Resource Dependencies
A dependent resource requires—or depends on—another resource to operate. For example, if a Generic Application resource
requires access to clustered physical storage, it would depend on a physical disk resource.
The following terms describe resources in a dependency relationship:
Dependent resource — A resource that depends on other resources (the dependencies).
Dependency — A resource on which another resource depends.
Dependency tree — A series of dependency relationships such that resource A depends on resource B, resource B
depends on resource C, and so on.
Resources in a dependency tree obey the following rules:
A dependent resource and all of its dependencies must be in the same group.
The Cluster Service takes a dependent resource offline before any of its dependencies are taken offline, and
brings a dependent resource online after all its dependencies are online, as determined by the dependency
hierarchy.
Creating a New Resource
Before you add a resource to your NAS cluster, you must verify that the following elements exist in your cluster:
The type of resource is either one of the basic types provided with MSCS or a custom resource type provided by the
application vendor, Microsoft, or a third party vendor.
A group that contains the resource already exists within your cluster.
All dependent resources have been created.
A separate Resource Monitor—recommended for any resource that has caused problems in the past.
To create a new resource:
1. Click the Start button and select Programs → Administrative Tools→ Cluster Administrator.
The Cluster Administrator window appears.
2. In the console tree (usually the left pane), double-click the Groups folder.
3. In the details pane (usually the right pane), click the group to which you want the resource to belong.
4. On the File menu, point to New, and then click Resource.
5. In the New Resource wizard, type the appropriate information in Name and Description, and click the appropriate
information in Resource type and Group.
6. Click Next.
7. Add or remove possible owners of the resource, and then click Next.
