SnapDrive for Windows and Windows Server 2008 provides a simpler way of configuring a shared disk as a witness disk than in earlier versions of SnapDrive and Windows Server. While SnapDrive still supports the previous method of configuring a quorum, it is no longer necessary to create a shared disk before creating a cluster, nor is it necessary to connect that shared disk to the node before that node can be added to the cluster.
Before you begin
- Install the Windows Server 2008 failover cluster feature.
For more information, see Windows Server 2008 online Help.
- Create the failover cluster using Windows Server 2008 MMC snap-in, Failover Cluster Management.
For more information, see Windows Server 2008 online Help.
- Create a shared LUN, ensuring that you select the Microsoft Cluster Services Group named "Cluster Group" to own that disk resource.
Note: The shared LUN must be created on the node that owns "Cluster Group." To determine which node owns "Cluster Group," type the
cluster group command at a Windows command prompt.
Steps
- Navigating to to launch the Windows Server 2008 Failover Cluster Management snap-in.
