I didn’t know about sg_logs: that could be useful. One issue I have encountered and one that isn’t really addressed is that there are different paths (sg, st and nst) for a tape drive, but it isn’t always easy to know which of those device paths is associated with which drive in the changer. It is also possible that the /dev/sg* path number will be different from the st and or nst number. IBM has a lin_tape daemon that reassigns /dev/ns* to /dev/IBMtape* so that’s extra fun if you need to access this information in a repeatable fashion. Beyond the tools mentioned in the article udevadm -a can provide helpful information about a drive.
