VNA Integration not finishing its discovery after upgrade to 21.2.2

Products

• CA Spectrum

Issue/Introduction

VNA Integration is not working since the Environment was upgraded to 21.2.2, the Discoveries are not completing and are in a hung status.  We see many times HTTP 500 errors from OneClick when we try to reach the VNA Configuration page.

 

Environment

Release : 21.2.x

Component : Spectrum Integrations

Cause

Performance Manager and VNA are integrated on the same OneClick server

Resolution

As from the Spectrum OneClick, PM and VNA are integrated on the same server, we had to disable PM until the VNA discovery completed as the every 5 minute incremental synch with PM to Spectrum OC seemed to interrupt the VNA discovery.
