I have an Ubuntu 18.04 server with Mellanox ConnextX-3 Infiniband cards.
I downloaded Mellanox OFED drivers (MLNX_OFED_LINUX-4.5-1.0.1.0-ubuntu18.04-x86_64) and was able to install them and get everything working.
However, I seem to be getting this warning with every command I run (like ibv_devices):
libibverbs: Warning: couldn’t load driver ‘nes’: libnes-rdmav2.so: cannot open shared object file: No such file or directory
libibverbs: Warning: couldn’t load driver ‘vmw_pvrdma’: libvmw_pvrdma-rdmav2.so: cannot open shared object file: No such file or directory
libibverbs: Warning: couldn’t load driver ‘ocrdma’: libocrdma-rdmav2.so: cannot open shared object file: No such file or directory
.

device node GUID
mlx4_1 0002c90300xxxxxx
mlx4_0 0002c90300yyyyyy
It seems to me that these libraries are providing RDMA interfaces for different providers. However, I only have Mellanox NICs on my machine, and don’t need any of these. Is there any way to suppress these warnings, or is this something I should fix for proper operation of my card?
Thanks,
Ankush
