Creating a Resource Dependency

While most Recovery Kits create their dependencies during the original resource hierarchy creation task, under certain circumstances, you may want to create new or additional resource dependencies or delete existing ones. An example might be that you wish to change an existing IP dependency to another IP address. Instead of deleting the entire resource hierarchy and creating a new one, you can delete the existing IP dependency and create a new dependency with a different IP address.

1. There are four possible ways to begin.

• Right-click on the icon for the parent server-specific resource under the server, or the parent global resource,
to which you want to add a parent-child dependency. When the resource context menu appears, click Create Dependency.

Note: If you right-clicked on a server-specific resource in the right pane, the value of the Server will be that server. If you right-clicked on a global resource in the left pane, the value of the Server will be the server where the resource has the highest priority.

• On the global toolbar, click the Create Dependency button. When the dialog comes up, select the server in the Server list from which you want to begin creating the resource dependency, and click Next. On the next dialog, select the parent resource from the Parent Resource Tag list, and click Next again.

• On the resource context toolbar, if displayed, click the Create Dependency button.

• On the Edit menu, point to Resource and then click Create Dependency. When the dialog comes up, select the server in the Server list from which you want to begin creating the resource dependency, and click Next.

• On the next dialog, select the parent resource from the Parent Resource Tag list, and click Next again.

2. Select a Child Resource Tag from the drop down box of existing and valid resources on the server. The dialog will display all the resources available on the server with the following exceptions:

• The parent resource, its ancestors, and its children.

• A resource that has not been extended to the same servers as the parent resource.

• A resource that does not have the same relative priority as the parent resource.

• Any resource that is not in-service on the same server as the parent, if the parent resource is in-service.

Click Next to proceed to the next dialog.

3. The dialog will then confirm that you have selected the appropriate parent and child resource tags for your dependency creation. Click Create Dependency to create the dependency on all servers in the cluster to which the parent has been extended.

4. If the output panel is enabled, the dialog closes, and the results of the commands to create the dependency are shown in the output panel. If not, the dialog remains up to show these results, and you click Done to finish when all results have been displayed.
