This host is currently being managed by the vCenter Server

[Phil_LeMaster]

I have ESXi v5 installed and was testing the vCenter Server software on a standalong server and connected up to ESXi5. I later blew away the server software to test something else.

Now when I log into ESXi Server with vSphere Client I get the message "This how is currently being managed by the vCenter Server with IP address ????

How do I remove the vCenter info from ESXi so I don't receive this message?

Thanks

I'm having same problem. Do I need to delete the old VCenter in order to remove it from the managed hosts?

Thanks

You need to remove the HA and VPXA agents from the ESXi host via vCLI.

[Dave Morera]

SSH into the host
Delete the vpxuser user account (used by vCenter for communication)  –> userdel vpxuser

Go into the uninstaller directory –> cd to /opt/vmware/uninstallers
Remove the HA/aam agent –> ./VMware-aam-ha-uninstall.sh to
Remove the vCenter agent –> ./VMware-vpxa-uninstall.sh to

Will this delete the Workstations or any information/data from the hosts?

Thanks

[Dave Morera]

It removes the agents and user that vCenter install/creates when you connect a host to vCenter.

I tried to remove both agents but it gives me not found.

Do I need to remove the old Vcenter from the inventory?

Thanks,

[Dave Morera]

You still have a vCenter? The initial post said that vCenter was gone. 

[palester90]

I turned off the old Vcenter and created a new Vcenter. But if I logged in to the host, it still gives me error that the host is still managed by old Vcenter IP. Do I need to delete the old Vcenter and do the ssh command?

Thanks

[Dave Morera]

Is the new vCenter using the same database as the old vCenter? If so, go to Home>vCenter Server Settings>Runtime Settings and make sure the correct vCenter name is entered.

[palester90]

They have different database.

[Dave Morera]

Have you tried removing it from the (new) vCenter and reconnect it?

[Phil_LeMaster]

I removed the user but your info is for ESXi 3.5 and ESXi 4. I am on ESXi 5

Note: vpxa cannot be uninstalled on an ESXi 5.0 host as it is now a part of the esx-base package.

Any other ideas?

[Dave Morera]

Did you restart the management service? 

[Phil_LeMaster]

It's the small things that you forget to do.

That fixed it - Thanks

Hello,

This is what happened to mine. I am using esxi5 and my old vcenter messed up. I decided to uninstall the vcenter and reinstalled it but stop me to installing it and gave me error that port 443 and 80 are being used. I decided to create a new Vcenter and when I tried to connect it gave me error. I put new IP address on the new vcenter and when I opened the host, it is giving me error: that the host is being managed by my old vcenter IP Address. Do I need to remove the old vcenter from the inventory and delete the user? Pls. advise.

Thanks,

[Phil_LeMaster]

This is what I did for ESXi 5 based on prior posts.

I removed the vpxuser account and then went to the ESXi console and restarted the management service.

How do i delete vpxuser? O i delete them from the host or from command?

Thanks,

[Phil_LeMaster]

The easiest way is to login with vSphere Client select the host  Local Users & Groups and remove the user or

SSH into the host
Delete the vpxuser user account (used by vCenter for communication)  –> userdel vpxuser

To restart the management agents on ESXi:

1. Connect to the console of your ESXi host.
   
2. Press F2 to customize the system.
   
3. Login as root.
   
4. Use the Up/Down arrows to navigate to Restart Management Agents.
   
   Note: In ESXi 4.1 and ESXi 5.0, this option is available under Troubleshooting Options.
   
   
   
5. Press Enter.
   
6. Press F11 to restart the services.
   
7. When the service has been restarted, press Enter.
   
8. Press Esc to log out of the system.

Hi,

Do I need to delete all the users from local Users & Groups? I have nfsnobody, daemon, root, & dcui from my users. Which user i need to delete?

Thanks,

[Phil_LeMaster]

You only delete the vpxuser for Local User & Groups.

[palester90]

Does it mean vpxuser is User or root? Sorry for too much questions.

Thanks,

[palester90]

Thank you very much for your help. I just restarted the management agent and it didnt asked the managed IP Address.
