        Subject: Error Handling for SCSI Controllers

        This list contains the current error codes under
        consideration for the SCSI RAID model.  The long list was
        trimmed at the May meeting by combining and rearranging some
        codes to arrive at the list shown below. The total number of
        new codes is now 21.

        I still think we have gone overboard on combining codes, but
        will defer discussion until George issues the first version
        of the combined document.

        I won't be at the June meeting because of cost concerns
        within Digital.
