This guide will outline the steps to flash a PERC H200 with LSI-9211-8i firmware to IT mode to allow direct disk access on an R710. This is helpful for situations where direct disk access is preferred over a RAID configuration, for instance, for use with a FreeNAS installation.
There’s a guide techmattr put together here that covers most of these steps, but I found it was missing a couple of details. These steps should ensure that your drives remain available for use as a BIOS boot device.
The steps to complete are:
Prepare boot media:
- Get yourself a USB flash drive, just about any size will do.
- Download Rufus to prepare the drive for use as FreeDOS boot media.
- Open Rufus, select your flash drive, choose FreeDOS as your boot selection, and click START
- Techmattr has complied most of the files you will need, (and more) at the link here. Simply extract this zip to the root of your flash drive.
- Additionally, to preserve the functionality to boot from your drives, you’ll need the LSI-9211-8i BIOS rom, available here. Under the
sasbios_reldirectory, you’ll find
mptsas2.rom. Copy this file to the root of your flash drive.
Flash the firmware:
Insert your flash drive in your R710, and boot from it. At the DOS prompt, run the following commands:
sas2flsh.exe -c 0 -listMake a note of the SAS Address listed.
megarec.exe -writesbr 0 sbrempty.bin
megarec.exe -cleanflash 0When this is complete, reboot your system!
sas2flsh.exe -o -f 6GBPSAS.fwWhen compete, reboot again.
sas2flsh.exe -o -f 2118it.bin -b mptsas2.rom
s2fp19.exe -o -sasadd YOUR_SAS_ADDRESSreplace YOUR_SAS_ADDRESS with the actual SAS Address value you wrote down previously. Omit any dashes.
