Subclasses of CIM_PhysicalElement define any component of a System that has a distinct physical identity. Instances of this class can be defined as an object that can be seen or touched. All Processes, Files, and LogicalDevices are considered not to be Physical Elements. For example, it is not possible to touch the functionality of a 'modem.' You can touch only the card or package that implements the modem. The same card could also implement a LAN adapter. PhysicalElements are tangible ManagedSystemElements that have a physical manifestation of some sort. Note that the properties of PhysicalElement describe a hardware entity. Possible replacement (FRU) information is defined by following the ElementFRU association to one or more instances of the ReplacementFRU class. This definition allows a client to determine what hardware can be replaced (FRUed) and what 'spare' parts might be required by a customer or engineer doing the replacement. If it can be instrumented or manually determined that an element actually replaced (FRUed) another, then this can be described in the model using the ElementHasBeenFRUed association. | Qualifiers:Abstract Version ( "2.10.0" ) | Parameters (local in grey) | | Override ( "Description" ) MappingStrings { "MIF.DMTF|FRU|003.3" } string Description ; A textual description of the PhysicalElement. | Write MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalAssetID" } string UserTracking ; User-assigned and writeable asset-tracking identifier for the PhysicalElement. | MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalVendorType" } string VendorEquipmentType ; A vendor-specific hardware type for the PhysicalElement. It describes the specific equipment type for the element, as defined by the vendor or manufacturer. | Write MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalAlias" } string OtherIdentifyingInfo ; 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. | boolean PoweredOn ; Boolean that indicates whether the PhysicalElement is powered on (TRUE) or is currently off (FALSE). | MaxLen ( 256 ) MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalMfgName" , "MIF.DMTF|FRU|003.4" } string Manufacturer ; 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 ( 64 ) string SKU ; The stock-keeping unit number for this PhysicalElement. | MaxLen ( 256 ) Key string Tag ; 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 ) MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalDescr" , "MIF.DMTF|FRU|003.5" } string Model ; The name by which the PhysicalElement is generally known. | MaxLen ( 256 ) Key string CreationClassName ; 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. | MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalIsFRU" } boolean CanBeFRUed ; Boolean that indicates whether this PhysicalElement can be FRUed (TRUE) or not (FALSE). | datetime ManufactureDate ; The date that this PhysicalElement was manufactured. | MaxLen ( 256 ) MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalSerialNum" , "MIF.DMTF|FRU|003.7" } string SerialNumber ; A manufacturer-allocated number used to identify the Physical Element. | MaxLen ( 256 ) MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalModelName" } string PartNumber ; The part number assigned by the organization that is responsible for producing or manufacturing the PhysicalElement. | Override ( "ElementName" ) MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalName" } string ElementName ;
| MaxLen ( 64 ) MappingStrings { "MIB.IETF|Entity-MIB.entPhysicalHardwareRev" , "MIF.DMTF|FRU|003.8" } string Version ; A string that indicates the version of the PhysicalElement. | ModelCorrespondence { "CIM_ManagedSystemElement.OperationalStatus" } ArrayType ( "Indexed" ) string StatusDescriptions [ ] ; 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. | Values { "Unknown" , "Other" , "OK" , "Degraded" , "Stressed" , "Predictive Failure" , "Error" , "Non-Recoverable Error" , "Starting" , "Stopping" , "Stopped" , "In Service" , "No Contact" , "Lost Communication" , "Aborted" , "Dormant" , "Supporting Entity in Error" , "Completed" , "Power Mode" , "DMTF Reserved" , "Vendor Reserved" } ModelCorrespondence { "CIM_ManagedSystemElement.StatusDescriptions" } ValueMap { "0" , "1" , "2" , "3" , "4" , "5" , "6" , "7" , "8" , "9" , "10" , "11" , "12" , "13" , "14" , "15" , "16" , "17" , "18" , ".." , "0x8000.." } ArrayType ( "Indexed" ) uint16 OperationalStatus [ ] ; Indicates the current status(es) of the element. Various health and operational statuses are defined. Many of the enumeration's values are self- explanatory. However, a few are not and are described in more detail. 'Stressed' indicates that the element is functioning, but needs attention. Examples of 'Stressed' states are overload, overheated, etc. '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 element's state and configuration may need to be updated. 'Dormant' indicates that the element is inactive or quiesced. 'Supporting Entity in Error' describes 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. 'Completed' indicates the element has completed its operation. This value should be combined with either OK, Error, or Degraded so that a client can till if the complete operation passed (Completed with OK), and failure (Completed with Error). Completed with Degraded would imply the operation finished, but did not complete OK or report an error. 'Power Mode' indicates 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 since it required the DEPRECATED qualifier. Due to the widespread use of the existing Status property in management applications, it is strongly RECOMMENDED that providers/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 (since it is single-valued) SHOULD also provide the primary status of the element. | MaxLen ( 1024 ) string Name ; 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. | MappingStrings { "MIF.DMTF|ComponentID|001.5" } datetime InstallDate ; A datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed. | MaxLen ( 10 ) Deprecated { "CIM_ManagedSystemElement.OperationalStatus" } ValueMap { "OK" , "Error" , "Degraded" , "Unknown" , "Pred Fail" , "Starting" , "Stopping" , "Service" , "Stressed" , "NonRecover" , "No Contact" , "Lost Comm" , "Stopped" } string Status ; 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 overcomes the limitation of describing status via a single value, when it is really a multi-valued property (for example, an element may be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. And, 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. | MaxLen ( 64 ) string Caption ; The Caption property is a short textual description (one- line string) of the object. |
