Name | Data Type | Qualifiers |
Name | Data Type | Value | Scope | Flavors |
Caption | string |
Description | string | The Caption property is a short textual description (one- line string) of the object. | None | TRANSLATABLE= true |
MaxLen | uint32 | 64 | None | None |
Description | string |
Description | string | The Description property provides a textual description of the object. | None | TRANSLATABLE= true |
ElementName | string |
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. | None | TRANSLATABLE= true |
Generation | uint64 |
Description | string | Generation is an optional, monotonically increasing property that may be used to identify a particular generation of the resource represented by this class.
If Generation is supported by the implementation, its value shall not be null.
Except as otherwise specified, a value (including null) of Generation specified at creation time shall be replaced by null if Generation is not supported by the implementation or shall be a, (possibly different), non-null value if the implementation does support Generation.
After creation and if supported, Generation shall be updated, at least once per access, whenever the represented resource is modified, regardless of the source of the modification.
Note: the Generation value only needs to be updated once between references, even if the resource is updated many times. The key point is to assure that it will be different if there have been updates, not to count each update.
Note: unless otherwise specified, the value of Generation within one instance is not required to be coordinated with the value of Generation in any other instance.
Note:the semantics of the instance, (as defined by its creation class), define the underlying resource. That underlying resource may be a collection or aggregation of resources. And, in that case, the semantics of the instance further define when updates to constituent resources also require updates to the Generation of the collective resource. Default behavior of composite aggregations should be to update the Generation of the composite whenever the Generation of a component is updated.
Subclasses may define additional requirements for updates on some or all of related instances.
For a particular instance, the value of Generation may wrap through zero, but the elapsed time between wraps shall be greater than 10's of years.
This class does not require Generation to be unique across instances of other classes nor across instances of the same class that have different keys. Generation shall be different across power cycles, resets, or reboots if any of those actions results in an update. Generation may be different across power cycles, resets, or reboots if those actions do not result in an update. If the Generation property of an instance is non-null, and if any attempt to update the instance includes the Generation property, then if it doesn't match the current value, the update shall fail.
The usage of this property is intended to be further specified by applicable management profiles.
Typically, a client will read the value of this property and then supply that value as input to an operation that modifies the instance in some means. This may be via an explicit parameter in an extrinsic method or via an embedded value in an extrinsic method or intrinsic operation.
For example: a profile may require that an intrinsic instance modification supply the Generation property and that it must match for the modification to succeed. | None | TRANSLATABLE= true |
Experimental | boolean | true | TOSUBCLASS= false | None |
InstanceID | string |
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'. | None | TRANSLATABLE= true |
Key | boolean | true | None | OVERRIDABLE= false

Override | string | InstanceID | TOSUBCLASS= false | None |
LoadBalanceAlgorithm | uint16 |
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. | None | TRANSLATABLE= true |
ModelCorrespondence | string | CIM_RedundancySet.OtherLoadBalanceAlgorithm | None | None |
ValueMap | string | 0, 1, 2, 3, 4, 5, 6, 7 | None | None |
Values | string | Unknown, Other, No Load Balancing, Round Robin, Least Blocks, Least IO, Address Region, Product Specific | None | TRANSLATABLE= true |
Write | boolean | true | None | None |
MaxNumberSupported | uint32 |
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. | None | TRANSLATABLE= true |
MinNumberNeeded | uint32 |
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. | None | TRANSLATABLE= true |
MinValue | sint64 | 0 | None | None |

ModelCorrespondence | string | CIM_RedundancySet.TypeOfSet | None | None |
RedundancyStatus | uint16 |
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 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. | None | TRANSLATABLE= true |

Values | string | Unknown, DMTF Reserved, Fully Redundant, Degraded Redundancy, Redundancy Lost, Overall Failure | None | TRANSLATABLE= true |
TypeOfAlgorithm | uint16 |
Description | string | TypeOfAlgorithm specifies the algorithm used for storage data redundancy and reconstruction. For example, 'P+Q' (=5) or 'P+S' (=7) may be specified. | None | TRANSLATABLE= true |

TypeOfSet | uint16 |
ArrayType | string | Indexed | None | OVERRIDABLE= false
|
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. N+1 is a special case of N+M redundancy where M=1. A value of N+1 (=2) shall be used for N+M redundancy. - 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. | None | TRANSLATABLE= true |
