Versionstring2.10.0 CIM_RedundancySet
DescriptionstringA class derived from SystemSpecificCollection that is a special collection of ManagedElements. This collection indicates that the aggregated elements together provide redundancy, or that redundancy is provided via sparing. All elements collected in a RedundancySet SHOULD be instantiations of the same object class. CIM_RedundancySet
DescriptionstringSystemSpecificCollection represents the general concept of a collection that is scoped (or contained) by a System. It represents a Collection that has meaning only in the context of a System, a Collection whose elements are restricted by the definition of the System, or both of these types of Collections. This meaning is explicitly described by the (required) association, HostedCollection. An example of a SystemSpecificCollection is a Fibre Channel zone that collects network ports, port groupings, and aliases (as required by a customer) in the context of an AdminDomain. The Collection is not a part of the domain, but merely an arbitrary grouping of the devices and other Collections in the domain. In other words, the context of the Collection is restricted to the domain, and its members are also limited by the domain. CIM_SystemSpecificCollection
DescriptionstringCollection is an abstract class that provides a common superclass for data elements that represent collections of ManagedElements and its subclasses. CIM_Collection
DescriptionstringManagedElement is an abstract class that provides a common superclass (or top of the inheritance tree) for the non-association classes in the CIM Schema. CIM_ManagedElement

Property RedundancyStatus Qualifiers
NameTypeValueFrom Class
DescriptionstringRedundancyStatus 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 configured elements are degraded, missing or failed but that the number of elements in the set is still greater than the minimum required ( ’ MinNumberNeeded ’ ); ’ Redundancy Lost ’ (4) means that sufficient configured elements are missing or failed that no redundancy is available and the next failure experienced will cause overall failure. ’ Overall Failure ’ (5) means that there has been an overall failure of the RedundancySet.

Property TypeOfSet Qualifiers
NameTypeValueFrom Class
DescriptionstringTypeOfSet provides information on the type of redundancy. - N+1 (=2) indicates all members are active, are unaware and function independent of one another. However, there exist at least one extra member to achieve functionality. ’ Sparing ’ is implied (i.e. each member can be a spare for the other(s). An example of N+1 is a system that has 2 power supplies, but needs only 1 power supply to functioning properly. - Load Balanced (=3) indicates all members are active. However, there functionality is not independent of each other. Their functioning is determined by some sort of load balancing algrothim (implemented in hardware and/or software). ’ Sparing ’ is implied (i.e. each member can be a spare for the other(s). - Sparing (=4) indicates that all members are active and are aware of each others. However, their functionality is independent until failover. Each member can be a spare for the other(s). - Limited Sparing (=5) indicates that all members are active, and they may or may not be aware of each and they are not spares for each other. Instead, their redundancy is indicated by the IsSpare relationship. CIM_RedundancySet

Property MinNumberNeeded Qualifiers
NameTypeValueFrom Class
DescriptionstringMinNumberNeeded indicates the smallest number of elements that MUST be operational in order to function. For example, in an N+1 redundancy relationship, the MinNumberNeeded property is set equal to N. In a ’ LimitedSparing ’ environment, this property is meaningless and SHOULD be set to zero.

Property MaxNumberSupported Qualifiers
NameTypeValueFrom Class
DescriptionstringMaxNumberSupported indicates the largest number of elements that can participate in the RedundancySet. A value of 0 indicates there is no limit on the number of elements. CIM_RedundancySet

Property VendorIdentifyingInfo Qualifiers
NameTypeValueFrom Class
DescriptionstringVendorIdentifyingInfo captures the vendor identifying data for the RedundancySet. One example is the product name for a cluster. CIM_RedundancySet

Property LoadBalanceAlgorithm Qualifiers
NameTypeValueFrom Class
Writebooleantrue CIM_RedundancySet
DescriptionstringThe current load balance algorithm. Least Blocks, Least IO, and Address Region are used in storage device path redundancy drivers to optimize load balancing by routing requests to a path with the least queued blocks or IO requests, or based on locality of reference. ’ Product Specific ’ indicates that the algorithm is optimized for a particular type of product. Information about that product SHOULD be provided in an associated CIM_Product instance. CIM_RedundancySet

Property InstanceID Qualifiers
NameTypeValueFrom Class
Keybooleantrue CIM_SystemSpecificCollection
DescriptionstringWithin the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. 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 unique name. It can be a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID. Or, it could be a registered ID that is 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 re-used to identify different underlying (real-world) elements. If the above ’ preferred ’ algorithm is not used, the defining entity must ensure that the resulting InstanceID is not re-used as any of InstanceIDs produced by this or other providers for the NameSpace of this instance. For DMTF-defined instances, the ’ preferred ’ algorithm must be used with the < OrgID > set to ’ CIM ’ . CIM_SystemSpecificCollection

Property Caption Qualifiers

Property Description Qualifiers
NameTypeValueFrom Class
DescriptionstringThe Description property provides a textual description of the object. CIM_ManagedElement

Property ElementName Qualifiers
NameTypeValueFrom Class
DescriptionstringA 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

Method Qualifiers

Method Failover Qualifiers
NameTypeValueFrom Class
DescriptionstringThis method forces a failover from one ManagedElement to another. There are two parameters to the Failover method. - FailoverFrom is a reference to an ’ active ’ ManagedElement that will become inactive after the method. This element SHOULD be part of the RedundancySet via a MemberOfCollection relationship. - FailoverTo is a reference to the ManagedElement that will take over for the FailoverFrom element. This element SHOULD either be a member of the RedundancySet or be associated with the RedundancySet via an IsSpare relationship. Upon sucessful completion: - the FailoverTo element SHOULD be associated to the RedundancySet via MemberOfCollection. - the FailFrom element SHOULD either still be associated to the RedundandySet via MemberOfCollection with a OperationalStatus or EnableState that indicates it not active, or it SHOULD be associated to the ’ Spared ’ collection via the MemberOfCollection association.
