Standby Mode powers off an vSphere host and allows it to be powered back on again through Wake-on-LAN protocol triggered either manually or automatically by vCenter Server. ## Causes Do not disconnect a host in standby mode or move it out of the DRS cluster without first powering it on, otherwise vCenter Server is not able to power the host back on. ## Resolutions Power the host on using a different method and then disable VMware DPM on that host until you the issue is resolved.
