It is easier to configure high availability in Windows Server 2008 failover clusters then it is in earlier versions of Microsoft clustering technology. In Windows Server 2008, you can use the Failover Cluster Management snap-in to configure highly available services or highly available applications. The Failover Cluster Management snap-in involves some configuration wizards that enable you to configure high availability for specific types of services or applications on a step-by-step basis.
For example, you can use these wizards to configure file servers, Distributed File System (DFS) namespaces, print servers, and so on. After you complete a wizard, a service group or an application group is set to the “Online” state on one of the nodes in the failover cluster.
One of the design goals for Windows Server 2008 failover clustering is to make the configuration and the administration of a cluster much easier for users. To achieve this goal, many configuration wizards are used to configure high availability on a step-by-step basis. Most of the time, the Configure a Service or Application action is used to start the High Availability Wizard. However, some advanced procedures are required to configure additional cluster resources in some highly available application groups or services groups that are already configured.
The Add a resource action is available for all highly available service groups or application groups. You can use this action to configure the following resources:
After you create and configure a resource by using the Add a resource action, the resource is set to the “Offline” state. This enables you to complete additional configurations.
All resources that do not use the New Resource Wizard require some additional configurations. To perform these additional configurations, you must understand how cluster resources work and what additional configuration steps are required for each resource type. You must also know whether a role or a feature must be configured to support the resource. For example, if you add a Print Spooler resource, you must complete the following additional configuration steps before you bring the resource to the “Online” state:
