How to Update the VMM Agent
Applies To: System Center 2012 - Virtual Machine Manager
To ensure that all virtual machine operations run properly after the upgrade, you must update the VMM agents on virtual machine host computers. Use the following procedure to update the VMM agent on a virtual machine host after upgrading to System Center 2012 – Virtual Machine Manager.
To update the VMM agent of a host
In the VMM console, open the Fabric workspace, expand Servers, and then click All Hosts.
In the Hosts pane, right-click a column heading, and then click Agent Version Status. This adds the Agent Version Status column to the Hosts pane.
Select the host whose VMM agent you want to update.
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 have its VMM agent updated, the Host Status column for the host will display a value of Needs Attention and the Agent Version Status column will display a value of Upgrade Available.
Right-click the host whose VMM agent you want to update, and then click Update Agent.
The Update Agent button is enabled (not grayed out) only when the software version of the agent is older than the version of the VMM host.
In the Update Agent dialog box, provide the necessary credentials, and then click OK.
The Agent Version Status column will display a value of Upgrading. After the VMM agent has been updated successfully on the host, the Agent Version Status column will display a value of Up-to-date. And after you refresh the host again, the Host Status column for the host will display a value of OK.
You will see a Refresh host and an Update agent job in the Jobs workspace.
You can also update the VMM agent on 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.
