Class CIM_ProtocolControllerForUnit
extends CIM_ProtocolControllerForDevice

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.

AccessStateuint16
DescriptionstringThe 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.
