Preparing Your Systems for Clustering 29

Assign the drive letters for the drives.

This procedure allows Windows to mount the volumes.

Reassign the drive letter, if necessary.

To reassign the drive letter:

• With the mouse pointer on the same icon, right-click and select

Change Drive Letter and Path

from the submenu.

• Click

Edit

, select the letter you want to assign the drive (for

example, Z), and then click

• Click

Yes

to confirm the changes.

Power down the node.

If the cables are connected properly, the drive order is the same as is on

each node, and the drive letter assignments of all the cluster nodes follow

the same order as on node 1. The volume labels can also be used to

double-check the drive order by ensuring that the disk with volume label

"Volume Z" is assigned to drive letter Z and so on for each disk on each

node. Assign drive letters on each of the shared disks, even if the disk

displays the drive letter correctly.

Configuring Your Failover Cluster

MSCS is an integrated service in Windows Server 2003 which is required for

configuring your failover cluster. 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 in the event that one of the nodes fails or

goes offline. To provide application failover for the cluster, the MSCS

software must be installed on each cluster node. For more information, see

"Understanding Your Failover Cluster" on page 37.
