Updated: May 13, 2016
Applies To: System Center 2012 R2 Virtual Machine Manager
After you upgrade Virtual Machine Manager (VMM) to System Center 2012 R2, use the following procedure to reassociate a virtual machine host with the VMM management server.
To reassociate a host
In the VMM console, open the Fabric workspace, expand Servers, and then click All Hosts.
In the Hosts pane, ensure that the Agent Status column is displayed. If the Agent Status column is not displayed, right-click a column heading, and then click Agent Status.
Select the host that you need to reassociate with the VMM management server.
Tip
You can use the SHIFT key or the CTRL key to select multiple hosts.
On the Hosts tab, in the Host group, click Refresh.
If a host needs to be reassociated, the Host Status column for the host will display a value of Needs Attention, and the Agent Status column will display a value of Access Denied.
Right-click the host that you want to reassociate, and then click Reassociate.
In the Reassociate Agent dialog box, provide the necessary credentials, and then click OK.
The Agent Status column will display a value of Reassociating. After the host has been reassociated successfully, the Agent Status column will display a value of Responding. And after you refresh the host again, the Host Status column for the host will display a value of OK.
Tip
You can see a Reassociate agent job in the Jobs workspace.
After you have reassociated the host, you will most likely have to update the VMM agent on the host. For more information, see How to Update the VMM Agent.
Note
If you have installed System Center 2012 R2 Virtual Machine Manager Update Rollup 7 (or later) and the host has virtual machines that were part of a service or a VM role, see Re-associate Orphaned Virtual Machine with its Service Instance or VM Role using System Center 2012 R2 with Update Rollup 7.
Note
You can reassociate a VMM library server in a similar manner. To view a list of VMM library servers, open the Fabric workspace, expand Servers, and then click Library Servers.
