Issue/Introduction

After upgrading Spectrum and VNA to version 21.2.2, the status for all domains on the OneClick integrated with VNA is  "Waiting for VNA response".

I already fixed the missing username / passwords on the VNA side and all collectors show as "connected" on the VNA aggregator as described here:

https://knowledge.broadcom.com/external/article?articleId=222519

However, the status is unchanged for five hours now.  It seems like the issue described in

https://knowledge.broadcom.com/external/article/199594/unable-to-receive-alarms-in-spectrum-fro.html, but this is supposed to be fixed since NetOps 20.2.

The mysql output from the VNA Aggregator "mysql> show full processlist;" shows all VNA aggregator Daemons with a Sleep State.

 

 

Cause


Trouble shooting done:

- Verified the Aggregator to VNA collectors communication and do not see any issue
- After a manual on-demand sync from Spectrum no request was received to Aggregator and all domains are shown waiting for sync to complete.
- Restarted the OneClick server but the aggregator still has received no request.  
- Enabled runtime debug on the OC web server  “VNA Integration Information” 

After analyzing the spectrum OC tomcat logs, we identified the hostname is changed from FQDN to a short name.  The checkForActiveServer is false - the host name  does not match.
from tomcat log.

Environment

Release : 21.2

Component : Spectrum Integrations

Resolution

Updating the SDN_Enabled_OC_Server with FQDN the issue is resolved.  SDN_Enabled_OC_Server (0x6730005) is on SDN Manager model.
