In such cases a controller log is helpful.
This you can extract per megacli on this machine or openmanage if running.

Fully agree to check fw and a disk for pred. fail.

Betreff: Degraded Enclosure and now RAID problems

Check if any subsystems have asserted predicted fault.  You may need to replace said subsystem element(s).

You can, in fact I believe $orkplace has just done so on a 2950. The
first google hit for "Enclosure 0:1:0 [Backplane] on controller 0 is
Degraded" implies that this may be to do with firmware versions
though. You might also want to find out what openreport command the
openmanage check is getting its information from and see if that has
any more details.
