Here's what I usually do:
nvme connect -t rdma -a 100.0.50.90 -s 1055 -n nvme-subsystem-TEST2 -w <IP of 1st ifc>
nvme connect -t rdma -a 100.0.50.90 -s 1055 -n nvme-subsystem-TEST2 -w <IP of 2nd ifc>

This should give you two paths to nvme-subsystem-TEST2 (repeat for the other
one as well).

Thanks,
