Hello community, thanks so much for buildling and supporting this great
tool! I'm trying to set up a VTL to test some scenarios in my lab.
Specifically, I'm trying to replicate an environment that must use YoYotta,
a MacOS-only application that uses LTFS. I have QuadStor VTL running OK in
a Ubuntu 18.04 VM. Configured an IBM System Storage TS3100 with a IBM 3580
Ultrium8 drive and 3580u8L8 vCart. On the MacOS side, I'm using Daemon
Tools to initiate the iSCSI target, IBM SDE 2.4.12 tooling for LTFS which I
downloaded from IBM (registerwall) and the osxfuse provided by homebrew.
I'm following the steps that come with the IBM SDE download:
$ ltfs -o device_list
showed the IBM drive as expected
$ mkltfs -d 0
formatted the tape with LTFS as expected
$ mkdir /mnt
$ mkdir /mnt/ltfs
$ ltfs /mnt/ltfs -o devname=0
returned a solid block of text and then hung, and I eventually (after about
30 minutes) just killed the terminal session. Unfortunately I don't have
the error message content, thinking I could replicate it easily. However I
ran into errors trying to list the devices thereafter. I restarted both the
client, and quadstorvtl VM, re-loaded the same vcart, reconnected to the
iSCSI target, and re-ran the device_list command, which has now hung with
these messages.

Hoping that some of this makes sense to someone and I can get some advice
on how to get back to my original error, to get help on that. Right now I
can't even list devices.
Kind thanks.
