Providers and Packs: The client invokes IVdsSwProvider::QueryPacks to obtain a list of the packsthat the provider maintains. The server responds with an IEnumVdsObject interface, whichenumerates a list of IUnknown interfaces, one for each pack. The client invokesIUnknown::QueryInterface to retrieve an IVdsPack or IVdsPack2 interface on the pack object.Packs and <strong>Disk</strong>s: The client invokes IVdsPack::Query<strong>Disk</strong>s to obtain a list of the disks in the pack.The server responds with an IEnumVdsObject interface, which enumerates a list of IUnknowninterfaces, one for each disk in the pack. The client invokes IUnknown::QueryInterface toretrieve an IVds<strong>Disk</strong>, IVds<strong>Disk</strong>2, IVds<strong>Disk</strong>3, IVdsAdvanced<strong>Disk</strong>, IVdsAdvanced<strong>Disk</strong>2,IVds<strong>Disk</strong>PartitionMF, IVds<strong>Disk</strong>PartitionMF2, IVdsCreatePartitionEx, Ivds<strong>Disk</strong>Online, orIVdsRemovable interface on the disk object.Packs and Volumes: The client invokes IVdsPack::QueryVolumes to obtain a list of the volumes inthe pack. The server responds with an IEnumVdsObject interface, which enumerates a list ofIUnknown interfaces, one for each volume in the pack. The client invokesIUnknown::QueryInterface to retrieve an IVdsVolume, IVdsVolume2, IVdsVolumeOnline, orIVdsVolumeShrink interface on the volume object.Volumes and Plexes: The client invokes IVdsVolume::QueryPlexes to obtain a list of the plexesfor a volume. The server responds with an IEnumVdsObject interface, which enumerates a list ofIUnknown interfaces, one for each plex that is associated with the volume. The client invokesIUnknown::QueryInterface to retrieve an IVdsVolumePlex interface on the plex object.Plexes and Extents: The client invokes IVdsVolumePlex::QueryExtents to obtain a list of theextents for a specified plex. The server returns a list of <strong>VDS</strong>_DISK_EXTENT structures, one foreach extent in use by the plex.Volumes and Drive Letters: The client invokes IVds<strong>Service</strong>::QueryDriveLetters to obtain a list ofdrive letters on the system. The server returns a list of <strong>VDS</strong>_DRIVE_LETTER_PROP structures;the volumeId member indicates the volume that is associated with the drive letter.Volumes and Reparse Points: For the IVdsVolume interface, the client invokesIUnknown::QueryInterface to retrieve an IVdsVolumeMF interface. The client then invokesIVdsVolumeMF::QueryReparsePoints to obtain a list of mount points on the volume. The serverreturns a list of <strong>VDS</strong>_REPARSE_POINT_PROP structures; the SourceVolumeId memberindicates the mounted volume. For example, for drive D mounted to C:\MountD, drive D is themounted volume.Volumes and Access Paths: The client invokes IUnknown::QueryInterface to retrieve anIVdsVolumeMF interface. The client then invokes IVdsVolumeMF::QueryAccessPaths to obtaina list of user mode path names for the volume. The server returns a list of drive letters and mountpoints for the volume. For drive D mounted to C:\MountD, drive D is the mounted volume andC:\MountD is the mount point.Volumes and Supported File System Formats: The client invokes IUnknown::QueryInterface toretrieve an IVdsVolumeMF2 interface. The client invokesIVdsVolumeMF2::QueryFileSystemFormatSupport to obtain a list of file systems that aresupported for the volume. The server returns a list of<strong>VDS</strong>_FILE_SYSTEM_FORMAT_SUPPORT_PROP structures, one for each file system that issupported on the volume.<strong>Disk</strong>s and Extents: The client invokes IVds<strong>Disk</strong>::QueryExtents to obtain a list of the extents for aspecified disk. The server returns a list of <strong>VDS</strong>_DISK_EXTENT structures, one for each extent onthe disk. Alternatively, the client invokes IVds<strong>Disk</strong>3::QueryFreeExtents to obtain a list of the freeextents for a specified disk. The server returns a list of <strong>VDS</strong>_DISK_FREE_EXTENT structures, onefor each extent on the disk that is associated with free space on the disk.[<strong>MS</strong>-<strong>VDS</strong>] — v20110610<strong>Virtual</strong> <strong>Disk</strong> <strong>Service</strong> (<strong>VDS</strong>) <strong>Protocol</strong> <strong>Specification</strong>Copyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011145 / 360
