Re: Round robin does not work

$

Thanks for the answer.

What's peculiar is that if I go through the client I see round robin with both multipaths and under no circumstance will it switch to the other interface. If I manually set the path selection to fixed I can use either path (though one is half the speed of the other for some reason)

When listing my nmp devices I do not find the C0:T0:L2 and I'm not sure if I'm suppose to either since like I said it works during fixed...

 

I highlighted the two instances where I found the same LUN.
