Hello,
first, on Linux it's recommended specify the /dev/tape/by-id/... instead of
/dev/nstX in
the configuration. Look at the output of
lsscsi -g
and
ls -l /dev/tape/by-id/
because the /dev/nstX and /dev/sgX devices are not guaranteed to be persistent
across reboots.
Also, the Drive Index should increment by 1, you have DriveIndex = 0 and
DriveIndex = 2,
that should be DriveIndex = 0 and DriveIndex = 1
Same for the other changer, the DriveIndex must be unique per changer, not
globally.
Example:
[root@bareost02 ~]# lsscsi -g
[0:0:0:0] cd/dvd QEMU QEMU DVD-ROM 1.6. /dev/sr0 /dev/sg0
[2:0:0:0] mediumx STK L700 0105 /dev/sch0 /dev/sg8
[2:0:1:0] tape IBM ULT3580-TD5 0105 /dev/st0 /dev/sg1
[2:0:2:0] tape IBM ULT3580-TD5 0105 /dev/st1 /dev/sg2
[2:0:3:0] tape IBM ULT3580-TD4 0105 /dev/st2 /dev/sg3
[2:0:4:0] tape IBM ULT3580-TD4 0105 /dev/st3 /dev/sg4
[2:0:8:0] mediumx STK L80 0105 /dev/sch1 /dev/sg9
[2:0:9:0] tape STK T10000B 0105 /dev/st4 /dev/sg5
[2:0:10:0] tape STK T10000B 0105 /dev/st5 /dev/sg6
[2:0:11:0] tape STK T10000B 0105 /dev/st6 /dev/sg7
[2:0:12:0] tape STK T10000B 0105 /dev/st7 /dev/sg10
[root@bareost02 ~]# ls -l /dev/tape/by-id/

The config then should look like this:
Autochanger {
Name = "L700"
Changer Device = /dev/tape/by-id/scsi-SSTK_L700_XYZZY_A
Device = L700Drive0
Device = L700Drive1
Device = L700Drive2
Device = L700Drive3
Changer Command = "/usr/lib/bareos/scripts/mtx-changer %c %o %S %a %d"
}
Device {
Name = "L700Drive0"
DeviceType = tape
DriveIndex = 0
ArchiveDevice = /dev/tape/by-id/scsi-350223344ab000100-nst
...
}
Device {
Name = "L700Drive1"
DeviceType = tape
DriveIndex = 1
ArchiveDevice = /dev/tape/by-id/scsi-350223344ab000200-nst
...
}
Device {
Name = "L700Drive2"
DeviceType = tape
DriveIndex = 2
ArchiveDevice = /dev/tape/by-id/scsi-350223344ab000300-nst
...
}
Device {
Name = "L700Drive3"
DeviceType = tape
DriveIndex = 3
ArchiveDevice = /dev/tape/by-id/scsi-350223344ab000400-nst
...
}
Autochanger {
Name = "L80"
Changer Device = /dev/tape/by-id/scsi-SSTK_L80_XYZZY_B
Device = L80Drive0
Device = L80Drive1
Device = L80Drive2
Device = L80Drive3

}
Device {

Device {

ArchiveDevice = /dev/tape/by-id/scsi-350223344ab001000-nst

}
Device {
