Dell™ Failover Clusters With 
Microsoft® Windows Server® 2008 
Operating System Important 
Information

Using the Snapshot Virtual Disk Feature of 
Dell PowerVault™ MD3000 in Microsoft 
Windows Server 2008 Failover Clustering

Snapshot Virtual Disk captures point-in-time images of a virtual disk for 
backup, testing, or data processing without affecting the contents of the 
source virtual disk. The Snapshot Virtual Disk can be mapped to the primary 
node (the node owning the source disk) or the secondary node (the node not 
owning the source disk).

For mounting the snapshot volume to the primary node, turn on the 
maintenance mode as described in step 1 to step 5. The snapshot volume is in 
reserved state and thus inaccessible if the maintenance mode for the cluster 
source disk is not turned on.

 

NOTE: In Windows Server 2008 failover clustering you cannot turn on the 

maintenance mode for the witness disk.

The following steps describe the procedure for configuring snapshot in 
Windows Server 2008 failover clustering and mapping it to the primary mode:

1 Turn on Maintenance mode on the source cluster disk using the Failover 

Cluster Management console.

a

Click Start

→ Administrative Tools→ Failover Cluster Management 

console.

b

Right-click the disk for which you want to turn on the maintenance 
mode.
