SPARC: Dynamic Reconfiguration Clustering Considerations for Public Network Interfaces

If the dynamic reconfiguration remove-board operation pertains to a board that contains an active public network interface, Oracle Solaris Cluster software rejects the operation. Oracle Solaris Cluster software also identifies the interface that would be affected by the operation. Before you remove a board with an active network interface present, switch over all traffic on that interface to another functional interface in the multipathing group by using the if_mpadm command.

Caution  -  If the remaining network adapter fails while you are performing the dynamic reconfiguration remove operation on the disabled network adapter, availability is impacted. The remaining adapter has no place to fail over for the duration of the dynamic reconfiguration operation.

See Administering the Public Network in Oracle Solaris Cluster System Administration Guide for detailed instructions about how to perform a dynamic reconfiguration remove operation on a public network interface.
