05/31/2018

[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

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:

Is obtained from Cluster.Version.

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.

' ClusVersion.vbs
' Uses the ClusVersion object to display version information about
' the local cluster.

               CStr(objVers.MinorVersion) & "." & _
               CStr(objVers.BuildNumber)

' Format a string describing the highest compatible version.
' We must extract the upper and lower 16 bits of the 32-bit value.

             ".0." & _
             CStr(CLng(objVers.ClusterHighestVersion And LOW16))
