I had the config as
Raid Ch- 0 ID 0 ONLIN A00-00 1 ONLIN A00-01 2 ONLIN A01-00 3 ONLIN A01-01 4 HOTSP
So on checking the config i now see
Seeing drive 4 as failed I removed it , and re-sited it and rebooted but still failed. So I rebooted without it in which gave a POST warning but corrected the LED error from amber to blue.
My question is, can someone with a clue help me figure what has happened, and how can I recover it?
[EDIT] Whats the best way to monitor hardware RAID failure, its PERC 4e/Di controller, OS is Windows Web Server 2008 R2. Can the state of the RAID array be monitored from within windows? Is there some error thrown in the event log that I can hook a warning event on to?

Logical drive 0 (RAID 1) has a failed hard drive or has not been rebuilt. Drive 4 appears to be the mirror of drive 1. Be very careful here and make sure you have a backup of all your data before proceeding. I'd consider placing drive 0 in slot 4 and see if it rebuilds. But, I can't verify from the screen shots which physical drives belong to which logical drives and what sizes they are. At this point be very sure of what you're doing.
EDIT: Looking at the screen shots again it appears that LD0 is using slots 1 and 4 and LD1 is using slots 2 and 3. Confirm the hard drive sizes in the slots and proceed accordingly. (Have a backup!)
