Planning for Open Fabrics enterprise Distribution (OFED)
A configuration file must exist in the /etc/libibverbs.d/ directory
for every Remote Direct Memory Access (RDMA) adapter that is installed
on the system.
The configuration file enables the libibverbs library
to use the driver for the RDMA devices. For example, to use a Mellanox
ConnectX-2 RoCE adapter, the
mx2.driver file
must exist in the /etc/libibverbs.d/ directory. The mx2.driver file
must contain the following code:# cat /etc/libibverbs.d/mx2.driver
driver mx2/etc/libibverbs.d/ directory,
use the IBV_CONFIG_DIR environment variable. To establish
communication between the two nodes, the adapters must have IPv4 or
IPv6 addresses configured.
