In this IBM Redpaper, we discuss how to set up clustered systems, using IBM® System Storage™ N3700 Model 2863-A20 as an example. This paper covers hardware setup, cluster node and configuration, and disk ownership in a clustered environment.
The guide provides step‑by‑step instructions for planning, installing, and configuring the IBM System Storage N3700 A20 clustered storage appliance. It covers hardware setup, cable connections, shelf ID configuration, and the initial cluster configuration wizard.
Key topics include hardware components, required tools, disk ownership rules, and detailed procedures for connecting Ethernet, console, and Fibre Channel ports, as well as attaching optional EXN2000 expansion shelves.
