CLUSCTL_RESOURCE_TYPE_STORAGE_GET_AVAILABLE_DISKS_EX2_INT control code

Retrieves information about storage class devices supported by a resource type. Applications use this control code as a parameter to the ClusterResourceTypeControl function, and resource DLLs receive the control code as a parameter to the ResourceTypeControl callback function. Unlike the CLUSCTL_RESOURCE_TYPE_STORAGE_GET_AVAILABLE_DISKS control code, the value list returned contains CLUSPROP_PARTITION_INFO_EX structures.

ClusterResourceTypeControl( 
  hCluster,                  // cluster handle
  lpszResourceTypeName,      // resource type name
  hHostNode,                 // optional host node
  CLUSCTL_RESOURCE_TYPE_STORAGE_GET_AVAILABLE_DISKS_EX2_INT,  // this control code
  lpInBuffer,                // input buffer
  nInBufferSize,             // input buffer size (not used)
  lpOutBuffer,               // output buffer
  cbOutBufferSize,           // allocated buffer size
  lpcbBytesReturned );       // size of returned data

Parameters

The following control code function and DLL support parameters are specific to this control code. For complete parameter descriptions, see ClusterResourceTypeControl or ResourceTypeControl.

lpOutBuffer

On a successful return, points to a value list describing all available storage class devices in the cluster supported by the resource type specified by lpszResTypeName.

  • For information on the format of this list see Value Lists for Storage Class Resources.
  • A storage class device is available if it is not currently owned by a node. Because resources are always owned by a node at any point in time, storage class devices configured as resources will not be included in the returned value list.
  • Any given storage class resource can appear more than once in the list.

Return value

ClusterResourceTypeControl returns one of the following values:

ERROR_SUCCESS

0

The operation was successful.

ERROR_MORE_DATA

234 (0xEA)

The output buffer pointed to by lpOutBuffer was not large enough to hold the data resulting from the operation. The lpcbBytesReturned parameter points to the size required for the output buffer.

System error code

The operation failed. The value of lpcbBytesReturned is unreliable.

Implementations of ResourceTypeControl can return the above values or the following value:

ERROR_INVALID_FUNCTION

1

Requests that the Resource Monitor perform default processing (if any) for the control code addition to processing supplied by the DLL (if any).
