IB Driver Preparation and Installation

xCAT provides sample postscripts to help you install the Mellanox OpenFabrics Enterprise Distribution (OFED) Infiniband Driver. These scripts are located in opt/xcat/share/xcat/ib/scripts/Mellanox/. You can use these scripts directly or change them to satisfy your own environment. xCAT 2.11 drops support of mlnxofed_ib_install and recommends using version 2 of the script: mlnxofed_ib_install.v2.
