CIM_PhysicalMemory

Description

InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: <OrgID>:<LocalID> Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>. <LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above "preferred" algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. If not set to null for DMTF-defined instances, the "preferred" algorithm must be used with the <OrgID> set to CIM.

Caption

string

Description	The Caption property is a short textual description (one- line string) of the object.
MaxLen	64

Description

string

Override	Description
Description	A textual description of the PhysicalElement.
MappingStrings	MIF.DMTF\|FRU\|003.3

ElementName

string

Override	ElementName
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalName
Description	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.

InstallDate

datetime

Description	A datetime value that indicates when the object was installed. Lack of a value does not indicate that the object is not installed.
MappingStrings	MIF.DMTF\|ComponentID\|001.5

Name

string

Description	The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.
MaxLen	1024

OperationalStatus

uint16[]

Description	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. 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.

StatusDescriptions

string[]

Description	Strings describing the various OperationalStatus array values. For example, if "Stopping" is the value assigned to OperationalStatus, then this property may contain an explanation as to why an object is being stopped. Note that entries in this array are correlated with those at the same array index in OperationalStatus.

Status

string

Deprecated	CIM_ManagedSystemElement.OperationalStatus
Description	A string indicating the current status of the object. Various operational and non-operational statuses are defined. This property is deprecated in lieu of OperationalStatus, which includes the same semantics in its enumeration. This change is made for 3 reasons: 1) Status is more correctly defined as an array. This definition overcomes the limitation of describing status using a single value, when it is really a multi-valued property (for example, an element might be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. 3) The change to a uint16 data type was discussed when CIM V2.0 was defined. However, existing V1.0 implementations used the string property and did not want to modify their code. Therefore, Status was grandfathered into the Schema. Use of the deprecated qualifier allows the maintenance of the existing property, but also permits an improved definition using OperationalStatus.

HealthState

uint16

Description	Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The possible values are 0 to 30, where 5 means the element is entirely healthy and 30 means the element is completely non-functional. The following continuum is defined: "Non-recoverable Error" (30) - The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost. "Critical Failure" (25) - The element is non-functional and recovery might not be possible. "Major Failure" (20) - The element is failing. It is possible that some or all of the functionality of this component is degraded or not working. "Minor Failure" (15) - All functionality is available but some might be degraded. "Degraded/Warning" (10) - 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 might not be operating at optimal performance or it might be reporting recoverable errors. "OK" (5) - The element is fully functional and is operating within normal operational parameters and without error. "Unknown" (0) - The implementation cannot report on HealthState at this time. DMTF has reserved the unused portion of the continuum for additional HealthStates in the future.

Tag

string

Key	TRUE
Description	An arbitrary string that uniquely identifies the Physical Element and serves as the key of the Element. The Tag property can contain information such as asset tag or serial number data. The key for PhysicalElement is placed very high in the object hierarchy in order to independently identify the hardware or entity, regardless of physical placement in or on Cabinets, Adapters, and so on. For example, a hotswappable or removable component can be taken from its containing (scoping) Package and be temporarily unused. The object still continues to exist and can even be inserted into a different scoping container. Therefore, the key for Physical Element is an arbitrary string and is defined independently of any placement or location-oriented hierarchy.
MaxLen	256

CreationClassName

string

Key	TRUE
Description	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.
MaxLen	256

Manufacturer

string

Description	The name of the organization responsible for producing the PhysicalElement. This organization might be the entity from whom the Element is purchased, but this is not necessarily true. The latter information is contained in the Vendor property of CIM_Product.
MaxLen	256
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalMfgName, MIF.DMTF\|FRU\|003.4

Model

string

Description	The name by which the PhysicalElement is generally known.
MaxLen	256
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalDescr, MIF.DMTF\|FRU\|003.5

SKU

string

Description	The stock-keeping unit number for this PhysicalElement.

SerialNumber

string

Description	A manufacturer-allocated number used to identify the Physical Element.
MaxLen	256
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalSerialNum, MIF.DMTF\|FRU\|003.7

Version

string

Description	A string that indicates the version of the PhysicalElement.
MaxLen	64
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalHardwareRev, MIF.DMTF\|FRU\|003.8

PartNumber

string

Description	The part number assigned by the organization that is responsible for producing or manufacturing the PhysicalElement.
MaxLen	256
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalModelName

OtherIdentifyingInfo

string

Write	TRUE
Description	OtherIdentifyingInfo captures data in addition to Tag information. This information could be used to identify a Physical Element. One example is bar code data associated with an Element that also has an asset tag. Note that if only bar code data is available and is unique or able to be used as an Element key, this property would be null and the bar code data would be used as the class key, in the Tag property.
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalAlias

PoweredOn

boolean

Description

Boolean that indicates whether the PhysicalElement is powered on (TRUE) or is currently off (FALSE).

ManufactureDate

datetime

Description

The date that this PhysicalElement was manufactured.

VendorEquipmentType

string

Description	A vendor-specific hardware type for the PhysicalElement. It describes the specific equipment type for the element, as defined by the vendor or manufacturer.
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalVendorType

UserTracking

string

Write	TRUE
Description	User-assigned and writeable asset-tracking identifier for the PhysicalElement.
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalAssetID

CanBeFRUed

boolean

Description	Boolean that indicates whether this PhysicalElement can be FRUed (TRUE) or not (FALSE).
MappingStrings	MIB.IETF\|Entity-MIB.entPhysicalIsFRU

RemovalConditions

uint16

Description	The RemovalCapabilites property is used to describe the conditions under which a PhysicalPackage can be removed. Since all PhysicalPackages are not removable, this property defaults to 2, 'Not Applicable'.
ValueMap	0, 2, 3, 4
Values	"Unknown" [0] "Not Applicable" [2] "Removable when off" [3] "Removable when on or off" [4]

Removable

boolean

Deprecated

CIM_PhysicalComponent.RemovalConditions

Description

The use of this property is being deprecated. Instead RemovalConditions should be used. The RemovalConditions property addresses whether a PhysicalComponent is removable with or without power being applied. A PhysicalComponent is Removable if it is designed to be taken in and out of the physical container in which it is normally found, without impairing the function of the overall packaging. A Component can still be Removable if power must be 'off' in order to perform the removal. If power can be 'on' and the Component removed, then the Element is both Removable and HotSwappable. For example, an upgradeable Processor chip is Removable.

Replaceable

boolean

Deprecated

No Value

Description

The use of this property is being deprecated because it is redundant with the FRU class and its associations. A PhysicalComponent is Replaceable if it is possible to replace (FRU or upgrade) the Element with a physically different one. For example, some ComputerSystems allow the main Processor chip to be upgraded to one of a higher clock rating. In this case, the Processor is said to be Replaceable. All Removable Components are inherently Replaceable.

HotSwappable

boolean
