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 RAID system.
