SCOM 2012 Monitoring Windows Cluster servers

SCOM 2012 Monitoring has 2 maintenance modes : SCOM Agents and Server Up/Down.

I would like to know when putting Windows cluster (SQL or Exchange) nodes in maintenance mode, which type of the maintenance mode they should be on?
I am not sure whether when manually failing over resources from one node to another if this will generate alerts. if so this might require SCOM Agents  maintenance mode.
When rebooting, I believe this requires Server Up/Down maintenance mode.

Any comments on my statement above to see if I am understanding well the SCOM maintenance modes.

    Accepted Solution

    When you failover certain services, the host obviously does not go down so Server Up/Down does not help much.

    You have to downtime only the services which are being failed over and also the ones which depend on this for a reasonable time only.

    For the SQL case, you should downtime services like the DB engine only.

    What about the SCOM Agents, would this trigger an alert ?

    You want to disable SCOM agents? This will generate alerts for sure.

    You can just disable the exact checks for 15 minutes or so.

    when you failover cluster resources would SCOM Agents trigger an alert ?

    Let me make sure you understood my question:

    Case 1: when I want to reboot a single server (which is not part of the cluster) , I can just use the Server UP/DOWN maintenance mode. Correct ?

    Case2: When I want to manually fail over resources from one server (an active  node which is part of the cluster to a passive node) then reboot the ex. active node that is now the passive. Do I need to enable both SCOM agents Maintenance mode as well as Server Up/Down Maintenance mode ?

    Case 3: When I want to just reboot a passive node of a cluster ( with no fail over  of any resources, seeing that as a passive node it has no resources at all). Do I need just to enable Server Up/Down maintenance mode Or I need to enable SCOM agents as well, considering the heart beat that might generate unwanted alerts?
