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. Elad On Tue, Aug 16, 2016 at 9:26 AM, Uwe Laverenz <uwe@laverenz.de> wrote:
Hi,

Is the iSCSI domain that supposed to be connected through the bond the
current master domain?
No, it isn't. An NFS share is the master domain.
Also, can you please provide the output of 'iscsiadm -m session -P3' ?
Yes, of course (meanwhile I have switched to 2 targets, 1 per portal). This is _without_ iSCSI-Bond:
