Constants
VDS_LPT_UNKNOWNValue: 0 This value is reserved. |
VDS_LPT_SIMPLEThe plex type is simple—it is composed of extents from exactly one drive. |
VDS_LPT_SPANThe plex type is spanned—it is composed of extents from more than one drive. |
VDS_LPT_STRIPEThe plex type is striped, which is equivalent to RAID 0. |
VDS_LPT_PARITYThe plex type is striped with parity, which accounts for RAID levels 3, 4, 5, and 6. |
VDS_LPT_RAID2The plex type is RAID level 2. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID3The plex type is RAID level 3. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID4The plex type is RAID level 4. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID5The plex type is RAID level 5. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID6The plex type is RAID level 6. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID03The plex type is RAID level 0+3. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID05The plex type is RAID level 0+5. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID10The plex type is RAID level 1+0. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID15The plex type is RAID level 1+5. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID30The plex type is RAID level 3+0. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID50The plex type is RAID level 5+0. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID53The plex type is RAID level 5+3. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
VDS_LPT_RAID60The plex type is RAID level 6+0. Windows Server 2008, Windows Vista and Windows Server 2003: This value is not supported. |
Remarks
The VDS_LUN_PLEX_PROP structure includes a VDS_LUN_PLEX_TYPE value as a member to indicate the existing plex type.
If your application encounters a VDS_HWPROVIDER_TYPE value that it does not recognize, it should display the provider type as unknown. It should not attempt to map the unrecognized provider type to another provider type.
Note Additional constants might be added to the VDS_LUN_PLEX_TYPE enumeration in future Windows versions. For this reason, your application must be designed to gracefully handle an unrecognized VDS_LUN_PLEX_TYPE enumeration constant.
