Me silly! You are right! I correct it leaving only one tape device named
changer0. I've found the thread you are talking about but, it use a
configuration like old mine (with one autochanger and three tape device
configured in sd.conf).
This is the new:
bacula-sd.conf
AutoChanger {
Name = "multitape0"
Device = vtape0
Changer Command = "/usr/libexec/bacula/multitape-changer %c %o %S %a %d"
Changer Device = /dev/sg0
}
Device {
Name = vtape0
Drive Index = 0
Media Type = 4mm
Archive Device = /dev/changer0
AutomaticMount = yes
AlwaysOpen = no
RemovableMedia = yes
RandomAccess = no
AutoChanger = yes
LabelMedia = no
}
and bacula-dir.conf
Storage {
Name = changer0
Address = 192.168.0.20
SDPort = 9103
Password = "P00io9"
Device = multitape0
AutoChanger = yes
Media Type = 4mm
Maximum Concurrent Jobs = 1

Why not? Using multitape-changer in command line it create the right
simlink /dev/changer0 --> /dev/nst1|2|3.
If I tell bacula to "update slots" it will virtually change the tapes in the
library changing the simlink, and read, one by one, the tapes header.

Take a look at this output:

It call the loaded command but I'v found in docs that it will have to call the
load command! Why?
