Thanks for the link! I've done some more searching online and I found some documentation about enabling the following option: options lin_tape alternate_pathing=1 So I created a /etc/modprobe.d/lin_tape.conf file and added this option to it, along with the persistent naming option: options lin_tape persistent_n_device=1 I also created the /etc/udev/rules.d/98-lin_tape.rules file with all the drives in it. I stopped and unloaded lin_tape, reloaded the rules with udevadm control --reload-rules and loaded and started lin_tape. I was expecting to see the devices created, but I still can't find a /dev/lin_tape/by-id directory. I don't have to create this directory manually, do I? Thanks again for your help!

I would follow https://www.ibm.com/docs/en/ts4300-tape-library?topic=tape-taking-devices-offline-completing-maintenance to completely stop lintaped as it should remove all IBMtape/IBMchanger and then proceed with removal of generic tape devices lsscsi and find the H:B:T:L for each Tape Device. Then, for each H:B:T:L do: echo 1 > /sys/bus/scsi/devices/H:B:T:L/delete Reconfigure control paths in library (, rescan_scsi just to make sure) and start lintaped.

The library I defined contains 6 drive and I selected all drives as control path. This however creates six /dev/IBMchanger devices. So before I correct my mistake and update the library definition, I like to remove /dev/IBMchanger1 to 5 first. What is the proper way to remove these library devices from a Linux host? Thanks for any help in advance!
