Verify the Installation (Oracle Linux)

1. Install the adapter in the chassis.

   See Install the Adapter.

2. Power on the server and cable it to an operational InfiniBand switch.

   Refer to the documentation for your server.

   ---

   Note - The InfiniBand switch automatically recognizes the adapter when it is connected to the fabric, if the IB Subnet Manager is running on the switch or on a host within the subnet.

   ---

3. Ensure that the cables are connected to the adapter and switches.
4. Verify that the IB Subnet Manager is running on the switch or a host within the subnet.

   Refer to the documentation for the IB Subnet Manager for more information.

5. Check that the green LED is illuminated 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 switch.

6. Check that the yellow LED is illuminated for each port that is connected to the switch.
7. Verify that the IB-HCA ports are up and the driver is attached:

   The output shows system diagnostic messages that have the string mlx4 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.
