The server MUST update the percentage completed value periodically during the precedingsequence. How often the percentage completed is updated, and at what point in the sequence, isimplementation-specific.3.4.5.2.38 IVdsVDisk Methods3.4.5.2.38.1 IVdsVDisk::Open (Opnum 3)The Open method opens a handle to the specified virtual disk file and returns an IVdsOpenVDisk(section 3.1.15.2) interface pointer to an object representing the open virtual disk (anOpenVirtualDisk object). Release the IVdsOpenVDisk interface to close the handle to the virtual disk.HRESULT Open([in] VIRTUAL_DISK_ACCESS_MASK AccessMask,[in] OPEN_VIRTUAL_DISK_FLAG Flags,[in] ULONG ReadWriteDepth,[out] IVdsOpenVDisk** ppOpenVDisk);AccessMask: A VIRTUAL_DISK_ACCESS_MASK (section 2.2.2.18.1.4) structure thatcontains the set of access rights to be applied to the opened virtual disk.Flags: A bitmask of OPEN_VIRTUAL_DISK_FLAG (section 2.2.2.18.1.2) flags specifying howthe virtual disk is to be opened.ReadWriteDepth: This is applicable only to differencing type virtual disks. The number ofbacking stores (files) to open read/write. This count includes the child. The remaining stores inthe differencing chain MUST be opened as read-only. For example, given a differencing diskwith two parents (diskA is the differencing disk whose parent is diskB, and since diskB is adifferencing disk, it has a parent which is diskC), entering '2' for this parameter will open thedifferencing disk (diskA) and the parent used to create this differencing disk (diskB) as readwrite.In this case, diskB is also a differencing disk and its parent (diskC) is opened as readonly.ppOpenVDisk: A pointer to a variable that, if the operation is successfully completed, receivesan IVdsOpenVDisk interface pointer to the newly opened virtual disk object. Callers MUSTrelease the interface pointer when it is no longer needed by calling the IUnknown::Releasemethod.Return Values: The method MUST return zero to indicate success, or return an implementationspecificnonzero error code to indicate failure.When the server receives this message, it MUST validate the following parameters:•Verify that ppOpenVDisk is not NULL.The server MUST then perform the following in sequence:•Pass the input parameters to the operating system to open the virtual disk file.•If the operating system failed to open the file, return an implementation-specific error code.Otherwise, if the file was successfully opened, the server MUST:•Mark the state of the object that implements IVdsVDisk as "open".

•Create an object that implements the IVdsOpenVDisk interface to represent the virtual diskfile in the open state.•Point ppOpenVDisk to an IVdsOpenVDisk interface of the virtual disk object created andreturn an HRESULT indicating success.3.4.5.2.38.2 IVdsVDisk::GetProperties (Opnum 4)The GetProperties method returns details of the virtual disk.HRESULT GetProperties([out] PVDS_VDISK_PROPERTIES pDiskProperties);pDiskProperties: Receives a pointer to a VDS_VDISK_PROPERTIES (section 2.2.2.18.2.1)structure containing the disk property information.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 pDiskProperties is not NULL.The server MUST perform the following:•Fill all the fields of VDS_VDISK_PROPERTIES.•Return an HRESULT indicating failure or success.3.4.5.2.38.3 IVdsVDisk::GetHostVolume (Opnum 5)The GetHostVolume method returns an interface pointer to the volume object for the volume onwhich the virtual disk backing store file resides.HRESULT GetHostVolume([out] IVdsVolume** ppVolume);ppVolume: Pointer to a variable that receives an IVdsVolume (section 3.1.13.1) interfacepointer for the volume. Callers MUST release the interface pointer when it is no longer neededby calling the IUnknown::Release 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 parameters:•Verify that ppVolume is not NULL.The server MUST perform the following:[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011269 / 360
