Hi Elad,

thank you very much for clearing things up.

Initiator/iface 'a' tries to connect target 'b' and vice versa. As 'a' and 'b' are in completely separate networks this can never work as long as there is no routing between the networks.

So it seems the iSCSI-bonding feature is not useful for my setup. I still wonder how and where this feature is supposed to be used?

thank you,
Uwe

Thanks.

You're getting an iSCSI connection timeout [1], [2]. It means the host
cannot connect to the targets from iface: enp9s0f1 nor iface: enp9s0f0.

This causes the host to loose its connection to the storage and also,
the connection to the engine becomes inactive. Therefore, the host
changes its status to Non-responsive [3] and since it's the SPM, the
whole DC, with all its storage domains become inactive.
