186 IBM Certification Study Guide AIX HACMP

ordinary HACMP cluster, as it is described in Chapter 7 of the

HACMP for

AIX, Version 4.3: Installation Guide

, SC23-4278.

Now the cluster environment has to be configured. Define a cluster ID and

name for your HACWS cluster and define the two nodes to HACMP.

Adapters have to be added to your cluster definition as described before. You

will have to add a boot adapter and a service adapter for both primary and

backup cws. Now that the cluster topology is defined to HACMP, you can

configure Network Modules as in the

HACMP for AIX Installation Guide

SC23-4278, and synchronize the definitions across the two cluster nodes.

With the ssp.hacws filesets comes a predefined start- and stop-script, which

has to be defined to HACMP as part of the application server definition, which

in turn has to be included in a resource group.

Recommended settings for this resource group are:

Resource Group Name [hacws_group1]

Node Relationship [rotating]

Participating Node Names [“nodename of primary cws” “nodename of

backup cws”]

Service IP label at least the hostname of the primary cws

File System the name of the file system, most probably

/spdata

Volume Groups the name of the shared volume group containing

/spdata

Application Servers the name you gave the application server before

9.1.6 Setup and Test HACWS

Both the primary and backup cws have to be addressable by their hostname,

in order to finish the configuration and check that everything is in order. So,

check if the primary cws can address the backup cws by its hostname and

vice versa. If not, use the

ifconfig command to temporarily set the interface

to the hostname on each cws. Do

NOT

use smit chinet for this, since this

would be a permanent change.

Run the command:

/usr/sbin/hacws/install_hacws -p primary_hostname -b backup_hostname -s

on the primary cws to set up HACWS with the 2 node names.
