I have a simple GPFS cluster with IB network. 1 NSD server, 2 clients
Server has 2HCA dual port
Clients have 1HCA dual port
2 IB switches
This is the conf verbs wise:
how does GPFS decide which ports to be used to establish connections between nodes?
For example which port C1 will use to connect to which port of S1?
I am asking because I have found that the order of the ports in the lists is relevant to have RDMA connections properly working
