 MP_ASSIGNLOGICALUNITTOTPG 3MPAPI "Feb 15, 2006"
 NAME
MP_AssignLogicalUnitToTPG - assign a multipath logical unit to a target port
group

 SYNOPSIS


cc [ flag.\|.\|. ] file.\|.\|. -lMPAPI [ library.\|.\|. ]
#include <mpapi.h>

MP_STATUS MP_AssignLogicalUnitToTPG(MP_OID tpgOid, MP_OID luOid);




 PARAMETERS
tpgOid


An object ID that has type MP_TARGET_PORT_GROUP. The target port group
currently in active access state that the administrator would like the LU
assigned to.



luOid


An object ID that has type MP_MULTIPATH_LOGICAL_UNIT.




 DESCRIPTION

The MP_AssignLogicalUnitToTPG() function assigns a multipath logical unit
to a target port group.


Calling this function is valid only if the field supportsLuAssignment in
the data structure TARGET_PORT_GROUP_PROPERTIES is true. This capability
is not defined in SCSI standards. In some cases, devices support this
capability through non-SCSI interfaces (such as SMI-S or SNMP). This method is
only used when devices support this capability through vendor-specific means.


At any given time, each LU will typically be associated with two target port
groups, one in active state and one in standby state. The result of this API
will be that the LU associations change to a different pair of target port
groups. The caller should specify the object ID of the desired target port
group in active access state.

 RETURN VALUES
MP_STATUS_INVALID_OBJECT_TYPE


The tpgOid or luOid parameter 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_INVALID_PARAMETER


The tpgOid parameter has a type subfield other than
MP_OBJECT_TYPE_TARGET_PORT_GROUP or luOid has a type subfield other
than MP_OBJECT_TYPE_MULTIPATH_LU.



MP_STATUS_OBJECT_NOT_FOUND


The tpgOid or luOid owner ID or object sequence number is invalid.



MP_STATUS_UNSUPPORTED


The API is not supported.



MP_STATUS_SUCCESS


The operation is successful.
