I am trying to remove devices from the Operator Console, and they are not being removed.
Release: 20.4+
Component: UIM Operator Console - Inventory
The data_engine was running in a secondary state, and was not running on the HA server. Therefor the discovery server could not remove the devices.
Follow document:
data_engine on primary does not appear to be functioning correctly after an HA failover failback
