The document provides step-by-step instructions for shutting down and powering up a NetApp cluster mode system. It describes the process of: 1. Shutting down connected host machines, switches, and SAN components like controllers and disk shelves. 2. Powering up disk shelves first, then controllers, switches, and host machines after 5-10 minutes. 3. Entering commands like disabling the cluster, halting nodes, and enabling the cluster during shutdown and startup.
