2.10.9 Restart or halt the controller
When you want to turn the RAID system off, you must go through a regular shutdown procedure. Always follow the steps
below to instruct the controller restart or halt before powering off the RAID system.
1. Select System Management > Restart/Halt from the main menu.
2. (For redundant-controller system only) From the Controller ID drop-down menu, specify whether you want to restart
or halt ctla, ctlb, or Both Controllers.
3. From the Action drop-down menu, select Restart or Halt.
4. Once any external SAS JBOD enclosure is connected, the ‘Apply to all external enclosures’ checkbox will be
displayed. Check this checkbox to restart or halt all the enclosures at the same time.
5. Click Apply.
• When Restart is selected, the controller automatically restarts. Click Reconnect when boot up is complete.
• When Halt is selected, a confirmation prompt displays. Click Confirm, close the GUI, and power off the RAID
system.

your controller.
To make the settings effective, click Apply.
Note
3. For external enclosure firmware option, you can check the ‘Apply’ to all external enclosure'
option to apply the updating to all external enclosure at the same times.
3. After updating the firmware for external enclosures, it requires to restart both the controllers for
the RAID system and all external enclosures.
4. The RAID controller supports redundant flash chip for system firmware. Primary chips will be
updated first and the secondary chips later. Wait for the completion of firmware update of both
chips.
5. The redundant-controller RAID system supports uninterruptable firmware update (but it
depends on the compatibility of your running and new firmware, contact your system supplier to
know the compatibility). After updating the firmware to the flash chip one both controllers, one
controller will be restarted first and the other controller will be restarted later. During the restart,
the controller will take over the peer controller. However, for updating the firmware of external
enclosures, rebooting is still needed.
Enclosure Polling Period (second): Disabled (default)/1/2/5/10/30/60
(This option is only available for the controller equipped with an expansion port.)
By specifying the polling interval, the controller polls the external enclosure to acquire its status periodically. When
disabled, the controller cannot obtain the status of the enclosures.
GUI Refresh Rate (second): 5 (default)
By default, the GUI refreshes itself every 5 seconds. You can specify a new refresh rate. The range is from 2 to
15.
Memory Testing When Boot-Up: On
(default)
/Off
Select this option to enable or disable memory testing when controller boot-up.
Management Device for ln-band API: Off
(default)
/LUN ID(0~127)
Select this option to enable or assign LUN ID when user want to use ln-band API Utility.
Note
Faster GUI refresh rates may degrade the performance of controller.
