15 System Functions - Upgrading Firmware
15.1 Upgrading Firmware
The RAID controller’s firmware resides in flash memory that can be updated through the COM
port, LAN port, or via In-band SCSI/Fibre.
15.1.1 Background RS-232C Firmware Download: Single Controller
Host I/Os will not be interrupted during the download process. After the download process is
completed, user should find a chance to reset the controller for the new firmware to take
effect.
15.1.2 Note for Redundant Controller Firmware Upgrade:
A controller used to replace a failed unit in a dual-controller system is often running a newer
release of firmware version. To solve the contention, make sure the firmware on a replace-
ment controller is downgraded to that running on the surviving controller.
15.2 Upgrading Firmware Using RAIDWatch Manager
15.2.1 Establish the In-band SCSI connection in RAIDWatch Manager
Please refer to RAIDWatch User's Manual for details on establishing the management session
for RAIDWatch Manager.
15.2.2 Upgrade Both Boot Record and Firmware Binaries
1. Connect to the RAID system locally or from a remote computer using RAIDWatch Man-
ager. While connected to the RAID system, there will be icon(s) with IP address specified
on the left of the menu screen. Select by double-clicking the icon of the RAID system
which firmware is to be upgraded. Select the “Configuration Parameters” icon and then
select the “System” tab. Single-click the “Download FW+BR” check circle. Click the Apply
button to proceed. A message prompt should display. Click Yes and then a file location
prompt will appear.
2. Provide the boot record binary filename, the RAIDWatch Manager will start to download
the boot record binary to the controller.
3. After the boot record download is completed, provide the firmware filename to the RAID-
Watch Manager. It will start to download the firmware to RAID controller.
4. Shutdown the application server(s) or stop the application(s) which are accessing the
RAID, then reset the RAID subsystem/controller in order to use the new downloaded firm-
ware. With firmware release 3.21 and above, host I/Os will not be interrupted by the
download process. Users may find a chance to stop host I/Os and reset the controller for
new firmware to take effect.

NOTICE!
• Allow the downloading process to finish. Do not reset or turn off the computer or the
controller while it is downloading the file. Doing so may result in an unrecoverable error
that requires the service of the manufacturer.
• When upgrading the firmware, check the boot record version that comes with it. If the
boot record version is different from the one installed on the surviving controller previ-
ously, the new boot record binary must be installed.
• The COM 2 serial port cannot be used to download firmware.
