Maintenance mode allows you to set a SCOM object to a suppressed state, allowing you to complete work on the object without additional alerts and errors being generated.
Maintenance mode allows you to set a SCOM object to a suppressed state, allowing you to complete work on the object without additional alerts and errors being generated.
Objects that can be put into maintenance mode in SCOM (single objects, groups, DAs, EAs, etc.) have a convenient maintenance mode button on their drilldown in SquaredUp DS for SCOM. You can put the object into maintenance mode just by clicking the button.
How to identify if an object is in maintenance mode
When an object is in maintenance mode, you'll see maintenance mode next to its name on the object's drilldown.
The health icon will have a wrench icon overlayed. The same icon will also be displayed in tiles that show a health status for objects, such as the Status tile.
Does putting an object in maintenance mode affect its contained objects?
When you put an object into maintenance mode in SquaredUp DS for SCOM, all contained sub-components (such as disks, software, or group members) are also placed into maintenance mode.
Note for Enterprise Applications (EAs): Putting an Enterprise Application (EA) into maintenance mode will also put the Dependencies into maintenance mode. Since you usually don't want all Dependencies in maintenance mode, the better way to do it is to put the individual components of the EA into maintenance mode. For example, if you want to put the components that make up your application and all the availability tests into maintenance mode, drilldown to the Map and Availability objects and put them into maintenance mode, but leave the Dependencies.

SCOM 2016 and above have a Maintenance Schedules feature which allows you to schedule one off or regular maintenance windows. This option is available to SCOM admins and can be accessed from the SCOM console under Monitoring > Maintenance Schedules.
In the preview versions of SCOM 2016, Maintenance Schedules was available under the Administration section.
A good walkthrough of setting up a recurring maintenance mode for servers on "Patch Tuesday" can be found here.
