An example of OPENIBD_POST_START script for activating all interfaces is provided in the MLNX_OFED
package under the docs/scripts/openibd-post-start-configure-interfaces/ folder.
4.1.3.6
Driver Load Upon System Boot
Upon system boot, the Mellanox drivers will be loaded automatically.
To prevent automatic load of the Mellanox drivers upon system boot:
•
Add the following lines to the "/etc/modprobe.d/mlnx.conf" file.
blacklist mlx4_core
blacklist mlx4_en
blacklist mlx5_core
blacklist mlx5_ib
•
Set “ONBOOT=no” in the "/etc/infiniband/openib.conf" file.
•
If the modules exist in the initramfs file, they can automatically be loaded by the
kernel.
To prevent this behavior, update the initramfs using the operating systems’
standard tools.
Note: The process of updating the initramfs will add the blacklists from step 1, and
will prevent the kernel from loading the modules automatically.
