When you want to prevent the host from running any SnapCenter scheduled jobs, you can place your host in maintenance mode. You must do this before you upgrade the plug-ins. You might want to do this if you are performing maintenance tasks on hosts.
You cannot suspend the schedules on a host that is down because SnapCenter cannot communicate with that host.
After you complete host maintenance, bring the host out of maintenance mode by clicking Activate Schedule.
You can activate the schedule of multiple hosts simultaneously.
