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
WarningIf 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.
WarningPre-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.
WarningOn 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.
WarningIf 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.
WarningOn 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.

All Mellanox, OEM, OFED, or Distribution IB packages will be removed. Do you want tocontinue?[y/N]:y See log file /tmp/mlnx_ofed_iso.21642.log Building OFED RPMs. Please wait... Removing OFED RPMs... Created /tmp/MLNX_OFED_LINUX-x.x-x-rhel7.3-x86_64-ext.tgzThe 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

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”.
(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.WarningInstalling 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.logsDriver 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:
Add the following lines to the "/etc/modprobe.d/mlnx.conf" file.
blacklist mlx5_core blacklist mlx5_ib
Set “ONBOOT=no” in the "/etc/infiniband/openib.conf" file.
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.
