Issue/Introduction

A Viptela site group is missing a device.

The device is seen under Monitored Devices inventory.

Checking the Data Aggregator device rest endpoint for the device:

http://<DA>:8581/rest/devices/<DADeviceID>

The rest output does not contain:

 <IsA name="SDN" rootURL="sdns"/>

The device does appear in the VNA inventory looking at the output of:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' 'http://VNAHOSTNAMEORIP:8080/vna/rest/v1/inventory' -o /tmp/inv.json

Cause

The device was deleted from the Data Aggregator, then rediscovered as SNMP.

Environment

Release : 3.7

Component : IM Reporting / Admin / Configuration

Resolution

VNA will only send new devices.

If a device is subsequently deleted from the Data Aggregator but still exists in VNA, you need to set the VNA gateway to Administratively Down the Administratively Up to perform the equivalent of a full sync with the VNA gateway:

Administration->Monitored Items Management->VNA Gateways
Select the VNA Gateway and click edit.
Set Administrative Status to Down and save.
Click Refresh until both Administrative Status and Operational Status is Down.
Select the VNA Gateway and click edit.
Set Administrative Status to Up and save.
Click Refresh until both Administrative Status and Operational Status is Up.

After some time (the device needs to sync from VNA -> DA, and then from DA->CAPC) check the Site group to verify the device now appears.

Additional Information

NOTE: Do not delete the VNA gateway as this will delete all the VNA items from the Data Aggregator
