Currently, your host is connected through a single initiator, the 'Default' interface (Iface Name: default), to 2 targets: tgta and tgtb
I see what you mean, but the "Iface Name" is somewhat irritating here, it does not mean that the wrong interface (ovirtmgmt) is used. If you have a look at "Iface IPaddress" for both you can see that the correct, dedicated interfaces are used: Iface IPaddress: 10.0.131.122 (iSCSIA network) Iface IPaddress: 10.0.132.122 (iSCSIB network)
(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.
Please see above. The storage servers iSCSI-addresses aren't even reachable from the ovirtmgmt net, they are in completely isolated networks.
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.
This is exactly what I did, expect that I had to add the iSCSI-storage first, otherwise the "iSCSI Multipathing" tab does not appear in the data center section. I configured an iSCSI-Bond and the problem seems to be that it leads to conflicting iSCSI-settings on the host. The host uses the very same interface twice only with different "IFace Name": iSCSIA: Iface Name: default Iface Transport: tcp Iface Initiatorname: iqn.1994-05.com.redhat:cda91b279ac5 Iface IPaddress: 10.0.131.122 Iface Name: enp9s0f0 Iface Transport: tcp Iface Initiatorname: iqn.1994-05.com.redhat:cda91b279ac5 Iface IPaddress: 10.0.131.122 iSCSIB: Iface Name: default Iface Transport: tcp Iface Initiatorname: iqn.1994-05.com.redhat:cda91b279ac5 Iface IPaddress: 10.0.132.122 Iface Name: enp9s0f1 Iface Transport: tcp Iface Initiatorname: iqn.1994-05.com.redhat:cda91b279ac5 Iface IPaddress: 10.0.132.122 I guess this is the reason why the host has problems to attach the storage domain, it toggles all storage domains on and off all the time. Thank you, Uwe
