[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

The server MUST perform the following. Errors generated in this sequence of steps are returned inthe pHrResult parameter to the IVdsAsync::Wait or IVdsAsyncQueryStatus methods.•If the operating system is unable to format the device with the file system type specified usingthe type parameter, then this method MUST return VDS_E_INCOMPATIBLE_FILE_SYSTEM.•If the target device\media is write-protected, then this method MUST returnVDS_E_MEDIA_WRITE_PROTECTED.•If the pwszLabel parameter is incompatible with the file system type specified using the typeparameter, then the server MUST return VDS_E_BAD_LABEL.•If the specified file system type has a minimum volume size requirement and that requirement isnot met, then the server MUST return VDS_E_VOLUME_TOO_SMALL.•If the specified file system type has a maximum volume size requirement and that requirement isnot met, then the server MUST return VDS_E_VOLUME_TOO_BIG.•If the specified file system type has a minimum or maximum cluster size requirement and thatrequirement is not met, then the server MUST return VDS_E_CLUSTER_SIZE_TOO_SMALL orVDS_E_CLUSTER_SIZE_TOO_BIG, respectively.•If the specified file system type has a maximum cluster count requirement and that requirementis not met, then the server MUST return VDS_E_CLUSTER_COUNT_BEYOND_32BITS.The server MUST update the percentage completed value periodically during the following sequence,and send progress notifications to all clients. How often the percentage completed is updated, and atwhat point in the sequence, is implementation specific. To send progress notifications to the clients:•For each callback object registered in the list of callback objects, call the callback object'sIVdsAdviseSink::OnNotify (Opnum 3)method with a VDS_NOTIFICATION structure withthe following attributes:•objectType member is VDS_NTT_FILE_SYSTEM.•FileSystem member is a VDS_FILE_SYSTEM_NOTIFICATION with the followingattributes:•ulEvent is VDS_NF_FILE_SYSTEM_FORMAT_PROGRESS.•volumeId is set to GUID_NULL.•dwPercentCompleted is the percentage completed value.The server MUST then perform the following in sequence:•Format the partition following the parameters specified to the method.•If VDS_FSOF_COMPRESSION is specified and the file system being formatted supportscompression, compress the file system after formatting is complete.•Set the return code in the async object to an HRESULT indicating failure or success.•If the server was required to compress the file system after formatting but could not, thereturn code MUST be set to VDS_S_VOLUME_COMPRESS_FAILED (HRESULT of 0x00042443).•If the task completed successfully, set the percentage completed value in the async object to100.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011233 / 360
