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

2.2.1.2.21 VDS_LUN_RESERVE_MODEThe VDS_LUN_RESERVE_MODE enumeration defines the sharing mode of a disk.typedef enum _VDS_LUN_RESERVE_MODE{VDS_LRM_NONE = 0x00000000,VDS_LRM_EXCLUSIVE_RW = 0x00000001,VDS_LRM_EXCLUSIVE_RO = 0x00000002,VDS_LRM_SHARED_RO = 0x00000003,VDS_LRM_SHARED_RW = 0x00000004} VDS_LUN_RESERVE_MODE;VDS_LRM_NONE: The disk has no assigned sharing mode.VDS_LRM_EXCLUSIVE_RW: The disk is reserved for exclusive access.VDS_LRM_EXCLUSIVE_RO: The disk is available for read access.VDS_LRM_SHARED_RO: The disk is available for shared read access.VDS_LRM_SHARED_RW: The disk is available for shared read/write access.2.2.1.2.22 VDS_VOLUME_STATUSThe VDS_VOLUME_STATUS enumeration defines the set of object status values for a volume.typedef enum _VDS_VOLUME_STATUS{VDS_VS_UNKNOWN = 0x00000000,VDS_VS_ONLINE = 0x00000001,VDS_VS_NO_MEDIA = 0x00000003,VDS_VS_OFFLINE = 0x00000004,VDS_VS_FAILED = 0x00000005} VDS_VOLUME_STATUS;VDS_VS_UNKNOWN: The status of the volume is unknown.VDS_VS_ONLINE: The volume is available.VDS_VS_NO_MEDIA: The volume belongs to a removable media device, such as a CD-ROM orDVD-ROM drive, but the device does not currently have media in the drive.VDS_VS_OFFLINE: When this status is set, it (1) indicates that no path names for the volumeare available for use by applications, and (2) prevents READ and READ|WRITE handles to thevolume device being opened. When a volume transitions to this state, calls to open a newhandle against the volume device fail, but any in-progress I/O against the volume willcomplete before all I/O to the volume is stopped.VDS_VS_FAILED: The volume is unavailable.2.2.1.2.23 VDS_VOLUME_FLAGThe VDS_VOLUME_FLAG enumeration defines the set of valid flags for a volume object.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201140 / 360
