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?
