Contains indicators of the current status of the element. The first value of the OperationalStatus property should contain the primary status for the element.

Note

The OperationalStatus property replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, we strongly recommend that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status, because it is a single-valued property, should also provide the primary status of the element.

This property is inherited from CIM_ManagedSystemElement.

Other (1)

Indicates an undefined state.

OK (2)

Indicates that the element functions, but requires attention. Overload and overheated are examples of Stressed states.

Predictive Failure (5)

Indicates that an element functions nominally, but predicts a failure in the near future.

Indicates that the monitoring system has information about this element, but has never been able to establish communications with it.

Lost Communication (13)

Indicates that the monitoring system has successfully contacted this element in the past, but it is currently unavailable.

Aborted (14)

Indicates that the job stopped in an unexpected way. The state and configuration of the job might require an update.

Dormant (15)

Indicates that the job is inactive.

Supporting Entity in Error (16)

Indicates that an element on which this job depends is in error. This element might be OK but cannot function because of the state of a dependent element. An example is a network service or endpoint that cannot function due to lower-layer networking problems.

Completed (17)

Indicates that the job has completed its operation. This value should be combined with either OK, Error, or Degraded to indicate to a client whether the complete operation Completed with OK and passed, or completed with Error and failed, or completed with Degraded and finished the operation, but did not complete OK or did not report an error.

Power Mode (18)

Indicates that the element has additional power model information that is contained in the associated power management service.

This property is inherited from CIM_StorageExtent.

StartingAddress

Data type: uint64

Access type: Read-only

Qualifiers: Units ("KiloBytes"), MappingStrings ("MIF.DMTF|Memory Array Mapped Addresses|001.3", "MIF.DMTF|Memory Device Mapped Addresses|001.4")

The starting address that is referenced by an application or operating system, and mapped by a memory controller for the memory object. The starting address is specified in kilobytes.

Status

Data type: string

Access type: Read-only

Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus"), MaxLen (10)

Indicates the primary status of the object.

Note

This property is deprecated. It is replaced by the OperationalStatus property. If you choose to use the Status property for backward compatibility, it should be secondary to the OperationalStatus property.

This property is inherited from CIM_ManagedSystemElement.

StatusDescriptions

Data type: string array

Access type: Read-only

Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.OperationalStatus")

Indicates descriptions of the corresponding values in the OperationalStatus array. For example, if an element in the OperationalStatus property contains the value Stopping, then the element at the same array index in this property might contain an explanation as to why an object is being stopped.

This property is inherited from CIM_ManagedSystemElement.

StatusInfo

Data type: uint16

Access type: Read-only

Qualifiers: Deprecated ("CIM_EnabledLogicalElement.EnabledState"), MappingStrings ("MIF.DMTF|Operational State|006.4")

This property is deprecated. Instead, use the CIM_PowerManagementCapabilities class.

Deprecated description: Indicates whether the logical device is enabled or in a related state.

This property is inherited from CIM_LogicalDevice.

SystemCreationClassName

Data type: string

Access type: Read-only

Qualifiers: Key, Propagated ("CIM_System.CreationClassName"), MaxLen (256)

The class name used to create an instance of the system that contains the logical device. SystemCreationClassName is combined with other key properties of this class to uniquely identify instances of this class and its subclasses.

This property is inherited from CIM_LogicalDevice.

SystemLevelAddress

Data type: boolean

Access type: Read-only

Qualifiers: Deprecated ("CIM_MemoryError.SystemLevelAddress")

true if the address information in the ErrorAddress property is a system-level address, false if it is a physical address.

SystemName

Data type: string

Access type: Read-only

Qualifiers: Key, Propagated ("CIM_System.Name"), MaxLen (256)

The name of the system that contains the logical device.

This property is inherited from CIM_LogicalDevice.

TimeOfLastStateChange

Data type: datetime

Access type: Read-only

Indicates when the element last changed state. If the state of the element has not changed and this property is populated, then it must be set to a zero interval value. If a state change was requested, but was rejected or is not yet processed, the property must not be updated.

This property is inherited from CIM_EnabledLogicalElement.

TotalPowerOnHours

Data type: uint64

Access type: Read-only

Qualifiers: Deprecated ("CIM_PoweredStatisticalData.TotalPowerOnHours"), Units ("Hours"), Counter

The total number of hours the logical device has been powered.

This property is inherited from CIM_LogicalDevice.

Volatile

Data type: boolean

Access type: Read-only

true if the memory is volatile; otherwise, false.
