Subelements

Quorum

Type:

QuorumType

A QuorumType element specifies the quorum device for the cluster domain.

Occurrence rules:

You can include zero or one Quorum element in your ClusterDomainType element.

PhysicalNetwork

Type:

PhysicalNetworkType

A PhysicalNetworkType element contains network interface cards that can fail over for each other. This kind of network is also called a network equivalency.

Occurrence rules:

You can include zero or more PhysicalNetwork elements in your ClusterDomainType element.

ClusterNode

Type:

ClusterNodeType

A ClusterNodeType element contains information about a particular computer or machine (also called a cluster domain node) in the cluster.

Occurrence rules:

You must specify at least one ClusterNode element in your ClusterDomainType element.

Usage notes

IBM® Tivoli® System Automation for Multiplatforms (SA MP) supports a maximum of 32 cluster domain nodes. If your cluster manager is SA MP, then you can include a maximum of 32 ClusterNode elements in your ClusterDomainType element.

Attributes

domainName (required)

You must specify a unique name for your ClusterDomainType element.

If you are using Reliable Scalable Cluster Technology (RSCT) to manage your cluster, the following restrictions apply to domainName:

• domainName can only contain the characters A to Z, a to z, digits 0 to 9, period (.), and underscore (_)
• domainName cannot be "IW"
