Issue/Introduction

Duplicate records for vCenters in the Operator Console (OC) Inventory have been identified. This is causing duplicate models to be imported into Spectrum. There is a need to find out why NISAPI retrieves duplicate records for vCenter. One looks like it's coming from the UIM Robot and another one from the vmware probe.

Environment

• Release:  20.4.x or higher
• Component: UIM - VMWARE

Cause

• discovery_server correlation, use of VirtualID in 'unmatch_on_any' rules

Resolution

Example:

1. On cs_id 84xxx: (Virtual machine/Robot)

   <attributes key="VirtualID" value="500b9845-xxxx-90a2-664d-42xxxxeb66e8"/>

2. On cs_id 560xxx: (vCenter)

   <attributes key="VirtualID" value="89e2c349-xxxx-4f96-b7c6-a5dxxxxe7977"/>

3. If you examine the <rules> section in the discovery_server.cfg, and then remove VirtualID from all of the 'unmatch_on_any' rules, then save the file, then cold start the discovery_server, it should resolve the dupes.
