Hi All!
I'm new to Amanda and am trying to configure it for
tapeless operation using the instructions in the following
link:
http://amanda.sourceforge.net/fom-serve/cache/191.html. I'm
down to the labeling in step #5 'Use amlabel to label the
tapes'; however, when I run the amlabel command, I get the
following error:
[EMAIL PROTECTED]:/usr/src/amanda-2.5.2/sbin$ amlabel
DailySet3 DailySet301 slot 1
amlabel: could not load slot "1": could not read result
from "/usr/src/amanda/etc/amanda/DailySet3/chg.disk"
I'm running VERSION 2.5.2 on Linux.

recalculated

# You need only specify those colums that should be changed
from
# the default. If nothing is specified in the configfile,
the
# above compiled in values will be in effect, resulting in
an
# output as it was all the time.
# The names of the colums are:
# HostName, Disk, Level, OrigKB, OutKB, Compress, DumpTime,
DumpRate,
# TapeTime and TapeRate.

# Amanda needs a few Mb of diskspace for the log and debug
files,

conf directory
# isn't usually appropriate. Some sites use /usr/local/var

# Create an amanda directory under there. You need a
separate infofile and
# logdir for each configuration, so create subdirectories
for each conf and
# put the files there. Specify the locations below.
# Note that, although the keyword below is infofile, it is
only so for
# historic reasons, since now it is supposed to be a

-----------------------------------------------------------
And my 'chg.disk' file:
# config file for the chg-multi tape changer program.
# Used when tpchanger "chg-multi" is specified in
amanda.conf.
# chg-multi supports several configurations, with or
without an actual
# changer. Please see docs/TAPE.CHANGERS for a description
#
# chg-multi should actually work directly with any changer
that allows
# access to the slots via Unix devices that look to
software like
# regular tape drives. (that is, you don't need a changer
driver...).
# Configuration variables:
#
# 'multieject': use an 'mt offline' command to change to
the next
# tape, or multiple such commands for skipping several
tapes at a
# time.
#
# 'needeject': this option is incompatible with
'multieject'. This is
# needed for changers accessed through several virtual tape
# devices, when the changer needs the current tape to be
ejected
# before changing to another device.
#
# 'gravity': set this to 1 if the changer/stacker is unable
to loop
# back to the first tape after unloading the last one, or
if you
# don't want amanda to go through the tape stack looking
for the
# exact tape it wants instead of using the first acceptable
one.
#
# slot X: The configuration file should list as many 'slot
X'
# statements as the number of slots supported by the
changer or the
# number of separate tape drives used.
# For changers that need an 'mt offline' to load the next
tape
multieject 0
# Is this a gravity stacker that can't go backwards or
cycle ? If
# yes, set gravity to 1.
gravity 0
# Does this tape-changer need an explicit eject command
before loading
# a new tape? If you are using multiple drives as a tape
changer, you
# don't want to do this, but if you are using an
auto-changer that
# allows access to the slots through Unix tape devices, it
might block
# the mount of a new slot until the old is explicitly
ejected. In
# that case, set needeject to 1.
needeject 0
# On some machines there is a delay between when the eject
command
# finishes and the next tape is ready to be accessed. Set
ejectdelay
# to the number of seconds to wait after an eject command.
This will
# almost certainly be needed if multieject is set, probably
not if
# needeject is used.
ejectdelay 0
# Names a status file where the current ``changer'' state
is stored.

I'm hoping that some experienced set of eyes will be able
to point me in the right direction; I've spent a lot of
time on this and am spinning my wheels, so your help is
greatly appreciated! Thanks in advance for your time and
expertise!
Thanks much,
jg
