The information in the VCS configuration is passed by the engine to the FileOnOff agent when the agent starts up on a node in the cluster. The information passed to the agent includes: the names of the resources of the type FileOnOff configured on the system, the corresponding resource attributes, and the values of the attributes for all of the resources of that type. It also sends all the attribute and their repective value details to the agent.

Thereafter, to bring the resource online, for example,VCS can provide the agent with the name of the entry point (online) and the name of the resource (temp_file01). The agent then calls the entry point and provides the resource name and values for the attributes in the ArgList to the entry point. The entry point performs its tasks.
