11.2 Planning and preparation

HACMP planning and configuration itself is not related to the WebSphere configuration. Refer to the HACMP planning and installation guides for the different HACMP versions to find information about how to set up your HACMP cluster. These guides are available at: 

http://www.ibm.com/servers/eServer/pseries/library/hacmp_docs.html

We assume the following prerequisites are met before starting the WebSphere configuration: - You have an HACMP cluster configured that consists of at least two systems which share a storage device.

- You have checked the prerequisites needed for IBM WAS ND V6 at:

At the time of writing this redbook, the officially supported configuration is running the Deployment Manager on HACMP/ES 5.1.

- You have an IP Alias or virtual host name.

- You have determined how you are going to configure WebSphere. Specifically, you have determined whether you are going to separate the binary files from the configuration files. You have two options:

You can put the binaries and configuration files on the shared disk.

You can put the binaries on a local disk and the configuration files on the shared disk.
