Access
|
Access describes whether the media is readable (value =
1), writeable (value =
2), or both (value =
3).
Unknown (0) and
Write Once (4) can also be defined.
Possible values are:
- 0 = Unknown
- 1 = Readable
- 2 = Writeable
- 3 = Read/Write Supported
- 4 = Write Once
|
BlockSize
|
Size in bytes of the blocks which form this StorageExtent.
If variable block size, then the maximum block size in bytes should
be specified. If the block size is unknown or if a block concept is
not valid (for example, for AggregateExtents, Memory or LogicalDisks),
enter a 1.
|
ConsumableBlocks
|
The maximum number of blocks, of size BlockSize, which are
available for consumption when layering StorageExtents using the BasedOn
association. This property only has meaning when this StorageExtent
is an Antecedent reference in a BasedOn relationship. For example,
a StorageExtent could be composed of 120 blocks. However, the Extent
itself may use 20 blocks for redundancy data. If another StorageExtent
is BasedOn this Extent, only 100 blocks would be available to it.
This information
(100 blocks is available for consumption) is
indicated in the ConsumableBlocks property.
|
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 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
|
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
|
ErrorMethodology
|
ErrorMethodology for Memory is a string property that indicates
whether parity or CRC algorithms, ECC or other mechanisms are used.
Details on the algorithm can also be supplied.
|
FailOverState
|
An integer enumeration indicating that active memory has
failed and the spare or backup memory may have taken over.
Possible values are:
- 0 = Unknown
- 1 = Other
- 2 = None
- 3 = Active
|
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
|
NumberOfBlocks
|
Total number of logically contiguous blocks, of size Block
Size, which form this Extent. The total size of the Extent can be
calculated by multiplying BlockSize by NumberOfBlocks. If the BlockSize
is
1, this property is the total size of the Extent.
|
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
- 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
- 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 data, in addition to DeviceID information, that
could be used to identify a LogicalDevice. For example, you could
use this property to hold the operating system's user-friendly name
for the Device.
|
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
|
Primordial
|
If true,
Primordial indicates that the containing
System does not have the ability to create or delete this operational
element. This is important because StorageExtents are assembled into
higher-level abstractions using the BasedOn association. Although
the higher-level abstractions can be created and deleted, the most
basic, (that is, primordial), hardware-based storage entities cannot.
They are physically realized as part of the System, or are actually
managed by some other System and imported as if they were physically
realized. In other words, a Primordial StorageExtent exists in, but
is not created by its System and conversely a non-Primordial StorageExtent
is created in the context of its System. For StorageVolumes, this
property will generally be false. One use of this property is to enable
algorithms that aggregate StorageExtent. ConsumableSpace across all,
StorageExtents but that also want to distinquish the space that underlies
Primordial StoragePools. Since implementations are not required to
surface all Component StorageExtents of a StoragePool, this information
is not accessible in any other way. Purpose A free form string describing
the media and/or its use. RedundancyConfiguration is an integer enumeration
indicating the redundancy configuration when active memory fails.
Possible values are:
- 0 = Unknown
- 1 = Other
- 2 = Disabled
- 3 = Spared
- 4 = Mirrored
- 5 = LockStep
|
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: 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).
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 — Indicates the last requested state for the element
is 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
|
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.
|
Volatile
|
Volatile is a property that indicates whether this memory
is volatile or not.
