Displaying the Device Manager will show the Mellanox adapter devices and an IPoIB (network)
device for each port. Note that MLNX_VPI configures the ports of VPI cards – at installation time
– to run the InfiniBand protocol. See Chapter 8: “Port Protocol Configuration” for instructions to
change this configuration.
Figure 10: Device Manager
Note:
If the cards are connected to a managed switch, there is no need to run openSM. Only
one OpenSM should run per subnet.
In InfiniBand interfaces, OpenSM is installed as a disabled Windows service. To enable it, enter at
the command line:
> sc start opensm
Whereas in Ethernet interfaces, there is no need to run OpenSM.

Port Type Management Via Driver SW
4.2.1 Linux
If you wish to change the port type, use the connectx_port_config script after the driver is loaded.
The script is installed as part of the Mellanox OFED for Linux package (under /sbin). See the Mel-
lanox OFED for the Linux User Manual available at
http://www.mellanox.com
=> Support =>
InfiniBand Products => Mellanox OFED. Running "/sbin/connectx_port_config -s" will show the
current port configuration for all ConnectX®-2 adapter cards.
Port configuration is saved in the file: /etc/infiniband/connectx.conf. This saved configuration is
restored at driver restart only if done via "/etc/init.d/openibd restart".
Possible port types are:
