36••••••a path to the folder that contains the FW binary files, by running --fw-image-dir. Using thisoption, the FW version embedded in the MLNX_OFED package will be ignored. Example:./mlnxofedinstall --fw-image-dir /tmp/my_fw_bin_filesUsage./mnt/mlnxofedinstall [OPTIONS]The installation script removes all previously installed Mellanox OFED packages and re-installs fromscratch. 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 isto mount the ISO image on one of the cluster nodes and then copy it to a shared file system suchas 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 yourkernel version by using the “mlnx_add_kernel_support.sh” script located inside theMLNX_OFED package.The “mlnx_add_kernel_support.sh” script can be executed directly from the mlnxofedinstallscript. For further information, please see '--add-kernel-support' option below.ExampleThe following command will create a MLNX_OFED_LINUX ISO image for RedHat 6.3 under the /tmp directory.# ./MLNX_OFED_LINUX-x.x-x-rhel6.3-x86_64/mlnx_add_kernel_support.sh -m /tmp/MLNX_OFED_LINUX-x.x-x-rhel6.3-x86_64/ --make-tgzNote: This program will create MLNX_OFED_LINUX TGZ for rhel6.3 under /tmp directory.All Mellanox, OEM, OFED, or Distribution IB packages will be removed.Do you want to continue?[y/N]:ySee log file /tmp/mlnx_ofed_iso.21642.logBuilding OFED RPMs. Please wait...Removing OFED RPMs...Created /tmp/MLNX_OFED_LINUX-x.x-x-rhel6.3-x86_64-ext.tgzThe script adds the following lines to /etc/security/limits.conf for the userspace componentssuch as MPI:* soft memlock unlimited* hard memlock unlimitedThese settings set the amount of memory that can be pinned by a userspace applicationto unlimited. If desired, tune the value unlimited to a specific amount of RAM.Pre-existing configuration files will be saved with the extension “.conf.rpmsave”.On Redhat and SLES distributions with errata kernel installed there is no need to usethe mlnx_add_kernel_support.sh script. The regular installation can be performed andweak updates mechanism will create symbolic links to the MLNX_OFED kernelmodules.On Ubuntu and Debian distributions drivers installation use Dynamic Kernel ModuleSupport (DKMS) framework. Thus, the drivers' compilation will take place on the hostduring MLNX_OFED installation. Therefore, using "mlnx_add_kernel_support.sh" isirrelevant on Ubuntu and Debian distributions. |
