CIM_ParticipatingCS class

A Cluster is composed of two or more ComputerSystems, operating together. A ComputerSystem may participate in multiple Clusters.

When first establishing or bringing up a Cluster, only one ComputerSystem may be defined as participating in it. Therfore, the cardinality of the association for the ComputerSystem reference is Min(1).

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Syntax

[Abstract, Association, UUID("{8A5CD126-FD8B-4eb2-AEDF-5DC22B6DE989}"), AMENDMENT]

Members

The CIM_ParticipatingCS class has these types of members:

Properties

The CIM_ParticipatingCS class has these properties.

Antecedent

Data type: CIM_ComputerSystem

Access type: Read-only

Qualifiers: Override ("Antecedent"), Min (1)

The ComputerSystem which participates in the Cluster.

Dependent

Data type: CIM_Cluster

Access type: Read-only

Qualifiers: Override ("Dependent")

The Cluster.

RoleOfNode

Data type: uint16

Access type: Read-only

RoleOfNode indicates whether the Cluster nodes are peers (value = 2), connected in a master-slave/primary-secondary relationship (values = 3 for primary, 4 for secondary), available in a standby configuration (5) or of some other (1) or unknown (0) relationship. In a System/390 environment, the nodes are identified as "Base Plex" (value=6) or "Enhanced Plex" (value=7).

Unknown (0)

Other (1)

Peer (2)

Primary (3)

Secondary (4)

Standby (5)

Base Plex (6)

Enhanced Plex (7)

StateOfNode

Data type: uint16

Access type: Read-only

StateOfNode indicates the condition of the participating ComputerSystem in the Cluster. For example, one value is "Joining" (2).

Unknown (0)

Other (1)

Joining (2)

Paused (3)

Available (4)

Unavailable (5)

Degraded (6)
