SUSE Linux Enterprise High Availability Extension 12 SP5
Administration Guide
Abstract#
This guide is intended for administrators who need to set up, configure, and maintain clusters with SUSE® Linux Enterprise High Availability Extension. For quick and efficient configuration and administration, the High Availability Extension includes both a graphical user interface (GUI) and a command line interface (CLI). For performing key tasks, both approaches (GUI and CLI) are covered in detail in this guide. Thus, administrators can choose the appropriate tool that matches their needs.
