Shutting down controllers
Perform a shut down before you remove a controller module from an enclosure, or before you power off its enclosure for maintenance,
repair, or a move. Shutting down the storage controller in a controller module ensures that a proper failover sequence is used, which
includes stopping all I/O operations and writing any data in write cache to disk. If you shut down the storage controller in both controller
modules, hosts cannot access system data.
CAUTION: You can continue to use the CLI when either or both storage controllers are shut down, but some information
might not be available.
