CreationClassName
|
Indicates the name of the class or the subclass used in
the creation of an instance. When used with the other key properties
of this class, this property allows all instances of this class and
its subclasses to be uniquely identified.
|
DeviceID
|
An address or other identifying information used to uniquely
name the LogicalDevice.
|
ElementName
|
A user-friendly name for the object. This property allows
each instance to define a user-friendly name in addition to its key
properties, identity data, and description information.
-
NOTE: The Name property of
ManagedSystemElement is also defined as a user-friendly name. But,
it is often subclassed to be a Key. It is not reasonable that the
same property can convey both identity and a user-friendly name, without
inconsistencies. Where Name exists and is not a Key (such as for instances
of LogicalDevice), the same information can be present in both the
Name and ElementName properties.
|
EnabledDefault
|
An enumerated value indicating a configuration of an administrator
for the Enabled State of an element.
Possible values are:
- 2 = Enabled
- 3 = Disabled
- 5 = Not Applicable
- 6 = Enabled but Offline
- 7 = No Default
- 9 = Quiesce
- .. = DMTF Reserved
- 32768..65535 = Vendor Reserved
By default, the element is
Enabled (value = 2).
|
EnabledState
|
An integer enumeration that indicates the enabled and disabled
states of an element. It can also indicate the transitions between
these requested states.
Possible values are:
- 0 = Unknown
- 1 = Other
- 2 = Enabled — Indicates that the element is or could be running
commands, will process any queued commands, and queues new requests.
- 3 = Disabled — Indicates that the element will not run commands
and will drop any new requests.
- 4 = Shutting Down — Indicates that the element is in the process
of going to a disabled state.
- 5 = Not Applicable — Indicates the element does not support being
enabled or disabled.
- 6 = Enabled but Offline — Indicates that the element may be completing
commands, and will drop any new requests.
- 7 = In Test — Indicates that the element is in a test state.
- 8 = Deferred — Indicates that the element may be completing commands,
but will queue any new requests.
- 9 = Quiesce — Indicates that the element is enabled but in a restricted
mode.
- 10 = Starting — Indicates that the element is in the process of
going to an enabled state. New requests are queued.
- 11..32767 = DMTF Reserved
- 32768..65535 = Vendor Reserved
For example, shutting down (value =
4) and starting
(value =
10) are transient states between enabled and disabled.
|
HealthState
|
Indicates the current health of the element. This attribute
expresses the health of this element but not necessarily that of its
subcomponents.
Possible values are:
- 0 = Unknown — The implementation cannot report on HealthState
at this time. DMTF has reserved the unused portion of the continuum
for additional HealthStates in the future.
- 5 = OK — The element is fully functional and is operating within
normal operational parameters and without error.
- 10 = Degraded/Warning — 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 may not be operating
at optimal performance or it may be reporting recoverable errors.
- 15 = Minor failure — All functionality is available but some may
be degraded.
- 20 = Major failure — The element is failing. It is possible that
some or all of the functionality of this component is degraded or
not working.
- 25 = Critical failure — The element is non-functional and recovery
may not be possible.
- 30 = Non-recoverable error — The element has completely failed,
and recovery is not possible. All functionality provided by this element
has been lost.
- .. = DMTF Reserved
|
IdentifyingDescriptions
|
An array of free-form strings providing explanations and
details behind the entries in the OtherIdentifyingInfo array. Note
that each entry of this array is related to the entry in OtherIdentifyingInfo
that is located at the same index.
|
RequestedState
|
An integer enumeration that indicates the last requested
or desired state for the element, irrespective of the mechanism through
which it was requested. 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.
Refer to the EnabledState property description for explanations of
the values in the RequestedState enumeration.
Unknown (0) indicates
the last requested state for the element is unknown.
-
NOTE: The value
No Change
(5)
has been deprecated instead of indicating the last requested
state is
Unknown (0). If the last requested or desired state
is unknown, RequestedState should have the value
Unknown (0), but may have the value
No Change (5).
There
are two new values in RequestedState that build on the statuses of
EnabledState. These are
Reboot (10) and
Reset (11).
Shut Down requests an orderly transition to the Disabled
state, and may 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. If knowledge of
the last RequestedState is not supported for the EnabledLogicalElement,
the property is NULL or has the value 12
Not Applicable.
Possible values are:
- 0 = Unknown
- 2 = Enabled
- 3 = Disabled
- 4 = Shut Down
- 5 = No Change
- 6 = Offline — Indicates that the element has been requested to
transition to the Enabled but Offline EnabledState.
- 7 = Test
- 8 = Deferred
- 9 = Quiesce
- 10 = Reboot — Refers to doing a
Shut Down and then moving
to an
Enabled state.
- 11 = Reset — Indicates that the element is first
Disabled and then
Enabled.
- 12 = Not Applicable
- .. = DMTF Reserved
- 32768..65535 = Vendor Reserved
|
Speed
|
USB Port Speed in bits per second. This speed is determined
and set by the attached Device. The
attached Device is indicated
using the USBConnection association. At this time, only several Port
speeds are valid. These are: 1.5Mbps and 12Mbps. The value 0 can also
be specified to indicate that the current speed is
unknown or
1 to indicate that the speed is
other than 1.5 or 12Mbps. Possible
values are: 0, 1, 1500000, 12000000
|
SystemCreationClassName
|
The CreationClassName of the scoping system.
|
SystemName
|
The System Name of the scoping system.
|
TransitioningToState
|
Indicates the target state to which the instance is transitioning.
Possible values are:
- 0 = Unknown
- 2 = Enabled
- 3 = Disabled
- 4 = Shut Down
- 5 = No Change — Indicates that no transition is in progress.
- 6 = Offline
- 7 = Test
- 8 = Defer
- 9 = Quiesce
- 10 = Reboot
- 11 = Reset
- 12 = Not Applicable — Indicates the implementation does not support
representing ongoing transitions.
A value other than
5 or
12 identifies the state
to which the element is in the process of transitioning.
