anyway.. please be aware, cnfs IP handling is done over aliasing.. so in case you have configured the IP directly on the interface, that won't work

<b>Betreff:</b> [EXTERNAL] [gpfsug-discuss] Seeking cNFS/GPFS advice. Add two IPs to cNFS pool</font>
<div> </div>

<div class="PlainText">Hello, I am relatively new to GPFS/cNFS. I have contacted reps and IBM and DDN (our vendor) w/no concrete answers.<br>
<br>
We have two servers<br>
linux server gpfs0 infiniband IP addr 10.0.136.84<br>
linux server gpfs1 infiniband IP addr 10.0.136.85<br>
<br>
gpfs0 server already has cnfs node name gpfs0-adm<br>
gpfs1 server already has cnfs node name gpfs1-adm<br>
<br>
We want to bind 10.0.136.86, 10.0.136.87 to these nodes to extend the cnfs pool.<br>
Below are the commands I think will work<br>
<br>
mmchnode --cnfs-interface= 10.0.136.86 -N gpfs0-adm <br>
<br>
mmchnode --cnfs-interface= 10.0.136.87 -N gpfs1-adm <br>
<br>
<br>
<br>
Below are some information about the current setup for Ethernet.<br>
