A Solaris cluster reconfiguration can be triggered by a variety of events such as a change in the membership of cluster
(one node that leaves/joines the cluster is a good example of this type) or also by a change in the quorum device configuration (such as Adding/Changing/Removing QD)
All those events mentioned above imply either a change in the configuration or the execution of operations that might be unaffordable at a given time
(such as bringing one node down).
Nevertheless there might be the need to force a Solaris Cluster reconfiguration for testing purposes.
For instance one might want to test the ability to send snmp trap of Solaris Cluster after having configured it.
Forcing a cluster reconfiguration is a good method to generate an event that triggers the sending of a snmp trap by Solaris Cluster.
Such a cluster reconfiguration does not interfere with normal Solaris Cluster activities , it is harmless and doesn't need any change in cluster
