Thanks in advance!

Will anyone give some advice? Thanks in advance. Here are the different
file locations on my SLES and RHEL nodes. 
 
Looks like rdma_ucm module didn't get loaded. Check
/etc/infiniband/openib.conf and make sure loading rdma_ucm is set
properly:
 
[root at cst-53 dapl]# cat /etc/infiniband/openib.conf
# Start HCA driver upon boot
ONBOOT=yes
 
# Load RDMA_CM module
RDMA_CM_LOAD=yes
 
# Load RDMA_UCM module
RDMA_UCM_LOAD=yes
