2.2.3.3 CLUSTER_OPERATIONAL_VERSION_INFO

  • Article

The CLUSTER_OPERATIONAL_VERSION_INFO structure contains information about the versions of cluster software with which all nodes in the cluster are compatible.

 typedef struct _CLUSTER_OPERATIONAL_VERSION_INFO {
   unsigned long dwSize;
   unsigned long dwClusterHighestVersion;
   unsigned long dwClusterLowestVersion;
   unsigned long dwFlags;
   unsigned long dwReserved;
 } CLUSTER_OPERATIONAL_VERSION_INFO,
  *PCLUSTER_OPERATIONAL_VERSION_INFO;

dwSize: The size, in bytes, of this structure. MUST be set to 20 bytes.

dwClusterHighestVersion: The highest version of cluster software with which all nodes in the cluster are compatible. The upper 2 bytes of dwClusterHighestVersion identify the cluster software internal major version number, and the lower 2 bytes identify the cluster software internal minor version number. Note that the internal version and build numbers are not necessarily identical to the operating system version and build numbers. The dwClusterHighestVersion member SHOULD<23> be set to one of the following values.
