Both nodes require Ethernet cards (NICs) that enable the private network. If both Node A and Node B have Ethernet cards installed, you can ignore this step.
For high availability, use two separate NICs on each node. The two NICs provide redundancy for heartbeating.
To install and configure Ethernet cards for private network
# hastop -local
Install the Ethernet card on Node A.
If you want to use aggregated interface to set up private network, configure aggregated interface.
Install the Ethernet card on Node B.
If you want to use aggregated interface to set up private network, configure aggregated interface.
Make the two Ethernet cable connections from Node A to Node B for the private networks.
