I’m not sure how to fix it. Sometimes it just gets wedged into this state where
even running mtx status will fail with Inquiry Command failed. Then a reboot

I wanted to use a package but could not find any that had both psql and openssl
options.

Yes that’s what I’m doing with the tape library device. The second tape drive
is commented out.

Yeah all those errors happened when it was wedged. I didn’t realize it. After a
reboot they work.

Thanks for your efforts documenting all this. I have read most if not all of it.
