MP_AssignLogicalUnitToTPG - assign a multipath logical unit to a target port group
cc [ flag… ] file… –lMPAPI [ library… ] #include <mpapi.h> MP_STATUS MP_AssignLogicalUnitToTPG(MP_OID tpgOid, MP_OID luOid);
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.
An object ID that has type MP_MULTIPATH_LOGICAL_UNIT.
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.
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.
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 .
The tpgOid or luOid owner ID or object sequence number is invalid.
The API is not supported.
The operation is successful.
