  VDS_PF_DYNAMIC = 0x1,
  VDS_PF_INTERNAL_HARDWARE_PROVIDER = 0x2,
  VDS_PF_ONE_DISK_ONLY_PER_PACK = 0x4,
  VDS_PF_ONE_PACK_ONLINE_ONLY = 0x8,
  VDS_PF_VOLUME_SPACE_MUST_BE_CONTIGUOUS = 0x10,
  VDS_PF_SUPPORT_DYNAMIC = 0x80000000,
  VDS_PF_SUPPORT_FAULT_TOLERANT = 0x40000000,
  VDS_PF_SUPPORT_DYNAMIC_1394 = 0x20000000,

  VDS_PF_SUPPORT_RAID5 = 0x40
} VDS_PROVIDER_FLAG;

Constants

 
VDS_PF_DYNAMIC
Value: 0x1
The provider is a dynamic provider. If this flag is set for the provider of a disk, the disk is dynamic.

simulate a pack with one disk.
VDS_PF_ONE_PACK_ONLINE_ONLY
Value: 0x8
The provider is a dynamic provider that supports online status for only one pack at a time.


Windows Server 2003:  Only applies to this release.
VDS_PF_VOLUME_SPACE_MUST_BE_CONTIGUOUS

Value: 0x40000000
If this flag is set, VDS sets the VDS_SVF_SUPPORT_FAULT_TOLERANT
flag in the VDS_SERVICE_PROP structure.
VDS_PF_SUPPORT_DYNAMIC_1394
Value: 0x20000000
If this flag is set, VDS sets the VDS_SVF_SUPPORT_DYNAMIC_1394
flag in the VDS_SERVICE_PROP structure.

Remarks

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

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