Rolling restart of services

To reduce or eliminate downtime for services with multiple instances, Control Center restarts instances of the service one at a time.

The Control Center browser interface visually indicates when a service is restarting and whether an instance is down during the restart. When a wide area network (WAN) outage occurs, the rolling restart proceeds, with instances on the disconnected hosts restarting when the WAN is restored.

The serial process applies to restart only. When stopping and starting services, Control Center starts and stops all instances immediately.

Optionally, you can specify that Control Center is to stop all instances of a service before restarting.
