    Dear Managers,

    I have a problem with a tape robot on my system, and I'd appreciate
    some help!

    I have a Tru64 5.1 pk3 cluster (ES40 + DS20) and have recently added an
    MSL5000 tape library with twp DSLT320 drives. This attaches via FC,
    and I believe that the zoning has been set up correctly:

    The system can see all the devices:

        beta # hwmgr view d
         HWID: Device Name Mfg Model Location
         ------------------------------------------------------------------------------
        
          <stuff deleted>
        
          226: /dev/ntape/tape4 COMPAQ SDLT320 bus-1-targ-0-lun-2
          227: /dev/changer/mc2 MSL5000 Series bus-1-targ-0-lun-0
          228: /dev/ntape/tape5 COMPAQ SDLT320 bus-1-targ-0-lun-1

    and I seem to be able to talk to the tape drives OK:

        beta # mt -f /dev/tape/tape4 status
        
        DEVIOGET ELEMENT CONTENTS
        ---------------- --------
        category DEV_TAPE
        bus DEV_SCSI
        interface SCSI
        device SDLT320
        
        <etc.>

    [and I see the same for tape5]

    However, I can't get the Media Robot Utility (MRU) to talk to it:

        beta # setenv MRU_ROBOT /dev/changer/mc2
        beta # robot show robot
        ROBOT /dev/changer/mc2 is not responding: Operating system specific error.

    Until the last weekend, I had an almost identical Neo Overland 2000
    system, connected by SCSI, which the MRU could see and handle fine.
    However, the Neo's SCSI bus seems to have gone down, and I need to get
    backups working again! Can anyone suggest what to look for?

    Many thanks,

    Andrew
