SCOM Maintenance Mode

scom

SCOM supports putting discreet objects/classes/targets into maintenance mode. This gives a very fine control over what objects/classes/targets have alerts forwarded or not.

Unfortunately, behaviorally, our operations team doesn't want that level of control.

Behaviorally they want to put the entire server, or groups of
servers, into maintenance mode. Where "maintenance mode" means no
alerting of any kind. Period. Fin.

Today, we come close, by putting WindowsComputer and HealthService (which also seems to cover Agent). Putting those objects into maintenance mode allows us to do application deployments (service stops, etc) and anything requiring a reboot.

However, we still get occasional alerts from objects in either like the Dell MP or BizTalk MP. Alerts that don't tend to target WindowsComputer, or anything in its inheritance chain(?).

We tried putting Entity object/class/target into maintenance mode but this seemed to send the RMS server into a tizzy. e.g. If we made 50 requests, for 50 different servers, maybe 1 in 5 would actually be placed into maintenance mode. The remainder would be ignored.

We are using the SCOM API via Power Shell, or the SCOM SDK object model, to put things into maintenance mode.

Is there a recommended way to put a server, and all its contained objects, into maintenance mode, reliably?

Is there something our team should be considering on why we don't want to put everything into maintenance mode?

Best Answer

According to the documentation, you can easily place a whole server in maintenance mode:

  1. In the Operations console, click the Monitoring button.
  2. In the Monitoring pane, expand Monitoring, and then click Computers.
  3. In the Computers pane, right-click the computer that you want to place into maintenance mode, click Maintenance Mode, and then click Start Maintenance Mode. You can use ctrl+click or shift+click to select multiple computers to place into maintenance mode.
  4. In the Maintenance Mode Settings dialog box, under Apply to, click Selected objects only if only the computer is to be placed into maintenance mode; otherwise, click Selected objects and all their contained objects.
