Installing Mellanox OFED
4.1.3.1
Installation Script
The installation script, mlnxofedinstall, performs the following:
Discovers the currently installed kernel
•
Uninstalls any software stacks that are part of the standard operating system
distribution or another vendor's commercial stack
•
Installs the MLNX_OFED_LINUX binary RPMs (if they are available for the
current kernel)
•
Identifies the currently installed InfiniBand and Ethernet network adapters and
automatically upgrades the firmware.
Note:
The firmware will not be updated if you run the install script with the ‘
--without-
fw-u
pdate’ option.
Note: If you wish to perform a firmware upgrade using customized FW binaries, you
can provide a path to the folder that contains the FW binary files, by running --fw-
image-dir. Using this option, the FW version embedded in the MLNX_OFED package
will be ignored. Example:
./mlnxofedinstall --fw-image-dir /tmp/my_fw_bin_files
Usage
./mnt/mlnxofedinstall [OPTIONS]
Pre-
existing configuration files will be saved with the extension “.conf.rpmsave”.
The installation script removes all previously installed Mellanox OFED packages and
re-installs from scratch. You will be prompted to acknowledge the deletion of the old
packages.
•
If you need to install Mellanox OFED on an entire (homogeneous) cluster, a
common strategy is to mount the ISO image on one of the cluster nodes and
then copy it to a shared file system such as NFS. To install on all the cluster
nodes, use cluster-aware tools (such as pdsh).
•
If your kernel version does not match with any of the offered pre-built RPMs,
you can add yo
ur kernel version by using the “mlnx_add_kernel_support.sh”
script located inside the MLNX_OFED package.
