Step 1: Download the Voltaire Drivers that is fitting to your OS and version.

Do find the link for Voltaire QDR Drivers at Download Voltaire OFED Drivers for CentOS

Step 2: Unzip and Untar the Voltaire OFED Package

# bunzip2 VoltaireOFED-1.5_3-k2.6.18-164.el5-x86_64.tar.bz
# tar -xvf VoltaireOFED-1.5_3-k2.6.18-164.el5-x86_64.tar

Step 3: Install the Voltaire OFED Package

# cd VoltaireOFED-1.5_3-k2.6.18-164.el5-x86_64
# ./install

Step 3a: Reboot the Server

Step 4: Setup ip-over-ib

# vim /etc/sysconfig/network-scripts/ifcfg-ib0

# Voltaire Infiniband IPoIB
DEVICE=ib0
ONBOOT=yes
BOOTPROTO=static
IPADDR=10.10.10.1
NETWORK=10.10.10.0
NETMASK=255.255.255.0
BROADCAST=10.10.255.255
MTU=65520

# service openibd start

Step 5 (Optional): Disable yum repository.

If you plan to use yum to local install the opensmd from the Voltaire package directory, you can opt for disabling the yum.

# vim /etc/yum.conf

Type the following at /etc/yum.conf

enabled=0

Step 6: Install Subnet Manager (opensmd). This can be found under

# cd  $VoltaireRootDirectory/VoltaireOFED-1.5_3-k2.6.18-164.el5-x86_64/x86_64/2.6.18-164.15.1.el5

Yum install the opensmd packages

# yum localinstall opensm* --nogpgcheck

Restart the opensmd service

# service opensmd start

Step 7: Check that the Infiniband is working

# ibstat

 You should get “State: Active”

CA 'mlx4_0'
        CA type: MT26428
        Number of ports: 1
        Firmware version: 2.6.0
        Hardware version: a0
        Node GUID: 0x0008f1476328oaf0
        System image GUID: 0x0008fd6478a5af3
        Port 1:
                State: Active
                Physical state: LinkUp
                Rate: 40
                Base lid: 2
                LMC: 0
                SM lid: 14
                Capability mask: 0x0251086a
                Port GUID: 0x0008f103467a5af1

Step 8: Test Connectivity

At the Server side,

# ibping -S

Do Step 1 to 7 again for the Client. Once done,

# ibping -G 0x0008f103467a5af1 (PORT GUID)

You should see a response like this.
