Upload Failed when installing Management Pack for Horizon in Aria Operations

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

When attempting to install or reinstall the Management Pack for Horizon (MP4H) v2.7.0 in Aria Operations 8.18.7, the process fails during the PAK file upload phase.

Symptoms:

• Browser displays "Upload Failed" error message.
• Issue persists when using the local "admin" account.
• The file LimitRequestBody 0 is already present in vcops-photon-apache.conf.

Environment

• VMware Aria Operations 8.18.7
• Management Pack for Horizon v2.7.0

Cause

The UI-based upload fails due to browser timeouts or network interruptions during the distribution of large management pack PAK files across the cluster nodes.

Resolution

To bypass UI upload constraints, use the Suite API to manually upload the management pack:

1. Log in to the Aria Operations Suite API (https://<aria_operations_fqdn>/suite-api).
2. Send a POST request to the endpoint /api/solutions/upload.
3. Attach the Management Pack PAK file to the request.
4. Once the upload succeeds, navigate to the Repository tab in the UI to complete the installation.
