CIM_IRQ class

The CIM_IRQ class represents an Intel architecture interrupt request line (IRQ).

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 inherited properties. Properties are listed in alphabetic order, not MOF order.

• Properties

Properties

The CIM_IRQ class has these properties.

Availability

Data type: uint16

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.2")

Availability of the IRQ.

Other (1)

Unknown (2)

Available (3)

In Use/Not Available (4)

In Use and Available/Shareable (5)

In use and available/sharable

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64), DisplayName ("Caption")

A short textual description of the object.

This property is inherited from CIM_ManagedSystemElement.

CreationClassName

Data type: string

Access type: Read-only

Qualifiers: CIM_Key, MaxLen (256)

Name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allows all instances of the class and its subclasses to be uniquely identified.

CSCreationClassName

Data type: string

Access type: Read-only

Qualifiers: Propagated ("CIM_ComputerSystem.CreationClassName"), CIM_Key, MaxLen (256)

Scoping computer system's creation class name.

CSName

Data type: string

Access type: Read-only

Qualifiers: Propagated ("CIM_ComputerSystem.Name"), CIM_Key, MaxLen (256)

Scoping computer system's name.

Description

Data type: string

Access type: Read-only

Qualifiers: DisplayName ("Description")

A textual description of the object.

This property is inherited from CIM_ManagedSystemElement.

InstallDate

Data type: datetime

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5"), DisplayName ("Install Date")

Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.

This property is inherited from CIM_ManagedSystemElement.

IRQNumber

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.1"), key

Part of the object's key value, IRQ number.

Name

Data type: string

Access type: Read-only

Qualifiers: DisplayName ("Name")

Label by which the object is known. When subclassed, this property can be overridden to be a key property.

This property is inherited from CIM_ManagedSystemElement.

Shareable

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.4")

If TRUE, the IRQ can be shared.

Status

Data type: string

Access type: Read-only

Qualifiers: MaxLen (10), DisplayName ("Status")

String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).

Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.

This property is inherited from CIM_ManagedSystemElement.

Values include the following:

OK ("OK")

Error ("Error")

Degraded ("Degraded")

Unknown ("Unknown")

Pred Fail ("Pred Fail")

Starting ("Starting")

Stopping ("Stopping")

Service ("Service")

Stressed ("Stressed")

NonRecover ("NonRecover")

No Contact ("No Contact")

Lost Comm ("Lost Comm")

TriggerLevel

Data type: uint16

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|System Resource IRQ Info|001.3")

Indicates whether the interruption is triggered by the hardware signal going high or low.

Other (1)

Unknown (2)

Active Low (3)

Active High (4)

TriggerType

Data type: uint16

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|IRQ|001.3", "MIF.DMTF|System Resource IRQ Info|001.2")

Type of interruption that can occur.

Other (1)

Unknown (2)

Level (3)

Edge (4)

Remarks

The CIM_IRQ class is derived from CIM_SystemResource.WMI does not implement this class. See Win32 Classes for classes derived from CIM_IRQ.

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.
