xCAT simulates completely the way Mellanox scripts work by using ``postbootscripts``. This way need to reboot after drive installation to make Mellanox drives work reliably just like Mellanox suggested. If you want to use the reboot after operating system installation to avoid reboot twice, you can using ``postscripts`` attribute to install Mellanox dreives. This way has been verified in limited scenarios. For more information please refer to :doc:`The Scenarioes Have Been Verified </advanced/networks/infiniband/mlnxofed_ib_verified_scenario_matrix>`. You can try this way in other else scenarios if you needed.
