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 automat-

ically

1

 upgrades the firmware

• The installation script removes all previously installed Mellanox OFED packages and 

re-installs from scratch. You will be prompted to acknowledge the deletion of the old 
packages.

• If you need to install Mellanox 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 (such as pdsh).

• 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 

under the docs/ directory.

Usage:

1. The firmware will not be updated if you run the install script with the ‘--without-fw-update’ option.

Pre-existing configuration files will be saved with the extension “.conf.rpmsave”.

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.
