6 OpenSM - Subnet Manager
OpenSM v3.3.11 is an InfiniBand Subnet Manager. For Mellanox WinOF VPI to operate,
OpenSM must be running on at least one host machine in the InfiniBand cluster.
OpenSM can run as a Windows service which can be started manually from the following direc-
tory: <installation_directory>\tools. However, in WinOF 4.3 OpenSM is not defined as a service.
OpenSM as a service will use the first port which is not in "down" state.
To register it as a service run the following
command:
To start OpenSM as a service run:
To run OpenSM manually, enter on the command line:
For additional run options, enter: opensm.exe -h
Notes
For long term running, please avoid using the '-v' (verbosity) option to avoid exceeding
disk quota.
Running OpenSM on multiple servers may lead to incorrect OpenSM behavior.
Please do not run more than a single instance of OpenSM in the subnet.
Please use the embedded OpenSM in the WinOF package for testing purpose and small
cluster. Otherwise, we recommend using OpenSM from FabricIT EFM™ or UFM™.
