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

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 pVolumeProperties is not NULL.The server MUST populate the VDS_VOLUME_PROP structure that pVolumePropertiesreferences with the properties of the volume, and then return an HRESULT indicating failure orsuccess. For information on VDS_VOLUME_PROP, see section 2.2.2.13.1.1.3.4.5.2.30.2 IVdsVolume::GetPack (Opnum 4)The GetPack method retrieves the disk pack to which the volume belongs.HRESULT GetPack([out] IVdsPack** ppPack);ppPack: A pointer to an IVdsPack interface that, if the operation is successfully completed,receives the IVdsPack interface of the pack object to which the volume belongs. Callers MUSTrelease the interface when they are done with it.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 ppPack is not NULL.The server MUST point ppPack to an IVdsPack interface of the pack object that the volume object'spack pointer refers to. It MUST then return an HRESULT indicating failure or success.3.4.5.2.30.3 IVdsVolume::QueryPlexes (Opnum 5)The QueryPlexes method enumerates the plexes of a volume.HRESULT QueryPlexes([out] IEnumVdsObject** ppEnum);ppEnum: A pointer to an IEnumVdsObject interface that, if the operation is successfullycompleted, receives the IEnumVdsObject interface of the object that contains anenumeration of volume plex objects in the volume. Callers MUST release the interface whenthey are done with it.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, 2011236 / 360
