NOTE: In release 2.4 of the HP VAN SDN Controller, High Availability (HA) and the associated Teaming and Regional operation are provided as a technical preview. For more information, see the release notes provided for controller version 2.4. | |
The default configuration of the SDN Controller is the system’s eth0 interface. When a controller team is formed via REST with the team IP Address, an alias in the controller elected as leader will be configured automatically by the system and will attach to the eth0 interface by default. If the SDN Controller has multiple Ethernet interfaces a different interface can be required for the team IP Address. In this case the configuration /etc/sdn/admin/options might be changed using vim or emacs to reflect the desired configuration.
sdncontroller:/opt/sdn/admin# cat options
export ADMIN_OPTS="-Dcom.hp.sdn.admin.interface=eth0"Once the change has been made, the SDNA service must be restarted as shown with the following command.
This change must be made for every active controller within the team and does not require that the team to be deleted via REST.
To view the team IP Address designation from the SDN Controller console or SSH session, use ifconfig.
