Found the issue the documentation for #mtx is wrong.
The device is NOT called /dev/changer* it's /dev/sch*.
And btw the kernel module for it is "ch" but it was already loaded by udev.

Soo why does the /dev/changer device for this IBM TS3100 not show up?
What did I forget to install?

Writing a VTL Linux Kernel Module for fun [?]
Anyways, realized my SysFS approach was misguided, and migrating to ConfigFS for creating/destroying kernel objects like SCSI Hosts.
Man oh man is there a lot of boiler plate to get ConfigFS up and running, but I think that I've sticklebricked it together correctly at last.
You can create SCSI hosts by making dirs in/config/cvtl/hostswhich have theidandenabledattributes (the full SCSI Host object to come soon). If you write a '1' to your host'senabledfile it will register it with the SCSI Midlayer, which you can see near the end as it creates SysFS objects in/sys/class/scsi_host/hostX
So when you want to make a virtual tape library you can just make some directories, andechothe values you want to their underlying files and then enable the host with the targets and LUNs you want. Seems like a very friendly interface.
