OK Admins, one more bash! 
Clearly I am being pretty stupid hut would greatly appreciate your
indulgence.
I have recently fitted a TZ877 to an ES40 Tru64 V5.1a. 
This box is in a cluster but the changer is attached to the server local
bus.
When ever I try to use mcutil I get:
root > mcutil -e s:1
mcutil: unknown error
The mcicap file contains:
mc0|TZ877|TAPE1:\
#       :ae:ms:rd:
        :mc=/dev/changer/mc0:\
        :dn=tape1c:\
        :tc=tz877:
# Digital TZ8x7/TZ8x5 DLT Magazine Tape Subsystem
tz857|tz867|tz877|tz875|tz8x7|tz8x5|Digital TZ8x7/TZ8x5:\
        :it=scsi2:dt=tape:ae:re:
All the device files seem OK as below.
