4.3.2 Shutting Down the SMs
You may need to shut down one or both SM modules when you plan to
power down the whole EF2800 system. This shuts down both the
storage manager and the LAN Subsystem on the SM module and
ensures that any data in the write-back cache is written to disk.
If you shut down both SM modules, you will lose access to SAM and
users will lose access to data. To restart the SM modules, you must first
turn off the power, then turn the power back on.
You should shut down both SM modules when you need to power down
the whole system for maintenance, repair, or a move. We strongly
recommend that you shut down the SM modules gracefully using
Shutdown to ensure that the write-back cache is written to disk. Do not
just turn off the power.
To shut down the SMs:
1. In SAM, select
Manage EF2800
>
Manage Modules
>
Shutdown/
Restart
. The Shutdown/Restart page displays.
2.
In the Shutdown SMs panel, select whether you want to shut down
one or both SM modules
