I have a CentOS 6 box that has two IP Addresses on one physical interface - One the IP assigned to the interface via the netconfig scripts, and the second a "virtual" IP assigned to the same interface via a pacemaker service. I would like to change the "physical" IP address, but I don't want to disrupt any connections to the virtual IP address. Is this possible, and if so, how?
Always before when I wanted to change an IP, I would simply modify the netconfig script and then run
service network restart, but I would think that would terminate any connections to the virtual IP.
