I have managed to get ServeRAID Manager installed on a server and it found a defunct drive. We replaced this drive (slot 3) and it is now ok.
However it is now saying that the drive in Slot 0 is defunct but it was fine yesterday with this error:
Defunt Drive: controller 1, WWN 5000C5000027388C (Vendor: IBM-ESXS Model: ST973401SS F).
I don't want to try and upgrade any firmware while the RAID is critical.
Does anybody know what could be causing it?
