Property Description
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.
• 5 = Overall Failure - Indicates that there has been
an overall failure of the RedundancySet.
TypeOfSet
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
