You may need to restore default settings in the following cases:
When the firmware update procedure requires it.
When you need to reset the password to access the Unified Storage System
Restoring Default Settings
To restore default settings for Dual Controller models, follow these steps.
1.
Stop all host I/O’s.
2.
Save the current configuration using the “
Export NVRAM
” function.
3.
You may also want to make a list of the existing ID/LUN mapping information because the
default restoration will erase the ID/LUN mapping associations (e.g., which logical drive is
associated with which host ID/LUN)
4.
Remove Controller B from the chassis. Please refer to Removing the Controller.
5.
Power off the Unified Storage System.
6.
Press and hold the Restore Default button on Controller A. You may use a straightened
paper clip to press the button. While pressing the Restore Default button down, power on the
Unified Storage System.
7.
Keep pressing the Restore Default button until the Restore Default LED lights up than release
the Restore Default button.
8.
System default has been restored when the Controller Status LED changes the color from
amber
to
green
.
9.
Restore previous settings using the “
Import NVRAM from reserved space
“ or “
Restore
NVRAM from Files
” in the firmware. ID/LUN mapping will be restored.
*The Single Controller system’s restore default procedure is complete and for
Dual Controller
systems, please continue with the following procedures:
10. Power off the system.
11. Replace Controller A with Controller B (Controller B will be inserted into Controller A’s slot)
While leaving Controller B slot empty with Controller B in slot A, perform the above steps 1 to
8 to restore Controller B to default settings.
12. Put both Controller A and Controller B into their original positions and power up the system.

Controller Module(s)
WARNING
Controller firmware
MUST
be identical for proper functionality.
DO NOT
mix controller modules from different models. Each controller has a unique
ID which is applied to host port names. As the result, you may encounter SAN
problems with identical port names on multiple systems.
When removing a controller from a Single-Controller system, ensure that your
applications have been shut down beforehand.
