This article explains how to downgrage the firmware and the Bios into a DOS environment using an LSI HBA.
In the following example, an LSI 9211 8i is used with the firmware 8.00.00.00-IT. The firmware will be downgraded to 7.00.00.00-IT.
The DOS environment should already be provided via a bootable USB stick.
IMPORTANT: The server can not be restarted during the process!
Preparations
Step 1: The appropriate package must be downloaded from the LSI download page and unpacked.
The most important information data is:
- sas2flsh - The actual flash tool
- mptsas2.rom - The BIOS Image
- 2118IT.BIN / 2118IR.BIN - The firmware, first as an Initiator Target then as an Integrated Raid version
Steps
After the server has booted in the DOS environment the old firmware is deleted:
sas2flsh -o -e 6
Now the new firmware can be loaded:
sas2flsh -o -f 2118IT.BIN
And last, but not least, the BIOS:
sas2flsh -o -b mptsas2.rom
Now the server can be restarted and the corresponding firmware version should appear.
