the group's resources and can be modified by an Administrator.
To maximize the processing power of a cluster, establish at least as many groups as there are nodes in the cluster.
Cluster Resources
A cluster resource is any physical or logical component that has the following characteristics:
Can be brought online and taken offline
Can be managed in a server cluster
Can be hosted (owned) by only one node at a time
To manage resources, MSCS communicates to a resource DLL through a Resource Monitor. When MSCS makes a request of a
resource, the Resource Monitor calls the appropriate entry-point function in the resource DLL to check and control the
resource's state.
Dependent Resources
A dependent resource requires another resource to operate. For example, a network name must be associated with an IP
address. Because of this requirement, a network name resource is dependent on an IP address resource. A resource can
specify one or more resources on which it is dependent. A resource can also specify a list of nodes on which it is able to run.
Preferred nodes and dependencies are important considerations when administrators organize resources into groups.
Dependent resources are taken offline before the resources upon which they depend are taken offline, likewise, they are
brought online after the resources on which they depend are brought online.
Setting Resource Properties
Using the resource Properties dialog box, you can perform the following tasks:
View or change the resource name
View or change the resource description and possible owners
Assign a separate memory space for the resource
View the resource type, group ownership, and resource state
View which node currently owns the resource
View pre-existing dependencies and modify resource dependencies
Specify whether to restart a resource and the settings used to restart the resource (if required)
Check the online state of the resource by configuring the Looks Alive and Is Alive polling intervals in MSCS
Specify the time requirement for resolving a resource in a pending state (Online Pending or Offline Pending) before
MSCS places the resource in Offline or Failed status
Set specific resource parameters
The General, Dependencies, and Advanced tabs are the same for every resource. Some resource types support additional
