Step 3.
Use the md5sum utility to confirm the file integrity of your ISO image. Run the following
command and compare the result to the value provided on the download page.
4.1.3 Installing Mellanox OFED
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

upgrades the firmware
Usage
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.
host1$ md5sum MLNX_OFED_LINUX-<ver>-<OS label>.iso
1. The firmware will not be updated if you run the install script with the ‘--without-fw-update’ option.
./mnt/mlnxofedinstall [OPTIONS]
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.
