Add a resource to the service; click Add a resource to this service. Clicking Add a resourceto this service causes the display of two drop-down boxes: Add a new local resource and Usean existing global resource. Adding a new local resource adds a resource that is available onlyto this service. The process of adding a local resource is the same as adding a global resourcedescribed in Section 3.8, “Adding Cluster Resources”. Adding a global resource adds a resourcethat has been previously added as a global resource (refer to Section 3.8, “Adding ClusterResources”).5. At the drop-down box of either Add a new local resource or Use an existing global resource,select the resource to add and configure it according to the options presented. (The options arethe same as described in Section 3.8, “Adding Cluster Resources”.)NoteIf you are adding a Samba-service resource, connect a Samba-service resourcedirectly to the service, not to a resource within a service.6. If you want to add resources to that resource, click Add a child. Clicking Add a child causesthe display of additional options to local and global resources. You can continue adding childrenresources to the resource to suit your requirements. To view children resources, click the triangleicon to the left of Show Children.7.
