Hi Simon, I will do that before I go to the customer with a separate switch as a last resort :) Thanks Venlig hilsen / Best Regards Andi Rhod Christiansen From: gpfsug-discuss-boun...@spectrumscale.org [mailto:gpfsug-discuss-boun...@spectrumscale.org] On Behalf Of Simon Thompson (IT Research

Yes i think my last resort might be to go to customer with a separate switch and do the reconfiguration. Thanks  -Original Message- From: gpfsug-discuss-boun...@spectrumscale.org [mailto:gpfsug-discuss-boun...@spectrumscale.org] On Behalf Of Jonathan Buzzard Sent: 11. oktober 2017

Hi, Does anyone know how to change the ips on all the nodes within a cluster when gpfs and interfaces are down? Right now the cluster has been shutdown and all ports disconnected(ports has been shut down on new switch) The problem is that when I try to execute any mmchnode command(as the ibm
