Folks,
Many thanks for the swift responses. It does look like it was a path issue,
though even running from root the error was the same. I've removed mtx and
re-installed from RPM and that cleared the problem up. I do, however, have a
few more questions. When I run "chg-zg-mtx -info" I get the following
result:
# /usr/lib/amanda/chg-zd-mtx -info
2 2 1
As I understand the documentation, this means that my current slot is "2," I
have "2" slots and the changer can travel backwards, as noted by "1." Is it
normal for mtx to define "slots" as slots with tapes in them, versus slots
in total? "mtx -f /dev/sg0 status" is aware of all seven slots, and whether
they're empty or not.
Also, if I run "/usr/sbin/amtape cas-unix show" amanda will show the tapes
in the pod, but won't unload the last tape it examined without a manual
"amtape eject." Is this normal, or is there something in the configuration
files quoted below that would prevent the tape pod from unloading the tape
when it was done with it?
