"Internal Server Error" when loading Identity & Access in Fleet Management UI

Products

• VCF Operations

Issue/Introduction

Symptoms:

• The Access & Identity tab displays a blank page or a 500 Internal Server Error banner.
• Identity provider details fail to load or save.
• You observe the following error in the UI or browser developer tools:

{"message":"Identity Internal Server Error","code":"IDENTITY_INTERNAL_SERVER_ERROR","status":500}

Environment

VCF Operations 9.x

Fleet Management 9.x

Cause

The issue is caused by a data node in the VCF Operations cluster remaining in a "Waiting for Analytics" state. While the analytics service may appear as "running" via an SSH console, the cluster is only partially online. This inconsistent state prevents the API from returning a successful 200 response to the Lifecycle Manager interface, resulting in a timeout or 500 error.

Resolution

To resolve this issue, you must perform a clean restart of the cluster to ensure all nodes reach a fully online status.

Follow these steps in order:

1. Log in to the VCF Operations Admin UI (https://<vcf_ops_fqdn>/admin).
2. Select the option to force the cluster Offline.
3. Confirm that all nodes are offline and the cluster state reflects Offline.
4. Power off all virtual machine nodes in the cluster through the vCenter Server.
5. Power the nodes back on using the proper sequence (Primary Node, then Replica, followed by Data and Witness Nodes).
6. Log back into the Admin UI and bring the cluster Online.
7. Monitor the cluster and ensure no nodes remain in the "Waiting for Analytics" state.
8. Once the cluster is fully online, log in to Aria Suite Lifecycle and confirm the Access & Identity Management UI is working properly.
