Yup.  I was trying to set up amanda using chg-zd-mtx.  mtx -f /dev/sg5
yielded info on the changer, and mtx -f /dev/sg4 yielded info on the
drive so I figured tapedev should be /dev/sg4.  When I couldn't get the
tests to work, I looked at the script and discovered that in the places
it accesses tapedev, it uses the mt command.  So, I changed my tapedev
to /dev/nst0 (the "no-rewind" device I usually use with mt), and it
worked like a charm.  Now I'm just trying to figure out how to enable
host control of compression on my Dell PowerVault 120T DDS4.

It comes back with :

bash-2.04# mt -f /dev/pass2 status
mt: /dev/pass2: Operation not permitted

Are you saying i should be able to access
/dev/pass2 as a regular tape drive ?

i read somewhere sometimes you have to use
the changer as tapedev, tried that tho, same
results.
