libmthca1 libmthca1-dbg libmthca-dev libopensm2 opensm 

Load the kernel Modules

Load the proper linux modules. Edit the file /etc/modules and add the following lines

File: /etc/modules

            #tarjeta Mellanox MT26438
            mlx4_ib

            #IP over IB
            ib_ipoib

            # Protocol modules
            # Common modules
            rdma_ucm
            ib_umad
            ib_uverbs

Then, execute the following commands

            modprobe mlx4_ib
            modprobe ib_ipoib
            modprobe rdma_ucm
            modprobe ib_umad
            modprobe ib_uverbs
             

Subnetting Daemon Configuration

Then, edit the file /etc/default/opensm

And change the following line

PORTS=ALL

Like this

PORTS="0x78e7d10300244e95"

Start The Subnetting Service

Start the opensm service

 /etc/init.d/opensm start 

Configure the Infiniband Interface

Edit the file /etc/network/interfaces and add the following lines

File: /etc/network/interfaces

            auto ib0
            iface ib0 inet static
            address 192.168.38.71
            netmask 255.255.255.0
            broadcast 192.168.38.255

Then, start the interface

 ifup ib0 

Test the interface using the following commands

            ibstat
            ibhosts
