vCenter Server Maintenance and Failover

If you perform maintenance on the vCenter Server (for example, if you want to stop the vCenter process, shut the server down, reboot it or disconnect from the network) and failover is not desired, set the Veeam link to vCenter or vSphere Host object in maintenance mode (for details, see Maintenance Mode Synchronization). This will prevent the Veeam VMware: Connection lost to VMware vCenter Server monitor from triggering the failover script.
