Error message is: addnp requires 3 arguments, help says:
- --addnp=TARGET_IQN TPGT IP:PORT

I assumed TPGT refers to the portal group, which the yast interface
listed as 1 - adding a 1 to the commandline between iqn and IP worked.

Worked for me - and with yast on the initiator side the target is
discovered and the message that one should use multipathing appears as
it did with SLES11.

YaST didn't complain when I started the LIO target module afterwards.

I think you saved me hours of pointless searching for a solution.

Is there some documentation on this somewhere? lio_node --help brings
up a log of options, but there is no manual page for it.

Still unresolved for me is the authentication piece. Connecting to the
target without authentication works, but I didn't manage to connect
when authentication is turned on.

Kind regards,

Björn
