Red lid lightning array defect?

Hi,

I have two compaq ML570 wich have a red light lightning on one disk.
They also have the following error in the event log:
Physical Drive on SCSI Port 2, ID 2 of Embedded Array Controller, has failed. Failure Code: 0x0d.

Compaq Drive Array Physical Drive Status Change. The physical drive in slot 0, port 2, bay 2 with serial number "36126541 0050", has a new status of 3.
(Drive status values: 1=other, 2=ok, 3=failed, 4=predictiveFailure)
[SNMP TRAP: 3029 in CPQIDA.MIB]

Compaq Drive Array Logical Drive Status Change. Logical drive number 1 on the array controller in slot 0 has a new status of 5.
(Logical Drive status values: 1=other, 2=ok, 3=failed, 4=unconfigured, 5=recovering, 6=readyForRebuild, 7=rebuilding, 8=wrongDrive, 9=badConnect, 10=overheating, 11=shutdown, 12=expanding, 13=notAvailable, 14=queuedForExpansion)
[SNMP TRAP: 3008 in CPQIDA.MIB]

What should I do? What should be my first steps to take?
