After the installer completes, information about the Mellanox OFED installation such as prefix,
kernel version, and installation parameters can be retrieved by running the command
/etc/
infiniband/info
.
Most of the Mellanox 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.

.

Firmware
• The firmware of existing network adapter devices will be updated if the following two
conditions are fulfilled:
• The installation script is run in default mode; that is, without the option ‘--without-
fw-update’
• The firmware version of the adapter device is older than the firmware version
included with the Mellanox OFED ISO image
Note:
If an adapter’s Flash was originally programmed with an Expansion ROM
image, the automatic firmware update will also burn an Expansion ROM image.
• In case your machine has an unsupported network adapter device, no firmware update
will occur and the error message below will be printed.
