I am facing an issue while configuring rdma and Infiniband on my two nodes. Both of these two nodes are connected and I have installed the recommended software libraries and packages required.
But my port status is down and physical state is Disabled. I tried to enable the state but I get the error of can’t open MAD PORT
ibwarn:  mad_rpc_open_port: can’t open UMAD port ((null):0)
src/ibnetdisc.c:784; can’t open MAD port ((null):0)
/usr/sbin/ibnetdiscover: iberror: failed: discover failed
I have also tried running commands as sudo but still I face the error. Can you guys guide me of what could be the issue ?
Here is my ib_status output:
Infiniband device ‘mlx5_0’ port 1 status:
