VCS Agents: An Overview

Each VCS agent is a program that manages resources of a particular type, such as a disk group or an IP address, within a cluster environment. Each resource type requires an agent. The agent acts as an intermediary between VCS and the resource it manages, typically by bringing it online, monitoring its state, or taking it offline.

Agents packaged with VCS are referred to as bundled agents. Examples of bundled agents include Share, IP (Internet Protocol), and NIC (network interface card) agents. For more information on VCS bundled agents, including their attributes and modes of operation, see the

Agents packaged separately for use with VCS are referred to as enterprise agents. They include agents for Informix, Sybase, Oracle, and others. Contact your VERITAS sales representative for information on how to purchase these agents for your configuration.

For information on installing and configuring VCS, see the VERITAS Cluster Server Installation Guide.
