NOTE:
Step 1. Stop I/O access to the system.
Stop all I/O access to the EonStor subsystem. Please refer to the
related documentation of your applications.
Step 2. Flush the cache.
Locate the C_Dirty LED on the back of controller module to check
if there is still cached data in memory. Use the Shutdown Controller
function to flush all cached data. This prepares the RAID subsystem
to be safely powered down.
Step 3. Turn off the power.
Turn off the power switches at the top of the rear panel of the
AR3016G. Once the subsystem has been powered down, other
devices that are connected to the subsystem may be powered down.
System is ready for I/Os.
