Maintenance Mode Schedules stop working

Question

I have a daily maintenance mode schedule setup so my dev/test servers go into a perpetual maintenance mode state. It's set to run for 1445 minutes so there's overlap and the schedule never expires, but it'll run for a day or so, and then stop. How can I correct this? SCOM 2016 UR7 on Windows Server 2016 with SQL Server 2016 SP2

Answer 1

Though this article is on How to suspend monitoring temporarily by using maintenance mode, you can get a clear idea on how to reverse it.

Answer 2

Hi @Brian W ,

I'm not sure what may be going wrong here, however I don't believe it's intended for a server to be constantly in maintenance mode.
There was a fix in Update Rollup 2 for SCOM 2019 regarding overlapping maintenance schedules:

Furthest end time during schedule overlap

In your case I suggest sibmitting feedback about this over at the SCOM uservoice page over here:

Answer 3

Imho if you are being asked to keep servers in mm indefinitely, then just remove them from scom and or from the management group that they need to be in mm constantly.

Answer 4

Hi,

For this issue, we can try 1439 or less to see if it works.

Hope the above information helps.
