Currently, your host is connected through a single initiator, the 'Default' interface (Iface Name: default), to 2 targets: tgta and tgtb (Target: iqn.2005-10.org.freenas.ctl:tgta and Target: iqn.2005-10.org.freenas.ctl:tgtb). Hence, each LUN is exposed from the storage server via 2 paths. Since the connection to the storage is done via the 'Default' interface and not via the 2 iSCSI networks you've configured, currently, the iSCSI bond is not operational.
For the iSCSI bond to be operational, you'll have to do the following: - Create 2 networks in RHEVM under the relevant cluster (not sure if you've already did it) - iSCSI1 and iSCSI2 . Configure both networks to be non-required networks for the cluster (should be also non-VM networks). - Attach the networks to the host's 2 interfaces using hosts Setup-networks. - Create a new iSCSI bond / modify the bond you've created and pick the 2 newly created networks along with all storage targets. Make sure that the Default network is not part of the bond (usually, the Default network is the management one - 'ovirtmgmt'). - Put the host in maintenance and re-activate it so the iSCSI sessions will be refreshed with the new connection specifications. Please let me know if it works for you.
