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.

Members

The CIM_SCSIInterface class has these types of members:

• Properties

Properties

The CIM_SCSIInterface class has these properties.

AccessState

Data type: uint16

Access type: Read-only

Indicates whether the controller is actively commanding or accessing the device. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.

This property is inherited from CIM_ControlledBy.

Unknown (0)

Active (1)

Inactive (2)

Antecedent

Data type: CIM_SCSIController

Access type: Read-only

Qualifiers: Override ("Antecedent")

A CIM_SCSIController that describes the SCSI controller.

Dependent

Data type: CIM_LogicalDevice

Access type: Read-only

Qualifiers: Override ("Dependent")

A CIM_LogicalDevice that describes the logical device.

NegotiatedDataWidth

Data type: uint32

Access type: Read-only

Qualifiers: Units ("bits")

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, the property should be set to 0 (zero).

This property is inherited from CIM_DeviceConnection.

NegotiatedSpeed

Data type: uint64

Access type: Read-only

Qualifiers: Units ("bits per second")

When several bus or connection speeds are possible, this property defines the one being used 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, the property should be set to 0 (zero).

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

This property is inherited from CIM_DeviceConnection.

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 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.
