This article is known to apply to an SCO OpenServer system with SCO
     
     OpenServer Release Supplement 504C installed. However, it is
          
possible that it also applies to SCO OpenServer 5.0.4 systems
          without 
RS504C. It has also been reported on OpenServer 5.0.5 
          
systems.

          A SCSI tape has been added to an SCO OpenServer 5.0.4 system.  When
          the /etc/conf/cf.d/link_unix command is run to relink the kernel,
          it fails with these error messages:

                ...
                ...
                Do you wish to create a new kernel now? (y/n) y

                The UNIX Operating System will now be rebuilt.
                This will take a few minutes.  Please wait.

                Root for this system build is /

          If "mkdev tape" is run, it reports two tape units present, but
          there was only one unit configured on the system. For example:

                ...
                ...

                The current tape configuration is:

                     Unit       Description

                       0         Generic SCSI-1 / SCSI-2 tape drive
                       1         Generic SCSI-1 / SCSI-2 tape drive

          If you try to remove the last unit listed, the following message
          appears:

                ...
                Enter the unit number you wish to remove
                        or enter q to return to main menu: 1
                Invalid choice, please enter a number between 0 and 0

                The current configuration is:
                     Unit       Description

                       0         Generic SCSI-1 / SCSI-2 tape drive
                       1         Generic SCSI-1 / SCSI-2 tape drive

                Enter the unit number you wish to remove
                ...
                ...


          The "sdevice", "mdevice" and "mscsi" files in the "/etc/conf/cf.d"
          directory only show one Stp unit listed.

          This problem has been observed where a tape unit has been configured
          and removed several times over a period of time. The same errors
          have also been observed on a system that initially showed the error
          messages listed in the technical article referenced below in the
          "SEE ALSO" section.

          The "/etc/conf/pack.d/Stp/space.h" file contains two entries for
          "gen_Stp_route":

                ...
                Stp_tape_config_t       Stp_tape_cfg[STP_NDRIVES] = {
                /* BEGIN SCO_STP ENHANCEMENTS */
                { 0, 0, -1, -1, gen_Stp_route },
                { 0, 0, -1, -1, gen_Stp_route },
                /* END SCO_STP ENHANCEMENTS */
                ...
                ...

          Edit the "space.h" file and remove the duplicate entry so it looks
          like:

                ...
                Stp_tape_config_t       Stp_tape_cfg[STP_NDRIVES] = {
                /* BEGIN SCO_STP ENHANCEMENTS */
                { 0, 0, -1, -1, gen_Stp_route },
                /* END SCO_STP ENHANCEMENTS */
                ...

          The kernel should now relink without error using the "./link_unix"
          command in the "/etc/conf/cf.d" directory.

          from the link kit."
