[gpfsug-discuss] CNFS and multiple IP addresses

[Buterbaugh, Kevin L]

Hi All,

I’ve looked in the documentation and on the GPFS Wiki for the answer to this question but haven’t found it.  Please feel free to point me to docs / web pages if I’ve missed something.

One of the GPFS clusters I administer uses CNFS, which I did not set up on this cluster … and the person who did is now an employee of another organization.  The cluster in question runs GPFS 4.1.0.x, although I doubt that matters.

There are 4 CNFS servers, each of which has 2 IP addresses listed under the CNFS IP address list when running “mmlscluster —cnfs”.  I want to delete one of those two IP addresses for each server due to a planned network reorganization.  How do I do that?  Or do I need to completely delete the server from CNFS and add it back in with just the one IP address I want to keep?

Thanks in advance…
