I'm using Ubuntu 18.04.1 with Bacula 9.0.6 from the main repo. I'd like to enable the above alerts from the sample bacula-sd.conf but can't because my system is assigning random device names after each reboot so that /dev/nst0, /dev/nst1, etc. can be any /dev/sg* number. I looked into creating a udev rule for the drives but there's no output from the control device that can be uniquely identified (DEVPATH can't be used in a udev rule I've found out): *> udevadm info -n /dev/sg1 --query=allP: /devices/pci0000:00/0000:00:02.0/0000:05:00.0/0000:06:01.0/0000:09:00.0/0000:0a:01.0/0000:0b:00.0/host2/rport-2:0-0/target2:0:0/2:0:0:0/scsi_generic/sg1N: sg1E: DEVNAME=/dev/sg1E: DEVPATH=/devices/pci0000:00/0000:00:02.0/0000:05:00.0/0000:06:01.0/0000:09:00.0/0000:0a:01.0/0000:0b:00.0/host2/rport-2:0-0/target2:0:0/2:0:0:0/scsi_generic/sg1E: MAJOR=21E: MINOR=1E: SUBSYSTEM=scsi_generic* Is there another way do make this work? There's a more recent firmware for my tape library, a Dell ML6000, that I've held off installing. Do you think a new firmware might allow the sg driver to provide more output? Should I quit worrying about getting alerts working since the tape library itself has a similar capability or is it important for Bacula to function correctly? Thanks, Nate
