MP_AssignLogicalUnitToTPG(3MPAPI)		   Common Multipath Management Library Functions		 MP_AssignLogicalUnitToTPG(3MPAPI)

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.
