Cluster is already being monitored.

In my opinion there are 2 things to start with.

The application record entry in ONTAP. If there are too many it will not work.

If this is OK you need to check the database entries in all related tables´if there are entries left of the old record.

There are 10 application records, two of whcih are related to OCUM:-

CDC_Cluster2::*> cluster application-record show -fields name

vserver      name

------------ ----------------------

CDC_Cluster2 Advanced_Setup_Clicked

CDC_Cluster2 "app-OnCommand Unified Manager-1b25b4ae-e0bb-4582-8e51-8427c95f8362"

CDC_Cluster2 "app-OnCommand Unified Manager-c65ce198-e6f4-418e-88c8-5dbec977efe2"

is deleting the application records not service affecting ?

I can see old records of the cluster in OCUM, such as aggregate capacity (not up to date).

It was resolved by following the below KB :-

I had to modify the script to fit my case.
