Note
1. Contact your RAID system supplier before updating the firmware.
DO NOT udpate the firmware unless you fully understand what a
version of firmware will do. One of the general rules is not to
update the firmware using an older version. Otherwise, the
system might not work properly.
2. When updating the firmware, boot code and external enclosure
firmware, do not perform any actions in GUI or power off the
controller.
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.
4. After updating the firmware for external enclosures, it requires to
restart both the controllers for the RAID system and all external
enclosures.
5. 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.
6. 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.
