Verify IB Connectivity (Oracle Linux)

Language:

Ensure that the adapter is properly installed in the server.
See Install the Adapter.

Power on the server and cable it to an operational peer IB switch.
Refer to the documentation for your network hardware for more information at http://docs.oracle.com/cd/E36265_01/index.html or http://docs.oracle.com/cd/E36256_01/index.html.

Ensure that the cables are connected to the adapter and IB switches.

Verify that the Subnet Manager is running on the IB switch or a host within the subnet.
Refer to the documentation for your network hardware for more information at http://docs.oracle.com/cd/E36265_01/index.html or http://docs.oracle.com/cd/E36256_01/index.html.

Check that the green LED is lit for each port that is connected to the switch.
If the green LED is not on, check the cable connections at the adapter and the IB switch.

Ensure that the required OS has been installed.
See IB Overview (Oracle Linux).

Verify that the ports are up and the driver is attached.

The output shows system diagnostic messages that have the string sif in the message (the name of the Linux driver). Included in the output is a message that indicates whether the port is up or down.

Note - For accurate IB device information, such as GUID identification in a server with more than one IB device, use the ibstat command.
