Installing and Configuring MSCS
MSCS is an integrated service in the Windows Storage Server 2003, Enterprise Edition operating system. MSCS performs the
basic cluster functionality, which includes membership, communication, and failover management. When MSCS is installed
properly, the service starts on each node and responds automatically if one of the nodes fails or goes offline. To provide
application failover for the cluster, the MSCS software must be installed on both cluster nodes.
See " Using MSCS " for more information.
NOTE: For systems with split backplane modules installed, the cluster installation tries to use the logical drives on the
secondary backplane as cluster disks. Because these drives are not accessible to all nodes in the cluster, ensure that
they are removed from the cluster after the installation is complete.
NOTE: In Windows Storage Server 2003, Enterprise Edition, mapping a network drive to the same drive letter as a
cluster disk resource renders the cluster disk inaccessible from Windows Explorer on the host. Ensure that mapped
network drives and cluster disks are never assigned the same drive letter.
Verifying Cluster Readiness
To ensure that your server and storage systems are ready for MSCS installation, ensure that these systems are functioning
correctly and verify the following:
All cluster servers are able to log on to the same domain.
The shared disks are partitioned and formatted, and the same drive letters that reference logical drives on the shared
storage system are used on each node.
For each attached PowerVault 22xS storage system, the split-bus module is set to cluster mode before power-up.
Cluster mode is enabled on all PERC cards connected to shared storage.
The controller's SCSI IDs (6 or 7) on each node are different.
All peer PERC cards are connected to the same PowerVault system through the same channel number.
All IP addresses and network names for each system node are communicating with each other and the rest of the
network. The private IP addresses should not be accessible from the LAN.
Configuring Microsoft Windows Storage Server 2003, Enterprise Edition

The cluster setup files are automatically installed on the system disk.
To create a new cluster:
1. From either node, click the Start button, select Programs → Administrative Tools, and then double-click Cluster
Administrator.
2. From the File menu, select Open Connection.
3. In the Action box of the Open Connection to Cluster, select Create new cluster.
The New Server Cluster Wizard appears.
