CIM_LogicalDevice class
An abstraction or emulation of a hardware entity, that may or may not be Realized in physical hardware. Any characteristics of a LogicalDevice that are used to manage its operation or configuration are contained in, or associated with, the LogicalDevice object. Examples of the operational properties of a Printer would be paper sizes supported, or detected errors. Examples of the configuration properties of a Sensor Device would be threshold settings. Various configurations could exist for a LogicalDevice. These configurations could be contained in Setting objects and associated with the LogicalDevice.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Members
The CIM_LogicalDevice class has these types of members:
Methods
The CIM_LogicalDevice class has these methods.
| Method | Description |
|---|---|
| EnableDevice | The EnableDevice method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. Requests that the LogicalDevice be enabled ("Enabled" input parameter = TRUE) or disabled (= FALSE). If successful, the Device's StatusInfo/EnabledState properties should reflect the desired state (enabled/disabled). Note that this method's function overlaps with the RequestedState property. RequestedState was added to the model to maintain a record (i.e., a persisted value) of the last state request. Invoking the EnableDevice method should set the RequestedState property appropriately. The return code should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. |
| OnlineDevice | The OnlineDevice method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. Requests that the LogicalDevice be brought online ("Online" input parameter = TRUE) or taken offline (= FALSE). "Online" indicates that the Device is ready to accept requests, and is operational and fully functioning. In this case, the Device's Availability property would be set to a value of 3 ("Running/Full Power"). "Offline" indicates that a Device is powered up and operational, but not processing functional requests. In an offline state, a Device may be capable of running diagnostics or generating operational alerts. For example, when the "Offline" button is pushed on a Printer, the Device is no longer available to process print jobs, but could be available for diagnostics or maintenance. If this method is successful, the Device's Availability and AdditionalAvailability properties should reflect the updated status. If a failure occurs trying to bring the Device online or offline, it should remain in its current state. IE, the request, if unsuccessful, should not leave the Device in an indeterminate state. When bringing a Device back "Online", from an "Offline" mode, the Device should be restored to its last "Online" state, if at all possible. Only a Device that has an EnabledState/StatusInfo of "Enabled" and has been configured can be brought online or taken offline. OnlineDevice should return 0 if successful, 1 if the request is not supported at all, 2 if the request is not supported due to the current state of the Device, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. Note that this method's function overlaps with the RequestedState property. RequestedState was added to the model to maintain a record (i.e., a persisted value) of the last state request. Invoking the OnlineDevice method should set the RequestedState property appropriately. |
| QuiesceDevice | The QuiesceDevice method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. Requests that the LogicalDevice cleanly cease all current activity ("Quiesce" input parameter = TRUE) or resume activity (= FALSE). For this method to quiesce a Device, that Device should have an Availability (or Additional Availability) of "Running/Full Power" (value=3) and an EnabledStatus/StatusInfo of "Enabled". For example, if quiesced, a Device may then be offlined for diagnostics, or disabled for power off and hot swap. For the method to "unquiesce" a Device, that Device should have an Availability (or AdditionalAvailability) of "Quiesced" (value=21) and an EnabledStatus/StatusInfo of "Enabled". In this case, the Device would be returned to an "Enabled" and "Running/Full Power" status. The method's return code should indicate the success or failure of the quiesce. It should return 0 if successful, 1 if the request is not supported at all, 2 if the request is not supported due to the current state of the Device, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. |
| RequestStateChange | Requests that the state of the element be changed to the value specified in the RequestedState parameter. When the requested state change takes place, the EnabledState and RequestedState of the element will be the same. Invoking the RequestStateChange method multiple times could result in earlier requests being overwritten or lost. If 0 is returned, then the task completed successfully and the use of ConcreteJob was not required. If 4096 (0x1000) is returned, then the task will take some time to complete, ConcreteJob will be created, and its reference returned in the output parameter Job. Any other return code indicates an error condition. This method is inherited from CIM_EnabledLogicalElement. |
| Reset | Requests a reset of the LogicalDevice. The return value should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. |
| RestoreProperties | Requests that the Device re-establish its configuration, setup and/or state information from a backing store. The intent is to capture this information at an earlier time (via the SaveProperties method), and use it to return a Device to this earlier "condition". This method may not be supported by all Devices. The method should return 0 if successful, 1 if the request is not supported, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. |
| SaveProperties | Requests that the Device capture its current configuration, setup and/or state information in a backing store. The goal would be to use this information at a later time (via the RestoreProperties method), to return a Device to its present "condition". This method may not be supported by all Devices. The method should return 0 if successful, 1 if the request is not supported, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. |
| SetPowerState | Sets the power state of the Device. The use of this method has been deprecated. Instead, use the SetPowerState method in the associated PowerManagementService class. |
Properties
The CIM_LogicalDevice class has these properties.
-
AdditionalAvailability
-
-
Data type: uint16 array
-
Access type: Read-only
-
Qualifiers: ModelCorrespondence ("CIM_LogicalDevice.Availability")
Additional availability and status of the Device, beyond that specified in the Availability property. The Availability property denotes the primary status and availability of the Device. In some cases, this will not be sufficient to denote the complete status of the Device. In those cases, the AdditionalAvailability property can be used to provide further information. For example, a Device's primary Availability may be "Off line" (value=8), but it may also be in a low power state (AdditonalAvailability value=14), or the Device could be running Diagnostics (AdditionalAvailability value=5, "In Test").

The primary availability and status of the Device. (Additional status information can be specified using the Additional Availability array property.) For example, the Availability property indicates that the Device is running and has full power (value=3), or is in a warning (4), test (5), degraded (10) or power save state (values 13-15 and 17). Regarding the Power Save states, these are defined as follows: Value 13 ("Power Save - Unknown") indicates that the Device is known to be in a power save mode, but its exact status in this mode is unknown; 14 ("Power Save - Low Power Mode") indicates that the Device is in a power save state but still functioning, and may exhibit degraded performance; 15 ("Power Save - Standby") describes that the Device is not functioning but could be brought to full power 'quickly'; and value 17 ("Power Save - Warning") indicates that the Device is in a warning state, though also in a power save mode.

Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.OtherEnabledState")
EnabledState is an integer enumeration that indicates the enabled and disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down (value=4) and starting (value=10) are transient states between enabled and disabled. The following text briefly summarizes the various enabled and disabled states: Enabled (2) indicates that the element is or could be executing commands, will process any queued commands, and queues new requests. Disabled (3) indicates that the element will not execute commands and will drop any new requests. Shutting Down (4) indicates that the element is in the process of going to a Disabled state. Not Applicable (5) indicates the element does not support being enabled or disabled. Enabled but Offline (6) indicates that the element might be completing commands, and will drop any new requests. Test (7) indicates that the element is in a test state. Deferred (8) indicates that the element might be completing commands, but will queue any new requests. Quiesce (9) indicates that the element is enabled but in a restricted mode. Starting (10) indicates that the element is in the process of going to an Enabled state. New requests are queued.

HealthState
-
Data type: uint16
-
Access type: Read-only
Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its sub-components.
This property is inherited from CIM_ManagedSystemElement.
The following values have been defined:
Unknown (0)
The implementation cannot report on HealthState at this time.
OK (5)
The element is fully functional and is operating within normal operational parameters and without error.
Degraded/Warning (10)
The element is in working order and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors
Minor failure (15)
All functionality is available but some might be degraded.
Major failure (20)
The element is failing. It is possible that some or all of the functionality of this component is degraded or not working.
Critical failure (25)
The element is non-functional and recovery might not be possible.
Non-recoverable error (30)
The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost.
DMTF Reserved
DMTF has reserved the unused portion of the continuum for additional HealthStates in the future.
IdentifyingDescriptions
-
Data type: string array
-
Access type: Read-only
-
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_LogicalDevice.OtherIdentifyingInfo")
An array of free-form strings providing explanations and details behind the entries in the OtherIdentifyingInfo array. Note, each entry of this array is related to the entry in OtherIdentifyingInfo that is located at the same index.
InstallDate
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")
Indicates when the object was installed. The lack of a value does not indicate that the object is not installed.
This property is inherited from CIM_ManagedSystemElement.
LastErrorCode
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: Deprecated ("CIM_DeviceErrorData.LastErrorCode")
LastErrorCode captures the last error code reported by the LogicalDevice.
MaxQuiesceTime
-
Data type: uint64
-
Access type: Read-only
-
Qualifiers: Deprecated ("No value"), Units ("MilliSeconds")
The MaxQuiesceTime property has been deprecated. When evaluating the use of Quiesce, it was determine that this single property is not adequate for describing when a device will automatically exit a quiescent state. In fact, the most likely scenario for a device to exit a quiescent state was determined to be based on the number of outstanding requests queued rather than on a maximum time. This will be re-evaluated and repositioned later. Maximum time in milliseconds, that a Device can run in a "Quiesced" state. A Device's state is defined in its Availability and AdditionalAvailability properties, where "Quiesced" is conveyed by the value 21. What occurs at the end of the time limit is device-specific. The Device may unquiesce, may offline or take other action. A value of 0 indicates that a Device can remain quiesced indefinitely.
Name
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (1024)
The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.
This property is inherited from CIM_ManagedSystemElement.
OperationalStatus
-
Data type: uint16 array
-
Access type: Read-only
-
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.StatusDescriptions")
Contains indicators of the current status of the element. The first value of OperationalStatus should contain the primary status for the element.
Note
OperationalStatus replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, Microsoft strongly recommends that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status (because it is single-valued) should also provide the primary status of the element.
This property is inherited from CIM_ManagedSystemElement.
The following values have been defined:
Unknown (0)
Indicates the implementation cannot report on OperationalStatus at this time.
Other (1)
Indicates an undefined state.
OK (2)
Indicates full functionality without errors.
Degraded (3)
Indicates the element is working and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors
Stressed (4)
Indicates that the element is functioning, but needs attention. Overload and overheated are examples of Stressed states.
Predictive Failure (5)
Indicates that an element is functioning nominally but predicting a failure in the near future.
Error (6)
Indicates that an error has occurred.
Non-Recoverable Error (7)
A non-recoverable error has occurred.
Starting (8)
The job is starting.
Stopping (9)
The job is stopping.
Stopped (10)
The element has been intentionally stopped.
In Service (11)
Indicates the element is being configured, maintained, cleaned, or otherwise administered.
No Contact (12)
Indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it.
Lost Communication (13)
Indicates that the job is known to exist and has been contacted successfully in the past, but is currently unreachable.
Aborted (14)
Indicates the job stopped in an unexpected way. The state and configuration of the job might need to be updated.
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 may be OK but is unable to 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, ErrorError, or Degraded so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error).
Power Mode (18)
"Power Mode" indicates that the element has additional power model information contained in the associated PowerManagementService association.
DMTF Reserved
DMTF has reserved this portion of the range for additional OperationalStatus values in the future.
Vendor Reserved
Microsoft has reserved the unused portion of the range for additional OperationalStatus values in the future.
OtherEnabledState
-
Data type: string
-
Access type: Read-only
-
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")
A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ("Other"). This property must be set to null when EnabledState is any value other than 1.
This property is inherited from CIM_EnabledLogicalElement.
OtherIdentifyingInfo
-
Data type: string array
-
Access type: Read-only
-
Qualifiers: ArrayType ("Indexed"), MaxLen (256), ModelCorrespondence ("CIM_LogicalDevice.IdentifyingDescriptions")
OtherIdentifyingInfo captures additional data, beyond DeviceID information, that could be used to identify a LogicalDevice. One example would be to hold the Operating System's user friendly name for the Device in this property.
PowerManagementCapabilities
-
Data type: uint16 array
-
Access type: Read-only
-
Qualifiers: Deprecated ("CIM_PowerManagementCapabilities.PowerCapabilities")
An enumerated array describing the power management capabilities of the Device. The use of this property has been deprecated. Instead, the PowerCapabilites property in an associated PowerManagementCapabilities class should be used.

Access type: Read-only
-
Qualifiers: Deprecated ("CIM_PowerManagementCapabilities")
Boolean indicating that the Device can be power managed. The use of this property has been deprecated. Instead, the existence of an associated PowerManagementCapabilities class (associated using the ElementCapabilities relationship) indicates that power management is supported.
PowerOnHours
-
Data type: uint64
-
Access type: Read-only
-
Qualifiers: Units ("Hours"), Counter
The number of consecutive hours that this Device has been powered, since its last power cycle.
RequestedState
-
Data type: uint16
-
Access type: Read-only
-
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")
RequestedState is an integer enumeration that indicates the last requested or desired state for the element. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. Note that when EnabledState is set to 5 ("Not Applicable"), then this property has no meaning. By default, the RequestedState of the element is 5 ("No Change"). Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration. Offline (6) indicates that the element has been requested to transition to the Enabled but Offline EnabledState. It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are "Reboot" (10) and "Reset" (11). Reboot refers to doing a "Shut Down" and then moving to an "Enabled" state. Reset indicates that the element is first "Disabled" and then "Enabled". The distinction between requesting "Shut Down" and "Disabled" should also be noted. Shut Down requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests. This property is set as the result of a method invocation (such as Start or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code. A particular instance of EnabledLogicalElement might not support RequestedStateChange. If this occurs, the value 12 ("Not Applicable") is used.
This property is inherited from CIM_EnabledLogicalElement.

StatusInfo
-
Data type: uint16
-
Access type: Read-only

Qualifiers: Deprecated ("CIM_EnabledLogicalElement.EnabledState"), MappingStrings ("MIF.DMTF|Operational State|006.4")
The StatusInfo property indicates whether the Logical Device is in an enabled (value = 3), disabled (value = 4) or some other (1) or unknown (2) state. If this property does not apply to the LogicalDevice, the value, 5 ("Not Applicable"), should be used. StatusInfo has been deprecated in lieu of a more clearly named property with additional enumerated values (EnabledState), that is inherited from ManagedSystemElement. If a Device is ("Enabled")(value=3), it has been powered up, and is configured and operational. The Device may or may not be functionally active, depending on whether its Availability (or AdditionalAvailability) indicate that it is ("Running/Full Power")(value=3) or ("Off line") (value=8). In an enabled but offline mode, a Device may be performing out-of-band requests, such as running Diagnostics. If ("Disabled") StatusInfo value=4
