That would be the SCSI verbose messages option. I think the Eric Youngdale consortium added it about Linux 1.2.

Nothing like casually praying the users data hasn't gone for a walk is there. If we don't act on them the users don't report them until something really bad occurs so that isn't an option. Alan
