You can set up a primary SFCFSHA cluster for replication to a secondary SFCFSHA cluster by configuring global VCS service groups and using a replication technology. The application cluster at the secondary site can be a single node cluster. For example, you can have a two-node cluster on the primary site and a two-node or single-node cluster on the secondary site.
You can use one of the following replication technologies:
Veritas Volume Replicator (VVR), which provides host-based volume replication. Using VVR you can replicate data volumes on a shared disk group in SFCFSHA.
Supported hardware-based replication technologies. Using hardware-based replication you can replicate data from a primary array to a secondary array.
Using SFCFSHA with VVR you can run a fire drill to verify the disaster recovery capability of your configuration.
