It could be any number of factors that contribute to it showing up all the sudden.
There are a few things I would look at first: 1) Has load dramatically changed? This could cause extra bus resets. 2) Are you running the latest firmware on your PERC card? 3) Are you running the latest firmware on your enclosure? 4) Are you running the latest firmware on your disk drive? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dave Ewart Sent: Wednesday, July 29, 2009 9:03 AM To: linux-poweredge-Lists Subject: Re: SCSI messages - should I be worried?

My concern is really the fact that we've been running this PowerVault for six months without *any* SCSI sense messages being logged at all - even if they are considered normal - then suddenly two days' ago we started getting them by the bucket load. This is the real issue, I guess. Does the fact that this behaviour has suddenly begun - and always relating to the same physical disk - not suggest that there may be something wrong here? Either with the disk, or with the enclosure slot relating to it?
