CreateCluster method of the MSCluster_Cluster class

Creates a cluster.

Syntax


void CreateCluster(
  [in] string ClusterName,
  [in] string NodeNames[],
  [in] string IPAddresses[],
  [in] string SubnetMasks[],
  [in] uint32 AdministrativeAccessPoint
);

Parameters

ClusterName [in]

Cluster name.

NodeNames [in]

Node names that will form the cluster.

IPAddresses [in]

IP addresses that the cluster will use.

SubnetMasks [in]

IP address subnet masks or prefix lengths that the cluster will use.

AdministrativeAccessPoint [in]

The type of the cluster management point.

Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, and Windows Server 2008:

Return value

This method does not return a value.

Remarks

Due to delegation issues, by default a multinode cluster cannot be created with one call. To create a multinode cluster, first create the cluster using CreateCluster, wait 30 seconds, and then connect to each of the additional nodes and add them to the cluster using the AddNode method of the MSCluster_Cluster class.

To enable delegation, enable Trusted for delegation for the computer nodes in the directory and enable Kerberos authentication and impersonation level as Delegate when connecting to WMI (this has serious security implications). For more information, see Connecting to a 3rd Computer-Delegation.

Examples
