• 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.
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.
