In this configuration, decide ifyou want the service group to be a parallel service group. If so, you may need tolocalize certain attributes for resources in the service group. For example, youhave to change the IP resource's Address attribute for each node.Figure 2-2Zone root on local disks with direct mount file systemApplicationIPMountNICZoneDiskGroupManagesmounting andumounting theApplication filesystemResource dependency diagrams: zone root on shared disksThe following resource dependency diagrams show zone configurations on shareddisks configured for loopback and direct mounted file systems.Figure 2-3 depicts the dependency diagram when a zone root is set up on sharedstorage with the loopback file system.
