Class CIM_StorageRedundancySet Qualifiers Name Type Value From Class Experimental boolean true CIM_StorageRedundancySet Version string 2.8.1000 CIM_StorageRedundancySet Description string A class derived from RedundancySet describing storage-related redundancy information. StorageRedundancySets are used to protect user data. They aggregate one or more underlying StorageExtents, associated via MemberOfCollection, and produce one or more higher-level Extents. The Extents are related to each other via a BasedOn association. And, the higher level Extent is related to the StorageRedundancy Set via the LogicalIdentity association. Note that StorageRedundancySets may overlap in their aggregation of members. If this occurs, the overlapping Extents SHOULD NOT contain any check data. CIM_StorageRedundancySet Description string A 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 Description string SystemSpecificCollection 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 Description string Collection is an abstract class that provides a common superclass for data elements that represent collections of ManagedElements and its subclasses. CIM_Collection 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 TypeOfSet Qualifiers Name Type Value From Class Description string TypeOfSet 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 ValueMap string [See below.] CIM_RedundancySet Values string Unknown

Property MinNumberNeeded Qualifiers Name Type Value From Class Description string MinNumberNeeded 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. CIM_RedundancySet MinValue sint64 0 CIM_RedundancySet
Property MaxNumberSupported Qualifiers Name Type Value From Class Description string MaxNumberSupported 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 Name Type Value From Class Description string VendorIdentifyingInfo captures the vendor identifying data for the RedundancySet. One example is the product name for a cluster. CIM_RedundancySet

Property LoadBalanceAlgorithm Qualifiers Name Type Value From Class Write boolean true CIM_RedundancySet Description string The 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 ValueMap string [See below.] CIM_RedundancySet Values string Unknown

Property InstanceID Qualifiers Name Type Value From Class Key boolean true CIM_SystemSpecificCollection Description string Within 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 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

Method Failover Qualifiers Name Type Value From Class Description string This 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.
