Status degraded PERC 5/i

[Robert von Bismarck]

Have you checked the state of the individual disks ?
We had the same problem on a 1950, turned out it was a disk that went over a SMART threshold and gave alarms.
Omreport showed the disk as being in "Non-Critical" state

The "alertlog" on the BMC was full of messages, and we got SNMP traps every 5 minutes about this device.
The disk was alternately blinking yellow/blue on the front of the system. The system's LCD back-light stayed solid blue until we 
pulled the disk to replace it.
We opened a trouble ticket with Dell who diagnosed a firmware issue on the device. The firmware update did not work on the affected disk, so, in the end, it had to be replaced.

Sample output :

# omreport storage pdisk controller=0 pdisk=0:0:0
