vCenter Maintenance - Issue Non-ephemeral Portgroup
Hi Friends, We had a issue last day due a miss configuration. We used to keep our vCenters on ephemeral port groups for troubleshooting purposes in case of any issue. We have a new vCenter now and as per standards our project team put that on a portgroup which was named as "ephemeral", but it was quiet late we found it was not actually setup as an ephemeral port group, but static instead :(. So issue was a config issue, but I wanted to share how we solved it hopping it might help someone in other situations too. The story is like this. We planned to test an outage situation, by bringing down vCenter, to test if our VRA pre-build check can identify it. One of our lazy engineers went to Web Client of the ESXi server hosting vCenter and decided to turn the NIC off for the test. He received below error while turning it back on Description :- Reconfigure this virtual machine Virtual machine :- Non-PROD_vCenter State -: Failed - Invalid configuration for device '3
