Installing the IBM Flex System adapter
If you don’t see the mlx4_en driver, run:
’ modprobe mlx4_en’
Another option is to use the command below to see which modules are active.
Example:
The “Usage: openibd {start|stop|restart|status}” command to modify this file and
thereby control the drivers.
Check the network interface name :
run: ifconfig -a
run: ethtool <interface>
> Host# lsmod |grep mlx4_en
mlx4_en 96382 0
mlx4_core 1184104 2 mlx4_en
Edit ”/etc/infiniband/openib.conf” which modules needs to load
from a service.
Load MLX4_EN module
MLX4_EN_LOAD=yes
> ifconfig –a
