My network team is doing tech refresh and they decided that along with hardware change, they want to change IP range. Hence I was tasked to perform re-IP of vCenter.
You can read how to change IP of VCSA here : https://angrysysops.com/2021/03/25/vsphere-7-how-to-change-the-fqdn-and-ip-pnid-address-of-vcenter-server-appliance/.
I had to consider how to access my VCSA once I put it in to new portgroup on the new VDS. In order to have accessibility I added extra NIC to print server and put that NIC in new portgroup with IP of VCSA subnet. In this way I had Layer 2 connectivity.
For my bad luck the print server was located on the ESXi host which had connectivity issues due to port misconfiguration. Although I set up everything correctly, I lost my VCSA.
Now in this video I will show you how to recover if you mess up with IPs, or portgroups. Enjoy and learn 🙂
