Administering global clusters

Creating a global cluster environment requires the following conditions:

• The ClusterService group for all clusters must be properly configured for GCO operations. The csgnic, gcoip, and wac resources must be able to come online.
• The service group intended to serve as the global group has the same unique name on all clusters that participate in the global environment.
• The clusters all have different, unique names.
• 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.
• All clusters must either be configured in secure mode or not configured in secure mode. Mixing of modes is not supported.

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.

Use the Cluster:Summary, Cluster:Resources, or Group:Summary views to administer a global cluster.
