NOTE:
If you wish to power down the Galaxy 16i subsystem, please
ensure that no time-consuming processes, like a "logical drive
parity" check or a "background scrub," are running.
1. Stop IO access to the system
Use the software that is provided on the host computer to stop
all IO accesses to the Galaxy 16i subsystem. Please refer to
the user manual that came with your host computer.
2. Disconnect the host
The host must be disconnected from the subsystem. To do
this, disconnect the FC cables from both the host and the
Galaxy 16i subsystem.
3. Flush the cache
Use the "Shutdown Controller" function to flush all cached
data. This prepares the RAID subsystem to be powered down.
4. Turn off the power
Turn off the power switches at the top of the rear panel of the
Galaxy 16i RAID subsystem. Once the RAID subsystem has
been powered down, other devices that are connected to the
subsystem may be powered down.
