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
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).
