Use the ibv_devinfo command to verify that the ports are active.

Procedure

To view the port status of your hardware, run the ibv_devinfo command and look for the following output: Note:

• In the following output, the port_lid return refers to the local identifier (LID) of that port. This LID is unique within the InfiniBand subnet.
• The port: 1 return refers to the first physical port on the adapter.
