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 ensure that no
time-consuming processes, like “Regenerate Logical Drive Parity”
or a “Media Scan,” are taking place.
Step 1.
Stop I/O access to the system.
Close your applications running on the host computers to
stop all I/O access to the subsystem.
Step 2.
Flush the cache.
Locate the C_Dirty LED on the controller module to check
if there is still cached data in the memory. Use the
“Shutdown Controller” function in firmware 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.
