Configuring Resources With the Failover Cluster Automation Server

Article

[The Failover Cluster Automation Server is available for use in Windows Server 2008. It may be altered or unavailable in subsequent versions.]

The following example creates resources of different types, satisfying required private properties and required dependencies as necessary. The example consists of two separate files, CreateResource.vbs and CreateResource.wsf.

' Global data and functions supporting CreateResource.wsf.

Option Explicit

' In CreateResource.wsf, each resource type assigns appropriate 
' values to these global variables. The CreateResource function 
' uses these values to parse the command-line arguments and assign 
' values to the required private properties for a given resource type.

Public intBasicArgs, intMinArgs, intMaxArgs, intReqDeps

;  CreateResource.wsf  (requires CreateResource.vbs to run!)
;
;  Creates resources of different types.  To create a resource of
;  a given type, use the resource type name as a job ID.  Each
;  resource type will have a different syntax depending
;  on its required private properties.
;
;  Basic syntax:
;     cscript //job:[object type] CreateResource.wsf cluster group resource prop1, prop2, ... , propN
;
;  Refer to the syntax string in each job for specific commands.
