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.
|
Dedicated
|
Enumeration indicating the purpose(s) for which the ComputerSystem
is dedicated, if any, and the functionality provided. For example,
one could specify that the System is dedicated to
Print (value
= 11)
or acts as a
Hub (value = 8).
Also, a value
=
0 indicates this is a general purpose system,
Not Dedicated but that it also hosts
Print (value = 11) or mobile phone
Mobile User Device (value = 17) services.
A clarification
is needed with respect to the value
17 (Mobile User Device). An example of a dedicated user device is a mobile phone or a barcode
scanner in a store that communicates via radio frequency. These systems
are quite limited in functionality and programmability, and are not
considered
general purpose computing platforms. Alternately,
an example of a mobile system that is
general purpose (that
is, is NOT dedicated) is a hand-held computer. Although limited in
its programmability, new software can be downloaded and its functionality
expanded by the user.
The management scope
of a
Management Controller is typically a single managed system
in which it is contained.
Possible values are:
- 0 = Not Dedicated
- 1 = Unknown
- 2 = Other
- 3 = Storage
- 4 = Router
- 5 = Switch
- 6 = Layer 3 Switch
- 7 = Central Office Switch
- 8 = Hub
- 9 = Access Server
- 10 = Firewall
- 11 = Print
- 12 = I/O
- 13 = Web Caching
- 14 = Management — Indicates this instance is dedicated to hosting
system management software.
- 15 = Block Server
- 16 = File Server
- 17 = Mobile User Device
- 18 = Repeater
- 19 = Bridge/Extender
- 20 = Gateway
- 21 = Storage Virtualizer
- 22 = Media Library
- 23 = ExtenderNode
- 24 = NAS Head
- 25 = Self-contained NAS
- 26 = UPS
- 27 = IP Phone
- 28 = Management Controller — Indicates this instance represents
specialized hardware dedicated to systems management (i.e., a Baseboard
Management Controller (BMC) or service processor).
- 29 = Chassis Manager — Indicates this instance represents a system
dedicated to management of a blade chassis and its contained devices.
This value would be used to represent a Shelf Controller. A
Chassis
Manager
is an aggregation point for management and may rely on
subordinate management controllers for the management of constituent
parts.
- 30 = Host-based RAID controller — Indicates this instance represents
a RAID storage controller contained within a host computer.
- 31 = Storage Device Enclosure — Indicates this instance represents
an enclosure that contains storage devices.
- 32 = Desktop
- 33 = Laptop
- 34 = Virtual Tape Library — Is the emulation of a tape library
by a Virtual Library System.
- 35 = Virtual Library System — Uses disk storage to emulate tape
libraries.
- 36..32567 = DMTF Reserved
- 32568..65535 = Vendor Reserved
|
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 an administrator's default
or startup configuration 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. For example, shutting down (value =
4) and starting (value =
10) are transient states between enabled
and disabled.
Possible values are:
- 0 = Unknown
- 1 = Other
- 2 = Enabled — Indicates that the element is or could be executing
commands, will process any queued commands, and queues new requests.
- 3 = Disabled — Indicates that the element will not execute 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
|
HealthState
|
Indicates the current health of the element. This attribute
expresses the health of this element but not necessarily that of its
subcomponents.
DMTF has reserved the unused portion of the
continuum for additional HealthStates in the future.
Possible
values are:
- 0 = Unknown — The implementation cannot report on HealthState
at this time.
- 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 OtherIdentifying Info array. Note,
each entry of this array is related to the entry in OtherIdentifyingInfo
that is located at the same index.
|
Name
|
The inherited Name serves as the key of a system instance
in an enterprise environment.
|
OperationalStatus
|
Indicates the current statuses of the element. Various operational
statuses are defined. Many of the enumeration's values are self-explanatory.
Possible values are:
- 0 = Unknown
- 1 = Other
- 2 = OK
- 3 = Degraded
- 4 = Stressed - Indicates that the element is functioning, but
needs attention. Examples of
Stressed states are overload,
overheated, and so on.
- 5 = Predictive Failure — Indicates that an element is functioning
nominally but predicting a failure in the near future.
- 6 = Error
- 7 = Non-Recoverable Error
- 8 = Starting
- 9 = Stopping
- 10 = Stopped — Implies a clean and orderly stop.
- 11 = In Service — Describes an element being configured, maintained,
cleaned, or otherwise administered.
- 12 = No Contact — Indicates that the monitoring system has knowledge
of this element, but has never been able to establish communications
with it.
- 13 = Lost Communication — Indicates that the ManagedSystem Element
is known to exist and has been contacted successfully in the past,
but is currently unreachable.
- 14 = Aborted — Implies an abrupt stop where the state and configuration
of the element may need to be updated.
- 15 = Dormant — Indicates that the element is inactive or quiesced.
- 16 = Supporting Entity in Error — Indicates that this element
may 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.
- 17 = 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).
- 18 = Power Mode — Indicates that the element has additional power
model information contained in the Associated PowerManagementService
association.
- .. = DMTF Reserved
- 0x8000.. = Vendor Reserved
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.
|
OtherIdentifyingInfo
|
Captures additional data, beyond System Name information,
that could be used to identify a ComputerSystem. One example would
be to hold the Fibre Channel World-Wide Name (WWN) of a node.
-
NOTE: If only the
Fibre Channel name is available and is unique (able to be used as
the System key), then this property would be NULL and the WWN would
become the System key, its data placed in the Name property.
|
PrimaryStatus
|
Provides a high level status value, intended to align with
Red-Yellow-Green type representation of status. It should be used
in conjunction with DetailedStatus to provide high level and detailed
health status of the ManagedElement and its subcomponents.
Possible values are:
- 0 = Unknown — Indicates the implementation is in general capable
of returning this property, but is unable to do so at this time.
- 1 = OK — Indicates the ManagedElement is functioning normally.
- 2 = Degraded — Indicates the ManagedElement is functioning below
normal.
- 3 = Error — Indicates the ManagedElement is in an Error condition.
- .. = DMTF Reserved
- 0x8000.. = Vendor Reserved
|
RequestedState
|
An integer enumeration that indicates the last requested
or desired state for the element, irrespective of the mechanism through
which it was requested.
Possible values are:
- 0 = Unknown — Indicates the last requested state for the element
is unknown.
- 2 = Enabled
- 3 = Disabled
- 4 = Shut Down
- 5 = No Change
- 6 = Offline
- 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
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.
-
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).
Offline (6) indicates that the element has been requested to transition to the
Enabled but Offline EnabledState.
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.
|
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.
|
RequestStateChange (Method)
|
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.
A return code of 0 shall indicate the state change was successfully
initiated.
A return code of 3 shall indicate that the state
transition cannot complete within the interval specified by the TimeoutPeriod
parameter.
A return code of 4096 (0x1000) shall indicate the
state change was successfully initiated, a ConcreteJob has been created,
and its reference returned in the output parameter Job. Any other
return code indicates an error condition.
