VDS_SERVICE_FLAG enumeration (vds.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]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

Syntax

typedef enum _VDS_SERVICE_FLAG {
  VDS_SVF_SUPPORT_DYNAMIC = 0x1,
  VDS_SVF_SUPPORT_FAULT_TOLERANT = 0x2,
  VDS_SVF_SUPPORT_GPT = 0x4,
  VDS_SVF_SUPPORT_DYNAMIC_1394 = 0x8,
  VDS_SVF_CLUSTER_SERVICE_CONFIGURED = 0x10,
  VDS_SVF_AUTO_MOUNT_OFF = 0x20,
  VDS_SVF_OS_UNINSTALL_VALID = 0x40,
  VDS_SVF_EFI = 0x80,
  VDS_SVF_SUPPORT_MIRROR = 0x100L,
  VDS_SVF_SUPPORT_RAID5 = 0x200L,
  VDS_SVF_SUPPORT_REFS = 0x400L
} VDS_SERVICE_FLAG;

Constants

 
VDS_SVF_SUPPORT_DYNAMIC
Value: 0x1
If set, the service supports dynamic disks.
VDS_SVF_SUPPORT_FAULT_TOLERANT
Value: 0x2
If set, the service supports fault-tolerant volumes.
VDS_SVF_SUPPORT_GPT
Value: 0x4
If set, the service supports GPT disks.
VDS_SVF_SUPPORT_DYNAMIC_1394
Value: 0x8
If set, the service supports dynamic 1394 disks.
VDS_SVF_CLUSTER_SERVICE_CONFIGURED
Value: 0x10
If set, the host has the cluster service installed and configured, but not necessarily running.
VDS_SVF_AUTO_MOUNT_OFF
Value: 0x20
If set, the auto-mount operation is turned off for the computer to prevent the operating system from
automatically mounting new partitions.

Note  Beginning with Windows 8 and Windows Server 2012, this flag is deprecated. Instead, use the VDS_SAN_POLICY enumeration to control default disk mounting behavior.

 
VDS_SVF_OS_UNINSTALL_VALID
Value: 0x40
If set, configuration changes to VDS have occurred. After a successful installation, the uninstall
operation is valid only if the configuration changes.
VDS_SVF_EFI
Value: 0x80
If set, the machine boots from an EFI partition on a GPT disk.

Windows Server 2003:  This flag is not supported before Windows Server 2003 with SP1.
VDS_SVF_SUPPORT_MIRROR
Value: 0x100L
The service supports mirrored volumes.

Windows Server 2008, Windows Vista and Windows Server 2003:  Not supported.
VDS_SVF_SUPPORT_RAID5
Value: 0x200L
The service supports RAID-5 volumes.

Windows Server 2008, Windows Vista and Windows Server 2003:  Not supported.
VDS_SVF_SUPPORT_REFS
Value: 0x400L

Remarks

This enumeration provides the values for the ulFlags member of the VDS_SERVICE_PROP structure. The IVdsService::SetFlags method passes the value as an argument to set the VDS_SVF_AUTO_MOUNT_OFF flag.

Windows Server 2003:  Many of these enumerators are specific to the Windows Server 2003 platform, which supports both 1394 and USB devices.

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