ulFlags: A value from the VDS_SERVICE_FLAG enumeration. Only theVDS_SVF_AUTO_MOUNT_OFF flag is valid for this method.Return Values: The method MUST return zero or a nonerror HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameter:•Verify that ulFlags does not contain any flags that the parameter specification disallows.The server MUST attempt to set the service flags that ulFlags specifies and return an HRESULTindicating failure or success.3.4.5.2.4.16 IVdsService::ClearFlags (Opnum 19)The ClearFlags method clears property flags from the service.HRESULT ClearFlags([in] unsigned long ulFlags);ulFlags: A value from the VDS_SERVICE_FLAG enumeration. Only theVDS_SVF_AUTO_MOUNT_OFF flag is valid for this method.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameter:•Verify that ulFlags does not contain any flags that the parameter specification disallows.The server MUST attempt to clear the service flags that ulFlags specifies and return an HRESULTindicating failure or success.3.4.5.2.5 IVdsServiceInitialization Methods3.4.5.2.5.1 IVdsServiceInitialization::Initialize (Opnum 3)The Initialize method starts the initialization of the server.HRESULT Initialize([in, unique, string] WCHAR* pwszMachineName);pwszMachineName: Reserved; this parameter is not used.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011180 / 360
When the server receives this message, it MUST initialize the server and return a success value(HRESULT of 0x00000000) if the operation is successful, or VDS_E_INITIALIZED_FAILED (HRESULTof 0x80042401) if the operation failed. For more information about initialization, see section 3.4.3.If the IVdsServiceLoader::LoadService method is used to instantiate the server, there is no needto QueryInterface for the IVdsServiceInitialization interface, or to callIVdsServiceInitialization::Initialize. See IVdsServiceLoader::LoadService.3.4.5.2.6 IVdsServiceUninstallDisk Methods3.4.5.2.6.1 IVdsServiceUninstallDisk::GetDiskIdFromLunInfo (Opnum 3)The GetDiskIdFromLunInfo method retrieves the VDS object ID of a disk that corresponds to aspecified LUN information structure.HRESULT GetDiskIdFromLunInfo([in] VDS_LUN_INFORMATION* pLunInfo,[out] VDS_OBJECT_ID* pDiskId);pLunInfo: A pointer to a VDS_LUN_INFORMATION structure that stores the disk's LUNinformation.pDiskId: A pointer to a VDS_OBJECT_ID structure that, if the operation is successfullycompleted, receives the VDS object ID of the disk object that corresponds to the LUNinformation that pLunInfo specifies.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.When the server receives this message, it MUST validate the following parameters:•Verify that pLunInfo is not NULL.•Verify that pDiskId is not NULL.The server MUST set pDiskId to the VDS object identifier of the disk that matches the LUNinformation that pLunInfo specifies, and return an HRESULT that indicates failure or success.3.4.5.2.6.2 IVdsServiceUninstallDisk::UninstallDisks (Opnum 4)The UninstallDisks method uninstalls a specific set of disks when it is given a list of the VDS objectIDs for the disks. All volumes that are contained wholly or partially on the disks are also uninstalled,and the obsolete mount points are removed.HRESULT UninstallDisks([in, size_is(ulCount)] VDS_OBJECT_ID* pDiskIdArray,[in] unsigned long ulCount,[in] boolean bForce,[out] boolean* pbReboot,[out, size_is(ulCount)] HRESULT* pResults);[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011181 / 360
