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.
-
The operation failed. The value of lpcbBytesReturned is unreliable.
