Cluster and application configuration options

Configuring topology and resources

You can configure the cluster, nodes, networks, network interfaces, and the cluster repository disk and IP address using the SMIT menus under Cluster Nodes and Networks.

Once the cluster is created, manage the cluster, nodes, networks, and network interfaces using the Manage menus under Cluster Nodes and Networks in SMIT.

You can add resources and resource groups to support clustered applications under the SMIT menu Cluster Applications and Resources.

There are some options for configuring cluster topology and resource that are not required, but might be desired in some configurations. For example, by default all network interfaces discovered on cluster nodes at the time of cluster creation are included in the cluster topology configuration and are used for cluster communications, monitoring, and to keep application IP addresses highly available. It is possible to exclude some interfaces from the cluster configuration when desired.

Configuring dynamic LPAR and Capacity Upgrade on Demand resources

Using Dynamic LPAR (DLPAR) and Capacity on Demand (CoD) in a PowerHA® SystemMirror® cluster describes how to plan, integrate, configure, and troubleshoot application provisioning for PowerHA SystemMirror through the use of DLPAR CoD functions available on some IBM® Power Systems™ servers. It also includes examples and recommendations about customizing your existing pre- and post-event scripts.
