About the Hitachi TrueCopy Agent

The VCS enterprise agent for Hitachi TrueCopy monitors and manages the state of replicated devices attached to local hosts. The agent ensures that the system on which the TrueCopy resource is online has safe and exclusive access to the configured devices.

The agent can be used in single VCS replicated data clusters and multi-cluster environments set up using the VCS Global Cluster Option.

The agent supports TrueCopy in all fence levels that are supported on a particular array.

When replicating between Lightning arrays, the agent supports the following fence levels: data, never, and async.

When replicating between Thunder arrays, the agent supports the following fence levels: data and never.
