[gpfsug-discuss] Changing ip on spectrum scale cluster with every node down and not connected to network.

[Andi Rhod Christiansen]

Hi Jonathan,

Yes I thought about that but the system is located at a customer site and they are not willing to do that, unfortunately.

That's why I was hoping there was a way around it

Er, yes it is. Spin up a new temporary VLAN, drop all the ports for the cluster in the new temporary VLAN and then bring them up. Basically any switch on which you can remotely down the ports is going to support VLAN's. Even the crappy 16 port GbE switch I have at home supports them.
