G–ULP Troubleshooting<br />
Troubleshooting VirtualNIC and VIO Hardware Issues<br />
Another reason why the host might not be able to see the necessary IOCs is that<br />
the subnet manager has gone down. Issue an iba_saquery command to make<br />
certain that the response shows all of the nodes in the fabric. If an error is<br />
returned and the adapter is physically connected to the fabric, then the subnet<br />
manager has gone down, and this situation needs to be corrected.<br />
Checking the interface definitions on the host<br />
If it is not possible to ping from an InfiniBand host to the Ethernet host, and the<br />
ViPort State of the interface is VIPORT_CONNECTED, then issue an<br />
ifconfig command. The interfaces defined in the configuration files listed in<br />
/etc/sysconfig/network directory for SLES hosts or the<br />
/etc/sysconfig/network-scripts for Red Hat hosts should be displayed in<br />
the list of interfaces in the ifconfig output. For example, the ifconfig file<br />
should show an interface for each EIOC configuration file in the following list:<br />
# ls /etc/sysconfig/network-scripts<br />
ifcfg-eioc1<br />
ifcfg-eioc2<br />
ifcfg-eioc3<br />
ifcfg-eioc4<br />
ifcfg-eioc5<br />
ifcfg-eioc6<br />
Interface does not show up in output of 'ifconfig'<br />
If an interface is not displayed in the output of an ifconfig command, there is<br />
most likely a problem in the definition of that interface in the<br />
/etc/sysconfig/network-scripts/ifcfg- (for RedHat systems)<br />
or /etc/sysconfig/network/ifcfg- (for SuSE systems) file, where<br />
is the name of the virtual interface (e.g., eioc1).<br />
NOTE:<br />
For the remainder of this section, ifcfg directory refers to<br />
/etc/sysconfig/network-scripts/ on RedHat systems, and<br />
/etc/sysconfig/network on SuSE systems.<br />
Issue an ifup command. If the interface is displayed when issuing an<br />
ifconfig command, there may be a problem with the way the interface startup<br />
is defined in the ifcfg directory'/ifcfg- file that is preventing the<br />
interface from coming up automatically.<br />
If the interface does not come up, check the interface definitions in the ifcfg<br />
directory. Make certain that there are no misspellings in the ifcfg- file.<br />
