Key |
CreationClassName

|
|
An address or other identifying information to uniquely name the LogicalDevice. |
SystemCreationClassName
|
string
|
|
The scoping System's CreationClassName. |
SystemName
|
string
|
|
The scoping System's Name. |

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. |
ErrorCleared
|
boolean
|
|
ErrorCleared is a boolean property indicating that the error reported in LastErrorCode is now cleared. |
ErrorDescription
|
string
|
|
ErrorDescription is a free-form string supplying more information about the error recorded in LastErrorCode, and information on any corrective actions that may be taken. |
IdentifyingDescriptions
|
string
|
|
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. |
LastErrorCode
|
uint32
|
|
LastErrorCode captures the last error code reported by the LogicalDevice. |
MaxQuiesceTime
|
uint64
|
|
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. |
OtherIdentifyingInfo
|
string
|
|
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
|
uint16
|
Unknown | 0 |
Not Supported | 1 |
Disabled | 2 |
Enabled | 3 |
Power Saving Modes Entered Automatically | 4 |
Power State Settable | 5 |
Power Cycling Supported | 6 |
Timed Power On Supported | 7 |
|
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. |
PowerManagementSupported
|
boolean
|
|
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 relationhip) indicates that power management is supported. |
PowerOnHours
|
uint64
|
|
The number of consecutive hours that this Device has been powered, since its last power cycle. |
StatusInfo
|
uint16
|
Other | 1 |
Unknown | 2 |
Enabled | 3 |
Disabled | 4 |
Not Applicable | 5 |
|
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), a Device can only be"enabled"or powered off. In a personal computer environment, ("Disabled") means that the Device's driver is not available in the stack. In other environments, a Device can be disabled by removing its configuration file. A disabled device is physically present in a System and consuming resources, but can not be communicated with until a load of a driver, a load of a configuration file or some other"enabling"activity has occurred. |
TotalPowerOnHours
|
uint64
|
|
The total number of hours that this Device has been powered. |
