After installation completion, information about the OFED installation, such as prefix, kernel
version, and installation parameters can be retrieved by running the command /etc/
infiniband/info. Most of the OFED components can be configured or reconfigured after the
installation, by modifying the relevant configuration files. See the relevant chapters in this
manual for details.
The list of the modules that will be loaded automatically upon boot can be found in the /etc/
infiniband/openib.conf file.
