How to Reassociate a Host with a VMM Server
Applies To: Virtual Machine Manager 2008, Virtual Machine Manager 2008 R2, Virtual Machine Manager 2008 R2 SP1
Occasionally, you might want to move one or more hosts from one Virtual Machine Manager (VMM) server to another. For example, you might want to consolidate hosts that are being managed by two or more VMM servers onto a single VMM server.
Alternatively, you might want to move one or more hosts back to a VMM server on which they had been previously managed but from which they have not yet been removed. In this situation, the hosts still appear in the Managed Computers pane of Administration view on the original VMM server. However, because the agents on the hosts have been reassociated with a different VMM server, the host status on the original VMM server is reported as Needs Attention in Hosts view and Access denied in the Managed Computers pane in Administration view. Before you can manage the hosts again on the original VMM server, you must reassociate the hosts with the original VMM server.
To move a host to a different Virtual Machine Manager server
In a VMM Administrator Console that is connected to the destination VMM server, click Add Host to start the Add Hosts Wizard.
On the Configurations Settings page, select the Reassociate host with this Virtual Machine Manager server check box. For more information about adding hosts, see Adding Hosts.
If you do not plan to move the host back to its original VMM server, remove the host from its original VMM server. For more information about removing a host, see How to Remove a Host (http://go.microsoft.com/fwlink/?LinkID=121827).
To reassociate a host with its original Virtual Machine Manager server
In a VMM Administrator Console that is connected to the original VMM server, in Administration view, click Managed Computers, and then select the hosts you want to reassociate.
In the Actions pane, click Reassociate.
The Reassociate command is enabled only when the status of an agent is reported as Access denied because it is no longer associated with the current VMM server.
In the Reassociate Agent dialog box, type the credentials of a domain account that has administrator privileges on the selected host.
