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

VIRTUAL_DISK_ACCESS_SURFACE_RW: Open the VHD for read-write surfacing (attaching)access. The caller must have (READ | WRITE) access to the virtual disk image file. If used in arequest to open a VHD that is already open, the other handles must be limited to eitherVIRTUAL_DISK_ACCESS_UNSURFACE or VIRTUAL_DISK_ACCESS_GET_INFO access;otherwise, the open request with this flag will fail. If the VHD is part of a differencing chain,the disk number for this request cannot be less than the ReadWriteDepth specified during theprior open request for that differencing chain.VIRTUAL_DISK_ACCESS_UNSURFACE: Open the VHD to allow unsurfacing (detaching) of asurfaced (attached) VHD. The caller must have (FILE_READ_ATTRIBUTES | FILE_READ_DATA)access to the virtual disk image file.VIRTUAL_DISK_ACCESS_GET_INFO: Open the VHD for retrieval of information. The callermust have READ access to the virtual disk image file.VIRTUAL_DISK_ACCESS_CREATE: Open the VHD for creation.VIRTUAL_DISK_ACCESS_METAOPS: Open the VHD to perform offline metaoperations. Forinformation on the offline metaoperations, see [MSDN-CompactVirtualDisk], [MSDN-ExpandVirtualDisk, [MSDN-MergeVirtualDisk], [MSDN-SetVirtualDiskInfo], and MSDN-VIRTDSKACCMSK]. The caller must have (READ | WRITE) access to the virtual disk image file,up to ReadWriteDepth if working with a differencing chain. If the VHD is part of a differencingchain, the backing store (host volume) is opened in read/write exclusive mode up toReadWriteDepth.VIRTUAL_DISK_ACCESS_READ: Reserved.VIRTUAL_DISK_ACCESS_ALL: Allows unrestricted access to the VHD. The caller must haveunrestricted access rights to the virtual disk image file.VIRTUAL_DISK_ACCESS_WRITABLE: Reserved.2.2.2.18.2 Structures2.2.2.18.2.1 VDS_VDISK_PROPERTIESThe VDS_VDISK_PROPERTIES structure defines the properties of a virtual disk.typedef struct _VDS_VDISK_PROPERTIES {VDS_OBJECT_ID Id;VDS_VDISK_STATE State;VIRTUAL_STORAGE_TYPE VirtualDeviceType;ULONGLONG VirtualSize;ULONGLONG PhysicalSize;[string] LPWSTR pPath;[string] LPWSTR pDeviceName;DEPENDENT_DISK_FLAG DiskFlag;BOOL bIsChild;LPWSTR pParentPath;} VDS_VDISK_PROPERTIES,*PVDS_VDISK_PROPERTIES;Id: A unique VDS-specific session identifier of the disk.State: A VDS_VDISK_STATE enumeration value that specifies the virtual disk state.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201189 / 360
