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 _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
