When you perform operations and management (O&M) tasks, you can customize the execution time of the tasks. For example, you can customize the execution time of tasks for upgrading a cluster, adding nodes, upgrading versions, or changing the primary zone. This topic describes how to view or cancel a scheduled task in the console after you create the task.
