MSL5000 not responding

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
