Shutdown - HP P2000 G3 Cli Reference Manual

shutdown

Description Shuts down the Storage Controller in a controller module. This 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 the Storage Controller in each controller module is shut down, hosts cannot access the
system's data. Perform a shut down before removing a controller module or powering down the
system.
CAUTION: You can continue to use the CLI when either or both Storage Controllers are shut down,
but information shown might be invalid.
