Issue/Introduction

in VCF Automation 9 while looking at the data centers,  there is several disconnect and reconnect task. This shows that Aria Automation is getting disconnected from vCenter. 
vCenter Health DistributedDataStoreJob checker fails to get a response.


In  services-logs/prelude/mgtvcfauto-hffln/tenant-manager-1/vclistener/file-log-########.log we see the following exception information 

com.vmware.vcloud.api.presentation.service.InternalServerErrorException: Internal Server Error
        at com.vmware.vcloud.common.future.FutureUtil.convertExecutionException(FutureUtil.java:264)

Caused by: (vmodl.query.InvalidCollectorVersion) {
   faultCause = null,
   faultMessage = null
}

Environment

VCF Automation 9

Cause

This is caused by a tag added to 1 or more data stores connected to vCenter is tagged with vcd-distributed-catalog. 
DistributedDataStoreJob kicks in only if the datastores are tagged with "vcd-distributed-catalog" This API call is not connecting to vCenter 9 correctly. Which then causes a disconnect response in Aria Automation 9. 

Aria automation 9 connects to the vCenter and runs a data store check as part of the health check.  When a tag is added to data sore, the query tries to open a new API and this hand shake fails.  

Resolution

To work around this issue.

1. In vCenter remove the tag vcd-distributed-catalog from the data stores.
2. Then in Aria Automation on the data centers tab reconnect vCenter.

 

This will be resolved in Aria Automation 9.1
