You can create a WebSphere® Application Server Network Deployment cluster that uses a shared disk and a WebSphere Application Server profile across multiple nodes. The shared disk can be mounted on one active node where you can start WebSphere Application Server services and applications. To create a shared disk cluster, you use cluster management software, such as System Automation for Multiplatforms.
You can configure a service IP to automate the failover from one node to another. The cluster manager can automatically mount the file system on the active node. This solution is useful when a load-balanced cluster is not required. You can minimize the disk space that is needed to support a redundant system environment.
For more information about how to configure the cluster manager in active-passive mode, see the WebSphere Application Server V6: High Availability Solutions IBM® Redbooks® publication. The configuration documentation for cluster manager software that you use can provide further information about creating policies.
