Support for Microsoft Cluster Shared Volumes

You can use SnapDrive for Windows supports LUN provisioning and Snapshot copy management on Microsoft Cluster Shared Volumes (CSVs) using Hyper-V with Windows Server 2008 R2.

Cluster Shared Volumes is an option added to the Failover Clustering feature in Windows Server 2008 R2 that enables all nodes in the same Microsoft cluster concurrent access to files on each CSV-enabled shared LUN. CSV allows multiple virtual hard disks from different virtual machines to be stored on a single LUN.

Note: If you enable CSV after installing SnapDrive for Windows, you must restart the SnapDrive service and close and reopen SnapDrive MMC.

SnapDrive for Windows recommendation when using CSVs
To ensure that Microsoft Cluster Shared Volumes display properly when using SnapDrive for Windows, you must first enable the Hyper-V server role in Windows Server 2008 R2. This is necessary because SnapDrive uses the Hyper-V server role to tag the disk as a CSV, enabling live migration of virtual machines.
Verifying the cluster group owner
Before you use SnapDrive for Windows to add new Cluster Shared Volumes (CSV) to a Microsoft cluster, it is important to verify which Hyper-V node owns the cluster group because you must create new CSV LUNs on the node that owns the cluster group.
Changing the cluster group owner
You must create new CSV LUNs on the node that owns the cluster group. If you are using SnapDrive for Windows to create a new CSV LUN on a Hyper-V node that is not the cluster group owner, you can move ownership to the current node. The disk create operation might fail if either the specified cluster node is not the owner of the resource, or the node is not a possible owner of the resource.
