Preparing Your Systems for Clustering
Configuring Hard Drive Letters When Using Multiple Shared Storage
Systems
Before creating the cluster, ensure that both nodes have the same view of the
shared storage systems. Because each node has access to hard drives that are
in a common storage array, each node must have identical drive letters
assigned to each hard drive. Using volume mount points in Windows Server
2008, your cluster can access more than 22 volumes.
NOTE:
Drive letters A through D are reserved for the local system.
To ensure that hard drive letter assignments are identical:
1 Ensure that your cables are attached to the shared storage devices in the
proper sequence.
You can view all storage devices using the Windows Server 2008 Disk
Management console.
2 To maintain proper drive letter assignments, ensure that each storage
connection port on the storage device is enumerated by each node. Also,
ensure that each storage connection port is connected to the same RAID
controller, storage processor, or SAN switch.
For more information on the location of the RAID controllers or storage
processors on your shared storage array, see "Cabling Your Cluster
Hardware" in the Dell Failover Cluster Hardware Installation and
Troubleshooting Guide for the specific storage array on the Dell Support
website at support.dell.com.
3 Go to "Formatting and Assigning Drive Letters and Volume Labels to the Disks"
on page 28.
Formatting and Assigning Drive Letters and Volume Labels to the Disks
1 Open Disk Management on the Server Manager.
2 Ensure that the shared disks are Online. Format the disks, assign the drive
letters and volume labels on node 1 by using the Windows Disk
Management utility.
For example, create volumes labeled "Volume Y" for disk Y and "Volume Z"
for disk Z.
