CreationClassName

Data type: string

Access type: Read-only

Qualifiers: Key, MaxLen (256)

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

DeviceID

Data type: string

Access type: Read-only

Qualifiers: Key, MaxLen (64)

A unique identifier of the logical device, such as the address.

ErrorCleared

Data type: boolean

Access type: Read-only

Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus")

This property is deprecated. Instead, use the OperationalStatus property from the CIM_ManagedSystemElement class.

Deprecated description: Indicates whether an error reported by the LastErrorCode property is cleared.

ErrorDescription

Data type: string

Access type: Read-only

Qualifiers: Deprecated ("CIM_DeviceErrorData.ErrorDescription")

This property is deprecated. Instead, use the ErrorDescription property from the CIM_DeviceErrorData class.

Deprecated description: Additional information about the error reported by the LastErrorCode property.

IdentifyingDescriptions

Data type: string array

Access type: Read-only

Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_LogicalDevice.OtherIdentifyingInfo")

An array of strings that describe the OtherIdentifyingInfo array items of the same index.

LastErrorCode

Data type: uint32

Access type: Read-only

Qualifiers: Deprecated ("CIM_DeviceErrorData.LastErrorCode")

This property is deprecated. Instead, we use the LastErrorCode property from theCIM_DeviceErrorData class.

Deprecated description: The last error code reported by the logical device.

MaxQuiesceTime

Data type: uint64

Access type: Read-only

Qualifiers: Deprecated ("No value"), Units ("MilliSeconds")

This property is deprecated and should not be used.

Deprecated description: The maximum time in milliseconds, that a device can remain in a temporarily disabled state (Availability and AdditionalAvailability properties set to "21" quiescent ). A value of "0" indicates that the logical device can remain in a temporarily disabled state indefinitely.

OtherIdentifyingInfo

Data type: string array

Access type: Read-only

Qualifiers: ArrayType ("Indexed"), MaxLen (256), ModelCorrespondence ("CIM_LogicalDevice.IdentifyingDescriptions")

Information that identifies the logical device, other than DeviceID.

PowerManagementCapabilities

Data type: uint16 array

Access type: Read-only

Qualifiers: Deprecated ("CIM_PowerManagementCapabilities.PowerCapabilities")

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

Deprecated description: An array that contains the power management capabilities of the device.

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)

PowerManagementSupported

Data type: boolean

Access type: Read-only

Qualifiers: Deprecated ("CIM_PowerManagementCapabilities")

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

Deprecated description: true if the logical device can be power managed; otherwise, false.

PowerOnHours

Data type: uint64

Access type: Read-only

Qualifiers: Units ("Hours"), Counter

The number of consecutive hours the logical device has been powered, since its last power cycle.

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.

Other (1)

Unknown (2)

Enabled (3)

Disabled (4)

Not Applicable (5)

SystemCreationClassName

Data type: string

Access type: Read-only

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

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.

SystemName

Data type: string

Access type: Read-only

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

The name of the system that contains the logical device.

TotalPowerOnHours

Data type: uint64

Access type: Read-only

Qualifiers: Units ("Hours"), Counter

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