CLUSCTL_RESOURCE_STORAGE_SET_DRIVELETTER control code

Modifies the drive letter associated with the designated storage-class resource. Applications use this control code as a parameter to the ClusterResourceControl function.


ClusterResourceControl( hResource,                                // resource handle
                        hHostNode,                                // optional node handle
                        CLUSCTL_RESOURCE_STORAGE_SET_DRIVELETTER, // control code
                        lpInBuffer,                               // input buffer: drive letter
                        cbInBufferSize,                           // input buffer size
                        NULL,                                     // output buffer (not used)
                        0,                                        // output buffer size (not used)
                        NULL);                                    // returned data size (not used)

Parameters

The following control code function parameters are specific to this control code. For complete parameter descriptions, see ClusterResourceControl.

lpInBuffer

Pointer to a CLUS_STORAGE_SET_DRIVELETTER structure specifying the drive letter.

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.

System error code

The operation failed. The value of lpcbBytesReturned is unreliable.
