Hello Doug,
It seems that the tape device configuration is missing the "DriveIndex"
value:
Device {
Name = "LTO-7"
Description = "LTO-7"
MediaType = "LTO-7"
DeviceType = "Tape"
DriveIndex = 0 <---- if this is the only drive in the tape library,
this value should be 0
ArchiveDevice = "/dev/nst0"
AutomaticMount = yes
Autochanger = yes
RemovableMedia = yes;
RandomAccess = no;
AlwaysOpen = yes;
ChangerDevice = "/dev/sg3"
ChangerCommand = "/opt/bacula/scripts/mtx-changer %c %o %S %a %d"
AlertCommand = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
MaximumFileSize = 100G
LabelType = "Bacula"
LabelMedia = yes
}
Then, you need to restart the SD.
Best,
Ana
