Power Off Procedure
If you wish to power down the system, please follow these steps:
NOTE
If you wish to power down the system, please ensure that no time-consuming
processes, like “Regenerate Logical Drive Parity” or a “Media Scan,” are taking
place.
1. Stop I/O access to the system
Close your applications running on the host computers to stop all I/O access to
the system.
2. Flush the cache
Locate the C_Dirty LED (refer to
Controller LED for RAID Models) on the
controller module to check if there is still cached data in the DRAM (if the LED is
lid up in amber).
3. Use the Shutdown Controller function to flush all cached data (please refer
to the SANWatch manual)
4. Once the cache has been flushed, you may proceed to power down the
system.
