You cannot configure a Hyper-V virtual machine by using Windows Server 2008 Failover Clustering when the virtual machine uses a storage device that is managed by a third-party clustered file system or a third-party replication solution

Symptoms

When a virtual machine uses a storage device that is managed by a third-party clustered file system or by a third-party replication solution, you cannot configure a Hyper-V virtual machine by using Windows Server 2008 Failover Clustering. You receive the following error message:

There was an error while validating the storage configuration for virtual machine ‘name’. Disk path ‘path’ is not a path to storage in the cluster or to storage that can be added to the cluster.

This issue prevents high availability deployment of Hyper-V under the following circumstances:

  • You use a clustered file system that has a Storage Area Network (SAN).

  • You use a solution that uses replication to keep VHD data consistent between the nodes in the cluster.

Cause

This issue occurs because the Windows Server 2008 Failover Cluster virtual machine High Availability Role Wizard cannot determine whether the storage is located on a shared clustered disk that will be available after a failover. Therefore, the High Availability Role Wizard reports the error message that is mentioned in the "Symptoms" section.

The VHD and all configuration data are required to be shared across all nodes in a cluster. If the VHD and configuration data reside on a local disk, you may have to configure a shared clustered physical disk.

There may be a valid configuration for the High Availability Role Wizard if you are using one of the following to keep virtual machine data synchronized on all nodes:

  • A third-party clustered file system

  • A third-party storage resource

  • A third-party replication solution

However, the High Availability Role Wizard rejects the valid configuration because the High Availability Role Wizard cannot verify configuration.

This hotfix updates the Failover Cluster Management "Configure a Service or Application" business logic that is related to the virtual machine role.

Before you install this hotfix, the High Availability Role Wizard return an error message that states that the configuration cannot be clustered and that the virtual machine will not be added to the cluster. This occurs if a virtual machine is stored on a disk that is not verified by the cluster.

This hotfix changes this error message to a warning message. Additionally, the details of the warning message are provided in the report that is at the end of the wizard. The warning states that the configuration is not located on a storage disk that can verified by the cluster. It does allow for the virtual machine to be added to the cluster or to be made highly available.

You must contact your vendor to make sure that your storage is configured correctly and that virtual machine data is available to all nodes.

Note This hotfix applies only to the Windows Server 2008 x64-based platform.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
