Hi All,
  I'm having a non-critical problem with Bacula in my production
  environment. I have 2 DELL TL-4000 libraries with 2 drives each.
  For each library on the Storage daemon I defined the 2 resources
  for the drives and 1 for the changer:

----------------------------------------------------------------------
Autochanger {
  Name = DELL-TL4000
  Device = DELL-TL4000-Drive-1 , DELL-TL4000-Drive-2
  Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
  Changer Device = /dev/dell-tape
}

Device {
  Name = DELL-TL4000-Drive-1                      #
  Drive Index = 0
  Media Type = LTO-4
  Archive Device = /dev/dell-tape-drive-n0 
  AutomaticMount = yes;
  AlwaysOpen = yes;
  LabelMedia = yes;
  RandomAccess = no;
  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
  Autochanger=yes
}

Device {
  Name = DELL-TL4000-Drive-2
  Drive Index = 1
  Media Type = LTO-4
  Archive Device = /dev/dell-tape-drive-n1
  AutomaticMount = yes;
  AlwaysOpen = yes;
  LabelMedia = yes;
  RandomAccess = no;
  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
  Autochanger=yes
}
----------------------------------------------------------------------

On the director I configured only the changer resource:

----------------------------------------------------------------------
Storage {
  Name = DELL-TL4000
  Address = 10.1.5.109
  SDPort = 9103
  Password = *********************************
  Device = DELL-TL4000-Drive-1 , DELL-TL4000-Drive-2     
  Media Type = LTO-4
  Autochanger = yes
  Maximum Concurrent Jobs = 4 
}
----------------------------------------------------------------------

and I configured the jobs using the following template:

----------------------------------------------------------------------
JobDefs {
  Name = "dbreport_backup"
  Type = Backup
  Level = Incremental
  FileSet = "DB Tables"
  Schedule = "DBWeeklyCycle"
  Storage = DELL-TL4000
  Messages = Standard
  Pool = db-daily
  Prefer Mounted Volumes = no
  Priority = 10
  RunScript {
    RunsWhen=Before
    RunsOnClient=Yes
    Command="/usr/local/bin/bacula_db_stop.sh"
  }
  RunScript {
    RunsWhen=After
    RunsOnClient=Yes
    Command="/usr/local/bin/bacula_db_start.sh"
    RunsOnFailure=Yes
  }
}
----------------------------------------------------------------------

I think the only interesting line from above is 
"Prefer Mounted Volumes = no". 
The problem is that I have the backup running only on the first drive
and not on the second one. Can someone help me with this? 

thanks in advance
Diego
