Issue/Introduction

Spectrum is not receiving any VNA Alarms after Spectrum Landscape Migration.

Cause

Spectrum Server migrated to a new server with different hostname.

Resolution

When the VNAGatewayHost Model is created on the landscape the VNASiteConfiguration 0x6730089 attribute contains landscape mappings for each VNA Domain - <landscape>landscapenamehere</landscape>

On the migrated Spectrum Landscape(s) this value needs to be updated to reflect the new Spectrum server name for each VNA Domain that has the old value.

Then recycle Tomcat on the OneClick Server that is integrated with VNA.
