Flashing the LSI-9211 to IT mode using an EFI shell

- 3 min read

I’ve been building a new storage-oriented server for a while now and have yet again decided to go with (3 +1 backup) LSI 9211 raid controllers.

The reason I keep going for these specific raid controllers is quite simple. The card can theoretically support (8x500MB) 4GB/s in throughput divided over 8 drives (2x SFF-8087) which is near the maximum for consumer hard drives.

Using 3 of these will allow me to use 24 drives in a single chassis without an expander whilst getting pretty good performance. The fourth card that I got, and flashed, is simply used as a backup or debug card in case of any errors.

Downloading the files

Before we can start flashing we will need to download some files. The table below lists all the files with a brief description of what we’ll use them for.

File Description
EFI flashing utility Flashing utility
EFI ROM image Card ROM file
SAS2008 Firmware IR and IT firmware for the 9211

Prepping the flash drive

Make sure that you have a flash drive that is 32GB or smaller and that it is formatted as FAT32. Next, we’ll add the following files to the root of the flash drive:

  • Installer_P20_for_UEFI/sas2flash_efi_ebc_rel/sas2flash.efi
  • UEFI_BSD_P20/uefi_bsd_rel/Signed/x64sas2.efi
  • 9210-8i_Package_P20_IR_IT_FW_BIOS_for_MSDOS_Windows/sasbios_rel/mptsas2.rom
  • 9210-8i_Package_P20_IR_IT_FW_BIOS_for_MSDOS_Windows/Firmware/HBA_9210_8i_IT/2108it.bin

Flashing with EFI

Because we are going to flash using EFI we don’t really need anything besides the built-in EFI shell from our motherboard. Simply insert the flash drive and go into the BIOS or use the “select boot device” functionality to select the EFI shell:

"picture of the monitor showing boot options"
selecting the EFI shell boot option

After the shell has booted successfully you can use the map command to see all available devices. In the image below you’ll see that my flash drive is listed as fs1:

A list of devices in the EFI shell
a list of devices note that `fs1` is my flash drive

To switch into the drive simply enter the drive name on the command line followed by a semicolon:


Next, we’ll determine that our adapters are available and we will simultaneously take note of their identifier, we can do so by issuing the following command:

sas2flash.efi -listall

"list of adapters"
a list of adapters, I flash them one at a time so I only have card '0' available to me

Next, we can empty the current firmware with the following command:

sas2flash.efi -o -e 6

Showing the result of the erasing action
bye, bye firmware 😢

Now we’ll simply flash the new (IT-mode) firmware on it with the following command:

sas2flash.efi -o -f 2108it.bin -b mptsas2.rom

result of flashing in the EFI shell
1 card down, 3 more to go!

Wait patiently until the operations have completed. Note that it might seem like the steps repeat, just wait until it is completely done and exits back to the shell by itself.

Multiple cards and conclusion

You can rerun the commands for different cards (by adding -c x where x is the card number from listall) or by simply physically switching the current one out for a different one.

That’s all there is too it, if you need any help feel free to hit me up!
