NonStop Cluster Essentials Installation and Quick Start Guide

Installing NonStop Cluster Essentials on a Windows Console
Pre-Installation Considerations:
• If an older version of NonStop Cluster Essentials exists on the console, you must uninstall it
before installing a newer version of NonStop Cluster Essentials (see “Uninstall the Client
Component from a Windows Console” (page 35)).
NOTE: Before uninstalling the older version of NonStop Cluster Essentials, you should back
up your cluster database. From the NonStop Cluster Configuration Management main window,
click Export Database Configuration to perform the cluster database backup.
• If you are also using the NonStop I/O Essentials product, you can install that product either
before or after NonStop Cluster Essentials. However, you must use a compatible version of
NonStop I/O Essentials with NonStop Cluster Essentials, as older versions of NonStop I/O
Essentials will no longer function with newer versions of NonStop Cluster Essentials. The table
below shows the compatibility between the two products. If the NonStop Cluster Essentials
installer detects an unsupported version of NonStop I/O Essentials on the CMS, it will prompt
you to uninstall that version.
