3 Management and Tools Overview

3.1 Network Mangemant and Clustering Software

Download and install on all nodes the Mellanox OpenFabric software package for Linux, Windows, or other
operating systems from the Mellanox software website:
http://www.mellanox.com.> Downloads > InfiniBand SW/Drivers.
This software package provides connectivity for server and storage systems utilizing High Performance
Computing (HPC) or enterprise data center (EDC) applications across an InfiniBand fabric. It also provides
a subnet manager for simple network configuration and network administration and diagnostic tools for net-
work management.
Switches can be either managed or unmanaged.

3.2 Unmanaged Switch Updating Firmware

The switch is delivered with the latest Firmware available at the time of production. New firmware versions
will be posted on the Mellanox firmware download page:
http://www.mellanox.com> Downloads > Firmware.
You will need the Mellanox Firmware Tools package available in the Mellanox OpenFabrics software pack-
age, to update firmware for this switch. It can also be downloaded from:
http://www.mellanox.com.> Downloads > InfiniBand SW/Drivers.
You will also need to download and unzip the firmware binary image. This is provided in the Mellanox Web
site at: http://www.mellanox.com> Downloads > Firmware and go to the InfiniScale IV Switch systems.
Click in the Table for the FW image that you need.

3.2.1 Instructions for Reprogramming Over the InfiniBand Network

To update an MT48436 InfiniScale IVswitch device having a specific GUID (for example,
0x00000006660abcd0) or LID, the following are the recommended steps to update the device firmware.
1. Make sure all subnet ports are in the active state. One way to check this is to run opensm, the Subnet
Manager.
[root@mymach]> /etc/init.d/opensmd start
opensm start
2. Make sure the local ports are active by running 'ibv_devinfo'.
3. Obtain the device LID. There are two ways to do that:
I. Using the "mst ib add" command:
The "mst ib add"runs the ibdiagnet tool to discover the InfiniBand fabric and then lists the discovered IB
nodes as an mst device under /dev/mst/ directory. These devices can be used for access by other MFT
tools.
[root@mymach]> mst ib add
