Do you set ip address for these adapters? Refer to the description of verbsRdmaCm in ‘Command and Programming Reference':
If RDMA CM is enabled for a node, the node will only be able to establish RDMA connections using RDMA CM to other nodes with verbsRdmaCm enabled. RDMA CM enablement requires IPoIB (IP over InfiniBand) with an active IP address for each port. Although IPv6 must be enabled, the GPFS implementation of RDMA CM does not currently support IPv6 addresses, so an IPv4 address must be used.
