2.3.8 Turning off the system
Before turning off the system, ensure that no processes are taking place such as
Regenerate Logical
Drive Parity
or
Media Scan
.
To turn off the system:
1. Close all applications to stop the I/O access to the system.
2. Flush the cache to clear the DRAM data. If the DRAM contains cached data, the Cache_Dirty LED
lights up in amber.
3. Flush all cached data using the controller’s shutdown function to prepare the RAID system for a
safe power shutdown. Refer to EonOne manual for details.
4. Once the cache is flushed, switch off the system.
