Hi Nicolas,

The vdsm log doesn't have the correlating time span of when I estimate the error occurred on the engine log.
Please check if it was rotated and send the relevant log (I see a discovery error on 2014-10-22 09:11:36 ).

I'd like to better understand what you did.
The flow when adding as iSCSI domain is first discover targets by pressing the 'Discover' button, and only then pressing the 'log in' button.
As far as I can see in the engine log, you already hit the wall by discovering, not even getting to log in. After this button is hit is also when you should see the LUNs, but you say you hit the login button and that it functions well, so I don't exactly understand the flow.
