Volume Replicator 7.4.2 Administrator's Guide - Windows

To create a replication service group

1. On the active node of the cluster at the Primary site, launch the Volume Replicator Agent Configuration Wizardfrom the Apps menu on the Start screen.
2. Review the requirements on the Welcome panel and click Next.
3. In the Wizard Options panel, click Create a new replication service group and click Next.
4. Specify the service group name and system priority list, and then click Next:

   • To remove a node from the service group's system list, click the node in the Systems in Priority Order box, and click the left arrow icon.

   • To change the priority of a node in the system list, click the node in the Systems in Priority Order box, then click the up and down arrow icons. The node at the top of the list has the highest priority.

   • To enable the service group to automatically come online on one of the systems, select the Include selected systems in the service group's AutoStartList attribute check box.

     For information about the AutoStartList attribute, see the Cluster Server Administrator's Guide.

5. A message appears, indicating that the configuration will change from Read Only to Read/Write. Click Yes to continue.

   • Select Configure RVGPrimary resource for selected RVG.

     This resource is required when you want to configure your setup to automatically enable takeover in case of a failure of the Primary cluster. The RVGPrimary resource is created in the application service group and replaces the VMDg resource.

   • Select the replicated volume group for which you want to configure the RVG Primary resource.

   • Click Next.

   You can create the RVGPrimary resource only while creating a new RVG resource and not when modifying an existing RVG resource. For an existing RVG resource, you can use VCS Java Console to create the RVGPrimary resource in the appropriate application service group and then set the dependencies for all the resources in the application service group that depend on VMDg to RVGPrimary.

   For more information about using the VCS Java Console, see Cluster Server Administrator's Guide.

6. In the IP Resource Options panel, select Create a new IP resource and click Next.

   If you want to create a copy of an IP resource that already exists in another service group, select Create a copy of an IP resource existing in a different service group. When you select this option, the list of available IP resources are displayed in the Available IP Resources pane. Choose the required IP resource.

   • Verify or enter the virtual IP address; use the IP address that is specified as the Primary IP address when you configured the RDS.

   • Specify the subnet mask.

   • Specify the adapters for each system in the configuration.

   • Click Next.

   • If you had chosen the option to create a copy of an existing IP resource then the panel is filled up as described in the following table

   The Resources box lists the configured resources. Click a resource to view its attributes and their configured values in the Attributes box.

   • If necessary, change the resource names; the wizard assigns unique names to resources based on their respective name rules.

   • To edit a resource name, click the resource name and modify it. Press Enter after editing each resource name. To cancel editing a resource name, press Esc.

   • Click Next to create the replication service group.

7. A warning informing you that the service group is created is displayed. When prompted, click Yes to create the service group.
8. Click Finish to bring the replication service group online.
9. Check the prerequisites, then repeat the wizard at the Secondary site, specifying the appropriate values.

   The name for the application service group must be the same on both sites.

   Repeat the steps on one node of the Secondary cluster.
