Power Off Procedure
If you wish to power down the subsystem, please follow these steps:
NOTE:
If you wish to power down the subsystem, please make sure that
no time-consuming processes, like a “logical drive parity” check or
a “background scrub,” are running.
Step 1.
Stop I/O access to the system.
Close your applications to stop all I/O accesses to the
subsystem. Please refer to the documentation that came
with your applications.
Step 2.
Flush the cache.
Locate the C_Dirty LED on the controller module to check
if there is still cached data in memory. Use the
Shutdown
Controller
firmware function to flush all cached data. This
prepares the RAID subsystem to be safely powered down.
Step 3.
Turn off the power.
Power off the subsystem using the power switch on each
PSU. Once the subsystem is powered down, other
devices/enclosures that are connected to the subsystem
can be sequentially powered down.
