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[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]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

Syntax

typedef enum _VDS_PACK_FLAG {
  VDS_PKF_FOREIGN = 0x1,
  VDS_PKF_NOQUORUM = 0x2,
  VDS_PKF_POLICY = 0x4,
  VDS_PKF_CORRUPTED = 0x8,
  VDS_PKF_ONLINE_ERROR = 0x10
} VDS_PACK_FLAG;

Constants

 
VDS_PKF_FOREIGN
Value: 0x1
If set, an external pack is eligible for online status.
VDS_PKF_NOQUORUM
Value: 0x2
If set, a dynamic pack lacks the required quorum. A quorum is the minimum number of disks in a dynamic pack (n/2 + 1) required to enable online status. This flag prevents the caller from granting online status to the same pack on multiple computers.
VDS_PKF_POLICY
Value: 0x4
If set, the pack policy prevents online eligibility. This flag applies exclusively to packs managed by the Windows Server 2003 version of VDS, which allows only one pack at a time to maintain online status.
VDS_PKF_CORRUPTED
Value: 0x8
If set, a pack contains a disk with a corrupted database.
VDS_PKF_ONLINE_ERROR
Value: 0x10
If set, a pack with sufficient disk quorum failed to achieve online status due to an error.

Remarks

Pack flags apply to packs managed by the dynamic provider only. The provider sets these flags on offline packs to report the reason for the offline status.

This enumeration provides the values for the ulFlags member of the VDS_PACK_PROP structure.

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