flashing controller firmware

storcli, drivers, firmware & psoc can all be downloaded from the broadcom support site.

your storcli, driver & firmware’s revision code (pxx number) should match - p37 in this example. the psoc version can & will differ.

example:

  • storcli: STORCLI_SAS3.5_P37.zip
  • driver: ItSas35_Windows11_Windows_Server_2022_2025_P37.zip
  • firmware: 9500_16e_Pkg_P37_MIXED_FW_BIOS_UEFI.zip
  • psoc: 1.32_PSoC_Catalog_Firmware_HBA.zip

overview

  1. upgrade storcli to newest version

    just download the newest storcli for your hba. for the 9500 series this will be storcli sas3.5. unzip & start using the new storcli64.exe.

  2. upgrade hba driver to newest version and reboot

    also not rocket science. open the driver zip file, extract the folder for your operating system, Win11_25H2_x64 in this case. open device manager, go to the hba & click update driver. use the option browse my computer for drivers and select the folder you just unzipped. device manager driver select

  3. upgrade hba bios

    the bios needs to be updated before the fw. you’ll find it in the firmware zip file in the SAS35BIOS_UEFI_SAS3.5_IT_X64_ARM directory. make sure to use the one that says x64 bios (ignore the arm uefi one)

    storcli64.exe /c0 download bios file=IT_HBA_X64_BIOS_PKG_E6.rom

    this will take about 30 seconds to complete, your hba will continue work

  4. upgrade hba fw

    the firmware is can be found in the zip file under the firmware directory. there you’ll find both HBA_9500-16e_SAS_SATA_Profile.bin and HBA_9500-16e_Mixed_Profile.bin.

    storcli64.exe /c0 download file=HBA_9500-16e_SAS_SATA_Profile.bin

    this can will take a few minutes to complete. do not panic if the command appears frozen, just be patient.

  5. upgrade psoc if available - todo
