Understanding Your Failover Cluster
43
A dependent resource requires another resource to operate. Table 4-3
describes resource dependencies.
Creating a Resource
1 Open the Failover Clustering console, right-click on the resource that you
want to modify, and click Properties.
2 Under the Dependencies tab, you can specify the resources that must be
brought online before your resource can come online. You can add
multiple dependencies using AND or OR.
If you use AND, all the dependent resources must come online before your
resource can come online. If you use OR, any one of the dependent
resources must come online before your resource can come online.
3 To view the Resource Dependency diagram, right-click on the resource
and select the Show Dependency Report option.
NOTE:
You must configure the required dependencies before you create the
resource.

Dependency A resource on which another resource depends.
Dependency tree A series of dependency relationships or hierarchy.

and brought online after its dependencies, as determined by
the dependency hierarchy.
