Configuring disaster recovery with the DR wizard

Note:

The DR wizard cannot be used if you are setting up DR in a non-shared storage environment.

This procedure describes how to configure disaster recovery using the wizard.

To start configuring disaster recovery with the DR wizard

  1. 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.
  2. Click Disaster Recovery Configuration > Configure Disaster Recovery > Disaster Recovery Configuration Wizard.

    Note:

    By design, the DR wizard requires specific settings for the Lanman attributes on the primary and secondary sites. Before beginning the DR configuration, the wizard checks for these values, and if they are not set as required, the wizard will automatically proceed with setting these values, both at the primary and secondary sites.

  3. In the Welcome panel, review the prerequisites to ensure that they are met and click Next.
  4. In the System Selection panel, provide information in the System Name field:

    Enter the IP address or Fully Qualified Host Name (FQHN) of the primary system where the application is online.

    If you have launched the wizard on the system where the application is online at the primary site, you can also specify localhost to connect to the system.

    Click Next.

  5. In the Service Group Selection panel, select the service group that you want to clone to the secondary site.

    For a hardware replication environment, you can choose to clone only the parent service group by not selecting the dependent service group. Only online and local dependencies are supported, in soft, firm, or hard configurations. The wizard can configure only one level of dependency.

    In a Volume Replicator environment, the DR wizard does not support configuring DR for a service group that has a child. If you select a service group that has a child, you will receive an error message when you select the Volume Replicator replication method later in the wizard.

    The panel lists only service groups that contain a MountV resource.

    Click Next.

  6. In the Secondary System Selection panel, enter the Fully Qualified Host Name (FQHN) or the IP address of the secondary system for which you want to configure disaster recovery.

    Click Next.

  7. In the Replication Options panel, select the replication method. Although you must select the replication method now, configuring replication and the global cluster option is done later, after service group cloning.

    Configure Volume Replicator (Volume Replicator) and the Global Cluster Option (GCO)

    Select this option if you want to configure Volume Replicator replication.

    Select this option even if you plan to configure Volume Replicator replication or the GCO option manually. This option is required for the wizard to configure the storage cloning correctly for a Volume Replicator environment.

    The wizard verifies each configuration task and recognizes if a task has been completed successfully.

    You cannot mix replication methods. That is, if your primary site is using array-based replication, and you select the Volume Replicator option, the wizard will warn you that you cannot use Volume Replicator replication for the disaster recovery site.

    Configure EMC SRDF and the Global Cluster Option (GCO)

    Select this replication option if you want to configure the settings for the VCS EMC SRDF agent. All disks used for the service group on the primary site must belong to an EMC SRDF array.

    Select this option even if you plan to configure EMC SRDF replication or the GCO option manually. The wizard verifies each configuration task and recognizes if a task has been completed successfully.

    Configure Hitachi TrueCopy and the Global Cluster Option (GCO)

    Select this replication option if you want to configure the settings for the VCS Hitachi TrueCopy agent. All disks used for the service group on the primary site must belong to a Hitachi TrueCopy array.

    Select this option even if you configure GCO manually. The wizard verifies each configuration task and recognizes if a task has been completed successfully.

    Configure the Global Cluster Option (GCO) only

    If you select this option, the DR wizard does not configure any replication settings. It configures the global cluster option.

    Select this option if you want to use the wizard in an array-based replication environment that is not supported by this wizard. You must configure replication manually after you finish the wizard.

    If you select the GCO only option, the DR wizard sets up the storage and service group configuration on the secondary site for an array-based hardware replication environment. Therefore, you cannot use this option to clone the storage and service group for a Volume Replicator replication environment.

    Click Next.

  8. Continue with the next DR configuration task.
