IB Driver Preparation and Installation
|
||||
======================================
|
||||
|
||||
xCAT provides sample postscripts to help you install the Mellanox OpenFabrics Enterprise Distribution (OFED) InfiniBand Driver. These scripts are located in ``opt/xcat/share/xcat/ib/scripts/Mellanox/``. You can use these scripts directly or change them to satisfy your own environment. **xCAT 2.11 drops support of mlnxofed_ib_install and recommends using version 2 of the script: mlnxofed_ib_install.v2**.

Configuration for Diskful Installation
|
||||
======================================
|
||||
|
||||
1. Set script ``mlnxofed_ib_install`` as postbootscript ::
|
||||
|
||||
chdef <node> -p postbootscripts=mlnxofed_ib_install
|
||||
|
||||
2. Specify dependence package **[required for RHEL and SLES]**
|
||||
|
||||
a) Copy the pkglist to the custom directory ::
|
||||
|
||||
cp /opt/xcat/share/xcat/install/<ostype>/compute.<osver>.<arch>.pkglist \
|
||||
/install/custom/install/<ostype>/compute.<osver>.<arch>.pkglist
|
||||
|
||||
b) Edit your /install/custom/install/<ostype>/compute.<osver>.<arch>.pkglist and add one line::
|
||||
|
||||
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/<ostype>/ib.<osver>.<arch>.pkglist#
|
||||
|
||||
c) Make the related osimage use the customized pkglist ::
|
||||
|
||||
chdef -t osimage -o <osver>-<arch>-install-compute \
|
||||
pkglist=/install/custom/install/<ostype>/compute.<osver>.<arch>.pkglist
|
||||
|
||||
Take RHEL 6.4 on x86_64 for example ::
|
||||
|
||||
cp /opt/xcat/share/xcat/install/rh/compute.rhels6.x86_64.pkglist \
|
||||
/install/custom/install/rh/compute.rhels6.x86_64.pkglist
|
||||
|
||||
Edit the ``/install/custom/install/rh/compute.rhels6.x86_64.pkglist`` and add below line
|
||||
``#INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels6.x86_64.pkglist#``
|
||||
|
||||
Then ``/install/custom/install/rh/compute.rhels6.x86_64.pkglist`` looks like below ::

|
||||
pkglist=/install/custom/install/rh/compute.rhels6.x86_64.pkglist
|
||||
|
||||
3. Install node ::
|
||||
|
||||
nodeset <node> osimage=<osver>-<arch>-install-compute
|
||||
rsetboot <node> net
|

Configuration for Diskless Installation
|
||||
=======================================
|
||||
|
||||
1. Specify dependence package **[required for RHEL and SLES]**
|
||||
|
||||
a) Copy a correct pkglist file **shipped by xCAT** according your environment to the ``/install/custom/netboot/<ostype>/`` directory ::
|
||||
|
||||
cp /opt/xcat/share/xcat/netboot/<ostype>/compute.<osver>.<arch>.pkglist \
|
||||
/install/custom/netboot/<ostype>/compute.<osver>.<arch>.pkglist
|
||||
|
||||
b) Edit your ``/install/custom/netboot/<ostype>/<profile>.pkglist`` and add one line ``#INCLUDE:/opt/xcat/share/xcat/ib/netboot/<ostype>/ib.<osver>.<arch>.pkglist#``
|
||||
|
||||
Take RHEL 6.4 on x86_64 for example ::
|
||||
|
||||
cp /opt/xcat/share/xcat/netboot/rh/compute.rhels6.x86_64.pkglist \
|
||||
/install/custom/netboot/rh/compute.rhels6.x86_64.pkglist
|
||||
|
||||
Edit the ``/install/custom/netboot/rh/compute.rhels6.x86_64.pkglist`` and add below line
|
||||
``#INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels6.x86_64.pkglist#``
|
||||
|
||||
Then ``/install/custom/netboot/rh/compute.rhels6.x86_64.pkglist`` looks like below ::

|
||||
nfs-utils
|
||||
openssl
|
||||
dhclient
|
||||
.....
|
||||
|
||||
|
||||
2. Prepare postinstall scripts
|
||||
|
||||
a) Specify postinstall script **shipped by xCAT** ::
|
||||
|
||||
mkdir -p /install/custom/netboot/<ostype>/
|
||||
|
||||
cp /opt/xcat/share/xcat/netboot/<ostype>/<profile>.postinstall \
|
||||
/install/custom/netboot/<ostype>/
|
||||
|
||||
chmod +x /install/custom/netboot/<ostype>/<profile>.postinstall
|
||||
|
||||
Take RHEL 6.4 on x86_64 for example ::
|
||||
|
||||
mkdir -p /install/custom/netboot/rh/
|
||||
cp /opt/xcat/share/xcat/netboot/rh/compute.rhels6.x86_64.postinstall \
|
||||
/install/custom/netboot/rh/
|
||||
chmod +x /install/custom/netboot/rh/compute.rhels6.x86_64.postinstall
|
||||
|
||||
b) Edit ``/install/custom/netboot/<ostype>/<profile>.postinstall`` and add below line in the end: ::
|
||||
|
||||
installroot=$1 ofeddir=/install/post/otherpkgs/<osver>/<arch>/ofed/ \
|
||||
NODESETSTATE=genimage mlnxofed_options=--force /install/postscripts/mlnxofed_ib_install
|
||||
|
||||
|
||||
3. Set the related osimage use the customized pkglist and customized compute.postinsall
|
||||
|
||||
* [RHEL/SLES] ::
|
||||
|
||||
chdef -t osimage -o <osver>-<arch>-netboot-compute \
|
||||
pkglist=/install/custom/netboot/<ostype>/compute.<osver>.<arch>.pkglist \
|
||||
postinstall=/install/custom/netboot/<ostype>/<profile>.postinstall
|
||||
|
||||
* [Ubuntu] ::
|
||||
|
||||
chdef -t osimage -o <osver>-<arch>-netboot-compute \
|
||||
postinstall=/install/custom/netboot/<ostype>/<profile>.postinstall
|
||||
|
||||
4. Generate and package image for diskless installation ::
|
||||
|
||||
genimage <osver>-<arch>-netboot-compute
|
||||
packimage <osver>-<arch>-netboot-compute
|
||||
|
||||
5. Install node ::
|
||||
|
||||
nodeset <nodename> osimage=<osver>-<arch>-netboot-compute
|
||||
rsetboot <nodename> net
|
||||
rpower <nodename> reset

Preparation
|
||||
===========
|
||||
|
||||
Obtain the Mellanox OFED ISO file from `Mellanox official site <http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers>`_ and mount it onto suggested target location on the xCAT MN according your OS and ARCH: ::
|
||||
|
||||
mkdir -p /install/post/otherpkgs/<osver>/<arch>/ofed
|
||||
|
||||
mount -o loop MLNX_OFED_LINUX-<packver1>-<packver2>-<osver>-<arch>.iso \
|
||||
/install/post/otherpkgs/<osver>/<arch>/ofed
|
||||
|
||||
Take sles11 sp1 for x86_64 as an example ::
|
||||
|
||||
mkdir -p /install/post/otherpkgs/sles11.1/x86_64/ofed/
|
||||
|
||||
mount -o loop MLNX_OFED_LINUX-1.5.3-3.0.0-sles11sp1-x86_64.iso \
|
||||
/install/post/otherpkgs/sles11.1/x86_64/ofed/
|
||||
|
||||
|
||||
Take Ubuntu14.4.1 for Power8 LE as an example ::
|
||||
|
||||
mkdir -p /install/post/otherpkgs/ubuntu14.04.1/ppc64el/ofed
|
||||
|
||||
mount -o loop MLNX_OFED_LINUX-2.3-1.0.1-ubuntu14.04-ppc64le.iso \
|
||||
/install/post/otherpkgs/ubuntu14.04.1/ppc64el/ofed
|
||||
|
||||
|
||||
**[NOTE]**
|
||||
|
||||
* Mellanox provides OFED files with **tarball** and **ISO** two format, but for xCAT, we just support **ISO** format right now.
|
||||
|
||||
Copy Sample script **mlnxofed_ib_install** shipped by xCAT into ``/install/postscripts`` before using, such as ::
|
||||
|
||||
cp /opt/xcat/share/xcat/ib/scripts/Mellanox/mlnxofed_ib_install \
|
||||
/install/postscripts/mlnxofed_ib_install
|
||||
|
||||
The **mlnxofed_ib_install** invokes a script ``mlnxofedinstall`` shipped by Mellanox OFED ISO. If you want to pass the argument to ``mlnxofedinstall``, you set the argument to the environment variable ``mlnxofed_options`` which could be read by **mlnxofed_ib_install**. For example: PPE requires the 32-bit version of libibverbs, but the default **mlnxofed_ib_install** will remove all the old ib related packages at first including the 32-bit version of libibverbs. In this case, you can set the environment variable ``mlnxofed_options=--force`` when running the **mlnxofed_ib_install**. For diskful, you should put the environment variable ``mlnxofed_options=--force`` in mypostscript.tmpl. myposcript.tmpl is in ``/opt/xcat/share/xcat/templates/mypostscript/`` by default. When customize it, you should copy it into ``/install/postscripts/myposcript.tmpl`` ::
|
||||
|
||||
mlnxofed_options='--force'
|
||||
export mlnxofed_options

Mellanox OFED Installation Script
|
||||
=================================
|
||||
|
||||
Mellanox provides a tested and packaged version of the OpenFabrics Enterprise Distribution (OFED) driver, named Mellanox OFED (MLNX_OFED). To assist with the installation of the MLNX_OFED driver, xCAT provids a sample postscript: ``mlnxofed_ib_install.v2``.

Configuration for Diskful Installation
|
||||
=======================================
|
||||
|
||||
1. Set script ``mlnxofed_ib_install`` as ``postbootscripts`` or ``postscripts`` ::
|
||||
|
||||
chdef <node> -p postbootscripts="mlnxofed_ib_install -p /install/<subpath>/<MLNX_OFED_LINUX.iso>"
|
||||
|
||||
Or ::
|
||||
|
||||
chdef <node> -p postscripts="mlnxofed_ib_install -p /install/<subpath>/<MLNX_OFED_LINUX.iso>"
|
||||
|
||||
xCAT simulates completely the way Mellanox scripts work by using ``postbootscripts``. This way need to reboot after drive installation to make Mellanox drivers work reliably just like Mellanox suggested. If you want to use the reboot after operating system installation to avoid reboot twice, you can using ``postscripts`` attribute to install Mellanox drivers. This way has been verified in limited scenarios. For more information please refer to :doc:`The Scenarios Have Been Verified </advanced/networks/infiniband/mlnxofed_ib_verified_scenario_matrix>`. You can try this way in other else scenarios if you needed.
|
||||
|
||||
2. Specify dependency package
|
||||
|
||||
Some dependencies need to be installed before running Mellanox scripts. These dependencies are different between different scenario. xCAT configurates these dependency packages by using ``pkglist`` attribute of ``osimage`` definition. Please refer to :doc:`Add Additional Software Packages </guides/admin-guides/manage_clusters/ppc64le/diskful/customize_image/additional_pkg>` for more information::
|
||||
|
||||
# lsdef -t osimage <os>-<arch>-install-compute
|
||||
Object name: <os>-<arch>-install-compute
|
||||
imagetype=linux
|
||||
....
|
||||
pkgdir=/<os packages directory>
|
||||
pkglist=/<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
....
|
||||
|
||||
You can append the ib dependency packages list in the end of ``/<os packages list directory>/compute.<os>.<arch>.pkglist`` directly like below: ::
|
||||
|
||||
#cat /<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
@base
|
||||
@x11
|
||||
openssl
|
||||
ntp
|
||||
rsyn
|
||||
#ib part
|
||||
createrepo
|
||||
kernel-devel
|
||||
kernel-source
|
||||
....
|
||||
|
||||
|
||||
Or if you want to isolate InfiniBand dependency packages list into a separate file, after you edit this file, you can append the file in ``/<os packages list directory>/compute.<os>.<arch>.pkglist`` like below way: ::
|
||||
|
||||
#cat /<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
@base
|
||||
@x11
|
||||
openssl
|
||||
ntp
|
||||
rsyn
|
||||
#INCLUDE:/<ib pkglist path>/<you ib pkglist file>#
|
||||
|
||||
xCAT has shipped some ib pkglist files under ``/opt/xcat/share/xcat/ib/netboot/<ostype>/``, these pkglist files have been verified in sepecific scenario. Please refer to :doc:`The Scenarios Have Been Verified </advanced/networks/infiniband/mlnxofed_ib_verified_scenario_matrix>` to judge if you can use it directly in your environment. If so, you can use it like below: ::
|
||||
|
||||
#cat /<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
@base
|
||||
@x11
|
||||
openssl
|
||||
ntp
|
||||
rsyn
|
||||
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/<ostype>/ib.<os>.<arch>.pkglist#
|
||||
|
||||
Take rhels7.2 on ppc64le for example: ::
|
||||
|
||||
# lsdef -t osimage rhels7.2-ppc64le-install-compute
|
||||
Object name: rhels7.2-ppc64le-install-compute
|
||||
imagetype=linux
|
||||
osarch=ppc64le
|
||||
osdistroname=rhels7.2-ppc64le
|
||||
osname=Linux
|
||||
osvers=rhels7.2
|
||||
otherpkgdir=/install/post/otherpkgs/rhels7.2/ppc64le
|
||||
pkgdir=/install/rhels7.2/ppc64le
|
||||
pkglist=/install/custom/install/rh/compute.rhels7.ib.pkglist
|
||||
profile=compute
|
||||
provmethod=install
|
||||
template=/opt/xcat/share/xcat/install/rh/compute.rhels7.tmpl
|
||||
|
||||
|
||||
**[Note]**: If the osimage definition was generated by xCAT command ``copycds``, default value ``/opt/xcat/share/xcat/install/rh/compute.rhels7.pkglist`` was assigned to ``pkglist`` attribute. ``/opt/xcat/share/xcat/install/rh/compute.rhels7.pkglist`` is the sample pkglist shipped by xCAT, recommend to make a copy of this sample and using the copy in real environment. In the above example, ``/install/custom/install/rh/compute.rhels7.ib.pkglist`` is a copy of ``/opt/xcat/share/xcat/install/rh/compute.rhels7.pkglist``. ::
|
||||
|
||||
# cat /install/custom/install/rh/compute.rhels7.ib.pkglist
|
||||
#Please make sure there is a space between @ and group name
|
||||
wget
|
||||
ntp
|
||||

|
||||
net-snmp
|
||||
rsync
|
||||

|
||||

|
||||

|
||||
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels7.ppc64le.pkglist#
|
||||
|
||||
|
||||
|
||||
3. Install node ::
|
||||
|
||||
nodeset <node> osimage=<osver>-<arch>-install-compute
|
||||
rsetboot <node> net
|
||||
rpower <node> reset
|
||||
|
||||
|
||||
After steps above, you can login target node and find the Mellanox InfiniBand drives are located under ``/lib/modules/<kernel_version>/extra/``.
|
||||
|
||||
Issue ``ibv_devinfo`` command you can get the InfiniBand apater information ::
|
||||

||||
====================
|
||||
|
||||
#. Prepare dependency packages in the pkglist
|
||||
|
||||
In order for the Mellanox installation script to execute successfully, certain dependency packages are required to be installed on the compute node. xCAT provides sample package list files to help resolve these dependencies. The samples are located at ``/opt/xcat/share/xcat/ib/netboot/<os>/``.
|
||||
|
||||
To use the ``/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels7.ppc64le.pkglist``, edit your existing ``pkglist`` file for the target osimage and add the following at the bottom: ::
|
||||
|
||||
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels7.ppc64le.pkglist#
|
||||
|
||||
#. Configure the ``mlnxofed_ib_install`` script to install the MNLX_OFED drivers
|
||||
|
||||
xCAT has a concept of postscripts that can be used to customize the node after the operating system is installed.
|
||||
|
||||
Mellanox recommends that the operating system is rebooted after the drivers are installed, so xCAT recommends using the ``postscripts`` attribute to avoid the need for a second reboot. To invoke the ``mlnxofed_ib_install`` as a postscript ::
|
||||
|
||||
chdef -t node -o <node_name> \
|
||||
-p postscripts="mlnxofed_ib_install -p /install/<path-to>/<MLNX_OFED_LINUX.iso>"
|
||||
|
||||
**[kernel mismatch issue]** The Mellanox OFED ISO is built againt a series of specific kernel version. If the version of the linux kernel does not match any of the Mellanox offered pre-built kernel modules, you can pass the ``--add-kernel-support`` argument to the Mellanox installation script to build the kernel modules based on the version you are using. ::
|
||||
|
||||
chdef -t node -o <node_name> \
|
||||
-p postscripts="mlnxofed_ib_install -p /install/<path-to>/<MLNX_OFED_LINUX.iso> \
|
||||
-m --add-kernel-support -end-"
|
||||
|
||||
#. Provision the node
|
||||
|
||||
#. Verification
|
||||
|
||||
* The Mellanox IB drivers are located at: ``/lib/modules/<kernel_version>/extra/``
|
||||
|
||||
* Use the ``ibv_devinfo`` comamnd to obtain information about the InfiniBand adapter
|
||||
|
||||
* Check the status of ``openibd`` service
|
||||
|
||||
sysVinit: ::

Configuration for Diskless Installation
|
||||
=======================================
|
||||
|
||||
1. Specify dependency package
|
||||
|
||||
Some dependencies need to be installed before running Mellanox scripts. These dependencies are different among different scenarios. xCAT can help user to install these dependency packages by adding these package names to the file specified by the ``pkglist`` attribute of the ``osimage`` definition. Please refer to :doc:`Add Additional Software Packages </guides/admin-guides/manage_clusters/ppc64le/diskful/customize_image/additional_pkg>` for more information::
|
||||
|
||||
# lsdef -t osimage <osver>-<arch>-netboot-compute
|
||||
Object name: <osver>-<arch>-netboot-compute
|
||||
imagetype=linux
|
||||
....
|
||||
pkgdir=/<os packages directory>
|
||||
pkglist=/<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
....
|
||||
|
||||
You can append the ib dependency packages list in the end of ``/<os packages list directory>/compute.<os>.<arch>.pkglist`` directly like below: ::
|
||||
|
||||
#cat /<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
bash
|
||||
nfs-utils
|
||||
openssl
|
||||
dhclient
|
||||
kernel
|
||||
.....
|
||||
|
||||
#ib part
|
||||
createrepo
|
||||
kernel-devel
|
||||
kernel-source
|
||||
....
|
||||
|
||||
|
||||
Or if you want to isolate InfiniBand dependency packages list into a separate file, after you edit this file, you can append the file in ``/<os packages list directory>/compute.<os>.<arch>.pkglist`` like below way: ::
|
||||
|
||||
#cat /<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
bash
|
||||
nfs-utils
|
||||
openssl
|
||||
dhclient
|
||||
kernel
|
||||
.....
|
||||
#INCLUDE:/<ib pkglist path>/<you ib pkglist file>#
|
||||
|
||||
xCAT ships some InfiniBand pkglist files under ``/opt/xcat/share/xcat/ib/netboot/<ostype>/``, these pkglist files have been verified in sepecific scenario. Please refer to :doc:`The Scenarios Have Been Verified </advanced/networks/infiniband/mlnxofed_ib_verified_scenario_matrix>` to judge if you can use it directly in your environment. If so, you can use it like below: ::
|
||||
|
||||
#cat /<os packages list directory>/compute.<os>.<arch>.pkglist
|
||||
bash
|
||||
nfs-utils
|
||||
openssl
|
||||
dhclient
|
||||
kernel
|
||||
.....
|
||||
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/<ostype>/ib.<os>.<arch>.pkglist#
|
||||
|
||||
|
||||
2. Prepare postinstall scripts
|
||||
|
||||
Edit ``postinstall`` script to trigger InfniBand drvices installation during ``genimage``. Using below command to find out where the ``postinstall`` script is defined. ::
|
||||
|
||||
# lsdef -t osimage <os>-<arch>-netboot-compute
|
||||
Object name: <os>-<arch>-netboot-compute
|
||||
....
|
||||
postinstall=/<postinstall script path/compute.<os>.<arch>.postinstall
|
||||
....
|
||||
|
||||
|
||||
|
||||
Edit ``/<postinstall script path/compute.<os>.<arch>.postinstall`` and add below line in the end. ::
|
||||
|
||||
/install/postscripts/mlnxofed_ib_install \
|
||||
-p /install/<path>/<MLNX_OFED_LINUX.iso> -i $1 -n genimage
|
||||
|
||||
|
||||
**[Note]** Mellanox OFED ISO was built against a series of certain kernael versions, If the version of linux kernel you are using does not match with any of the Mellanox offered pre-built kernel modules, you can pass ``--add-kernel-support`` command line argument to Mellanox OFED installation script to build these kernel modules base on the version of linux kernel you are using. The line added into ``<profile>.postinstall`` should like below. ::
|
||||
|
||||
/install/postscripts/mlnxofed_ib_install \
|
||||
-p /install/<subpath>/<MLNX_OFED_LINUX.iso> -m --add-kernel-support -end- -i $1 -n genimage
|
||||
|
||||
|
||||
Take rhels7.2 on ppc64le for example: ::
|
||||
|
||||
#lsdef -t osimage rhels7.2-ppc64le-netboot-compute
|
||||
Object name: rhels7.2-ppc64le-netboot-compute
|
||||
exlist=/opt/xcat/share/xcat/netboot/rh/compute.rhels7.ppc64le.exlist
|
||||
imagetype=linux
|
||||
osarch=ppc64le
|
||||
osdistroname=rhels7.2-ppc64le
|
||||
osname=Linux
|
||||
osvers=rhels7.2
|
||||
otherpkgdir=/install/post/otherpkgs/rhels7.2/ppc64le
|
||||
permission=755
|
||||
pkgdir=/install/rhels7.2/ppc64le
|
||||
pkglist=/install/custom/netboot/rh/compute.rhels7.ppc64le.pkglist
|
||||
postinstall=/install/custom/netboot/rh/compute.rhels7.ppc64le.ib.postinstall
|
||||
profile=compute
|
||||
provmethod=netboot
|
||||
rootimgdir=/install/netboot/rhels7.2/ppc64le/compute
|
||||
|
||||
|
||||
**[Note]**: If the osimage definition was generated by xCAT command ``copycds``, default value ``/opt/xcat/share/xcat/netboot/rh/compute.rhels7.ppc64le.pkglist`` was assigned to ``pkglist`` attribute. ``/opt/xcat/share/xcat/netboot/rh/compute.rhels7.ppc64le.pkglist`` is the sample pkglist shipped by xCAT, recommend to make a copy of this sample and using the copy in real environment. In the above example, ``/install/custom/netboot/rh/compute.rhels7.ppc64le.pkglist`` is a copy of ``/opt/xcat/share/xcat/netboot/rh/compute.rhels7.ppc64le.pkglist``. For the same reason, ``/install/custom/netboot/rh/compute.rhels7.ppc64le.ib.postinstall`` is a copy of ``/opt/xcat/share/xcat/netboot/rh/compute.rhels7.ppc64le.postinstall``.
|
||||
|
||||
``compute.rhels7.ppc64le.pkglist`` looks like below: ::
|
||||
|
||||
# cat /install/custom/netboot/rh/compute.rhels7.ppc64le.pkglist
|
||||
bash
|
||||
nfs-utils
|
||||
openssl
|
||||
dhclient
|
||||
bc
|
||||
......
|
||||
lsvpd
|
||||
irqbalance
|
||||
procps-ng
|
||||
parted
|
||||
net-tools
|
||||
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels7.ppc64le.pkglist#
|
||||
|
||||
``compute.rhels7.ppc64le.ib.postinstall`` looks like below: ::
|
||||
|
||||
# cat /install/custom/netboot/rh/compute.rhels7.ppc64le.ib.postinstall
|
||||
#!/bin/sh
|
||||
#-- Do not remove following line if you want to make use of CVS version tracking
|
||||
.....
|
||||
# [ -r $workdir/$profile.$ext ] && cat $workdir/$profile.$ext | grep -E '^[[:space:]]*#.*[[:space:]]\$Id' >> $installroot/etc/IMGVERSION
|
||||
#done
|
||||
/install/postscripts/mlnxofed_ib_install -p /install/ofed/MLNX_OFED_LINUX-3.2-2.0.0.0-rhel7.2-ppc64le.iso -i $1 -n genimage
|
||||
|
||||
3. Generate and package image for diskless installation ::
|
||||
|
||||
genimage <osver>-<arch>-netboot-compute
|
||||
packimage <osver>-<arch>-netboot-compute
|
||||
|
||||
4. Install node ::
|
||||
|
||||
nodeset <nodename> osimage=<osver>-<arch>-netboot-compute
|
||||
rsetboot <nodename> net
|
||||
rpower <nodename> reset
|
||||
|
||||
After installation, you can login target ndoe and issue ``ibv_devinfo`` command to verify if your InfiniBand driver works well. if everything is fine, you can get the InfiniBand apater information. ::
|
||||
|
||||

#. Prepare dependency packages in the pkglist
|
||||
|
||||
In order for the Mellanox installation script to execute successfully, certain dependency packages are required to be installed on the compute node. xCAT provides sample package list files to help resolve these dependencies. The samples are located at ``/opt/xcat/share/xcat/ib/netboot/<os>/``.
|
||||
|
||||
To use the ``/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels7.ppc64le.pkglist``, edit your existing ``pkglist`` file for the target osimage and add the following at the bottom: ::
|
||||
|
||||
#INCLUDE:/opt/xcat/share/xcat/ib/netboot/rh/ib.rhels7.ppc64le.pkglist#
|
||||
|
||||
#. Configure the ``mlnxofed_ib_install`` script to install the MNLX_OFED drivers
|
||||
|
||||
Edit the ``postinstall`` script on the osimage to invoke the ``mlnxofed_ib_install`` install script.
|
||||
|
||||
For example, take ``rhels7.2-ppc64le-netboot-compute``:
|
||||
|
||||
#. Find the path to the ``postinstall`` script: ::
|
||||
|
||||
# lsdef -t osimage -o rhels7.2-ppc64le-netboot-compute -i postinstall
|
||||
Object name: rhels7.2-ppc64le-netboot-compute
|
||||
postinstall=/opt/xcat/share/xcat/netboot/rh/compute.rhels7.ppc64le.postinstall
|
||||
|
||||
#. Edit the ``/opt/xcat/share/xcat/netboot/rh/compute.rhels7.ppc64le.postinstall`` and add the following: ::
|
||||
|
||||
/install/postscripts/mlnxofed_ib_install \
|
||||
-p /install/<path-to>/<MLNX_OFED_LINUX.iso> -i $1 -n genimage
|
||||
|
||||
*Note: The $1 is a argument that is passed to the the postinstall script at runtime.*
|
||||
|
||||
**[kernel mismatch issue]** The Mellanox OFED ISO is built againt a series of specific kernel version. If the version of the linux kernel does not match any of the Mellanox offered pre-built kernel modules, you can pass the ``--add-kernel-support`` argument to the Mellanox installation script to build the kernel modules based on the version you are using. ::

-p /install/<path-to>/<MLNX_OFED_LINUX.iso> -m --add-kernel-support -end- \
|
||||
-i $1 -n genimage
|
||||
|
||||
#. Generate the diskless image
|
||||
|
||||
Use the ``genimage`` command to generate the diskless image from the osimage definition ::
|
||||
|
||||
genimage <osimage>
|
||||
|
||||
Use the ``packimage`` command to pack the diskless image for deployment ::
|
||||
|
||||
packimage <osimage>
|
||||
|
||||
#. Provision the node
|
||||
|
||||
#. Verification
|
||||
|
||||
* The Mellanox IB drivers are located at: ``/lib/modules/<kernel_version>/extra/``
|
||||
|
||||
* Use the ``ibv_devinfo`` comamnd to obtain information about the InfiniBand adapter
|

Preparation
|
||||
===========
|
||||
|
||||
Obtain the Mellanox OFED ISO
|
||||
----------------------------
|
||||
|
||||
Obtain the Mellanox OFED ISO file from `Mellanox official Download Page <http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers>`_ and put it into one place under ``/install`` directory depending on your need.
|
||||
|
||||
**[NOTE]**
|
||||
|
||||
* Mellanox provides OFED drivers in **tarball** and **ISO image** formats. xCAT only supports the **iso** format at this time.
|
||||
* Mellanox provides different OFED ISOs depending on operating system and machine architecture, named like MLNX_OFED_LINUX-<packver1>-<packver2>-<osver>-<arch>.iso, you should download correct one according to your environment.
|
||||
* Mellanox has some updates and known issues for echo OFED, please read `InfiniBand/VPI Software Overview <http://www.mellanox.com/page/software_overview_ib>`_ to understand these information.
|
||||
* The Mellanox links offered above maybe outdate in future for Mellanox updates its web page, xCAT will keep updating for synchronization. If we don't update in time, please access `Mellanox web portal <http://www.mellanox.com>`_ to find ``Support/Education`` then ``InfiniBand/VPI Drivers`` lables.
|
||||
|
||||
Prepare Install Script
|
||||
----------------------
|
||||
|
||||
**mlnxofed_ib_install.v2** is a sample script, its framework can help you install Mellanox drives easily. But in specific scenario, some detail need to be modified to meet requirement, such like dependency package list. It has been verified in limited scenarios and can work as solution in these scenarios. For these scenarions information please refer to :doc:`The Scenarios Have Been Verified </advanced/networks/infiniband/mlnxofed_ib_verified_scenario_matrix>`.
|
||||
|
||||
Copy **mlnxofed_ib_install.v2** into ``/install/postscripts`` and change name to **mlnxofed_ib_install** ::
|
||||
|
||||
cp /opt/xcat/share/xcat/ib/scripts/Mellanox/mlnxofed_ib_install.v2 \
|
||||
/install/postscripts/mlnxofed_ib_install
|
||||
|
||||
chmod +x /install/postscripts/mlnxofed_ib_install
|
||||
|
||||
``mlnxofed_ib_install`` has some options, **'-p' is always needed**.
|
||||
Below are the details of these options:
|
||||
|
||||
* **-p**: [required]--the directory where the OFED iso file is located
|
||||
* **-m**: [optional]--the mlnxofed_ib_install invokes a script ``mlnxofedinstall`` shipped by Mellanox OFED iso. Use this option to pass arguments to the ``mlnxofedinstall``. You must include ``-end-`` at the completion of the options to distinguish the option list. if you don't pass any argument to ``mlnxofedinstall``, **defualt value** ``--without-32bit --without-fw-update --force`` will be passed to ``mlnxofedinstall`` by xCAT.
|
||||
* **-i**: [required for diskless]--the image root path
|
||||
* **-n**: [required for diskless]--nodeset status, the value is 'genimage'
|
||||
|
||||
In general you can use ``mlnxofed_ib_install`` like below ::
|
||||
|
||||
mlnxofed_ib_install -p /install/<path>/<MLNX_OFED_LINUX.iso>
|
||||
|
||||
If need to pass ``--without-32bit --without-fw-update --add-kernel-support --force`` to ``mlnxofedinstall``, refer to below command. ::
|
||||
|
||||
mlnxofed_ib_install -p /install/<path>/<MLNX_OFED_LINUX.iso> \
|
||||
-m --without-32bit --without-fw-update --add-kernel-support --force -end-
|
||||
|
||||
**[Note]** We recommend to update your firmware to the version Mellanox supported in its release notes to avoid unexpected problem when you install InfiniBand driver.

|
||||
Preventing upgrade of the Mellanox Drivers
|
||||
------------------------------------------
|
||||
|
||||
Known Issue 1
|
||||
-------------
|
||||
On RedHat operating systems, after the Mellanox drivers are installed, you may have a requirement to update your operating system to a later version.
|
||||
Some operating systems may ship InfiniBand drivers that are higher version than the Mellanox drivers you have installed and therefor may update the existing drivers.
|
||||
|
||||
To prevent this from happening, add the following in the ``/etc/yum.conf`` ::
|
||||
|
||||
After you install mellanox derives in rhels7.2 successfully by xCAT, maybe you have new requirement to upgrade your operating system to higher version. In this case you probably hit such problem the IB adaptor drives shipped by operating system is higher than the Mellanox drives you have installed. That means the the Mellanox drives will be replaced by the drives shipped by operating system. If it's not the result you expect, you hope keep the Mellanox drives after operating system upgraded, please add below statement into ``/etc/yum.conf`` in your target node after you install mellanox derives successfully for the first time. ::

Known Issue 2
|
||||
-------------
|
||||
Development packages in SLES
|
||||
----------------------------
|
||||
|
||||
If you want to use ``--add-kernel-support`` attribute in sles12.1 and ppc64le scenario, you will find some dependency packages are not shipped by SLES Server DVDs, such like ``python-devel``, it's shipped in SDK DVDs. xCAT doesn't ship specific pkglist to support such scenario. If you have such requirement, please used ``otherpkglist`` and ``otherpkgs`` attributes to prepare dependency packages repository ahead. If you need help about ``otherpkglist`` and ``otherpkgs`` attributes, please refer to :doc:`Add Additional Software Packages </guides/admin-guides/manage_clusters/ppc64le/diskful/customize_image/additional_pkg>`.
|
||||
If using the ``--add-kernel-support`` attribute on SLES operating systems, you may find problems with installing some dependency packages which are not shipped by the SLES server DVDs. The development rpms are provided by the SDK DVDs. Refer to :doc:`Add Additional Software Packages </guides/admin-guides/manage_clusters/ppc64le/diskful/customize_image/additional_pkg>` to configure the SDK repositories.
