About 6 months ago I got a new HBA for one of my servers and went through a somewhat ridiculous process of flashing the firmware so that it only acts as an HBA... meaning no hardware RAID.
Unfortunately, I forgot to include a couple things I learned back then and brings us to the reason for this post.
Step by step:
Ignore all the installers that claim they can install from Linux or FreeBSD(I tested both. Windows is an unknown.).
Get yourself a USB drive and install FreeDOS.
dd if=FreeDOS-1.1-memstick-2-256MB.img of=/dev/sdz bs=512k
- Remount the disk
Mount the newly made USB drive and copy the following files to the root of the USB drive:
Boot from the USB drive and get to a DOS prompt.
- Erase most of the flash. Do not use erase level 7.
sas2flash -o -e 6
- Flash the firmware and BIOS updates:
sas2flash -o -f 2118it.bin -b mptsas2.rom
- Was the flash successful?
