Configuring service groups using the Application Configuration Wizard

Configuring the service group for any additional application involves creating an application service group and defining the attribute values for its resources. This can be done using the Application Configuration Wizard. After the service group is created, you must configure the shares to mount automatically at startup.

The Application Configuration Wizard enables you to create service group for the application resources and other VCS components configured using the wizard. This topic describes how to create the service group using the wizard.

If you are using a non-shared storage configuration (dynamic disk groups configured on local disks), you have to configure the service group manually either using the Cluster Manager (Java Console) or the command line. The wizard currently cannot configure resources (VMNSDg agent) required for monitoring non-shared storage.

See Configuring the service group in a non-shared storage environment.

To configure a service group using the wizard

  1. In the Application Options panel, click Configure application dependency and create service group.

    The option is enabled only if the following conditions are met:

    • Resources and VCS components are already configured using the wizard.

    • You clicked Modify Service Groups in the Wizard Options panel.

  2. Specify the dependency between the applications.

    You must have at least two resources configured for this dialog box to appear. Of the two resources, one should either be a GenericService or a Process resource.

    • From the Select Application list, select the application that would depend on other applications. The selected application becomes the parent application.

    • From the Available Applications list, select the application on which the parent application would depend and click the right-arrow icon to move the application to the Child Applications list.

      To remove an application from the Child Applications list, select the application in the list and click the left arrow.

    • Repeat these steps for all such applications for which you want to create a dependency.

      Click Next.

      The Application Dependency dialog box enables you to link resources configured using the wizard. If these resources are dependent on other services outside the VCS environment, you should first configure resources for such services and then create the appropriate dependency.

  3. On the Service Group Summary panel, review the service group configuration and click Next.

    The following service group details are visible:

    Resources

    Displays a list of configured resources. The wizard assigns unique names to resources. Change the names of resource, if required.

    To edit a resource name, select the resource name and either click it or press the F2 key. Edit the resource name and then press the Enter key to confirm the changes. To cancel editing a resource name, press the Esc key.

    Attributes

    Displays the attributes and their configured values, for a resource selected in the Resources list.

    Enable FastFailOver attribute for all the VMDg resources in the service group

    This is applicable in case of SFW HA only.

    To enable all the VMDg resources in the service group for fast failover, select this checkbox.
  4. Click Yes on the dialog that prompts you that the wizard will run commands to modify the service group configuration.
  5. In the completion panel, check Bring the service group online if you want to bring the service group online on the local system.
  6. Click Finish to create the service group and exit the Application Configuration Wizard.
