If possible, You can try rebooting the switch & rescan the disks; followed by restarting the multipath deamon (or alternatively, the server itself.)

NAME
MP_GetPathLogicalUnitProperties - get the specified path properties SYNOPSIS
cc [ flag... ] file... -lMPAPI [ library... ] #include <mpapi.h> MP_STATUS MP_GetPathLogicalUnitProperties(MP_OID oid, MP_PATH_LOGICAL_UNIT_PROPERTIES *pProps); PARAMETERS
oid The object ID of the logical unit path. pProps A pointer to an object ID that has type MP_PATH_LOGICAL_UNIT_PROPERTIES structure allocated by the caller. With a successful return, this structure contains the properties of the path specified by oid. DESCRIPTION
The MP_GetPathLogicalUnitProperties() function gets the properties of the specified path. RETURN VALUES
MP_STATUS_INVALID_PARAMETER The pProps is null or specifies a memory area to which data cannot be written, or when the oid has a type subfield other than MP_OBJECT_TYPE_PATH_LU. MP_STATUS_INVALID_OBJECT_TYPE The oid does not specify any valid object type. This is most likely to happen if an uninitialized object ID is passed to the API. MP_STATUS_OBJECT_NOT_FOUND The oid owner ID or object sequence number is invalid. MP_STATUS_SUCCESS The operation is successful. ATTRIBUTES
