44 Understanding Your Failover Cluster
Resource Dependencies
A dependent resource requires another resource to operate. Table 4-4
describes resource dependencies.
Creating a New Resource
Before you add a resource to your cluster solution, verify that the following
conditions exist in your cluster:
• The type of resource is either a standard resource provided with MSCS or a
custom resource provided by Microsoft or a third party vendor.
• A group that will contain the resource already exists within your cluster.
• All dependent resources have been created.
• A separate Resource Monitor exists (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, double-click the Groups folder.
3 Select the group to which you want the resource to belong.

Dependency A resource on which another resource depends.
Dependency tree A series of dependency relationships or hierarchy.
The following rules apply to a dependency tree:
• A dependent resource and its dependencies must be in the
same group.
• A dependent resource is taken offline before its dependencies
and brought online after its dependencies, as determined by
the dependency hierarchy.
