Stephen,

Sorry, not amanda files but system /dev files, I lost track of your
OS but I have a robot on a linux system and have the following in my
amanda.conf file. you need proper protections on both /dev/nst0 and /dev/sg1
or whatever your OS calls your devices.

runtapes 3              # number of tapes to be used in a single run of amdump
tpchanger "chg-zd-mtx"  # the tape-changer glue script
tapedev "/dev/nst0"     # the no-rewind tape device to be used
rawtapedev "/dev/null"  # the raw device to be used (ftape only)
#changerfile "/usr/adm/amanda/solarisbackup/changer"
#changerfile "/usr/adm/amanda/solarisbackup/changer-status"
changerfile "/etc/amanda/agnetha/chg-zd-mtx"
changerdev "/dev/sg1"
