The global clustering wizard completes the following tasks:
Validates the ability of the current configuration to support a global cluster environment.
Creates the components that enable the separate clusters, each of which contains a different set of GAB memberships, to connect and operate as a single unit.
Creates the ClusterService group, or updates an existing ClusterService group.
Run the global clustering configuration wizard on each of the clusters; you must have the global clustering license in place on each node in the cluster.
To modify the ClusterService group for global clusters using the global clustering wizard
On the primary cluster, start the GCO Configuration wizard:
# /opt/VRTSvcs/bin/gcoconfig
The wizard discovers the NIC devices on the local system and prompts you to enter the device to be used for the global cluster. Specify the name of the device and press Enter.
If you do not have NIC resources in your configuration, the wizard asks you whether the specified NIC will be the public NIC used by all the systems. Enter y if it is the public NIC; otherwise enter n. If you entered n, the wizard prompts you to enter the names of NICs on all systems.
If you do not have IP resources in your configuration, the wizard prompts you for the netmask associated with the virtual IP. The wizard detects the netmask; you can accept the suggested value or enter another one.
The wizard starts running commands to create or update the ClusterService group. Various messages indicate the status of these commands. After running these commands, the wizard brings the ClusterService group online.
