Issue/Introduction

New VNA Domains configuration fails with error "No discoverable User Domains Found!" at Spectrum OneClick.

Environment

Release : 22.2

Cause

VNA Server is not reachable with Hostname Specified.

Resolution

VNA Collector's IP is not configured in "/etc/hosts" file of VNA Aggregator , because of which VNA Collector is not accessible from VNA Aggregation Sever.

Update VNA Aggregation Sever "/etc/hosts" file with VNA Collectors IP.

And then  From Spectrum OneClick - Administration - VNA Configuration - Refresh the Domain Configuration.
It will list all the VNA Domains. 

Select the VNA Domain , map the landscape and Click on Discover.


Now Spectrum VNA synchronization works.

Additional Information

On VNA Aggregator server run the below CURL command to make sure that all VNA servers are accessible .
 
curl -k -u USER:PASSWORD -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' 
'http://<VNA_HOSTNAME>:8080/vna/rest/v1/admin/engines'

Output should show the Plugin with Running Status.
