VDS_VOLUME_TYPE enumeration (vds.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Defines the set of valid types for a volume object.

Syntax

typedef enum _VDS_VOLUME_TYPE {
  VDS_VT_UNKNOWN = 0,
  VDS_VT_SIMPLE = 10,
  VDS_VT_SPAN = 11,
  VDS_VT_STRIPE = 12,
  VDS_VT_MIRROR = 13,
  VDS_VT_PARITY = 14
} VDS_VOLUME_TYPE;

Constants

VDS_VT_UNKNOWN Value: 0 The volume type is unknown.
VDS_VT_SIMPLE Value: 10 The volume type is simple—it is composed of extents from exactly one disk.
VDS_VT_SPAN Value: 11 The volume type is spanned—it is composed of extents from more than one disk.
VDS_VT_STRIPE Value: 12 The volume type is striped, which is equivalent to RAID 0.
VDS_VT_MIRROR Value: 13 The volume type is mirrored, which is equivalent to RAID 1.
VDS_VT_PARITY Value: 14 The volume type is striped with parity, which accounts for RAID levels 3, 4, 5, and 6.

Remarks

The IVdsPack::CreateVolume method passes a VDS_VOLUME_TYPE value as an argument to set a new volume type, and the VDS_VOLUME_PROP structure includes a VDS_VOLUME_TYPE value as a member to indicate the existing volume type.

Note  Additional constants might be added to the VDS_VOLUME_TYPE enumeration in future Windows versions. For this reason, your application must be designed to gracefully handle an unrecognized VDS_VOLUME_TYPE enumeration constant.
