openibd Script
As of MLNX_OFED v2.2-1.0.0 the openibd script supports pre/post start/stop scripts:
This can be controlled by setting the variables below in the /etc/infiniband/openibd.conf file.
OPENIBD_PRE_START
OPENIBD_POST_START
OPENIBD_PRE_STOP
OPENIBD_POST_STOP
Example:
OPENIBD_POST_START=/sbin/openibd_post_start.sh

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.
Driver Load Upon System Boot
Upon system boot, the NVIDIA drivers will be loaded automatically.
To prevent automatic load of the NVIDIA drivers upon system boot:
1. Add the following lines to the "/etc/modprobe.d/mlnx.conf" file.
blacklist mlx4_core
blacklist mlx4_en
blacklist mlx5_core
blacklist mlx5_ib
2. Set "ONBOOT=no" in the "/etc/infiniband/openib.conf" file.
3. 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.
