Administering Global Clusters from Cluster Manager (Java Console)

The Global Cluster Option is required to manage global clustering for wide-area disaster recovery from the Java Console. 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:

    Checkmark  All service groups are properly configured and able to come online.

    Checkmark  The service group that will serve as the global group has the same unique name across all applicable clusters.

    Checkmark  The clusters must use the same version of VCS.

    Checkmark  The clusters must use the same operating system.

    Checkmark  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; refer to Administering VCS Simulator for information on this tool.

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 for more information.


Note   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. Refer to the appendix Accessibility and VCS for more information.
