## Notes on Maintenance Mode Tracker

1. Put a vSphere host in maintenance mode in vCenter.
2. OpsMgr responds by:

   1. Setting Host Maintenance Mode Sync object to Warning, and raises warning alert “Host entered Maintenance Mode”
   2. Running the script to put Host and child objects in OpsMgr maintenance mode.
   3. These child objects of host will NOT go in OpsMgr maintenance mode — the Maintenance mode Sync object itself, and the VM-Container object (including contained VMs).

3. The Host will stay in OpsMgr maintenance mode for as long as the timer parameter on the monitor (default 24 hours), if the Monitor timer expires (default 24 hours) the rule can be enabled that will re-trigger maintenance mode script to extend the duration. This rule is not enabled by default and should be enabled manually.
4. When the host is removed from maintenance mode in vCenter

   1. Host Maintenance Mode Sync object state will go green, Maintenance mode alert will close
   2. Script will take Host and child objects out of OpsMgr maintenance mode
   3. Normal monitoring of this host will resume
