Solve Maintenance mode Conflict by use the furthest end time.
Best way to explain is an exemple.
I put a logical drive in Maintenance Mode for 60 Min.
If my collegue put the windows Computer in maintenance WITH Child Iems for 15 min during my maintenance, My logical disk will be out of maintenance a the end on the Computer Maintenance.
Normaly i expect the maintenance on my Logical disk should be end at his scheduled end time MINIMUM never Before.
