- set a load balancing policy
cc [ flag… ] file… -lMPAPI [ library… ] #include <mpapi.h> MP_STATUS MP_SetLogicalUnitLoadBalanceType(MP_OID logicalUnitoid, MP_LOAD_BALANCE_TYPE loadBalance);
The object ID of the multipath logical unit.
The desired load balance policy for the specified logical unit.
The MP_SetLogicalUnitLoadBalanceType() function sets the multipath logical unit's load balancing policy. The value must correspond to one of the supported values in MP_PLUGIN_PROPERTIES.SupportedLogicalUnitLoadBalanceTypes.
The logicalUnitOid does not specify any valid object type. This is most likely to happen if an uninitialized object ID is passed to the API.
The loadBalance is invalid or logicalUnitOid has a type subfield other than MP_OBJECT_TYPE_MULTIPATH_LU.
The logicalUnitOid owner ID or object sequence number is invalid.
The operation is successful.
The specified loadBalance type cannot be handled by the plugin. One possible reason for this is a request to set MP_LOAD_BALANCE_TYPE_PRODUCT when the specified logical unit has no corresponding MP_DEVICE_PRODUCT_PROPERTIES instance (i.e., the plugin does not have a product-specific load balance algorithm for the LU product).
The implementation does not support the API.
