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.
New releases of the firmware are available in the form of a DOS file
in the "pub" directory of Infortrend’s FTP site or on a 3.5" diskette.
The file available at the FTP site is usually a self-extracting file that
contains the following:
FW30Dxyz Firmware Binary (where "xyz" refers to the firmware
version)
B30Buvw Boot Record Binary (where "uvw" refers to the boot
record version)
README.TXT Read this file first before upgrading the
firmware/boot record. It contains the most up-todate
information which is very important to the
firmware upgrade and usage.
These files must be extracted from the compressed file and copied to
a directory in boot drive.
New Features Supported with Firmware 3.21
Background RS-232 Firmware Download:
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.
Redundant Controller Rolling Firmware Upgrade:
When download is performed on a dual-controller system, firmware
is flashed onto both controllers without interrupting host I/Os.
After the download process is completed, the Primary controller will
reset and let the Secondary take over the service temporarily. When
the Primary comes back on-line, the Secondary will hand over the
workload and then reset itself for the new firmware to take effect.
