Well, since I was "fingered" below ;) here's what I intended to be a
config, in case you don't have it working yet. I am working out of the
directory /etc/amanda/SMGDR0, with an ADIC SC100. Comments below...
/etc/amanda/SMGDR0/amanda.conf (important stuff):
======================8<------------------------------------
tpchanger "chg-zd-mtx"
tapedev "/dev/nst0" (Or whatever no-rewind device you use)
changerfile "/etc/amanda/SMGDR0/ADIC" (I named it ADIC, but can be anything)
changerdev "/dev/sg2" (whatever scsi-generic device the changer is)
======================8<------------------------------------
The changerfile is just a word that is used to name files.
Chg-zd-mtx will create files as such (using above ADIC example):
ADIC-access
ADIC-barcodes
ADIC-clean
ADIC-slot
You will need to create an ADIC.conf (again, ADIC is an example). There
is a template located _within_ chg-zd-mtx (I'm not sure if the general
Amanda documentation has this added yet?), but it will look like this:
/etc/amanda/SMGDR0/ADIC.conf
======================8<------------------------------------
firstslot=2 #### 1st tape slot
lastslot=15 #### Last tape slot
cleanslot=1 #### Slot with cleaner tape
# Do you want to clean the drive after a certain number of accesses?
# NOTE - This is unreliable, since 'accesses' aren't 'uses', and we
# have no reliable way to count this. A single amcheck could
# generate as many accesses as slots you have, plus 1.
# ALSO NOTE - many modern tape loaders handle this automatically.
AUTOCLEAN=0 #### Set to '1' or greater to enable
autocleancount=99 #### Number of access before a clean.
havereader=1 #### If you have a barcode reader, set to 1.
offlinestatus=1 #### Set to 0 if 'mt status' gives an
#### "offline" when drive is offline.
#### Set to 1 or greater if 'mt status'
#### doesn't give and offline, rather an
#### "ONLINE" when drive is online.
OFFLINE_BEFORE_UNLOAD=0 #### Does your tape driver require a
#### 'mt offline' before mtx unload?
======================8<------------------------------------
All the items are needed, cause I'm a sucky programmer. ;)
The cleanslot can be anything, and it doesn't have to be outside the
firstslot - lastslot range. All that it means is "if a cleaning
operation is called, where would the tape be". If you only do the
cleaning manually, you can otherwise use that slot for a regular
tape, and swap it manually before calling the cleaning job, or
whatnot. Mine is set to 1, which is my mailslot, so I can feed it
in without disturbing any tapes.
Hope this helps...
