MP_SETPATHWEIGHT(3MPAPI) Common Multipath Management Library Functions
MP_SetPathWeight - set the weight of a path
cc [ flag... ] file... -lMPAPI [ library... ]
#include <mpapi.h>
MP_STATUS MP_SetPathWeight(MP_OID pathOid, MP_UINT32 weight);
pathOid
The object ID of the path logical unit.
weight
A weight that will be assigned to the path logical unit.
The MP_SetPathWeight() function sets the weight to be assigned to a
particular path.
MP_STATUS_INVALID_OBJECT_TYPE
The pathOid 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 pathOid ownerID or object sequence number is invalid.
MP_STATUS_INVALID_PARAMETER
The pathOid has a type subfield other than
MP_OBJECT_TYPE_PATH_LU, or when the weight parameter is greater
than the plugin's maximum weight property.
MP_STATUS_SUCCESS
The operation is successful.
MP_STATUS_FAILED
The operation failed.
MP_STATUS_UNSUPPORTED
The driver does not support setting path weight.
