It’s not possible I suppose. LNet module read configuration only once during the module load stage. Therefore you cannot reconfigure it without unloading. So, you need to stop Lustre anyway.

Is there a possibility to tell lnet to completely switch to tcp, unload ko2iblnd.ko and next unload the IB stack, load the new IB stack, load a matching ko2iblnd.ko and then switch lnet back to preferring o2ib?
