CIM_RedundancySet class

  • Artículo

A collection of managed elements that provides redundancy.

Note

All of the elements in the collection should be of the same class type.

The following syntax is simplified from MOF code and includes all inherited properties.

Members

The CIM_RedundancySet class has these types of members:

Methods

The CIM_RedundancySet class has these methods.

Method Description
Failover Forces a failover from one managed element to another.

Properties

The CIM_RedundancySet class has these properties.

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

A short textual description of the object.

This property is inherited from CIM_ManagedElement.

Description

Data type: string

Access type: Read-only

A textual description of the object.

This property is inherited from CIM_ManagedElement.

ElementName

Data type: string

Access type: Read-only

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.

This property is inherited from CIM_ManagedElement.

InstanceID

Data type: string

Access type: Read-only

Qualifiers: Key

Uniquely identifies an instance of this class within the scope of the containing namespace.

In order to ensure uniqueness within the namespace, the value of the InstanceID property should be constructed in the following format: OrgID:LocalID

  • OrgID must include a copyrighted, trademarked or a unique name that is owned by the business entity that defines the InstanceID, or be a registered ID that is assigned by a recognized global authority. This pattern is similar to the structure of schema class names.
  • The first colon in InstanceID must be between the OrgID andLocalID. Therefore the OrgID must not contain a colon (':').
  • LocalID is chosen by the business entity and should not be re-used to identify different underlying real-world elements.
  • If this format is not used, the defining entity must assure that the resultant InstanceID value is not re-used across any InstanceID properties that are produced by this provider or other providers for this namespace.
  • For Distributed Management Task Force (DMTF) defined instances, the pattern must be used with the OrgID set to CIM.

This property is inherited from CIM_SystemSpecificCollection.

LoadBalanceAlgorithm

Data type: uint16

Access type: Read/write

Qualifiers: ModelCorrespondence ("CIM_RedundancySet.OtherLoadBalanceAlgorithm")

The current load balancing algorithm of the redundancy set.

The possible values are:

Unknown (0)

Other (1)

No Load Balancing (2)

Round Robin (3)

Least Blocks (4)

Least IO (5)

Address Region (6)

Product Specific (7)

MaxNumberSupported

Data type: uint32

Access type: Read-only

The largest number of elements that can participate in the r edundancy set. A value of "0" indicates there is no limit on the number of elements.

MinNumberNeeded

Data type: uint32

Access type: Read-only

Qualifiers: MinValue (0)

The minimum number of elements that must be operational for redundancy to function.

This property is not used if TypeOfSet is set to "5" (limited sparing).

OtherLoadBalanceAlgorithm

Data type: string

Access type: Read/write

Qualifiers: ModelCorrespondence ("CIM_RedundancySet.LoadBalanceAlgorithm")

An array that contains descriptions of LoadBalanceAlgorithm values that are set to "1" (other).

OtherTypeOfSet

Data type: string array

Access type: Read-only

Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_RedundancySet.TypeOfSet")

An array that contains descriptions of TypeOfSet values that are set to "1" (other).

RedundancyStatus

Data type: uint16

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_RedundancySet.MinNumberNeeded")

The state of the redundancy group.

The possible values are:

Unknown (0)

DMTF Reserved (1)

Fully Redundant (2)

Degraded Redundancy (3)

Redundancy Lost (4)

Overall Failure (5)

TypeOfSet

Data type: uint16 array

Access type: Read-only

Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_RedundancySet.OtherTypeOfSet")

An array that contains information about the type of redundancy used by the collection.

The possible values are:

Unknown (0)

Other (1)

N+1 (2)

Load Balanced (3)

Sparing (4)

Limited Sparing (5)

DMTF Reserved

6 32767

Vendor Reserved

32768 65535

VendorIdentifyingInfo

Data type: string

Access type: Read-only

The vendor identifying data for the redundancy set. One example is the product name for a cluster.
