Thanks to all who responded. There is now a light at the end of the tunnel
:-)
o The TZ877 can be treated as a sequential loader
- Ultrix dump will unload and load cartridges (according to the
TZ877 owners manual.) I guess DU dump and vdump will also do this
(but I haven't tried)
- If you want to use tar, tapes can be unloaded and the next one
loaded (tar doesn't move to the next tape automatically) by using:-
# mt offline, between tars
- I'm told (and would expect) that once the seventh cartridge is
unloaded the first is _not_ reloaded.
- NSR also handles the sequential load and unload of the cartidges
o The TZ877 can be used as a Juke box for random access of cartridges
- CAM medium changer from subset clc300 of the layered products CD.
which provides the mcutil command to manipulate the loader
and MAKEDEV.MC to create the device file for the loader
I haven't looked at this yet - it may need a license
e.g. if NSR jukebox is licensed I can use mcutil.
- Edward Bailey's TZ877 control utility from :-
ftp://moocow.niehs.nih.gov/pub/loader-stuff
which I'll have a look at when I get the time - it sounds ideal
- NSR with the jukebox license option
- DEC will soon ship Media Robot Utility which will allow user
control of the loader with DLT and RDAT loaders.
o I like the look of NSR, so I'm going to use the TZ877 as a sequential
loader. Later I'll try Edward's utility. One day If I get the
money I'll license NSR for jukeboxes
o The device JKB1 was a red herring - its a KZPSA scsi card. The TZ877
is controlled via the SCSI CAM - either with NSR, Edwards utility
or the CAM medium changer

My original question:-
Does anyone have experience using a TZ877 on DU, maybe with Networker Save
and Restore (but this is secondary at present!)
Is the TZ877 treated as a massive tape or can I control which of the seven
cartridges is loaded from UNIX?
from the console I have
MKB500 = the TZ87
JKB1 = the tape changer hardware (I assume)
but from DU I only have the *mt0* files in /dev, no tape changer device.
If I can select a particular cartridge, how is it done? and what device file
is used?
We have no documentation for the tz877, a friend is faxing a copy of her
owners manual - but she says it's a bit vague - typical documentation :-}
