NOTE:

The Majority Node Set Quorum types for Windows Storage Server 2003 are not supported.

Preventing Quorum Resource Failure

Since the quorum resource plays a crucial role in cluster operation, losing a quorum resource causes the entire cluster to fail. To prevent

cluster failure, configure the quorum resource on a RAID volume in the shared storage system.

NOTICE:

Dell recommends that you use a RAID level other than RAID 0, which is commonly called striping. RAID 0 configurations

provide very high performance, but they do not provide the level of redundancy required for the quorum resource.

Configuring Cluster Networks Running Windows Storage Server 2003

When you install and configure a cluster running Windows Storage Server 2003, the software installation wizard automatically assigns and

configures the public and private networks for your cluster. You can rename a network, allow or disallow the cluster to use a particular

network, or modify the network role using Cluster Administrator. Dell recommends that you configure at least one network for the cluster

interconnect (private network) and one network for all communications.

Verifying MSCS Operation

After you install MSCS, verify that the service is operating properly.

If you selected Cluster Service when you installed the operating system, see "

Obtaining More Information

."

If you did not select Cluster Service when you installed the operating system:

1. Click the Start button and select Programs

Administrative Tools, and then select Services.

2. In the Services window, verify the following:

In the Name column, Cluster Service appears.

In the Status column, Cluster Service is set to Started.

In the Startup Type column, Cluster Service is set to Automatic.

Obtaining More Information

See Microsoft's online help for configuring the Cluster Service.

See "

Using MSCS

" for more information on the Cluster Service.

Verifying Cluster Functionality

To verify cluster functionality, monitor the cluster network communications to ensure that your cluster components are communicating

properly with each other. Also, verify that MSCS is running on the cluster nodes.

Verifying Cluster Resource Availability

In the context of clustering, a resource is a basic unit of failover management. Application programs are made up of resources that are

grouped together for recovery purposes. All recovery groups, and therefore the resources that comprise the recovery groups, must be online

(or in a ready state) for the cluster to function properly.

To verify that the cluster resources are online:
