LSI SAS Controller Flashing (2020 Update)

 For flashing an LSI-based SAS controller in 2020, especially on newer hardware, can be challenging.  Many of the resources/guides are many years old and were written before UEFI support.

I recently needed to re-flash two 9211 controllers and found these helpful

Mount USB and Flash Card:

  • Mount fs0  (fs0 = USB drive alias, yours may be different.  Use devices -b or map-b to see list)
  • fs0:
  • dir
  • Sas2flsh.efi -listall
  • sas2flash.efi -o -e 6
  • sas2flash.efi -o -f image.bin -b mptsas2.rom

Reprogram card address:

sas2flsh -o -sasadd 500605b0xxxxxxx  

(x = numbers for card SAS address, can be found on back of card)

reset   (reboot system)

Update Intel NIC Firmware

 I needed to update the firmware on some Intel X540-T2 cards that I had gotten for my homelab.  The cards didn't appear to have been updated in some time. https://downloadcenter.intel.com/download/29137/Ethernet-Intel-Ethernet-Connections-Boot-Utility-Preboot-Images-and-EFI-Drivers?product=58954 After downloading the latest firmware from Intel, I was struggling on the bootutil update syntax.  I came across this blog post that was quite helpful. https://calvin.me/how-to-update-intel-nic-firmware I also found this Intel support article that broke down the syntax and options for the bootutil command. https://www.intel.com/content/www/us/en/support/articles/000005790/software.html My cards had both the PXE and UEFI firmware, so I had to use the following: bootutil64e.efi -UP=PXE+EFI -ALL -File=BootIMG.FLB
