basically, you should upgrade your DC to 3.4, and then upgrade the clusters you desire also to 3.4.
Well, that seems to have worked, except I had to raise the cluster level first, then the DC level.
Now, I can see the iSCSI multipath tab has appeared. But I confirm what I wrote below :
I saw that multipathing is talked here : http://www.ovirt.org/Feature/iSCSI-Multipath
Add an iSCSI Storage to the Data Center Make sure the Data Center contains networks. Go to the Data Center main tab and choose the specific Data Center At the sub tab choose "iSCSI Bond" Press the "new" button to add a new iSCSI Bond Configure the networks you want to add to the new iSCSI Bond.
Anyway, I'm not sure to understand the point of this wiki page and this implementation : it looks like a much higher level of multipathing over virtual networks, and not at all what I'm talking about above...?
I am actually trying to know whether bonding interfaces (at low level) for the iSCSI network is a bad thing, as was told by my storage provider?

Hi Nicolas, I think the naming of the managed iscsi multipathing feature a "bond" might be a bit confusing. It's not an ethernet/nic bond, but a way to group networks and targets together, so it's not "bonding interfaces" Behind the scenes what it does is creates iscsi ifaces(/var/lib/iscsi/ifaces) and changes the way the iscsiadm calls are constructed to use those ifaces (instead of the default) to connect and login to the targets Hope that helps. -John
