Class CIM_StorageRedundancyGroup Qualifiers Name Type Value From Class Experimental boolean true CIM_StorageRedundancyGroup Deprecated string CIM_StorageRedundancySet CIM_StorageRedundancyGroup Version string 2.8.1000 CIM_StorageRedundancyGroup Description string A class derived from RedundancyGroup containing mass storage-related redundancy information. StorageRedundancy Groups are used to protect user data. They act on one or more underlying StorageExtents, associated via ExtentRedundancyComponent and produce one or more protected StorageExtents that are associated to the underlying StorageExtents via ProtectedExtentBasedOn or CompositeExtentBasedOn. StorageRedundancyGroups may overlap. However, the underlying StorageExtents within the overlap should not contain any check data. The use of this class is being deprecated in lieu of using the StorageRedundancySet class. CIM_StorageRedundancyGroup Description string A class derived from LogicalElement that is a special collection of ManagedSystemElements. This collection indicates that the aggregated components together provide redundancy. All elements aggregated in a RedundancyGroup should be instantiations of the same object class. The use of this class is being deprecated in lieu of using the RedundancySet class. CIM_RedundancyGroup Description string CIM_LogicalElement is a base class for all the components of a System that represent abstract system components, such as Files, Processes, or LogicalDevices. CIM_LogicalElement Description string CIM_ManagedSystemElement is the base class for the System Element hierarchy. Any distinguishable component of a System is a candidate for inclusion in this class. Examples of system components include: - software components such as application servers, databases, and applications - operating system components such as files, processes, and threads - device components such as disk drives, controllers, processors, and printers - physical components such as chips and cards. CIM_ManagedSystemElement Description string ManagedElement is an abstract class that provides a common superclass (or top of the inheritance tree) for the non-association classes in the CIM Schema.

Property Qualifiers
Property TypeOfAlgorithm Qualifiers Name Type Value From Class Description string The TypeOfAlgorithm specifies the algorithm used for data redundancy and reconstruction. For example, " P+Q " (value =5) or " P+S " (7) may be specified. The value of 0, is defined as " None " to indicate that data redundancy is not active. An inactive redundancy should only be instantiated if data striping or concatenation are active. These are indicated by the IsStriped or IsConcatentated boolean properties of this RedundancyGroup.

Property IsStriped Qualifiers Name Type Value From Class Description string True indicates that the data is striped across the various StorageExtents in the Group. CIM_StorageRedundancyGroup
Property IsConcatenated Qualifiers Name Type Value From Class Description string True indicates that the data is concatenated across the various StorageExtents in the Group. CIM_StorageRedundancyGroup
Property CreationClassName Qualifiers Name Type Value From Class Key boolean true CIM_RedundancyGroup Description string 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. CIM_RedundancyGroup MaxLen uint32 256 CIM_RedundancyGroup
Property Name Qualifiers Name Type Value From Class Key boolean true CIM_RedundancyGroup Override string Name CIM_RedundancyGroup Description string The RedundancyGroup Name serves as the key for the Group ’ s instance in an enterprise environment. CIM_RedundancyGroup MaxLen uint32 256 CIM_RedundancyGroup
Property RedundancyStatus Qualifiers Name Type Value From Class Description string RedundancyStatus provides information on the state of the RedundancyGroup. " Fully Redundant " (value=2) means that all of the configured redundancy is still available; " Degraded Redundancy " (3) means that some failures have been experienced but some reduced amount of redundancy is still available; " Redundancy Lost " (4) means that a sufficient number of failures have been experienced such that no redundancy is available and the next failure experienced will cause overall failure. Also, the values, " Other " (1) and " Unknown " (0), are defined. CIM_RedundancyGroup ValueMap string [See below.] CIM_RedundancyGroup Values string Unknown

Property InstallDate Qualifiers Name Type Value From Class Description string A datetime value that indicates when the object was installed. Lack of a value does not indicate that the object is not installed. CIM_ManagedSystemElement MappingStrings string MIF.DMTF|ComponentID|001.5 CIM_ManagedSystemElement
Property Name Qualifiers Name Type Value From Class Description string 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. CIM_ManagedSystemElement MaxLen uint32 1024 CIM_ManagedSystemElement
Property OperationalStatus Qualifiers Name Type Value From Class Description string 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.

Property StatusDescriptions Qualifiers Name Type Value From Class Description string 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. CIM_ManagedSystemElement ArrayType string Indexed CIM_ManagedSystemElement ModelCorrespondence string CIM_ManagedSystemElement.OperationalStatus CIM_ManagedSystemElement
Property Status Qualifiers Name Type Value From Class Description string 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.

Property HealthState Qualifiers Name Type Value From Class Description string 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. CIM_ManagedSystemElement ValueMap string [See below.] CIM_ManagedSystemElement Values string Unknown

Property Caption Qualifiers Name Type Value From Class Description string The Caption property is a short textual description (one- line string) of the object. CIM_ManagedElement MaxLen uint32 64 CIM_ManagedElement
Property Description Qualifiers Name Type Value From Class Description string The Description property provides a textual description of the object. CIM_ManagedElement
Property ElementName Qualifiers Name Type Value From Class Description string 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. CIM_ManagedElement
