Products

• VCF Automation

Issue/Introduction

• When attempting to import a VMware Aria Automation cluster into VMware Aria Suite Lifecycle, the task fails at the watermarking stage. This issue is typically observed in the UI during the environment import or configuration process.
  
  
• The following error is displayed in the VMware Aria Suite Lifecycle UI:

Error Code: LCMVRAVACONFIG590097 - VMware Aria Automation watermark configurations failed. Check VMware Aria Suite Lifecycle logs for more information.

• In the vmware_vrlcm.log, under var/log/vrlcm the following exception is recorded:

com.vmware.vrealize.lcm.drivers.vra80.exception.VraVaProductNotFoundException: Either provided hostname: <vRA_FQDN> is not a valid VMware Aria Automation hostname or unable to run the product specific commands via SSH on the host.
...
Caused by: com.jcraft.jsch.JSchException: Session.connect: java.net.SocketException

• FQDN resolution and connectivity on Port 22 between LCM and vRA nodes are functional.

Environment

 

• Product: VMware Aria Automation 8.x

• Management: VMware Aria Suite Lifecycle

 

 

Cause

The failure occurs because the SSH fingerprint of the VMware Aria Automation appliance has not been accepted by the VMware Aria Suite Lifecycle appliance. The automated SSH driver used by the Lifecycle Manager fails to establish a secure connection when the host identity is not already present in the known_hosts file.

Resolution

To resolve this issue, you must manually establish the SSH trust between the appliances:

1. Log in to the VMware Aria Suite Lifecycle appliance via SSH as the root user.

2. Manually initiate an SSH connection to the VMware Aria Automation node identified in the error message:

   ssh root@<vRA_Node_FQDN>
   

3. When prompted with the authenticity of the host, type yes to permanently add the host to the list of known hosts.

   Note: You do not need to successfully log in to the Aria Automation node; simply accepting the fingerprint and seeing the password prompt is sufficient.

4. If you have a multi-node cluster, repeat this process for all nodes in the VMware Aria Automation cluster.

5. Return to the VMware Aria Suite Lifecycle UI and Retry the failed import task.
