OpenSM Activation
OpenSM is a service required by managed networks in InfiniBand environments, and must be
activated 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 does not run as a service during installation as it requires the GUID parameter to decide
on which port to work. Setting OpenSM upon setup results in it working only for the first port
and not for the others.
To run OpenSM as a service, assuming the package was installed in the default path, use:
To start the service, run:
