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
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".
