Hello, I have a Dell 200S enclosure hooked to a PowerEdge 6350. Here are the details off of my RAID controller:
PERC 2/DC 1.06/22.214.171.124
I am running a 6 drive (73GB ea) RAID5 on the 200S, and an internal RAID1 Mirror on the OS.
There are no error lights on the drives (all green), and the arrays show as ok with the green check mark on the server name within the array manager. Yet in the event tab within the array manager all drives in the 200S (internal drives are ok) show up with a "Sense Key = 5" "Sense Code=21".
I am wondering why that would be when nothing else is indicating a problem? I highly doubt all of the drives would be bad.
You might look at a cable and say "what could possibly be wrong with this - all the pins look fine..." but I've seen otherwise perfectly normal looking cables cause problems with SCSI connections. Point
