Agents are processes that manage predefined resource types. When an agent is started, it obtains configuration information from the Veritas Cluster Server (VCS). It then periodically monitors the resources and updates VCS with the resource status.
VCS bundled agents are part of VCS and are installed when VCS is installed. The cluster functionality agents are add-on resources to VCS for the Veritas File System and Veritas Volume Manager (VxVM). Cluster functionality agents and resource types are part of the VRTScavf package and are configured when you run thecfscluster config command.
See the Veritas Cluster Server Bundled Agents Reference Guide.
