NAME
libMPAPI, libmpapi - Common Multipath Management library
SYNOPSIS
cc [ flag... ] file... -lMPAPI [ library... ]
#include <mpapi.h>
#include <mpapi-sun.h>
DESCRIPTION
The functions in this library allow a management application to admin‐
ister the multipath devices and associated resources through standard
interfaces, independent of a vendor-unique multipathing solution.
INTERFACES
The shared object libMPAPI.so.1 provides the public interfaces defined
below. See intro(3) for additional information on shared object inter‐
faces.

USAGE
Client applications link with the Common Library (using -lMPAPI) to
access the interfaces. The Common Library dynamically loads an individ‐
ual vendor-provided plugin library that is available through MP_Regis‐
terPlugin(3MPAPI) on the host system.
Using libMPAPI involves the following steps:
1. Optionally calling MP_GetLibraryProperties() to retrieve the
properties of the Common Library.
2. Calling MP_GetPluginOidList() to retrieve the registered
plugin libraries.
3. Optionally calling MP_GetPluginProperties() to retrieve the
properties of the plugin library.
4. Retrieve discovery information and property information on
multipath devices and associated resources by calling the
following:
o MP_GetAssociatedPathOidList()
o MP_GetAssociatedTPGOidList()
o MP_GetDeviceProductOidList()
o MP_GetDeviceProductProperties()
o MP_GetInitiatorPortOidList()
o MP_GetInitiatorPortProperties()
o MP_GetMPLuOidListFromTPG()
o MP_GetMPLogicalUnitProperties()
o MP_GetMultipathLus()
o MP_GetPathLogicalUnitProperties()
o MP_GetProprietaryLoadBalanceOidList()
o MP_GetProprietaryLoadBalanceProperties()
o MP_GetTargetPortGroupProperties()
o MP_GetTargetPortOidList()
o MP_GetTargetPortProperties()
5. Register and deregister for property and visibility changes
on multipath devices and associated resources by calling:
o MP_RegisterForObjectPropertyChanges()
o MP_RegisterForObjectVisibilityChanges()
o MP_DeregisterForObjectPropertyChanges()
o MP_DeregisterForObjectVisibilityChanges()
6. Perform administrative operations on multipath devices and
associated resources by calling:
o MP_AssignLogicalUnitToTPG()
o MP_CancelOverridePath()
o MP_DisableAutoFailback()
o MP_DisableAutoProbing()
o MP_DisablePath()
o MP_EnableAutoFailback()
o MP_EnableAutoProbing()
o MP_EnablePath()
o MP_SetLogicalUnitLoadBalanceType()
o MP_SetOverridePath()
o MP_SetPathWeight()
o MP_SetPluginLoadBalanceType()
o MP_SetFailbackPollingRate()
o MP_SetProbingPollingRate()
o MP_SetProprietaryProperties()
o MP_SetTPGAccess()
o Sun_MP_SendScsiCmd()
ERRORS
Errors are generally returned from the underlying VSL and can include
any of the following values:
MP_STATUS_SUCCESS
This status value is returned when the requested operation is suc‐
cessfully carried out.
MP_STATUS_INVALID_PARAMETER
This status value is returned when parameters passed to an API are
detected to be invalid or inappropriate for a particular API param‐
eter. If the parameter is an object ID, this status indicates that
the object type subfield is defined in this specification, but is
not appropriate for this API
MP_STATUS_UNKNOWN_FN
This status value is returned when a client function passed into
the API is not a previously registered or known function.
MP_STATUS_FAILED
This status value is returned when the requested operation could
not be carried out.
MP_STATUS_INSUFFICIENT_MEMORY
This status value is returned when the API could [not] allocate the
memory required to complete the requested operation.
MP_STATUS_INVALID_OBJECT_TYPE
This status value is returned when an object ID includes a type
subfield that is not defined in this specification.
MP_STATUS_OBJECT_NOT_FOUND
This status value is returned when the object associated with the
ID specified in the API could not be located, or has been deleted.
Note that an invalid object type is covered by MP_STA‐
TUS_INVALID_OBJECT_TYPE so this status is limited to an invalid
object owner identifier or sequence number.
MP_STATUS_UNSUPPORTED
This status value is returned when the implementation does not sup‐
port the requested function.
MP_STATUS_FN_REPLACED
This status value is returned when a client function passed into
the API replaces a previously registered function.
MP_STATUS_ACCESS_STATE_INVALID
This status value is returned when a device processing MP_SetTPGAc‐
cess returns a status indicating that the caller is attempting to
establish an illegal combination of access states.
MP_STATUS_PATH_NONOPERATIONAL
This status is returned when communication cannot be established
with the path selected by the caller.
MP_STATUS_TRY_AGAIN
This status is returned when the plugin or driver is unable to com‐
plete the request, but might be able to complete it later.
MP_STATUS_NOT_PERMITTED
The operation is not permitted in the current configuration, but
might be permitted in other configurations.
