VMware Identity Manager Connection status displays as Down in NSX Manager

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• Authentication to VMware NSX Manager via VMware Identity Manager (vIDM) fails.

• Other products residing on the same subnet as vIDM (such as VMware Aria Operations) authenticate successfully.

• When navigating to System > User Management > Authentication Providers > VMware Identity Manager > VMware Identity Manager Connection in the NSX Manager UI, the status displays as Down.

• Network troubleshooting steps, such as ping or traceroute executed from the NSX appliance CLI, fail to reach the VMware Identity Manager cluster.

Environment

• VMware NSX

• VMware Identity Manager (vIDM)

Cause

This issue is caused by a lack of network connectivity between the NSX Manager and the VMware Identity Manager cluster. Specifically, this occurs when the two components reside on different subnets and the necessary routing configuration (such as a BGP route) is missing or has not been re-established following a network event.

Resolution

Procedure

To resolve this issue, you must restore network connectivity between the affected subnets.

1. Log in to the NSX Manager UI.

2. Navigate to System > User Management > Authentication Providers > VMware Identity Manager > VMware Identity Manager Connection to confirm the current status is Down.

3. Engage your network administrator to review the routing configuration between the subnet hosting the NSX Manager cluster and the subnet hosting the VMware Identity Manager cluster.

4. Identify and restore any missing routes (such as BGP routes) required to allow traffic between these subnets.

5. Once routing is restored, return to the NSX Manager UI path listed in Step 2.

6. Verify that the VMware Identity Manager Connection status now displays as Up.
