Symptoms

The server is getting several errors. For example, an error while adding the Oracle VM server to a serverpool .

"OVMAPI_4004E Sync command failed on server: Command: configure_server_for_cluster, Server error: org.apache.xmlrpc.XmlRpcException: <type 'exceptions.Exception'>:Unable to online cluster" 

The server bonding interfaces are in Active/Active mode (802.3ad) but the interfaces are unable to successful negotiate the LACP with the network switch.

The following command show that each interface is in a different aggregate ID which means that they haven't successful negotiate with the network switch:
