Installing MLNX_OFED

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
          

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.

• 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.

  Warning

  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.

  Warning

  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:

  Copy

  Copied!

              
  
              
  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.

  Warning

  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.

• 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.

   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 \ Adapter	Driver Restart	Standard 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.

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
        

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.

   Copy

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.

NVIDIA provides OFED packages to be installed on common operating systems. These packages are provided as binaries, and NVIDIA provided full support for them. This model is now referred to as "Primary support".

Starting OFED 5.6, NVIDIA is introducing a new support model for OFED used on open source community operating systems. The goal of this new support model is to enable customers to use community-maintained variants of the Linux operating system, without being limited to major distributions that NVIDIA provides primary support for.

In the community model, there is shared responsibility between NVIDIA and customers choosing to use community operating systems in their environment. NVIDIA owns basic validation for the operating systems, so that customers know they can expect OFED to work. Customers are responsible for building their own packages and binaries (based on source code and build instructions detailed below), and can also choose to deploy parts of OFED instead of the whole package.

In case of issues, for customers that are entitled for NVIDIA support (e.g. customers who have an applicable support contract), NVIDIA will do the best effort to assist, but may require the customer to work with the community to fix issues that are deemed to be caused by the community breaking OFED, as opposed to NVIDIA owning the fix end to end.

Overall, the following should be noted when running OFED on the community-supported operating systems:

• NVIDIA will perform sanity testing of OFED on community supported OSs

• NVIDIA will declare which kernel versions were tested (min/max), based on mainstream kernel (kernel.org) versions

• NVIDIA will not ship binaries/installation packages for community-supported OSs

• Customers will use source code of OFED and build guidance and will need to build their own binaries & installation packages

• Customers will be able to pick and choose the parts of OFED they deploy (e.g., drivers only, user tools only, and so forth)

• In case of bug reports, customers may be asked to reproduce on a primary-supported distribution (such as RHEL) in order to have support

• If issues are deemed specific to the community OS (e.g., if an OS deviates from mainstream in a way that breaks OFED), it is the customer’s responsibility to work with the community to fix it

Below are the instructions how to build OFED from the sources provided by NVIDIA.

Installing OFED on Community Operating Systems

1. Download sources from https://network.nvidia.com/products/infiniband-drivers/linux/mlnx_ofed

   1. Scroll down to the and click the "Download" tab.

   2. Choose the relevant package, depending on the host operating system (the package format is what really matters (rpm/deb)).

   3. Download the desired tgz SOURCE package (e.g., MLNX_OFED_SRC-<debian?>-<ver>.tgz)

2. Unpack the tarball.

   Copy

   Copied!

               
   
               
   tar -xzf MLNX_OFED_SRC-<debian?>-<version>.tgz
           

3. Go to the extracted directory.

   Copy

   Copied!

               
   
               
   cd MLNX_OFED_SOURCE-5.6-x.x.x.x
           

4. Run the installation script with the relevant options.

   Copy

   Copied!

               
   
               
   ./install.pl <option 1> <option 2> .
           

   Use "./install.pl --help" to see all the options and choose the desired option. For example: "./install.pl --all" should build and install all the default packages.

5. While running install.pl, the script may fail on missing dependencies. Those dependencies should be installed manually before running install.pl again.

Proprietary Packages

The installation procedure does not install proprietary packages—propriety packages should be installed upon request.

List of closed source proprietary packages:

• Clusterkit

• DPCP

• hcoll

• Sharp

• ibutils2

• opensm

Today the only way to install these packages is by using an already-built rpm/deb from a similar primary operating system.

The following table maps the community OSs that are most similar to Primary OSs based on internal testing:

Creating Metapackages and Installing OFED on Multiple Servers (RPM-Based Systems)

By building the packages using install.pl, the RPMs will be created under /tmp/OFED-internal-5.6-x.x.x/RPMS/<OS>/<arch>/

1. List the packages that will be installed by running the following:

   Copy

   Copied!

               
   
               
   /tmp/OFED-internal-5.6-x.x.x/install.pl--all -p
           

2. Create working directories.

   Example:

   Copy

   Copied!

               
   
               
   mkdir -p /tmp/OFED_topdir/SOURCES/<rpmname>-<version>
   mkdir -p /tmp/OFED_topdir/SPECS
   mkdir -p /tmp/OFED_topdir/BUILD
   mkdir -p /tmp/OFED_topdir/SRPMS
   mkdir -p /tmp/OFED_topdir/RPMS
           

   For --all option it used to set rpmname as mlnx-ofed-all
   OFED will be set to the current GA version being used.

3. Create a new XML file under /tmp/OFED_topdir/comp.xml that contains all the required packages.
   Example:

   Copy

   Copied!

   echo <rpmname>-<version> > /tmp/OFED_topdir/SOURCES/<rpmname>-<version>/<rpmname>-release
   cd /tmp/OFED_topdir/SOURCES
   tar czf <rpmname>-<version>.tar.gz <rpmname>-<version>
           

5. Create new spec file that requires all the packages in that directory under /tmp/OFED_topdir/SPECS/<rpmname>.spec

6. Build the RPM metapackage from the spec file that was created before. As a result, the RPMs will be created under /tmp/OFED_topdir/RPMS/<arch>/

   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.

   Warning

   Installing MLNX_OFED using the “apt-get” tool does not automatically update the firmware.
   To update the firmware to the version included in MLNX_OFED package, run:
   # apt-get install mlnx-fw-updater
   OR:
   Update the firmware to the latest version available on NVIDIA's website as described in “Updating Firmware After Installation” section.

As of MLNX_OFED v4.5, NEO-Host users can opt to install the NEO-Host package embedded in MLNX_OFED package.

In order to install NEO-Host, add the --with-neohost-backend flag to the mlnxofedinstall script run.

Example:

            

            
# /mnt/mlnxofedinstall --with-neohost-backend
