LSI 9300-xx Firmware Update

Hey Community,

If you are using an LSI 9300 HBA with FreeNAS or the soon-to-be TrueNAS CORE, you may experience some performance issues causing the controller to reset when using SATA HDDs.

After working with Broadcom, we’ve come up with a firmware update that is not available on their website that should resolve these controller reset issues. To resolve this issue for FreeNAS systems affected in the field, here are the instructions for updating the firmware to version

Please Note: This problem applies only to firmware versions below and Only affects SATA drives. SAS drives are not affected.


First, download the firmware .zip file included by clicking the Download button in the upper right corner of this resource.

Unzip the .zip file and go to the newly created firmware directory

Copy SAS9300_xx_IT.bin

cd to the directory you copied the firmware file

Run this command: sas3flash -o -f SAS9300_xx_IT.bin

Example output when flashing a 9300-8i:

root@freenas# sas3flash -o -f SAS9300_8i_IT.bin
