G–ULP Troubleshooting Troubleshooting VirtualNIC and VIO Hardware Issues Verify that the proper VirtualNIC driver is running Check that a VirtualNIC driver is running by issuing an lsmod command on the InfiniBand host. Make sure that the qlgc_vnic is displayed on the list of modules. Following is an example: st186:~ # lsmod Module Size Used by cpufreq_ondemand 25232 1 cpufreq_userspace 23552 0 cpufreq_powersave 18432 0 powernow_k8 30720 2 freq_table 22400 1 powernow_k8 qlgc_srp 93876 0 qlgc_vnic 116300 0# Verifying that the qlgc_vnic.cfg file contains the correct information Use the following scenarios to verify that the qlgc_vnic.cfg file contains a definition for the applicable virtual interface: Issue the command ib_qlgc_vnic_query to get the list of IOCs the host can see. If the list is empty, there may be a syntax error in the qlgc_vnic.cfg file (e.g., a missing semicolon). Look in /var/log/messages at the time qlgc_vnic was last started to see if any error messages were put in the log at that time. If the qlgc_vnic.cfg file has been edited since the last time the VirtualNIC driver was started, the driver needs restarted. To restart the driver, so that it uses the current qlgc_vnic.cfg file, issue a /etc/init.d/qlgc_vnic restart. G-2 D000046-005 B
G–ULP Troubleshooting Troubleshooting VirtualNIC and VIO Hardware Issues Verifying that the host can communicate with the I/O Controllers (IOCs) of the VIO hardware To display the Ethernet VIO cards that the host can see and communicate with, issue the command ib_qlgc_vnic_query. The system returns information similar to the following: IO Unit Info: port LID: 0003 port GID: fe8000000000000000066a0258000001 change ID: 0009 max controllers: 0x03 controller[ 1] GUID: 00066a0130000001 vendor ID: 00066a device ID: 000030 IO class : 2000 ID: Chassis 0x00066A00010003F2, Slot 1, IOC 1 service entries: 2 service[ 0]: 1000066a00000001 / InfiniNIC.InfiniConSys.Control:01 service[ 1]: 1000066a00000101 / InfiniNIC.InfiniConSys.Data:01 controller[ 2] GUID: 00066a0230000001 vendor ID: 00066a device ID: 000030 IO class : 2000 ID: Chassis 0x00066A00010003F2, Slot 1, IOC 2 service entries: 2 service[ 0]: 1000066a00000002 / InfiniNIC.InfiniConSys.Control:02 service[ 1]: 1000066a00000102 / InfiniNIC.InfiniConSys.Data:02 controller[ 3] GUID: 00066a0330000001 vendor ID: 00066a device ID: 000030 IO class : 2000 D000046-005 B G-3
