Tom, your changer file contents and what chg-zd-mtx is finding are not the
same. The error message and the debug configuration both indicate lastslot is
1. Be sure that your amanda.conf in the gt-host directory points to the
correct changer file. From my amanda.conf file:
# modified to support Treefrog
tpchanger "chg-zd-mtx.ccserv" # the tape-changer glue script
tapedev "/dev/nst0" # the no-rewind tape device to be used
changerdev "/dev/sgd" # the mtx control device
#rawtapedev "/dev/null" # the raw device to be used (ftape only)
# changerfile is a prefix for chg-zd-mtx. we point to the /usr/adm/amanda/daily
# directory.
changerfile "/etc/amanda/daily/changer"
And my changer.conf file is in /etc/amanda/daily. It has
# From /usr/local/src/amanda-2.4.4/changer-src/chg-zd-mtx
#
# Here is a commented out example file with all the variables and showing
# their default value (if any):
####
firstslot=1 #### First storage slot (element) -- required
lastslot=12 #### Last storage slot (element) -- required
cleanslot=15 #### Slot with cleaner tape -- default is "-1"
# #### Set negative to indicate no cleaner available
#
# # Do you want to clean the drive after a certain number of accesses?
# # NOTE - This is unreliable, since 'accesses' aren't 'uses', and we

# # ALSO NOTE - many modern tape loaders handle this automatically.
#
AUTOCLEAN=1 #### Set to '1' or greater to enable
autoclean=1 #### Set to '1' or greater to enable
#
autocleancount=50 #### Number of access before a clean.

My changer script is /usr/lib/amanda/chg-zd-mtx.ccserv. As per the
instructions in the header, when I run it from the /etc/amanda/daily directory
with the -info switch I get:
[root@softserv2 daily]# /usr/lib/amanda/chg-zd-mtx.ccserv -info
4 12 1 1
[root@softserv2 daily]#
The second number is the number of slots which for you should be 7.

Hi,
NEC autloader with 10 slots and IBM ultrium tape drive.
mtx version 1.2.17
amanda-2.4.4
dmesg -
Vendor: IBM Model: ULTRIUM-TD1 Rev: 1CSG
Type: Sequential-Access ANSI SCSI revision: 03
(scsi0:A:2): 40.000MB/s transfers (20.000MHz, offset 8, 16bit)
Vendor: NEC Model: LL0101H-0A Rev: 0002
Type: Medium Changer ANSI SCSI revision: 02
I can control this robot with mtx fine - I have noticed that i need to do a
mt -f /dev/nst0 offline before i can unload but other than that mtx is fine
and i can load and unload happily.
The problem comes when doing, at the moment, an amlabel.
the first tape loads and labels fine with a
$ amlabel -f gt-host gthost01 slot 1
labeling tape in slot 1 (/dev/nst0):
rewinding, reading label gtlto01, tape is in another amanda configuration
rewinding, writing label gthost01, checking label, done.
then when trying the next
$ amlabel -f gt-host gthost02 slot 2
amlabel: could not load slot "2": Cannot find slot 2 in slot list ( 1)
an mtx status gives me
$ mtx -f /dev/sg3 status
Storage Changer /dev/sg3:1 Drives, 9 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag =
Storage Element 1:Empty:VolumeTag=
Storage Element 2:Full :VolumeTag=
Storage Element 3:Full :VolumeTag=

Storage Element 5:Full :VolumeTag=
Storage Element 6:Full :VolumeTag=
Storage Element 7:Full :VolumeTag=
Storage Element 8:Empty:VolumeTag=
Storage Element 9:Empty:VolumeTag=
This is whats in my changer file
firstslot=1
lastslot=7
cleanslot=8
AUTOCLEAN=0
autocleancount=99
havereader=0
offlinestatus=1
OFFLINE_BEFORE_UNLOAD=1
tapedev=/dev/nst0
I think this is because of the drive needing an offline before an unload but
i thought this should have been taken care of in the change.conf
