                CIM_System

Known Subclasses:
  CIM_ComputerSystem ME_System

    Abstract class CIM_System

extends CIM_EnabledLogicalElement

General Information:
CIM_System represents an entity made up of component parts (defined by the SystemComponent relationship), that operates as a 'functional whole'. Systems are top-level objects in the CIM hierarchy, requiring no scoping or weak relationships in order to exist and have context. It should be reasonable to uniquely name and manage a System at an enterprise level. For example, a ComputerSystem is a kind of System that can be uniquely named and independently managed in an enterprise. However, these qualities are not true for the power supply (or the power supply sub-'system') within the computer.
Although a System can be viewed as a Collection, this view is not the correct model. A Collection is simply a 'bag' that 'holds' its members. A System is a higher-level abstraction, built out of its individual components. It is more than the sum of its parts. Note that System is a subclass of EnabledLogicalElement which allows the entire abstraction to be functionally enabled or disabled at a higher level than enabling or disabling its component parts.

Field Detail

### TimeOfLastStateChange

    public datetime TimeOfLastStateChange

  General Information:
  The date or time when the EnabledState of the element last changed. If the state of the element has not changed and this property is populated, then it must be set to a 0 interval value. If a state change was requested, but rejected or not yet processed, the property must not be updated.

### EnabledDefault

    public uint16 EnabledDefault

  General Information:
  An enumerated value indicating an administrator's default or startup configuration for the Enabled State of an element. By default, the element is "Enabled" (value=2).
  Qualifiers:
  -------------

  ValueMap={2, 3, 5, 6, 7, 9, .., 32768..65535}
  Values={Enabled, Disabled, Not Applicable, Enabled but Offline, No Default, Quiesce, DMTF Reserved, Vendor Reserved}

### 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".

### OtherEnabledState

    public string OtherEnabledState

  General Information:
  A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ("Other"). This property must be set to null when EnabledState is any value other than 1.
  Qualifiers:
  -------------
  ModelCorrespondence={CIM_EnabledLogicalElement.EnabledState}

### 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.

  ModelCorrespondence={CIM_EnabledLogicalElement.OtherEnabledState}

### HealthState

    public uint16 HealthState

  General Information:
  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.
  Qualifiers:

  ValueMap={0, 5, 10, 15, 20, 25, 30, ..}
  Values={Unknown, OK, Degraded/Warning, Minor failure, Major failure, Critical failure, Non-recoverable error, DMTF Reserved}

### Status

    public string Status

  General Information:
  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.
  Qualifiers:
  -------------
  Deprecated={CIM_ManagedSystemElement.OperationalStatus}
  ValueMap={OK, Error, Degraded, Unknown, Pred Fail, Starting, Stopping, Service, Stressed, NonRecover, No Contact, Lost Comm, Stopped}
  MaxLen=10

### StatusDescriptions

    public string[] StatusDescriptions

  General Information:
  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.
  Qualifiers:
  -------------
  ArrayType=Indexed
  ModelCorrespondence={CIM_ManagedSystemElement.OperationalStatus}
  MaxLen=256

### OperationalStatus

    public uint16[] 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.
  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.

### InstallDate

    public datetime InstallDate

  General Information:
  A datetime value that indicates when the object was installed. Lack of a value does not indicate that the object is not installed.
  Qualifiers:
  -------------
  MappingStrings={MIF.DMTF|ComponentID|001.5}

### InstanceID

    public string InstanceID

  General Information:
  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.

### 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.
  Qualifiers:
  -------------
  MaxLen=256

### CreationClassName

    public string CreationClassName

  General Information:
  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.
  Qualifiers:
  -------------
  Key

### NameFormat

    public string NameFormat

  General Information:
  The System object and its derivatives are top-level objects of CIM. They provide the scope for numerous components. Having unique System keys is required. A heuristic can be defined in individual System subclasses to attempt to always generate the same System Name Key. The NameFormat property identifies how the System name was generated, using the heuristic of the subclass.
  Qualifiers:

  MappingStrings={MIF.DMTF|General Information|001.4}

### Roles

    public string[] Roles

  General Information:
  An array (bag) of strings that specifies the administrator -defined roles this System plays in the managed environment. Examples might be 'Building 8 print server' or 'Boise user directories'. A single system may perform multiple roles.
  Note that the instrumentation view of the 'roles' of a System is defined by instantiating a specific subclass of System, or by properties in a subclass, or both. For example, the purpose of a ComputerSystem is defined using the Dedicated and OtherDedicatedDescription properties.

  -------------
  Write
  MaxLen=256

### OtherIdentifyingInfo

    public string[] OtherIdentifyingInfo

  General Information:
  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 that 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.

  General Information:
  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.
