Storage Foundation and High Availability Solutions 7.4.2 Solutions Guide - Windows

To clone the service group configuration from the primary site to the secondary site

1. At the primary site, verify that you have brought the application service group online.
2. Start the Solutions Configuration Center from the Apps menu on the Start screen.

   Expand the Solutions for Solutions for Additional Applications tab.

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

3. In the Welcome panel, click Next and continue through the wizard, providing the requested information for the primary site system, the service group, the secondary site system, and the replication method.

   If you selected the Volume Replicator replication method, the wizard proceeds to the storage cloning task and notifies you if it detects that the storage is identical. Click Next until you reach the Service Group Analysis panel.

   If you selected an array-based replication method (EMC SRDF, HTC, or GCO only), the temporary storage is no longer needed once the application is installed and the wizard confirms whether or not to delete it.

4. (Array-based replication method only) In the Temporary Storage Deletion panel, confirm whether or not to delete the cloned storage:

   • If the application is already installed on the required nodes, leave Delete cloned storage checked and click Next. When the wizard prompts you to confirm deleting the shared storage, click Yes.

   • If you want to delete the cloned storage manually later, uncheck Delete cloned storage and click Next.

5. (Array-based replication method only) If you selected to delete the cloned storage, the wizard shows the progress of the tasks in the Implementation panel. If the storage deletion fails, the wizard will show a failure summary page. Otherwise, when it shows the tasks are complete, click Next.
6. Review the following information displayed in the Service Group Analysis panel and click Next to continue with service group cloning.

   Service Group Name	Displays the list of application-related service groups present on the cluster at the primary site.
   Service Group Details on the Primary Cluster	Displays the resource attributes for the service group at the primary site. The NIC resource consists of the MAC address. The IP resource consists of the IP address and subnet mask.
   Service Group Details on the Secondary Cluster	Displays a message to indicate whether the service group or the corresponding attributes have been configured at the secondary site.

7. In the Service Group Cloning panel, specify the requested system information for the secondary site.

   Service Group Name	Depending on the application service group already created at the primary site, and subsequently selected on the Service Group Selection page, the wizard displays the names of the service groups that will be cloned at the secondary site.
   Available Systems	Displays a list of available systems on the secondary cluster that are not yet selected for service group cloning. Select any additional secondary systems on which you want the wizard to clone the application service group configuration. Either double-click on the system name or use the > option to move the hosts into the Selected Systems pane. Note: If you want to add systems to a service group after you finish cloning the service group configuration with the DR wizard, you cannot do so by running the DR wizard again. Instead, run the VCS configuration wizard and edit the system list of the existing service group.
   Selected Systems	Displays the list of selected systems. The secondary system that you selected earlier in the wizard is listed by default.

   Click Next.

8. In the Service Group Attribute Selection panel, complete the requested information to create the required resources on the secondary site. The panel also displays the service group resource name and the attribute information at the primary site.

   Resource Name	Displays the list of resources that exist on the primary cluster.
   Attribute Name	Displays the attribute name associated with each of the resources displayed in the Resource Name column. If you need to edit additional attributes that are not shown, you must edit them manually on the secondary site service group once service group cloning is complete.
   Primary Cluster	Displays the primary attribute values for each of the displayed attributes.
   Secondary Cluster	For an IPv4 network, the default is the same as the primary cluster; the same virtual IP address can be used if both sites exist on the same network segment. You can specify different attributes depending on your environment. For IPv6, select the network from the dropdown list. An IP address will be generated from the network. For the MACAddress attribute select the appropriate public NIC from the drop-down list. For IPv6 available NICs are those belonging to the selected IPv6 network.

   Click Next.

9. In the Service Group Summary, review the attribute information that will be cloned on to the secondary cluster. Click Back to change any of the secondary service group attributes. Otherwise, click Next to proceed with cloning the service group configuration on the secondary site.
10. In the Implementation panel, wait until all the tasks are completed.The progress bar indicates the status of the tasks. Successful tasks are marked with a check symbol. If some task could not be completed successfully, the task is marked with an (x) symbol. The Information column displays details about the reasons for task failure. Click Next.
11. If the cloning failed, review the troubleshooting information. Otherwise, click Next to continue with the replication and GCO configuration, or with GCO only, depending on which option you selected. Optionally, you can exit the wizard at this point and launch the wizard again later. When you launch the wizard again, continue through the wizard, specifying the primary site system, the service group, the secondary site system, and the replication method. Click Next to continue to the replication and/or GCO configuration task.
