Before you begin
You must have the Application Administrator or Storage Administrator role.About this task
During a maintenance window, the events related to all objects on that cluster are still generated, but they do not appear in the event page, and no alerts or other types of notification are sent for these events.
The time you enter for the maintenance window is based on the time at the Unified Manager server.
Procedure
-
In the left navigation pane, click .
- In the Maintenance Mode column for the cluster, select the slider button and move it to the right.
The calendar window is displayed.
- Select the start and end date and time for the maintenance window and click Apply.
The message Scheduled
appears next to the slider button.
Result
When the start time is reached the cluster goes into maintenance mode and an
Object Maintenance Window Started
event is generated.
