This guide is intended for administrators who need to set up, configure, and maintain clusters with SUSE® Linux Enterprise High Availability. For quick and efficient configuration and administration, the product includes both a graphical user interface and a command line interface (CLI). For performing key tasks, both approaches are covered in this guide. Thus, you can choose the appropriate tool that matches your needs.
