Configuring WAN redundancy with no Core HA
1. Configure local interfaces on the Edge. The interfaces are used to connect to the Core.
2. Configure preferred interfaces for connecting to the Edge on the Core under Configure > Manage: Edges. Select Show Preferred Interfaces for Edge Connections, and then add an interface. On first connection, the Core sends all the preferred interface information to the Edge. The Edge uses this information along with configured local interfaces to connect on each link (local-interface and preferred-interface pair) until a successful connection is formed. The Edge tries each connection three times (and waits 3 seconds before the next try) before it moves on to the next; that is, if the first link fails, the next link is tried in nine seconds. After the Core and the Edge have established a successful alternative link, the Edge updates its Rdisk configuration with the change, so that the configuration is on the same link as the management channel between Core and Edge.
3. Remove the local interface for WAN redundancy on Edge:
– From the Edge Management Console, choose Storage > Storage Edge Configuration.
– Open the interface you want to remove.
– Remove the interface.
4. Remove preferred interfaces for WAN redundancy on the Core:
– From the Core Management Console, choose Configure > Manage: Edges.
– Select Show Preferred Interfaces for Edge Connections.
– Open the interface you want to remove.
– Delete the interface.
Any change in the preferred interfaces on the Core is communicated to the Edge and the connection is updated as needed.
