Changing the heuristic IP address 6 years 8 months ago #1400

I want to change the heuristic IP address. We need to do a reset of our switch and worried that neither of the 2 hosts will be able to ping the heuristic IP address.

I can simply change the heuristic IP to something like 8.8.8.8 but as there will be possible switch downtime (so neither of the 2 hosts can access the IP for a short period of time) - Will this affect the HA pool? What is the steps to securely change the IP without any possible issues?

That parameter is only used during an ha event, so it is safe to change on a running system. If you want to be totally safe you can disable halizard, make the change and then reenable
