Set-ClusterResourceDependency

Specify the resources that a particular resource depends on within a failover cluster. Existing dependencies will be overwritten by the dependencies that you specify.

Syntax

Set-ClusterResourceDependency [-InputObject <psobject>] [[-Resource] <string>] [[-Dependency] <string>] [-Cluster <string>] [<CommonParameters>]

InputObject
Resource
Dependency
Cluster

Detailed Description

You can use "or" in the expression describing the dependency. An example for using "or": you can set up a dependency where a Network Name resource is dependent on either of two IP Address resources (instead of being dependent on both). This use of "or" dependencies is common in multi-site cluster deployments.

Parameters

Cluster

Specifies the name of the cluster to run this cmdlet on. If you type "-Cluster ." or omit the parameter, the cmdlet runs on the local cluster.

Dependency

Specifies the dependency expression to set for this resource. The format for this is string is "[Resource Name 1] [and|or [Resource Name 2] [...] ]". Resource names should be enclosed in square brackets as [Cluster Disk 2]. Refer to the examples. To reset the resource dependency use an empty string "" in this parameter.

Examples

-------------------------- EXAMPLE 1 --------------------------

Command Prompt: C:\PS>

 
Set-ClusterResourceDependency cluster1FS12 "[IP Address 151.56.48.0]"

Description

-----------

This command makes the resource called cluster1FS12 dependent on [IP Address 151.56.48.0].

-------------------------- EXAMPLE 2 --------------------------

Command Prompt: C:\PS>

 
Set-ClusterResourceDependency cluster1FS12 "[IP Address 151.56.48.0] or [New IP Address]"

Description

-----------

This command makes the resource called cluster1FS12 dependent on either [IP Address 151.56.48.0] or [New IP Address].

-------------------------- EXAMPLE 3 --------------------------

Command Prompt: C:\PS>

 
Set-ClusterResourceDependency cluster1FS12 ""

Description

-----------

This command clears the dependency list for the resource cluster1FS12, so that it no longer depends on any other resources.
