vcenter change of IP?

[Adam231]

Hi,

Please excuse this if its a stupid question but I can't quite find the answer to this, I'm sure its out there but I can't quite find it

I have vcenter essentials plus with three ESXi v6 hosts and various VMs running. vCenter is running on one of the hosts and all is well.

My environment is split down into three different subnets for a variety of reasons, all there works well also. I had reason to move the change the VM hosting vCenter into a different subnet, essentially changing from 192.168.10.0/24 to 192.168.1.0/24. But as soon as the VM rebooted vcenter stopped working giving the attached error when trying to access from the web client. I could still connect to each host individually with the vSphere client but vCenter basically broke. As soon as I put it back to the original IP it started working again.

I know that the Management service needs restarted on each host after vcenter changes its IP, but there didnt seem to be any point in doing this as vCenter itself was inaccessible.

I am assuming there is something needing done on the vcenter server after a change of address but I can't quite figure that out.

Any help or pointers would be greatly appreciated!

Have you update the vCenter hostname IP address on DNS after the IP address change ? The vCenter Server services is running ? Any change you attach the vpxd.log ?

Richardson Porto,

Its AD integrated DNS so it updates at the DNS server automatically. On the client machine from which I run the vShpere Client or Web Client I flushed the DNS cache and ensured that ping was resolving to the correct new IP address. But even when RDP'd to the vCenter VM and running the web browser from there it still presents the previously attached error.

vCenter service is still running, no issues there.

Not sure how to get the logs for you, i googled and it references %ALLUSERSPROFILE%\VMWare\vCenterServer\logs which does indeed take me to the logs folder. I'm 'assuming' its the vmware-vpx folder, but what do you need from there and can I simply copy it out and zip it?

Thanks!
