Hi,
I'm trying to get the above 7-slot autoloader working with Amanda.
I'm using amanda versions:
amanda-2.4.2p2-1
amanda-server-2.4.2p2-1
amanda-client-2.4.2p2-1
and mtx-1.2.10-1
on RedHat 7.1
As far as I can tell, my changer device is /dev/sg1 and the non-rewind tape
device is /dev/nst0 (if anyone thinks differently, shout).
mtx -f /dev/sg1 status tells me that I have some slots loaded (loaded slots
are the same as the physical device shows)
I've configured amanda.conf to use the tpchanger "chg-zd-mtx" option, and I've
configured a changer.conf file with the right (hopefully) info.
Each time I su to the amanda user, and issue an "amtape config show", I get the
following error:
bash-2.04$ amtape wibble show
amtape: could not get changer info: badly formed result from changer:
"/usr/lib/amanda/chg-zd-mtx: [: -eq: unary operator expected"
sh -x /usr/lib/amanda/chg-zd-mtx -info shows the following:

Any ideas on whats wrong?
If someone has a working config for one of these AutoLoaders, could they share
it :o)
Thanks,
Mark.
