Running "ibv_devinfo" command on H1 would list the 2 adapter names. For ConnectX adapters,
the names would be mlx4_0 and mlx4_1.
Running "mst ib add" would add ib devices from the default port (first active port on the first
adapter) - only Subnet1 nodes would be listed.
To add the nodes of the second subnet, the source adapter and port should be specified to the "mst
ib add" command in the following format:
Example:
1. Add nodes of both subnets, Run:
2. List the devices:
You can use the above device names with the MFT tools.
mst ib add <hca_name> <hca_port>
> mst ib add mlx4_0 1
> mst ib add mlx4_1 2
> mst status
