About global clusters

The process of creating a global cluster environment involves creating a common service group for specified clusters, making sure all the service groups are capable of being brought online in the specified clusters, connecting the standalone clusters, and converting the service group that is common to all the clusters to a global service group. Use the console to add and delete remote clusters, create global service groups, and manage cluster heartbeats.

Creating a global cluster environment requires the following conditions:

• All service groups are properly configured and able to come online.
• The service group that will serve as the global group has the same unique name across all applicable clusters.
• The clusters must use the same version of VCS.
• The clusters must use the same operating system.
• The clusters are standalone and do not already belong to a global cluster environment.

Through the Java Console, you can simulate the process of generating and clearing global cluster faults in an offline state. Use VCS Simulator to complete these operations.

For remote cluster operations, you must configure a VCS user with the same name and privileges in each cluster.

See User privileges in global clusters.

  Note   Cluster Manager (Java Console) provides disabled individuals access to and use of information and data that is comparable to the access and use provided to non-disabled individuals. See Accessibility and VCS.
