[lustre-discuss] Can't join an IBM Power9 System AC922 to an existing Lustre Service (Intel Servers) through Mellanox Infiniband

[Americo Ojeda]

I did some communications test with tcpdump, if a use "telnet server_ip
988" a get some response from server, but when use "hctl ping
server_ip at o2ib" I get nothing from tcpdump. I think the problem is with
my infiniband communication.

some recomentation?
