VCS agents for VVR
|
You can use the following VCS agents for VVR in a VCS global cluster setup:
-
RVG agent
The RVG agent manages the Replicated Volume Group (RVG). Specifically, it brings the RVG online, monitors read-write access to the RVG, and takes the RVG offline. Use this agent when using VVR for replication.
-
RVGPrimary agent
The RVGPrimary agent attempts to migrate or take over a Secondary site to a Primary site following an application failover. The agent has no actions associated with the offline and monitor routines.
-
RVGShared agent
The RVGShared agent monitors the RVG in a shared environment. This is a parallel resource. The RVGShared agent enables you to configure parallel applications to use an RVG in a cluster. The RVGShared agent monitors the RVG in a shared disk group environment.
-
RVGSharedPri agent
The RVGSharedPri agent enables migration and takeover of a VVR replicated data set in parallel groups in a VCS environment. Bringing a resource of type RVGSharedPri online causes the RVG on the local host to become a primary if it is not already.
-
RVGLogowner agent
The RVGLogowner agent assigns and unassigns a node as the logowner in the CVM cluster; this is a failover resource. The RVGLogowner agent assigns or unassigns a node as a logowner in the cluster. In a shared disk group environment, only one node, that is, the logowner, can replicate data to the Secondary.
-
RVGSnapshot agent
The RVGSnapshot agent, used in fire drill service groups, takes space-optimized snapshots so that
applications can be mounted at secondary sites during a fire drill operation.
See the Veritas InfoScale™ Replication Administrator's Guide for more information.
In a CVM environment, the RVGShared agent, RVGSharedPri agent, RVGLogOwner agent, and RVGSnapshot agent are supported. For more information, see the Cluster Server Bundled Agents Reference Guide.

VCS agents for third-party replication technologies
|
VCS provides agents for other third-party array-based or application-based replication solutions. These agents are available in the High Availability Agent Pack software.
See the High Availability Agent Pack Getting Started Guide for a list of replication technologies that VCS supports.
