Configuring a global cluster for environment with SFCFSHA and Veritas Volume Replicator requires the coordination of many component setup tasks. The tasks listed below are guidelines.
Before configuring two clusters for global clustering, you must verify that:
You have the correct installation options enabled for SFCFSHA, whether you are using keyless licensing or installing keys manually. You must have the GCO option for a global cluster and VVR enabled.
Review SFCFSHA requirements and licensing information.
Both clusters have SFCFSHA software installed and configured.
Note: |
You can install and configure both clusters at the same time, or you can configure the second cluster at a later time than the first. |
You can use this guide to install and configure SFCFSHA on each cluster. For details for configuring a global cluster environment and replication between the the clusters using VVR:
See the Veritas Storage Foundation and High Availability Solutions Disaster Recovery Implementation Guide.
With two clusters installed and configured , you are ready to configure a global cluster environment using VVR. You must perform the following tasks to modify both cluster configurations to support replication in the global cluster environment.

Once the global clusters and replication with VVR are configured, the following replication use cases are supported for it:
Migration of the role of the primary site to the remote site
Takeover of the primary site role by the secondary site
Migrate the role of primary site to the secondary site
Migrate the role of new primary site back to the original primary site
Take over after an outage
Resynchronize after an outage
Update the rlink to reflect changes
