Veritas Cluster Server (VCS) agents provide high availability to resources within a cluster environment. Resources are hardware or software entities that make up the application. A few examples of resources include disk groups and file systems, network interface cards (NIC), IP addresses, and applications are a few examples of resources. Each type of resource requires an agent.

The agent acts as an intermediary between VCS and the resources it manages, typically by bringing them online, monitoring their state, or taking them offline.

For more information on VCS agents, see:

VCS agents are classified as follows:

Bundled agents — Bundled agents are Veritas Cluster Server processes that manage resources of predefined resource types according to commands received from the VCS engine, the High Availability Daemon (HAD). They include agents for Disk, Mount, IP, and various other resource types. Bundled agents are packaged and installed along with VCS.

For more information on Bundled agents, see:

Veritas Cluster Server Bundled Agents Reference Guide

Enterprise agents — Enterprise agents control third party enterprise applications, namely, Oracle, Sybase, and DB2. These enterprise agents are packaged along with VCS.

For more information on VCS enterprise agents, see:

VCS Agent for Oracle Installation and Configuration Guide

VCS Agent for Sybase Installation and Configuration Guide

VCS Agent for DB2 Installation and Configuration Guide

You can download the enterprise agents that are shipped separately, from the Symantec Operations Readiness Tools (SORT) website, at

Agent Pack agents — Agent Pack agents are developed by Symantec for enterprise applications, databases, and replication solutions. They are part of the quarterly Agent Pack release. These agents are also available on the SORT website.

For more information on VCS agents shipped with the Agent Pack release, see:

Veritas High Availability Agent Pack Getting Started Guide

Custom agents — Custom agents are developed by third parties. Typically, custom agents are developed because the user requires control of an application that current agents do not support.

For more information on developing custom VCS agents, see:

Veritas Cluster Server Agent Developer's Guide

VCS documentation for other releases and platforms can be found on the SORT website.
