If you are using LSI SAS 2008 based HBA/RAID cards such as the LSI 9211-8i FreeNAS recommend run in IT (Initiator Target) mode. Don’t use cards in IR (Integrated RAID) mode.
For update firmware and BIOS check current firmware version with command:
sas2flash -list
Example output:
(in my case card already in IT mode)
Firmware should be at-least 20.00.07.00 and BIOS should be 7.39.02.00
Download Firmware and BIOS
Firmware and bios download here: https://docs.broadcom.com/docs-and-downloads/host-bus-adapters/host-bus-adapters-common-files/sas_sata_6g_p20/9210-8i_Package_P20_IR_IT_FW_BIOS_for_MSDOS_Windows.zip
Then download flasher for UEFI: https://docs.broadcom.com/docs-and-downloads/host-bus-adapters/host-bus-adapters-common-files/sas_sata_6g_p20/Installer_P20_for_UEFI.zip
You need sas2flash.efi from Installer_P20_for_UEFI.zip and 2108it.bin aswell as mpt2sas.rom from 9210-8i_Package_P20_IR_IT_FW_BIOS_for_MSDOS_Windows.zip
Create bootable USB stick. Use Rufus software.
Put those 3 files on a fat32 USB stick load into UEFI Shell get to the folder with the 3 files and run:
sas2flash.efi -f 2108it.bin -b mptsas2.rom
Then run:
sas2flash.efi -list
And confirm that firmware is 20.00.07.00 and BIOS is 7.39.02.00
In case if you have more than 1 RAID card for example 2, you can update BIOS and firmware simultaneously:
sas2flash -listall
Output:
then:
sas2flash.efi -c 0 -f 2108it.bin -b mptsas2.rom sas2flash.efi -c 1 -f 2108it.bin -b mptsas2.rom
-c specifies which card you want to target
