Msvm_ProtocolControllerForUnit class
This association indicates that a subclass of logical device (for example a storage volume) is connected through a specific protocol controller. In many situations (for example storage LUN masking), there may be many of these associations used to relate to different objects. Therefore, subclasses have been defined to optimize enumeration of the associations.
The following syntax is simplified Managed Object Format (MOF) code, and it includes all of the inherited properties.

Properties
The Msvm_ProtocolControllerForUnit class has these properties.
-
AccessPriority
-
-
Data type: uint16
-
Access type: Read-only
The priority given to accesses of the device through this controller. The highest priority path will have the lowest value for this parameter. This class is inherited from CIM_ProtocolControllerForDevice.
-
-
AccessState
-
-
Data type: uint16
-
Access type: Read-only
Indicates whether the controller is actively commanding or accessing the device (2) or not (3). Also, the value, 0 (Unknown), can be defined. This information is necessary when a logical device can be commanded by, or accessed through, multiple protocol controllers. This class is inherited from CIM_ProtocolControllerForDevice.
-
Unknown (0)
-
Active (2)
-
Inactive (3 )
-
-
Antecedent
-
-
Data type: CIM_ProtocolController
-
Access type: Read-only
The protocol controller. This class is inherited from CIM_Dependency.
-
-
Dependent
-
-
Data type: CIM_LogicalDevice
-
Access type: Read-only
The controlled device. This class is inherited from CIM_Dependency.
-
-
DeviceAccess
-
-
Data type: uint16
-
Access type: Read-only
The access rights granted to the device through this controller. This class is inherited from CIM_ProtocolControllerForUnit.
Value Meaning - 0
Unknown - 2
Read/Write - 3
Read-only - 4
No access. - 5..15999
DMTF Reserved - 16000..
Vendor reserved -
-
DeviceNumber
-
-
Data type: string
-
Access type: Read-only
The address of the associated device in the context of the antecedent controller. This class is inherited from CIM_ProtocolControllerForDevice.
