4.1 OpenSM Activation

OpenSM is a service required by managed networks in InfiniBand environments, and must be acti-vated in one of the machines running on the subnet, otherwise the interface link will not come up. If the cards are connected to a managed network, there is no need to run OpenSM. Only one OpenSM should run per subnet.

In Ethernet interfaces, running OpenSM is not required.

OpenSM is embedded in the MLNX_VPI for Windows package and installed as a disabled Win-dows service.

To enable it, after installing the WinOF package, enter at the command line:

For further information, please refer to the “OpenSM - Subnet Manager” chapter in the User Man-ual.
