Win32_SCSIControllerDevice Class (Windows)

Win32_SCSIControllerDevice Class

Win32_SCSIControllerDevice Class

The Win32_SCSIControllerDevice association WMI class relates a small computer system interface (SCSI) controller and the logical device (disk drive) connected to it. Instances for this class are only provided on Windows NT or Windows 2000 or later and Windows 95 or later.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Syntax

class Win32_SCSIControllerDevice : CIM_ControlledBy
{
  uint16               AccessState;
  Win32_SCSIController REF Antecedent;
  CIM_LogicalDevice    REF Dependent;
  uint32               NegotiatedDataWidth;
  uint64               NegotiatedSpeed;
  uint32               NumberOfHardResets;
  uint32               NumberOfSoftResets;
};

Methods

The Win32_SCSIControllerDevice class does not define any methods.

Properties

The Win32_SCSIControllerDevice class defines the following properties.

AccessState

Data type: uint16
Access type: Read-only

State of the controller access to the device. The value Unknown (0) is necessary when a logical device can be commanded by, or accessed through, multiple controllers. This property is inherited from CIM_ControlledBy.

Value	Meaning
0	Unknown
1	Active
2	Inactive

Antecedent

Data type: Win32_SCSIController
Access type: Read-only
Qualifiers: Key

Reference to the Win32_SCSIController instance representing the SCSI controller associated with this device. This property is inherited from CIM_Dependency.

Dependent

Data type: CIM_LogicalDevice
Access type: Read-only
Qualifiers: Key

Reference to the CIM_LogicalDevice instance representing the logical device connected to the SCSI controller. This property is inherited from CIM_Dependency.

NegotiatedDataWidth

Data type: uint32
Access type: Read-only

Bus or connection data width in use between devices (when several are possible). Data width is specified in bits. If data width is not negotiated, or if this information is not available or important to device management, the property should be set to 0 (zero). This property is inherited from CIM_DeviceConnection.

NegotiatedSpeed

Data type: uint64
Access type: Read-only

Bus or connection speed in use between devices (when several are possible). Speed is specified in bits per second. If connection or bus speeds are not negotiated, or if this information is not available or important to device management, the property should be set to 0 (zero). This property is inherited from CIM_DeviceConnection.

For more information about using uint64 values in scripts, see Scripting in WMI.

NumberOfHardResets

Data type: uint32
Access type: Read-only

Number of hard resets issued by the controller. This property is inherited from CIM_ControlledBy.

NumberOfSoftResets

Data type: uint32
Access type: Read-only

Number of soft resets issued by the controller. This property is inherited from CIM_ControlledBy.

Remarks

The Win32_SCSIControllerDevice class is derived from CIM_ControlledBy.
