            Subsystem: Mellanox Technologies Device 0014


        2. Download the ISO image to your host.
            The image’s name has the format MLNX_OFED_LINUX-<ver>-<OS label><CPU arch>.iso
            You can download and install the latest OpenFabrics Enterprise Distribution (OFED) software package available via the NVIDIA web site at nvidia.com/en-us/networking → Products → Software → InfiniBand Drivers → NVIDIA MLNX_OFED
      1. Scroll down to the Download wizard, and click the Download tab.
      2. Choose your relevant package depending on your host operating system.
      3. Click the desired ISO/tgz package.
      4. To obtain the download link, accept the End User License Agreement (EULA).

        3. Use the Hash utility to confirm the file integrity of your ISO image. Run the following command and compare the result to the value provided on the download page.

    SHA256 MLNX_OFED_LINUX-<ver>-<OS label>.iso


    Installing MLNX_OFED

    Installation Script

    The installation script, mlnxofedinstall, performs the following:

    • Discovers the currently installed kernel
    • Uninstalls any software stacks that are part of the standard operating system distribution or another vendor's commercial stack
    • Installs the MLNX_OFED_LINUX binary RPMs (if they are available for the current kernel)
    • Identifies the currently installed InfiniBand and Ethernet network adapters and automatically upgrades the firmware
      Note: To perform a firmware upgrade using customized firmware binaries, a path can be provided to the folder that contains the firmware binary files, by running --fw-image-dir. Using this option, the firmware version embedded in the MLNX_OFED package will be ignored.
      Example

      ./mlnxofedinstall --fw-image-dir /tmp/my_fw_bin_files

    If the driver detects unsupported cards on the system, it will abort the installation procedure. To avoid this, make sure to add --skip-unsupported-devices-check flag during installation.

    Usage

    ./mnt/mlnxofedinstall [OPTIONS]

    The installation script removes all previously installed OFED packages and re-installs from scratch. You will be prompted to acknowledge the deletion of the old packages.

    Pre-existing configuration files will be saved with the extension “.conf.rpmsave”.


    • If you need to install OFED on an entire (homogeneous) cluster, a common strategy is to mount the ISO image on one of the cluster nodes and then copy it to a shared file system such as NFS. To install on all the cluster nodes, use cluster-aware tools (suchaspdsh).
    • If your kernel version does not match with any of the offered pre-built RPMs, you can add your kernel version by using the “mlnx_add_kernel_support.sh” script located inside the MLNX_OFED package.

      On Redhat and SLES distributions with errata kernel installed there is no need to use the mlnx_add_kernel_support.sh script. The regular installation can be performed and weak-updates mechanism will create symbolic links to the MLNX_OFED kernel modules.

      If you regenerate kernel modules for a custom kernel (using --add-kernel-support), the packages installation will not involve automatic regeneration of the initramfs. In some cases, such as a system with a root filesystem mounted over a ConnectX card, not regenerating the initramfs may even cause the system to fail to reboot.

      In such cases, the installer will recommend running the following command to update the initramfs:

      dracut -f

      On some OSs, dracut -f might result in the following error message which can be safely ignore.

      libkmod: kmod_module_new_from_path: kmod_module 'mdev' already exists with different path


      The “mlnx_add_kernel_support.sh” script can be executed directly from the mlnxofedinstall script. For further information, please see '--add-kernel-support' option below. 

      On Ubuntu and Debian distributions drivers installation use Dynamic Kernel Module Support (DKMS) framework. Thus, the drivers' compilation will take place on the host during MLNX_OFED installation.
      Therefore, using "mlnx_add_kernel_support.sh" is irrelevant on Ubuntu and Debian distributions.

      Example: The following command will create a MLNX_OFED_LINUX ISO image for RedHat 7.3 under the /tmp directory.

      # ./MLNX_OFED_LINUX-x.x-x-rhel7.3-x86_64/mlnx_add_kernel_support.sh -m /tmp/MLNX_OFED_LINUX-x.x-x-rhel7.3-x86_64/ --make-tgz
      Note: This program will create MLNX_OFED_LINUX TGZ for rhel7.3 under /tmp directory.
      All Mellanox, OEM, OFED, or Distribution IB packages will be removed.

    • The script adds the following lines to /etc/security/limits.conf for the userspace components such as MPI:
      • * soft memlock unlimited
      • * hard memlock unlimited
        • These settings set the amount of memory that can be pinned by a userspace application to unlimited. If desired, tune the value unlimited to a specific amount of RAM.


    For your machine to be part of the InfiniBand/VPI fabric, a Subnet Manager must be running on one of the fabric nodes. At this point, OFED for Linux has already installed the OpenSM Subnet Manager on your machine.

    For the list of installation options, run:

    ./mlnxofedinstall --h

    Installation Procedure

    This section describes the installation procedure of MLNX_OFED on NVIDIA adapter cards. 

    1. Log in to the installation machine as root.
    2. Mount the ISO image on your machine. 

      host1# mount -o ro,loop MLNX_OFED_LINUX-<ver>-<OS label>-<CPU arch>.iso /mnt
    3. Run the installation script.

      /mnt/mlnxofedinstall
      Logs dir: /tmp/MLNX_OFED_LINUX-x.x-x.logs
      This program will install the MLNX_OFED_LINUX package on your machine.
      Note that all other Mellanox, OEM, OFED, RDMA or Distribution IB packages will be removed.
      Those packages are removed due to conflicts with MLNX_OFED_LINUX, do not reinstall them.

      Querying Mellanox devices firmware ...

      For unattended installation, use the --force installation option while running the MLNX_OFED installation script:
      /mnt/mlnxofedinstall --force

      MLNX_OFED for Ubuntu should be installed with the following flags in chroot environment:
      ./mlnxofedinstall --without-dkms --add-kernel-support --kernel <kernel version in chroot> --without-fw-update --force
      For example:
      ./mlnxofedinstall --without-dkms --add-kernel-support --kernel 3.13.0-85-generic --without-fw-update --force
      Note that the path to kernel sources (--kernel-sources) should be added if the sources are not in their default location.

      In case your machine has the latest firmware, no firmware update will occur and the installation script will print at the end of installation a message similar to the following:
      Device #1:
      ----------
      Device Type: ConnectX-X
      Part Number: MCXXXX-XXX
      PSID: MT_<version>
      PCI Device Name: 0b:00.0
      Base MAC: 0000e41d2d5cf810
      Versions: Current Available
      FW XX.XX.XXXX
      Status: Up to date

      In case your machine has an unsupported network adapter device, no firmware update will occur and one of the error messages below will be printed. Please contact your hardware vendor for help with firmware updates.

      Error message #1:
      Device #1:
      ----------
      Device Type: ConnectX-X
      Part Number: MCXXXX-XXX
      PSID: MT_<version>
      PCI Device Name: 0b:00.0
      Base MAC: 0000e41d2d5cf810
      Versions: Current Available
      FW XX.XX.XXXX
      Status: No matching image found

      Error message #2:
      The firmware for this device is not distributed inside NVIDIA driver: 0000:01:00.0 (PSID: IBM2150110033)
      To obtain firmware for this device, please contact your HW vendor.

    4. Case A: If the installation script has performed a firmware update on your network adapter, you need to either restart the driver or reboot your system before the firmware update can take effect. Refer to the table below to find the appropriate action for your specific card.

      Action \ AdapterDriver RestartStandard Reboot (Soft Reset)Cold Reboot (Hard Reset)
      Standard ConnectX-4/ConnectX-4 Lx or higher-+-
      Adapters with Multi-Host Support--+
      Socket Direct Cards--+

      Case B: If the installations script has not performed a firmware upgrade on your network adapter, restart the driver by running: “/etc/init.d/openibd restart”.

    5. (InfiniBand only) Run the hca_self_test.ofed utility to verify whether or not the InfiniBand link is up. The utility also checks for and displays additional information such as:
      • HCA firmware version
      • Kernel architecture
      • Driver version
      • Number of active HCA ports along with their states
      • Node GUID
        For more details on hca_self_test.ofed, see the file docs/readme_and_user_manual/hca_self_test.readme.

    After installation completion, information about the OFED installation, such as prefix, kernel version, and installation parameters can be retrieved by running the command /etc/infiniband/info. Most of the OFED components can be configured or reconfigured after the installation, by modifying the relevant configuration files. See the relevant chapters in this manual for details.
    The list of the modules that will be loaded automatically upon boot can be found in the /etc/infiniband/openib.conf file.

    Installing OFED will replace the RDMA stack and remove existing 3rd party RDMA connectors.

    Installation Results

    Software

    • Most of MLNX_OFED packages are installed under the “/usr” directory except for the following packages which are installed under the “/opt” directory:
      • fca and ibutils
      • iproute2 (rdma tool) - installed under /opt/Mellanox/iproute2/sbin/rdma
    • The kernel modules are installed under
      • /lib/modules/`uname -r`/updates on SLES and Fedora Distributions
      • /lib/modules/`uname -r`/extra/mlnx-ofa_kernel on RHEL and other RedHat like Distributions
      • /lib/modules/`uname -r`/updates/dkms/ on Ubuntu

    Firmware

    • The firmware of existing network adapter devices will be updated if the following two conditions are fulfilled:
      • The installation script is run in default mode; that is, without the option ‘--without- fw-update’
      • The firmware version of the adapter device is older than the firmware version included with the OFED ISO image
        Note: If an adapter’s Flash was originally programmed with an Expansion ROM image, the automatic firmware update will also burn an Expansion ROM image.
    • In case your machine has an unsupported network adapter device, no firmware update will occur and the error message below will be printed.
      "The firmware for this device is not distributed inside NVIDIA driver: 0000:01:00.0 (PSID: IBM2150110033)
      To obtain firmware for this device, please contact your HW vendor."

    Installation Logging

    While installing MLNX_OFED, the install log for each selected package will be saved in a separate log file.

    The path to the directory containing the log files will be displayed after running the installation script in the following format:

    Example:

    Logs dir: /tmp/MLNX_OFED_LINUX-4.4-1.0.0.0.IBMM2150110033.logs

    Driver Load Upon System Boot

    Upon system boot, the NVIDIA drivers will be loaded automatically.

     To prevent the automatic load of the NVIDIA drivers upon system boot:

    1. Add the following lines to the "/etc/modprobe.d/mlnx.conf" file. 

      blacklist mlx5_core
      blacklist mlx5_ib
    2. Set “ONBOOT=no” in the "/etc/infiniband/openib.conf" file.

    3. If the modules exist in the initramfs file, they can automatically be loaded by the kernel. To prevent this behavior, update the initramfs using the operating systems’ standard tools.

      Note: The process of updating the initramfs will add the blacklists from step 1, and will prevent the kernel from loading the modules automatically.

      When using an operating system different than RHEL or SLES, or you have installed a kernel that is not supported by default in MLNX_OFED, you can use the mlnx_add_kernel_support.sh script to build MLNX_OFED for your kernel.
      The script will automatically build the matching group RPM packages for your kernel so that you can still install MLNX_OFED via yum.
      Please note that the resulting MLNX_OFED repository will contain unsigned RPMs, therefore, you should set 'gpgcheck=0' in the repository configuration file.

    2. Install the desired group.
