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 documentation states) the command fails, and that makes sense as the ip on the interface has been changed without the deamon knowing.. But is there a way to do it manually within the configuration files so that the gpfs daemon updates the ips of all nodes within the cluster or does anyone know of a hack around to do it without having network access. It is not possible to turn on the switch ports as the cluster has the same ips right now as another cluster on the new switch. Hope you understand, relatively new to gpfs/spectrum scale Venlig hilsen / Best Regards Andi R. Christiansen
