You might require Sun Cluster to make highly available an application other than NFS or DNS that is integrated with the Solaris Service Management Facility (SMF). To ensure that Sun Cluster can restart or fail over the application correctly after a failure, you must disable SMF service instances for the application as follows:
For any application other than NFS or DNS, disable the SMF service instance on all potential primary nodes for the Sun Cluster resource that represents the application.
If multiple instances of the application share any component that you require Sun Cluster to monitor, disable all service instances of the application. Examples of such components are daemons, file systems, and devices.
If you do not disable the SMF service instances of the application, both the Solaris SMF and Sun Cluster might attempt to control the startup and shutdown of the application. As a result, the behavior of the application might become unpredictable.
