Ah, I understand. This is probably related to the fact that you aren't
creating a storage domain, only the storage connection. This should work
correctly, but I guess that either the GUI or the backend aren't
completely prepared for this. I'm checking.

For a direct LUN disk all these values are ready only. Why do you need
to change them?

I think this is a bug, and I didn't find any way to workaround it other
than creating the LUN using the GUI instead of the RESTAPI. I opened the
following BZ to track it:
