Shutting Down an Appliance
To ensure preservation of data on the REO Appliance, you should
not
turn off the appliance using the power
button; you should use the Shut Down option in the REO GUI. If you are setting up a new appliance and you
did not complete the steps in the proper order or power was automatically enabled, you might not have access
to the Shut Down option in the REO GUI.
If you have access to the REO GUI, complete the following steps.
1
Make sure that none of the initiators (servers) have active connections with the REO Appliance.
2
In the REO GUI, under
System Menu
, click
Maintenance
.
3
In the
System Maintenance
page, under
Shut Down/Restart
, click the applicable button.
If you want to shut down the appliance briefly and then automatically turn it back on, click
Restart
.
When the confirmation message appears, click
OK
to continue. Wait several minutes before you log
back on to the GUI.
If you want to shut down the appliance and leave the power off, click
Shut Down
. When the
confirmation message appears, click
OK
to continue. Wait several minutes before you perform any
maintenance on the REO Appliance.
If you do
not
have access to the REO GUI, complete the following steps.
1
Press and release the power button or switch on the front of the appliance quickly (1 second) to initiate a
graceful software-system shutdown process.
2
Wait up to 1 minute to see if the appliance responds.
The LED for power will turn off after the shutdown process is finished.
3
If the appliance does not shut down after the first attempt, try repeating step 1 and step 2 a second time.
Warning:
Pressing and holding the power button or switch for 4 seconds, or more, causes an immediate
hardware-shutdown that might result in the loss of data on the REO appliance if there are any active read-,
write-, or management-operations. Whenever possible, turn off the appliance using the REO GUI or the
graceful shutdown method described earlier. If you must use the immediate hardware-shutdown method,
make sure that you first stop all host- and management-server-related activity.
Click Maintenance.
