   Otherwise, launch the wizard and proceed to the GCO Setup panel by following these steps sequentially:

   • Start the DR Configuration Wizard from the Solutions Configuration Center by clicking Start > All Programs > Veritas > Veritas Cluster Server > Solutions Configuration Center or, on Windows 2012 operating systems, from the Apps menu.

   • Expand the Solutions for Solutions for Additional Applications tab.

   • In the Welcome panel, click Next and continue through the wizard, providing the requested information.

   • In the Replication Methods panel, click Configure Global Cluster Option (GCO) only. Click Next and continue to the GCO Setup panel.

2. In the GCO Setup panel, review the requirements. If you have met the requirements, click Next.
3. In the Global Cluster Settings panel specify the heartbeat information for the wide-area connector resource. You must specify this information for the primary and the secondary cluster. Any existing WAC resource information can be reused. If you are adding a DR site to an existing DR configuration, GCO is already configured at the primary site, so the primary site fields are dimmed.

   Use existing settings	Allows you to use a WAC resource that already exists at either the primary or secondary site. Click Primary or Secondary, depending on the site at which the WAC resource already exists.
   Resource Name	Select the existing WAC resource name from the resource name list box.
   Create new settings	Select the appropriate site, primary or secondary, for which you want to create a new WAC resource.
   IP Address	For IPv4, enter a virtual IP for the WAC resource. For IPv6, select the network from the dropdown list. An IP address will be generated.
   Subnet Mask or Prefix	For IPv4, enter the subnet mask for the system at the primary site and the secondary site. For IPv6, enter the prefix.
   Public NIC	Select the public NIC for each system from the drop-down list for the system at the primary and secondary site.
   Start GCO after configuration	Select this check box to bring the cluster service group online and start GCO automatically after the wizard completes the necessary configurations. Otherwise, you must bring the service group online and start GCO manually, after the wizard completes. Once GCO is configured and running, deselecting the checkbox does not stop GCO.

4. In the Settings Summary panel, review the displayed information.

   If you want to change any of the parameters specified, click Back.

   Otherwise, click Next.

5.

An (x) symbol indicates a task that could not be completed successfully. The Information column shows details about the reasons for task failure. Click Next.
6. In the Finish panel, review the displayed information. If a task did not complete successfully, the panel displays an error message, which will provide some insight into the cause for failure. Click Finish to exit the wizard.
