2.10.1 Restoring to factory settings
To clear the NVRAM or hard disk configurations, do the following:
1. Select the “Erase configurations on NVRAM” or the “Erase configurations on HDD(s)” option to clear all
configurations made on NVRAM or hard disks.
2. When the “Erase configurations on HDD(s)” option is selected, specify the hard disks or a hard disk to clear the
configurations on it.
3. Click the Apply button, and the erase configuration message appears. Click Confirm to restore factory default
values.
2.10.2 NVRAM configuration
The controller’s configurations are stored in either NVRAM or hard disk(s) depending on configuration types. The
following options allows you to manage the configuration data.
Save the NVRAM configuration to HDD(s)
Specify this option to save the NVRAM configuration data to a hard disk or all hard disks.
This option enables or disables the auto write-through function for the following four types of events.
1. Controller Failure
2. Battery Backup Module Failure
3. Power Supply Unit Failure
4. Fan Failure
5. UPS Failure
When events are detected with a specified type, both the cache on the controller and disk will be automatically set
as write-through. After the failure or warning condition is removed, the cache settings will be restored to your
original configuration.
Path Failover Alert Delay (min): 5 (default)
When a path failover occurs, the controller will send out warning events to notify users after the specified delay
time (in minutes). The range is between 0 and 60.
Note
1. The “Erase configurations on HDD(s)” option will be available only when hard disks are in
foreign, conflict, or unknown state.
2. After the erase command is applied to NVRAM, the controller will restart immediately.
