VDS_DET_OEM: The extent belongs to an OEM partition.VDS_DET_ESP: The extent belongs to an Extensible Firmware Interface (EFI) systempartition.VDS_DET_MSR: The extent belongs to a Microsoft Reserved (MSR) partition.VDS_DET_LDM: The extent belongs to a disk management metadata partition.VDS_DET_UNUSABLE: The extent belongs to an area of unusable space.2.2.1.2.14 VDS_PARTITION_STYLEThe VDS_PARTITION_STYLE enumeration defines the styles of partitions.typedef enum _VDS_PARTITION_STYLE{VDS_PST_UNKNOWN = 0x00000000,VDS_PST_MBR = 0x00000001,VDS_PST_GPT = 0x00000002} VDS_PARTITION_STYLE;VDS_PST_UNKNOWN: The partition format is unknown.VDS_PST_MBR: The partition format is master boot record (MBR).VDS_PST_GPT: The partition format is GUID partitioning table (GPT).2.2.1.2.15 VDS_PARTITION_FLAGThe VDS_PARTITION_FLAG enumeration defines flags that describe partitions. A value thataccepts these flags MUST have the following flag set or MUST have the value set to 0 if the flag isnot applicable to a given partition.typedef enum _VDS_PARTITION_FLAG{VDS_PTF_SYSTEM = 0x00000001} VDS_PARTITION_FLAG;VDS_PTF_SYSTEM: Value that indicates that the partition is a system partition.2.2.1.2.16 VDS_VOLUME_TYPEThe VDS_VOLUME_TYPE enumeration defines the set of valid types for a volume object.typedef enum _VDS_VOLUME_TYPE{VDS_VT_UNKNOWN = 0x00000000,VDS_VT_SIMPLE = 0x0000000A,VDS_VT_SPAN = 0x0000000B,VDS_VT_STRIPE = 0x0000000C,VDS_VT_MIRROR = 0x0000000D,VDS_VT_PARITY = 0x0000000E} VDS_VOLUME_TYPE;[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201136 / 360
VDS_VT_UNKNOWN: The status of the volume is unknown.VDS_VT_SIMPLE: The volume type is simple: it is composed of extents from exactly one disk.VDS_VT_SPAN: The volume type is spanned: it is composed of extents from more than onedisk.VDS_VT_STRIPE: The volume type is striped, which is equivalent to RAID-0.VDS_VT_MIRROR: The volume type is mirrored, which is equivalent to RAID-1.VDS_VT_PARITY: The volume type is striped with parity, which accounts for RAID levels 3, 4,5, and 6.2.2.1.2.17 VDS_TRANSITION_STATEThe VDS_TRANSITION_STATE enumeration defines the set of valid transition state values for aVDS object.typedef enum _VDS_TRANSITION_STATE{VDS_TS_UNKNOWN = 0x00000000,VDS_TS_STABLE = 0x00000001,VDS_TS_EXTENDING = 0x00000002,VDS_TS_SHRINKING = 0x00000003,VDS_TS_RECONFIGING = 0x00000004} VDS_TRANSITION_STATE;VDS_TS_UNKNOWN: The transition state of the object cannot be determined.VDS_TS_STABLE: The object is stable. No configuration activity is currently in progress.VDS_TS_EXTENDING: The object is being extended.VDS_TS_SHRINKING: The object is being shrunk.VDS_TS_RECONFIGING: The object is being automatically reconfigured.2.2.1.2.18 VDS_FORMAT_OPTION_FLAGSThe VDS_FORMAT_OPTION_FLAGS enumeration defines the set of valid format option values.typedef enum _VDS_FORMAT_OPTION_FLAGS{VDS_ESOF_NONE = 0x00000000,VDS_ESOF_FORCE = 0x00000001,VDS_ESOF_QUICK = 0x00000002,VDS_ESOF_COMPRESSION = 0x00000004,VDS_ESOF_DUPLICATE_METADATA = 0x00000008} VDS_FORMAT_OPTION_FLAGS;VDS_ESOF_NONE: No format options are specified.VDS_ESOF_FORCE: Determines whether the format is forced, regardless of whether thevolume is in use.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201137 / 360
