why does hpux use card X instead of card Y for nfs?

[Steve Post]

I have two computers with 2 lan cards
BoxA
lan1-hostA1
lan2-hostA2
BoxB
lan1-hostB1
lan2-hostB2

I have a filesytem on boxA called /dirA.
I want to nfs boxA:/dirA to boxB:/nfs_dirA.

I run from BoxB " mount -F nfs boxA:/dirA /nfs_dirA"
BoxA sees an NFS request from BoxB.

Question: 1. Why does BoxB use lan2 (hostB2) for the nfs mount?

PS: I know about subnets. Assume all 4 lan cards are on the same subnet and I'm not changing that. Not going there.

I had a earlier question on this. But my last question had too many pieces. It was not answering THIS part. So, here is ONE question.

I hope this makes it easier.

The way I understand having more than 1 lan card on the same subnet is that you take what you get...

Is it possible to go to boxA and edit /etc/hosts to say boxB lan2(hostB1) and force the nfs mount that way?

now now now.....
This happened on the last question. It went off the deep end. I have one question. No side trips. No solutions. Just an answer to a question.

My question remains:
Why does BoxB use lan2 (hostB2) for the nfs mount?

Because you have both NICs on the same subnet. Since both NICs are on the same subnet the traffic will go out either one. As far as I know, with this setup, there isn't a way to force it to use one NIC over the other.

Thanks.

Steve, sorry about that. Just read:

"The way I understand having more than 1 lan card on the same subnet is that you take what you get..."

N/A for this.

As a lazy guy, I place in the DNS an entry for BOZO

161.184.78.15 BOZO_78 BOZO
161.184.78.16 BOZO_78_16 BOZO

when I mount it for NFS I use the BOZO_78. I also export it to CLOWN_54 in the similar manner.
