CLUSCTL_RESOURCE_STORAGE_GET_DISK_INFO_EX2 control code
Retrieves extended information about a storage class resource.
Applications use this control code as a parameter to the ClusterResourceControl function, and resource DLLs receive the control code as a parameter to the ResourceControl callback function.
This control code uses CLUSPROP_PARTITION_INFO_EX2 structures to provide more information than the CLUSCTL_RESOURCE_STORAGE_GET_DISK_INFO_EX control code.
ClusterResourceControl( hResource, // resource handle
hHostNode, // optional host node
CLUSCTL_RESOURCE_STORAGE_GET_DISK_INFO_EX2, // this control code
NULL, // not used
0, // not used
lpOutBuffer, // output buffer: value list
cbOutBufferSize, // allocated buffer size (bytes)
lpcbBytesReturned ); // size of output data (bytes)
Parameters
The following control code function and DLL support parameters are specific to this control code. For complete parameter descriptions, see ClusterResourceControl or ResourceControl.
-
lpOutBuffer
-
On a successful return, points to a value list that describes the storage class resource. The value list is made up of CLUSPROP_PARTITION_INFO_EX2 structures.
Return value
ClusterResourceControl returns one of the following values:
-
ERROR_SUCCESS
-
0
The operation was successful. The lpcbBytesReturned parameter points to the actual size of the returned data.
-
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.
-
The operation failed. The value of lpcbBytesReturned is unreliable.
Implementations of ResourceControl 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).
