So I have two switches.

All 3 of my HCI oVirt servers are connected to both switches.

1 switch serves the ovirtmgmt network (internal, gluster communication and everything else on that subnet)

The other switch serves the "main" front-end network (Private).

It turns out that my datacenter plugged the switches into the wrong power supplies, and now needs to move them.

My switches have single PSUs, so when we move them, the network will go down.

Obviously, I'm just going to move 1 switch at a time.

What I'm wondering, though, is there's an "easy" way to force all the traffic for both networks out one of the single interfaces, so that I don't experience any more downtime during this switch maintenance.

Should I assign another temporary IP address on each of the interfaces for each server that is in the same subnet as the switch we're going to take down?
