This is not needed or wanted.

Loose the first device otherwise it looks fine to me. Here is my
definition for my 2 drive Exabyte Magnum 224:

Autochanger {
  Name = Magnum224-0
  Device = LTO2-0, LTO2-1
  Changer Command = "/usr/libexec/bacula/mtx-changer %c %o %S %a %d"
#  Changer Device = /dev/sg5
# 02/12/2007 added udev rule to link /dev/autochanger1 to the changer
  Changer Device = /dev/autochanger1
}

Device {
  Name = LTO2-0
  Media Type = LTO-2
  Drive Index = 0
  Archive Device = /dev/nst0
  Autochanger=yes
  AutomaticMount = yes;               # when device opened, read it
  AlwaysOpen = yes;
  RemovableMedia = yes;
  RandomAccess = no;
  Spool Directory = /mnt/tmp/bacula/tape
  Maximum Job Spool Size = 5G
#  Maximum Block Size = 262144
#  Minimum Block Size = 262144
#  Volume Poll Interval = 5 minutes
#  Close on Poll = Yes
#  Offline On Unmount = no
  LabelMedia = Yes
  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"

#  Maximum blocksize = 512K
}

Device {
  Name = LTO2-1
  Media Type = LTO-2
  Drive Index = 1
  Archive Device = /dev/nst1
  Autochanger=yes
  AutomaticMount = yes;               # when device opened, read it
  AlwaysOpen = yes;
  RemovableMedia = yes;
  RandomAccess = no;
  Spool Directory = /mnt/tmp/bacula/tape
  Maximum Job Spool Size = 5G
#  Maximum Block Size = 262144
#  Minimum Block Size = 262144
#  Volume Poll Interval = 5 minutes
#  Close on Poll = Yes
#  Offline On Unmount = no
  LabelMedia = Yes
  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"

#  Maximum blocksize = 512K

}
