Adding datasources to AIQUM 9.18 fails

Hey NetApp Community,

Just sharing this, hopefully it helps other customers if you encounter an issue with AIQUM 9.18 when attempting to add a datasource and receive the following error:

Unable to add cluster datasource. This can occur if the clocks on the systems are not synchronized and the Active IQ Unified Manger HTTPS certificate start date is later than the date on the cluster, or if the cluster has reached the maximum number of EMS notification destinations.

In the "C:\ProgramData\NetApp\OnCommandAppData\ocum\log\ocumserver.log" file you will notice the following error:

2026-06-30 12:14:57,463 ERROR [admin] [default task-15] [c.n.o.r.m.e.GlobalExceptionHandler] Server returned HTTP status 500.HTTP error message :{"timestamp":"2026-06-30T02:14:56.724+00:00","status":500,"error":"Internal Server Error","path":"/acquisition-api/server/datasource"} com.netapp.dfm.collector.OcieException: Server returned HTTP status 500.HTTP error message :{"timestamp":"2026-06-30T02:14:56.724+00:00","status":500,"error":"Internal Server Error","path":"/acquisition-api/server/datasource"}

Which is similar to this KB (but not the actual issue) https://kb.netapp.com/data-mgmt/AIQUM/AIQUM_Kbs/Unable_to_add_cluster_on_AIQUM_RHEL_due_to_missing_acquisition_user

In the "C:\ProgramData\NetApp\OnCommandAppData\ocie\log\server_acq.log" file you will notice the following error:

Error Payload from ONTAP: {"error":{"code":"983115","message":"Cannot complete the operation because the filter rules will exceed the maximum rules count (256)."}}
