Here is my config:
I have an Exabyte224 with 2 LTO2 drives.
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 = 2G
LabelMedia = Yes
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}
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 = 2G
LabelMedia = Yes
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}
