Reconfigure your VMs following a vSphere Replication Failover

By Tony Reardon 2 Mar, 2020 Leave a comment

Unfortunately were not always lucky enough to have an awesome product like SRM to manage DR for us and we have to make do with the tools we have available. While vSphere replication will allow you to automatically replicate VMs between sites, that’s about it… once you fail over, it can be a long manual process to reconfigure each of your VMs to get them back online.
To help speed this process along, I’ve put together a little menu system that will list all of your replicated VMs and then give you a variety of options to reconfigure them following a failover.

Note: This requires a lot of initial manual configuration which isn’t ideal but its a lot easier to do this at your leisure now than when scrambling around for IPs etc. during a DR event.
