•Set the pHrResult output parameter based on the return code for the asynchronous operation. Ifthe asynchronous operation is still in progress, this parameter MUST be set toVDS_E_OPERATION_PENDING (HRESULT of 0x00042409).•Set the pulPercentCompleted output parameter based on the completion percentage of theasynchronous operation.•Return an HRESULT that indicates success or failure for the QueryStatus method.3.4.5.2.3 IVdsServiceLoader Methods3.4.5.2.3.1 IVdsServiceLoader::LoadService (Opnum 3)The LoadService method is used by client applications to load the VDS service on a remotemachine.HRESULT LoadService([in, unique, string] LPWSTR pwszMachineName,[out] IVdsService** ppService);pwszMachineName: A pointer to a string that contains the name of the machine on which theloader should load the VDS service.ppService: A pointer to the IVdsService interface that, if successfully completed, returns theIVdsService interface to the VDS service that runs on the machine represented bypwszMachineName.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 ppService is not NULL.The server MUST:•Load the VDS service on the computer specified by pwszMachineName parameter.•QueryInterface for the IVdsServiceInitialization interface.•Call the IVdsServiceInitialization::Initialize method, passing the pwszMachineNameparameter input to this method.•Point ppService to the IVdsService interface for the VDS service that is loaded.•Return an HRESULT that indicates failure or success.The server object that is created when this method is called MUST implement only these interfaces:•IVdsService•IVdsServiceHba•IVdsServiceIscsi[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011172 / 360
•IVdsServiceUninstallDisk•IVdsServiceSAN3.4.5.2.4 IVdsService Methods3.4.5.2.4.1 IVdsService::IsServiceReady (Opnum 3)The IsServiceReady method determines whether a service is finished initializing. Until the serviceinitialization completes, an application SHOULD NOT call any method other thanGetProperties.HRESULT IsServiceReady();This method has no parameters.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 2.2.3.3.4.5.2.4.2 IVdsService::WaitForServiceReady (Opnum 4)The WaitForServiceReady method waits for VDS initialization to complete and returns the statusof the VDS initialization in the HRESULT.HRESULT WaitForServiceReady();This method has no parameters.Return Values: The method MUST return zero to indicate success or the error codeVDS_E_INITIALIZED_FAILED if the service-ready state is "failed".Upon receiving this message, if the service-ready state is or becomes "failed", the server MUSTreturn VDS_E_INITIALIZED_FAILED (HRESULT of 0x80042401). The server MUST block the call untilthe service-ready state is "ready", after which it MUST return success (HRESULT of 0x00000000).3.4.5.2.4.3 IVdsService::GetProperties (Opnum 5)The GetProperties method retrieves the properties of the service that is represented by the objectthat exposes this interface and method.HRESULT GetProperties([out] VDS_SERVICE_PROP* pServiceProp);pServiceProp: A pointer to a VDS_SERVICE_PROP structure that, if the operation issuccessfully completed, receives the properties of the service.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, 2011173 / 360
