Luc,
The assignment of 'Data Transfer Element 0' to '/dev/nst1' and 'Data
Transfer Element 1' to '/dev/nst0' is done by the kernel.
You can use the 'amtape CONF verify' command to check if you correctly
configured amanda.

Hello Folks,
I’m getting a strange result when I do an ‘amcheck’:
slot 3: Tape device /dev/nst1 is not ready or is empty
slot 4:Slot 4, label '000279L7', mismatch barcode between changer '000280L7'
and tapelist file '000279L7'
ERROR: Slot 4, label '000279L7', mismatch barcode between changer '000280L7'
and tapelist file ‘000279L7'
Here’s what I have in my config file:
define changer spectra-robot {
tapedev "chg-robot:/dev/changer"
property "tape-device” "0=tape:/dev/nst0"
property append "tape-device” "1=tape:/dev/nst1"
device-property "BLOCK_SIZE" "512k"
property "use-slots" "1-47”
}
To get rid of the problem, I reverse the tape device order:
define changer spectra-robot {
tapedev "chg-robot:/dev/changer"
property "tape-device" "1=tape:/dev/nst0"
property append "tape-device" "0=tape:/dev/nst1"
device-property "BLOCK_SIZE" "512k"
property "use-slots" "1-47”
}
Here’s the pertinent lines of the ‘amcheck’ after having made this change:
slot 3: volume '000279L7'
Will write to volume '000279L7' in slot 3.
What going on? If it can help, here’s the output of ‘lsscsi -g’ (I removed the
non-tape + changer lines):
[1:0:4:0] tape IBM ULTRIUM-HH7 G9Q1 /dev/st0 /dev/sg10
[2:0:4:0] tape IBM ULTRIUM-HH7 G9Q1 /dev/st1 /dev/sg13
[2:0:4:1] mediumx SPECTRA PYTHON 2000 /dev/sch0 /dev/sg14
And here’s an output of the first few lines of the command ‘mtx status’:
Data Transfer Element 0
Storage Changer /dev/changer:2 Drives, 48 Slots ( 1 Import/Export )
Data Transfer Element 0:Empty
Data Transfer Element 1:Full (Storage Element 3 Loaded):VolumeTag = 000279L7
Storage Element 1:Full :VolumeTag=000277L7
Storage Element 2:Full :VolumeTag=000278L7
Storage Element 3:Empty
Storage Element 4:Full :VolumeTag=000280L7
I’m using a 50 slot SpectraLogic T50e library with two LTO7 IBM drives.
Thanks!
