How to configure an OS client for permanent operability

Introduction
A minimum of two OS clients are required for permanent operability. A preferred server is
specified separately for each client, thus distributing the OS clients to the redundant OS
servers. This ensures that the process is continuously available even during a failover from a
faulty OS server to the redundant OS partner server.
