4.1.3 Installing Mellanox OFED

4.1.3.1 Installation Script

The installation script,
• 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 Ethernet network adapters and automatically
the firmware
Note: If you wish to perform a firmware upgrade using customized FW binaries, you can
provide a path to the folder that contains the FW binary files, by running
. Using this option, the FW version embedded in the MLNX_OFED package will be
dir
ignored.
Example:
./mlnxofedinstall --fw-image-dir /tmp/my_fw_bin_files
Usage
./mnt/mlnxofedinstall [OPTIONS]
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).
1. The firmware will not be updated if you run the install script with the '--without-fw-update' option.
