vCenter server hardware has failed and two vSphere server are still associated with that server. Looking to disassociate both servers with the old vCenter and establish a new connection with the new vCenter server.
Environment:
ESXi 5.1 server (production)
ESX 4.1 server (production)
vCenter 5.1 server (no longer exists/dead) appliance running on separate ESXi 5.1 server
Scenario:
vCenter 5.1 server managing both production vSphere servers above. The hardware which housed the vCenter server failed and is unrecoverable. Both servers are accessible using the vSphere client.
The ESX 4.1 server I receive the following message when using the vSphere client: "This host is currently being managed by the vCenter Server with IP address X.X.X.X. Changes made to this host during this session may now be reflected in vSphere Client sessions currently viewing the vCenter Server." Host Management, under the Summary tab displays: "This host is currently managed by vCenter Server X.X.X.X."
The ESXi 5.1 server did received the same message when using the vSphere client until I chose an option under Host Management to disassociate or disconnect with the vCenter server (can't remember exactly what the option was). This was successful, to a degree. When logging into the ESXi 5.1 server, it does not present the message stated with the ESX 4.1 server.
Another vCenter server was installed in an attempt to restore centralized management with no success. Adding either server as a host to the datacenter yields the following error message: "Cannot contact the specified host (server7). The host may not be available on the network, a network configuration problem may exist, or the management services on this host may not be responding."
Goal:
To disassociate both servers with the old vCenter and establish a new connection with the new vCenter server.
Any assistance would be appreciated.
Thank you.
