Also you should avoid /dev/st0 and use /dev/nst0 since /dev/st0 can
cause corruption in your tapes.
But I have no choice :
bacula2-64:~/bacula/bin# lsscsi -g

I think you have. Just because /dev/nst0 isn't listed by lsscsi
doesn't mean it isn't there. Look:
[ts@backup ~]$ lsscsi -g
[0:0:0:0] cd/dvd HL-DT-ST DVDRAM GSA-H12N UL01 /dev/sr0 /dev/sg0

crw-rw---- 1 root tape 9, 64 19. Okt 16:59 /dev/st0m
So, I used as you well indicates : /dev/nst0 and /dev/nst1.
Autochanger {
Name = OVL_LTO-3
Device = OVL_LTO-3_Drive-1, OVL_LTO-3_Drive-2
Changer Device = /dev/changerovllto3
Changer Command = "/root/bacula/bin/mtx-changer %c %o %S %a %d"
}
Device {
Name = OVL_LTO-3_Drive-1
Drive Index = 0
Media Type = LTO-3
AutoChanger = yes
Archive Device = /dev/nst1
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
LabelMedia = yes;
RandomAccess = yes;
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}
Device {
Name = OVL_LTO-3_Drive-2
Drive Index = 1
Media Type = LTO-3
AutoChanger = yes
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = no;
LabelMedia = yes;
RandomAccess = yes;
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}
