I also am getting this error, but I am unable to identify exactly which disk needs to be replaced. Is it reporting the disk to me in hexadecimal?
PERC 3/QC Controller 0, Array Disk 255:255 Sense Key=FF, Sense Code=FF, Sense Qualifier=FF. If this disk is part of a redundant virtual......
lukanicbrian - A SCSI sense key and code of FF is invalid and represents some sort of transient condition that is not being reported correctly. If the disk is offline, then I would suggest you bring it back online and let it rebuild or go through a consistency check. There is not enough information to diagnose the cause of the problem. It may not be hardware at all.
All of the drive and array LEDs are lit up green, and nothing appears wrong with the array. You may be right that it is not a hardware problem. I will perform a consistency check next. Is there anything else I can try?
