MP_EnablePath(3MPAPI) Common Multipath Management Library Functions MP_EnablePath(3MPAPI)
NAME
MP_EnablePath - enable a path
SYNOPSIS
cc [ flag... ] file... -lMPAPI [ library... ]
#include <mpapi.h>
MP_STATUS MP_EnablePath(MP_OID oid);
PARAMETERS
oid The object ID of the path.

MP_STATUS_INVALID_PARAMETER
The oid has a type subfield other than MP_OBJECT_TYPE_PATH_LU.
MP_STATUS_OBJECT_NOT_FOUND
The oid owner ID or object sequence number is invalid.
MP_STATUS_UNSUPPORTED
The API is not supported.
MP_STATUS_TRY_AGAIN
The path cannot be enabled at this time.
