Configuring EMC SRDF replication and global clustering

After you complete the service group configuration task in the DR wizard, you configure replication and global clustering.

The wizard helps you to configure the settings for the SRDF resource in the application service group.

Ensure that you have one static address is available per site for configuring GCO.

The wizard configures the required agent settings as well as the SYMM heartbeat. It uses defaults for optional settings.

To configure EMC SRDF replication and GCO

  1. Verify that you have brought the application service group online at the primary site.
  2. If the wizard is still open after the service group cloning task, continue with the Replication Setup panel.

    Otherwise, launch the wizard and proceed to the Replication 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 Additional Applications tab.

      Click Disaster Recovery Configuration > Configure Disaster Recovery > Disaster Recovery Configuration Wizard.

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

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

  3. In the Replication Setup panel, review the replication requirements. If you have met the requirements, click Next.

    Warning:

    Although you can continue with the wizard even if replication requirements are not met, the wizard will warn you that the configuration is not valid. If the configuration is not valid, the SRDF resource cannot come online in the service group.

  4. In the SRDF Resource Configuration panel, the wizard populates the required resource fields if replication has been configured. Otherwise, you must enter the required resource settings manually.

    Symmetrix Array ID (SID)

    Specify the array ID for the primary site and for the secondary site.

    Device Group name

    Specify the name of the Symmetrix device group that contains the disks of the disk group for the selected instance.

    Available VMDG Resources

    Select the disk groups associated with the selected application instance.

  5. If you want to configure an additional SRDF resource for the instance, click Add. Otherwise, click Next.
  6. 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

    Enter a virtual IP for the WAC resource.

    Subnet Mask

    Enter the subnet mask for the system at the primary site and the secondary site.

    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.

    Click Next.

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

    Click Back if you want to change any of the parameters specified for the replication resource settings or the global cluster settings.

    Otherwise, click Next.

  8. In the Implementation panel, wait until the wizard completes creating the replication configuration and the WAC resource required for global clustering. A check symbol indicates successful completion of a task. 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.
  9. 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.
  10. Proceed with configuring additional optional settings for the SRDF resource if desired, and then verifying the disaster recovery configuration.
