How do I lock the OLC state?
Purpose
You can lock the OLC state of a child object that is in maintenance mode to prevent the OLC state from changing in the event that the parent object OLC state changes to In Service. Locking the OLC state of an object disables any associated scheduled OLC state change. Also, when the OLC state of an object is locked, you cannot configure the Revert OLC State parameter of the object.
Note: You can lock the OLC state of multiple objects at once.
