The VDS_PATH_STATUS enumeration defines the set of status values for a path to a storage device.

 typedef  enum _VDS_PATH_STATUS
 {
   VDS_MPS_UNKNOWN = 0x00000000,
   VDS_MPS_ONLINE = 0x00000001,
   VDS_MPS_FAILED = 0x00000005,
   VDS_MPS_STANDBY = 0x00000007
 } VDS_PATH_STATUS;

VDS_MPS_UNKNOWN:  The status of the path is unknown.

VDS_MPS_ONLINE:  The path is available.

VDS_MPS_FAILED:  The path is unavailable.

VDS_MPS_STANDBY:  The path is on standby; it is available but will not be used unless other paths fail.
