Steps for configuring a cluster

Here are the steps to configure the typical cluster components.


What You Do	Description
Step 1: Configure a basic cluster, or a cluster with an application	Use the SMIT menus under Initial Cluster Setup (Typical) to configure a basic cluster with default options and discovered network components. You can use one of the Smart Assists to configure a cluster with an application.
Step 2: Configure additional topology components	You can choose to configure the cluster with the SMIT menus under Initial Cluster Setup (Custom) if you want to create it piece by piece. This may be because you want to name the networks or nodes with something other than the default names, or because you want to choose specific network interfaces to support clustered applications (by default all interfaces will be used). Regardless of how you initially setup the cluster, you can add or remove components to the initial configuration using the Manage menus under the Cluster Nodes and Networks SMIT menu.
Step 3: Configure the cluster resources	Configure the resources to be made highly available. Use the menus under the SMIT path Cluster Applications and Resources > Resources to configure resources that are to be shared among the nodes in the cluster. You can configure these resources: Application IP addresses and IP labels Application controllers (start and stop scripts for the applications) Volume groups Logical volumes and file systems Raw disks (for concurrently accessed data) Tape resources NFS exports and cross-mounts Custom user-defined resources
Step 4: Configure the resource groups	Use the menus under the SMIT path Cluster Applications and Resources > Resources Groups to create the resource groups you have planned for each set of related resources.
Step 5: Put the resources to be managed together into their respective resource groups	To assign resources to each resource group use the following SMIT menu, Cluster Applications and Resources > Resource Groups - Change/Show Resources and Attributes for a Resource Group.
Step 6: Adjust log viewing and management	(Optional) Adjust log viewing and management using the SMIT dialogs under Problem Determination Tools > PowerHA SystemMirror Logs.
Step 7: Verify and synchronize the cluster configuration	Use the Verify and Synchronize Cluster Configuration dialog to verify that the desired configuration is valid and to ensure that all nodes in the cluster have the same view of the configuration.
Step 8: Display the cluster configuration	(Optional) Use the PowerHA SystemMirror Configuration dialog, found under SMIT menu Cluster Nodes and Networks > Manage the Cluster to view the cluster topology and resources configuration.
Step 9: Make further additions or adjustments to the cluster configuration	(Optional) You may want to perform some optional cluster configuration for your application environment needs. Such additions or adjustments include, for example: Configuring a distribution preference for service IP aliases Configuring resource group runtime policies, including Workload Manager Adding resource group timers for startup and fallback Configuring dependencies between resource groups Adding application monitors Configuring File Collections Configuring cluster users or security Customizing remote notifications (pager, SMS messages, and e-mail) Customizing cluster events
Step 10: Test the cluster before it goes into the production environment	(Recommended) Use the Cluster Test Tool, found under SMIT menu Problem Determination Tools, to test recovery procedures for the cluster. Note: The Cluster Test Tool is not fully supported by the latest PowerHA releases.
