IB Bonding
To restart the IPoIB driver, use the following command:
/etc/init.d/openibd restart
Configuring IPoIB
QLogic recommends using the QLogic IFS Installer TUI to configure the IPoIB
driver. Refer to the QLogic Fabric Software Installation Guide for more
information. For using the command line to configure the IPoIB driver use the
following commands.
Editing the IPoIB Configuration File
1. For each IP Link Layer interface, create an interface configuration file,
/etc/sysconfig/network-scripts/ifcfg-NAME, where NAME is the
value of the NAME field specified in the CREATE block. The following is a
sample: /etc/sysconfig/network-scripts/ifcfg-ib1 file:
DEVICE=ib1
BOOTPROTO=static
BROADCAST=192.168.18.255
IPADDR=192.168.18.120
NETMASK=255.255.255.0
ONBOOT=yes
NOTE:
For IPoIB, the INSTALL script for the adapter now helps the user
create the ifcfg files.
IB Bonding
2. After modifying the /etc/sysconfig/ipoib.cfg file, restart the IPoIB driver
with the following:
/etc/init.d/openibd restart
IB bonding is a high availability solution for IPoIB interfaces. It is based on the
Linux Ethernet Bonding Driver and was adopted to work with IPoIB. The support
for IPoIB interfaces is only for the active-backup mode, other modes should not be
used. QLogic only supports bonding across Host Channel Adapter ports at this
time. Bonding port 1 and port 2 on the same Host Channel Adapter is not
supported in this release.
