ClusVersion object

[The ClusVersion object is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

Provides version information about the operating system and the Cluster service. For more information on cluster versions and version numbers, see Version Compatibility.

Members

The ClusVersion object has these types of members:

Properties

The ClusVersion object has these properties.

Property Description
BuildNumber
Returns the build number of the operating system installed on the local node.
ClusterHighestVersion
Returns the current value of ClusterHighestVersion.
ClusterLowestVersion
Returns the current value of ClusterLowestVersion
CSDVersion
Returns the number of the latest Service Pack installed on the local node.
Flags
Returns any cluster version flags set in the cluster.
MajorVersion
Returns the major version number of the operating system installed on the local node.
MinorVersion
Returns the major version number of the operating system installed on the local node.
MixedVersion
Indicates whether different versions of the Cluster service are present in the cluster.
Name
Returns the name of the cluster.
VendorId
Returns vendor identification information for the version of Cluster service installed on the local node.

Remarks

A ClusVersion collection:

Some of the ClusVersion properties correspond to dynamic values maintained internally by the cluster. A ClusVersion object is instantiated with a snapshot of those values and stores them statically. Therefore, the ClusVersion property values represent the state of the cluster when the object was first created. To obtain the latest version information from the cluster, create a new ClusVersion object.

For more information about the versioning process see Version Compatibility.

Examples

The following script instantiates and uses a ClusVersion object.
