[ovirt-users] iSCSI Multipathing -> host inactive

[Elad Ben Aharon]

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.
