Takeover configuration with shared interfaces
You can configure two NICs, one on each node, to provide two shared interfaces to each node.
In the following configuration illustration, you use two NICs to provide the two interfaces:
If Node 1 fails, interface e0 on Node 1 stops functioning, but the secondary address on e0 on Node 2 handles the Node 1 network connection with the 230 network.
If Node 2 fails, e0 on Node 2 stops functioning, but e0 on Node 1 substitutes for the failed interface and handles the Node 2 network connection with the 230 network.
