Duplicate Host IDs in Dell OMEVV Plugin

Products

• VMware vCenter Server

Issue/Introduction

In a VMware Cloud Foundation (VCF) or standard vSphere environment using the Dell OpenManage Enterprise Integration for VMware vCenter (OMEVV) plugin, you encounter the following issues:

• The Dell OMEVV plugin interface shows duplicate entries for the same ESXi hosts.
• Duplicate entries often appear with different Cluster IDs (e.g., a stale ID from a previous deployment) despite having the same cluster name.
• No duplicate host records are found in the vCenter Server inventory or the vCenter Database (VCDB) vpx_entity table.

Environment

VMware vCenter Server

Cause

This issue occurs when the Dell OMEVV plugin inventory retains stale metadata following a cluster decommissioning and subsequent redeployment. The plugin fails to reconcile the new cluster/host relationship with the historical records stored within the OME appliance, leading to duplicate Hardware Support Manager (HSM) references that block vLCM workflows.

Resolution

Verify vCenter Database (VCDB) Integrity

Ensure the issue is not within the vCenter inventory by running the following query against the vCenter PostgreSQL database:

1. SSH into the vCenter Server Appliance as root.
2. Access the database: /opt/vmware/vpostgres/current/bin/psql -U postgres -d VCDB
3. Check for duplicate host names: SELECT id, name FROM vpx_entity WHERE name = 'FQDN_OF_IMPACTED_HOST';
4. Since the vCenter database does not contain duplicate entries, the inventory must be refreshed at the plugin level. Please contact Dell Support for assistance with verifying the integrity of the plugin.
