Chapter 4. Configuring InfiniBand with QLogic bridges 49

2. Open the IPoIB config file /etc/sysconfig/ipoib.cfg in a text editor.

3. Uncomment the lines in the ipoib.cfg file as shown in Figure 4-15 (at the bottom) and

update the information based on your desired configuration.

Figure 4-15 The ipoib.cfg file

PORTGUID is the GUID of the HCA port that you want to use for this interface.

4. Create an interface profile by creating a file with the name ifcfg-ibX where X is the IPoIB

interface number that you want to use. The easiest way to do create this file is to copy and

modify and existing interface profile for eth0 or eth1.

For this setup, we used the settings (config file) shown in Figure 4-16.

5. Restart IPoIB using the command iba_ipoib restart so that the new IPoIB configuration

settings (ipoib.cfg) are applied. See Figure 4-17.

Figure 4-17 Restart IPoIB driver

Tip: If no information is returned on the port, verify that the system can see the HCA by

running the lspci command. Also, check to verify that the HCA driver is loaded using

the lsmod command. See 4.1.5, “Hints and tips” on page 60 for more details.
