ElementName
public string ElementName
- General Information:
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 that
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. Note that if there is an associated instance of
CIM_EnabledLogicalElementCapabilities, restrictions on this properties may
exist as defined in ElementNameMask and MaxElementNameLen properties defined
in that class.

OperationalStatus
public uint16[2] OperationalStatus
- General Information:
Indicates the current statuses of the
element. Various operational statuses are defined. Many of the enumeration's
values are self-explanatory. However, a few are not and are described here in
more detail.
"Stressed" indicates that the element is functioning, but
needs attention. Examples of "Stressed" states are overload, overheated, and
so on.
"Predictive Failure" indicates that an element is functioning
nominally but predicting a failure in the near future.
"In Service"
describes an element being configured, maintained, cleaned, or otherwise
administered.
"No Contact" indicates that the monitoring system has
knowledge of this element, but has never been able to establish communications
with it.
"Lost Communication" indicates that the ManagedSystem Element is
known to exist and has been contacted successfully in the past, but is
currently unreachable.
"Stopped" and "Aborted" are similar, although the
former implies a clean and orderly stop, while the latter implies an abrupt
stop where the state and configuration of the element might need to be
updated.
"Dormant" indicates that the element is inactive or quiesced.
"Supporting Entity in Error" indicates that this element might be "OK" but
that another element, on which it is dependent, is in error. An example is a
network service or endpoint that cannot function due to lower-layer networking
problems.
"Completed" indicates that the element has completed its
operation. This value should be combined with either OK, Error, 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" indicates that the element has additional power model information
contained in the Associated PowerManagementService association.
"Relocating" indicates the element is being
relocated.
OperationalStatus replaces the Status property on
ManagedSystemElement to provide a consistent approach to enumerations, to
address implementation needs for an array property, and to provide a migration
path from today's environment to the future. This change was not made earlier
because it required the deprecated qualifier. Due to the widespread use of the
existing Status property in management applications, it is strongly
recommended that providers or instrumentation provide both the Status and
OperationalStatus properties. Further, the first value of OperationalStatus
should contain the primary status for the element. When instrumented, Status
(because it is single-valued) should also provide the primary status of the
element.

EnabledState
public uint16 EnabledState
- General Information:
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.

RequestedState
public uint16 RequestedState
- General Information:
RequestedState is 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 that the value "No
Change" (5) has been deprecated in lieu 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).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.
If knowledge of the last RequestedState is not supported for the
EnabledLogicalElement, the property shall be NULL or have the value 12 "Not
Applicable".

Capabilities
public uint16[3] Capabilities
- General Information:
Capabilities of the MediaAccessDevice. For
example, the Device may support "Random Access", removeable media and
"Automatic Cleaning". In this case, the values 3, 7 and 9 would be written to
the array.
Several of the enumerated values require some explanation: 1)
Value 11, Supports Dual Sided Media, distinguishes a Device that can access
both sides of dual sided Media, from a Device that reads only a single side
and requires the Media to be flipped; and, 2) Value 12, Predismount Eject Not
Required, indicates that Media does not have to be explicitly ejected from the
Device before being accessed by a
PickerElement.
