Maintenance Mode changes in SCOM 2012

Operations Manager 2012 still doesn’t block placing management servers into maintenance mode. However, the way Management Servers behave when placed into maintenance mode has changed:

    • If a Management Server is placed into Maintenance Mode then the System Center Management Configuration Service will change the agent assignment to force the agents to failover to another management server so data loss will not occur.


  • In Operations Manager 2007 a Management Server couldn’t take itself out of Maintenance Mode as Maintenance Mode unloads all workflows (including the “End Maintenance Mode” workflow). This has changed in Operations Manager 2012 by assigning the “End Maintenance Mode” workflow to the “All Management Servers” resource pool. This way the workflow will failover to another Management Werver and reload to be able to exit maintenance on the Management Server that was placed into Maintenance Mode.Note: If you only have one Management Server and you place it into Maintenance Mode it will never come out because there is no other Management Server for workflow failover.
