[gpfsug-discuss] Dual server NSDs - change of hostname

[Simon Thompson (IT Research Support)]

Yeah that was my thoughts too given Bob said you can update the server list for an NSD device in 5.0. I also thought that bringing up a second nic and changing the name etc could bring a whole world or danger from having split routing and rp_filter (been there, had the weirdness, RDMA traffic continues but admin traffic randomly fails, but hey, if you like the world crashing down around you….)

To my mind this is simpler:  IF you can mmdelnode without too much suffering, do that. Then reconfigure the host name and whatever else you'd like to do. Then mmaddnode...
