Thanks for the clarification ... I figured that was what you were talking about but just wanted to be sure :) Yes, your plan should be fine, as long as the Test Shutdown actually simulates no power (battery drain) and not just sending the Shutdown signal.
Hello Can anyone help? We have a Dell PowerEdge T620 running Server 2008 R2 with two virtual servers (SBS 2011 and Server 2008 R2) in Hyper - V. The PowerEdge isattached to a Dell UPS Rack/Tower 2700w 3U. Dell UPS Node Manager has been used to configure the UPS. The setup facilitates graceful shutdown the virtual servers before Hibernating the hostserver. The intention is that in a power outage the servers are shutdown when the battery is depleted and then restarts when power is restored. However, according to Microsoft, Hibernate is disabled where Hyper-V is used. The impact is that the UPS attempts Hibernation, fails and enables shutdown. It is then necessary for a manually switch-on of the server. The virtual servers will then automatically restart. It is highly undesirable to have to manually switch on the host server. Does anyone know how a restart can be enabled? Thank you in advance.
