2. Create three files that correspond to the names you are assigning the NICS (ifcfg-sio_mgmt, ifcfg-
sio_d_1, and ifcfg-sio_d_2):
cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-
sio_mgmt
cp /etc/sysconfig/network-scripts/ifcfg-sio_mgmt /etc/sysconfig/network-scripts/ifcfg-
sio_d_1
cp /etc/sysconfig/network-scripts/ifcfg-sio_mgmt /etc/sysconfig/network-scripts/ifcfg-
sio_d_2
3. Configure each of the files you created with the correct management or data IP addresses.
a. For the ifcfg-sio_mgmt file, run:
echo DEVICE= sio_mgmt > /etc/sysconfig/network-scripts/ifcfg-sio_mgmt
echo STARTMODE=onboot >> /etc/sysconfig/network-scripts/ifcfg-sio_mgmt
echo USERCONTROL=no >> /etc/sysconfig/network-scripts/ifcfg-sio_mgmt
echo BOOTPROTO=static >> /etc/sysconfig/network-scripts/ifcfg-sio_mgmt
echo NETMASK=X.X.X.X >> /etc/sysconfig/network-scripts/ifcfg-sio_mgmt
echo IPADDR=X.X.X.X >> /etc/sysconfig/network-scripts/ifcfg-sio_mgmt
echo 1 >/sys/bus/pci/rescan
b. For the ifcfg-sio_d_1 file, run:
echo DEVICE= sio_d_2 > /etc/sysconfig/network-scripts/ifcfg-sio_d_1
echo STARTMODE=onboot >> /etc/sysconfig/network-scripts/ifcfg-sio_d_1
echo USERCONTROL=no >> /etc/sysconfig/network-scripts/ifcfg-sio_d_1
echo BOOTPROTO=static >> /etc/sysconfig/network-scripts/ifcfg-sio_d_1
echo NETMASK=X.X.X.X >> /etc/sysconfig/network-scripts/ifcfg-sio_d_1
echo IPADDR=X.X.X.X >> /etc/sysconfig/network-scripts/ifcfg-sio_d_1
echo 1 >/sys/bus/pci/rescan
c. For the ifcfg-sio_d_2 file, run:
echo DEVICE= sio_d_2 > /etc/sysconfig/network-scripts/ifcfg-sio_d_2
echo STARTMODE=onboot >> /etc/sysconfig/network-scripts/ifcfg-sio_d_2
echo USERCONTROL=no >> /etc/sysconfig/network-scripts/ifcfg-sio_d_2
echo BOOTPROTO=static >> /etc/sysconfig/network-scripts/ifcfg-sio_d_2
echo NETMASK=X.X.X.X >> /etc/sysconfig/network-scripts/ifcfg-sio_d_2
echo IPADDR=X.X.X.X >> /etc/sysconfig/network-scripts/ifcfg-sio_d_2
echo 1 >/sys/bus/pci/rescan
4. Configure the gateway:
echo “NETWORKING=yes” >> /etc/sysconfig/network
echo “GATEWAY=XXX.XXX.XXX.XXX” >> /etc/sysconfig/network
where XXX.XXX.XXX.XXX is the gateway IP address.
5. Create the /etc/udev/rules.d/70-persistent-ipoib.rules file:
touch /etc/udev/rules.d/70-persistent-ipoib.rules
