This association is used to define a relationship between a ProtocolController and an exposed Logical Unit (for example a Storage Volume or a MediaAccessDevice such as a tape drive). An example of the use of this association is SCSI, where it link the target controller and Logical Units. This subclass is provided so that an enumeration of related controllers and units can be performed without retrieving any connected ports or other controllers. | Qualifiers:Version ( "2.8.0" ) Association | Parameters (local in grey) | | Override ( "Dependent" ) CIM_LogicalDevice REF Dependent ; The logical unit (eg StorageVolume) 'behind' the ProtocolController. | Override ( "Antecedent" ) CIM_ProtocolController REF Antecedent ; The ProtocolController. | uint16 AccessPriority ; This property describes the priority given to accesses of the device through this Controller. The highest priority path will have the lowest value for this parameter. | Values { "Unknown" , "Active" , "Inactive" } ValueMap { "0" , "2" , "3" } uint16 AccessState ; The State property indicates whether the Controller is actively commanding or accessing the device (value=2) or not (value=3). Also, the value, 'Unknown' (0), can be defined. This information is necessary when a LogicalDevice can be commanded by, or accessed through, multiple ProtocolControllers. | string DeviceNumber ; Address of the associated Device in the context of the Antecedent Controller. |
