CIM_SCSIInterface class

The CIM_SCSIInterface class represents a CIM_ControlledBy relationship that indicates which devices are accessed through a SCSI controller and the access characteristics.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

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

Syntax

class CIM_SCSIInterface : CIM_ControlledBy
{
  uint16             AccessState;
  CIM_SCSIController REF Antecedent;
  CIM_LogicalDevice  REF Dependent;
  uint32             NegotiatedDataWidth;
  uint64             NegotiatedSpeed;
  uint32             NumberOfHardResets;
  uint32             NumberOfSoftResets;
  uint32             SCSIRetries;
  uint32             SCSITimeouts;
};

Members

The CIM_SCSIInterface class has these types of members:

Properties

The CIM_SCSIInterface class has these properties.

AccessState
Data type: uint16
Access type: Read-only

When a logical device can be commanded by or accessed through multiple controllers, this property indicates whether the controller is actively commanding or accessing the device. This property is inherited from CIM_ControlledBy.

ValueMeaning

Unknown

1

Active

Antecedent
Data type: CIM_SCSIController
Access type: Read-only

Reference to the SCSI controller. This property is inherited from CIM_Dependency.

Dependent
Data type: CIM_LogicalDevice
Access type: Read-only

Reference to the logical device. This property is inherited from CIM_Dependency.

NegotiatedDataWidth
Data type: uint32
Access type: Read-only

When several bus or connection data widths are possible, this property defines the one in use between the devices. Data width is specified in bits. If data width is not negotiated, or if this information is not available or important to device management, this property should be set to 0. This property is inherited from CIM_DeviceConnection.

NegotiatedSpeed
Data type: uint64
Access type: Read-only

When several bus or connection speeds are possible, this property defines the one in use between the devices. 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, this property should be set to 0. 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. A hard reset returns the device to its initialization or boot-up state; all internal device state information and data are lost. This property is inherited from CIM_ControlledBy.

NumberOfSoftResets
Data type: uint32
Access type: Read-only

Number of soft resets issued by the controller. A soft reset does not completely clear current device state information and data. Exact semantics are dependent on the device and on the protocols and mechanisms used to communicate to it. This property is inherited from CIM_ControlledBy.

SCSIRetries
Data type: uint32
Access type: Read-only

Number of SCSI retries that have occurred since the last hard or soft reset related to the controlled device. The time of the last reset is indicated in the TimeOfDeviceReset property, inherited from the CIM_ControlledBy association.

SCSITimeouts
Data type: uint32
Access type: Read-only

Number of SCSI time-outs that occurred since last hard or soft reset related to the controlled device. The time of the last reset is indicated in the TimeOfDeviceReset property, inherited from the CIM_ControlledBy association.

Remarks

The CIM_SCSIInterface class is derived from CIM_ControlledBy.

WMI does not implement this class.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
