CLUSCTL_RESOURCE_SET_PRIVATE_PROPERTIES control code

Updates the read/write private properties for a resource. Applications use this control code as a ClusterResourceControl parameter, and resource DLLs receive the control code as a ResourceControl parameter.

ClusterResourceControl( hResource,                               // resource handle
                        hHostNode,                               // optional host node
                        CLUSCTL_RESOURCE_SET_PRIVATE_PROPERTIES, // this control code
                        lpInBuffer,                              // input buffer: property list
                        cbInBufferSize,                          // allocated buffer size (bytes)
                        NULL,                                    // output buffer: (not used)
                        0,                                       // output buffer size (not used)
                        NULL );                                  // actual size of resulting data (not used)

Parameters

The following control code function and DLL support parameter is specific to this control code. For complete parameter descriptions, see ClusterResourceControl or ResourceControl.

lpInBuffer

Points to a property list containing one or more read/write private resource properties.

Return value

ClusterResourceControl returns one of the following values.

ERROR_SUCCESS

0

The operation completed successfully. The property list is correctly formatted and contains valid data values.

ERROR_INSUFFICIENT_BUFFER

122 (0x7A)

The data area passed to a system call is too small. The actual size of the property list buffer as determined by the Cluster service is larger than the size specified in the cbInBufferSize parameter.

ERROR_INVALID_DATA

13 (0xD)

The data is invalid. The property list is either formatted incorrectly or contains invalid data, such as an out-of-range value.

ERROR_INVALID_PARAMETER

87 (0x57)

The parameter is incorrect. The property list is not formatted correctly.

RPC_X_BAD_STUB_DATA

1783 (0x6F7)

The stub received bad data. The lpInBuffer parameter is NULL.

ERROR_RESOURCE_PROPERTIES_STORED

5024 (0x13A0)

The properties were stored but not all changes will take effect until the next time the resource is brought online.

System error code

If any other values are returned, then the operation failed.

Implementations of ResourceControl can return the above values or the following value.

ERROR_INVALID_FUNCTION

1

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

Remarks

Do not use this control code in any resource DLL entry point function. This control code can safely be called from a worker thread. For more information, see Function Calls to Avoid in Resource DLLs.

Resource DLL Support

Required. Always support the CLUSCTL_RESOURCE_SET_PRIVATE_PROPERTIES control code in your implementation of ResourceControl. This allows you to validate the property values before writing them to the cluster database. Be sure to return ERROR_RESOURCE_PROPERTIES_STORED if the new property values do not take effect immediately for the resource.

If you do not support this control code, the Resource Monitor uses the unvalidated content of InBuffer to update the cluster database, which can result in invalid properties being specified for your resource.

As a general guideline, the Resource Monitor should handle all of the control codes for common properties, while your DLL should handle all control codes for private properties.

For more information on the ResourceControl entry point, see Implementing ResourceControl.
