Hi ondra,
As you pointed. in your previous mail.
The iscsiadm discovered througth 10.11.8.190. It should have probed 10.10.1.1. This may be the root cause.
Victor,
If you lookup at our playbook.

It's using the host, which you will pass as host parameter to the task for iscsi discover.
As Yaniv said, can you please share your issue on our mailing list:

There are people with knowledge of iSCSI and they will help you.
