Thank you very much for the assistance. I went ahead and modified my
amanda.conf as per your suggestions.

Thanks again, I also modified my scsi-conf file to more closely model
yours. I no longer experience amanda commands / scsi-conf bombing out
on errors, on the contrary, it will now hang when I run typical amanda
commands. For example:
[EMAIL PROTECTED]:/usr/local/etc/amanda/daily$ amcheck daily
Amanda Tape Server Host Check
-----------------------------
Holding disk /ambackup/daily: 109239520 KB disk space available, that's
plenty
Then wait, wait, wait, nada. Process is still running, although idle.
The debug logfile yields:
amcheck: debug 1 pid 83814 ruid 10080 euid 0 start time Tue Jul 29
16:40:52 2003
amcheck: dgram_bind: socket bound to 0.0.0.0.874
changer: got exit: 0 str: 5 15 1 0
changer_query: changer return was 15 1 0
changer_query: searchable = 0
changer_find: looking for NULL changer is searchable = 0
Attached are the updated config files. Thanks again in advance, my
excitement at switching from an old manually changed DLT7000 to this new
SDLT changer is starting to fade to frustration...
