CLUSCTL_RESOURCE_TYPE_STORAGE_GET_DISKID control code
Queries the ID of a disk on the designated node. Applications use this control code as a parameter to ClusterResourceTypeControl function, and resource DLLs receive the control code as a parameter to the ResourceTypeControl callback function.
ClusterResourceTypeControl( hCluster, // cluster handle
lpszResTypeName, // resource type name
hHostNode, // optional host node
CLUSCTL_RESOURCE_TYPE_STORAGE_GET_DISKID, // this control code
lpInBuffer, // input buffer: file path
cbInBufferSize, // input buffer size
lpOutBuffer, // output buffer: Disk ID
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.
-
lpInBuffer
-
A null-terminated string representing the file path on the target disk.
-
lpOutBuffer
-
Points to the disk id in the following format.
- A 32-bit integer indicating ID type. Valid values for this field are 0x00000001 for MBR disks, 0x00000002 for GPT disks, and 0x00001388 for disks whose partition type is unknown.
- A 32-bit integer if the preceding ID type is MBR or a 128-bitfield if the preceding ID type is GPT.
Return value
ClusterResourceTypeControl returns one of the following values.
-
ERROR_SUCCESS
-
0
The operation completed successfully.
-
ERROR_MORE_DATA
-
234 (0xEA)
More data is available. 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.
-
If any other value is returned, then the operation failed. The value of lpcbBytesReturned is unreliable.
