Changing the configuration of communication interfaces

As a system administrator, you may need to perform several different tasks relating to cluster network interfaces.

Adding PowerHA SystemMirror network interfaces
You can add a network interface to an active cluster dynamically. You do not need to stop and restart cluster services for the network interface to become part of the cluster.
Changing network interface attributes
You cannot change the attributes of a network interface dynamically. You must stop and restart cluster services for the changes to take effect in the configuration.
Removing a network interface from a cluster node
You can remove a PowerHA® SystemMirror® network interface from an active cluster dynamically; you do not need to stop and restart cluster services.
