Description

This procedure is used to determine which motherboard is at fault for a 2-node switchless cluster that uses the on-board e0a/e0b ports when one or both of the cluster ports are flapping. For the purposes of the examples, the nodes will be Node_01 and Node_02.

Note that for nodes that do not use e0a/e0b for their cluster ports, the following procedure will need to be modified accordingly to refer to the correct in-use cluster ports on the respective nodes and available test ports as shown in the provided table.
