Programming the Flash Memory
The IIR controller normally comes ready to be installed into the computer motherboard
immediately. However, you may need to reprogram the RAID firmware that is located in
the flash memory of the IIR controller.
There are 2 options for programming the firmware, Firmware Update or Firmware
Recovery. Use the Firmware Update procedure to overwrite the existing firmware with a
new image (see
Appendix A.1
). Use the Firmware Recovery procedure to resolve
problems with the flash memory, for example, if the current firmware programmed in the
flash is unusable or if a previous firmware update was inadvertently interrupted (see
Appendix A.2
).
2.4
SCSI Termination
Termination is critical when connecting SCSI devices together. Connected SCSI devices
are typically called a SCSI bus, and termination is required at the each end of the SCSI
bus. Use a high-quality terminator at the end of the SCSI cable after the last device in the
bus to ensure proper termination.
The modular RAID on motherboard (MROMB) design lowers cost by utilizing the SCSI
controller and connectors that are integrated into the system’s motherboard. With
MROMB, termination occurs on the host SCSI controller.
