Restoring Default System Settings
NOTE
Restoring default settings is a last-resort function. All configurations, such as
parameters and host LUN mappings, will be erased.
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 storage system.
Restoring Default Settings
To restore default settings for dual-controller models, follow these steps.
1. Stop all host I/Os.
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 storage system.
6. Press and hold the Restore Default button (indicated by the blue arrow) on
Controller A. You may use a straightened paper clip to press the button. While
pressing the Restore Default button down, power on the storage system.
7. When the “Restore Def.” LED (indicated by the black arrow) lights up and the
“Default Restored” firmware event message appear, you may release the
Restore Default button (the system default has been restored).
