3.12.1 Configuring Internet Protocol over InfiniBand (IPoIB)

To configure Internet Protocol over InfiniBand (IPoIB):

  1. Edit the /etc/sysconfig/network-scripts/ifcfg-ibN configuration file, where N is the number of the interface. The following example shows the configuration for the interface ib0:

    DEVICE=ib0
    TYPE=InfiniBand
    ONBOOT=yes 
    DHCP_HOSTNAME="myhost.mydom.com"
    BOOTPROTO=static
    IPADDR=192.168.100.1
    NETMASK=255.255.255.0
    IPV4_FAILURE_FATAL=yes
    IPV6INIT=no 
    CONNECTED_MODE=no
    NAME=ib0 
  2. Stop the NetworkManager service:

    # systemctl stop NetworkManager
  3. Start the RDMA service:

    # systemctl start rdma
  4. Bring up the interface:

    # ifup ibN
