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#
