Public Adapters

Pairs of public adapters connect each cluster node to the public network. Public adapters are organized into IP multipathing groups. Each adapter in a multipathing group can be active or can be configured as a standby interface that is inactive unless a failover occurs.

You must select the type of IP supported by your public adapter: IPV4, IPV6, or both. If you select IPv4, a test address field is required. The in.mpathd multipathing daemon uses a test IP address to detect failures and repairs. If a fault is detected on one of the adapters by this daemon, a failover occurs. All network access fails over from the faulted adapter to another adapter in the multipathing group.

Multipathing groups provide the foundation for logical hostname and shared address resources. The same multipathing group on a node can host any number of logical hostname or shared address resources. You can also use multipathing groups to monitor public network connectivity of cluster nodes.
