Property Description
not reused across any 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.
DCIM_RedundancySet
Table 87. RedundancySet
Property Description
ElementName
ElementName 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: 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.
InstanceID
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 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 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. For DMTF-defined instances, the
preferred algorithm must be used with the <OrgID>set to CIM.
MinNumberNeeded
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.
RedundancyStatus
RedundancyStatus provides information on the state of the RedundancyGroup.
Possible values are:
● 0 = Unknown
● 1 = DMTF Reserved
● 2 = Fully Redundant — Indicates that all of the configured redundancy is still
available
● 3 = Degraded Redundancy — Indicates 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);
● 4 = Redundancy Lost — Indicates that sufficient configured elements are
missing or failed that no redundancy is available and the next failure experienced
will cause overall failure.
