Start the virtual machine.Unplanned SwitchoverAn unplanned switchover is necessary when a failure of some sort occurs and either the source system isunavailable or the connection between the systems is broken and requires that the virtual machine be broughtonline on the target server.Since, in this scenario, the source server is unavailable for some reason, quiescing the data on the sourceserver is not possible and as such, only the following steps are necessary on the target server to bring thevirtual machine online.1. On the target server, start the DataKeeper console as described previously.2. Select the mirror and click Switchover in the Actions pane.Wait until the mirror has completely come into service on the server and the DataKeeper user interface(UI) indicates the functional server is the source server.3. On the same server, start Hyper-V Manager as described previously.DataKeeper for Windows Technical DocumentationPage 152
