Using uppercase in the ESXi FQDNs for Management Cluster will cause the Bringup workflow to fail

Products

• VMware Cloud Foundation

Issue/Introduction

Symptoms:

• If the ESXi FQDNs are in uppercase for the Management Cluster in the Bringup parameter sheet or json.
• The "Restore Lockdown Mode on ESXi Hosts" task fails during Bringup.

Environment

VMware Cloud Foundation 4.x

Resolution

This issue is resolved in VCF 4.1.

Workaround:
To workaround the issue follow the steps below along with re-imaging the host and starting a new Bringup workflow:

1. Download the attached ManagementClusterConfiguration.json file.
2. Take a backup/ snapshot of the Cloud Builder VM. 
3. Using a file transfer utility, replace the /opt/vmware/bringup/webapps/bringup-app/conf/workflowconfig/ems_recipes/ManagementClusterConfiguration.json file with the downloaded ManagementClusterConfiguration.json on the Cloud Builder VM.
4. Start the Bringup workflow in the Cloud Builder UI

Additional Information

Impact/Risks:
As the vCenter Server inventory will automatically add the ESXi FQDNs as lowercase, there is a mismatch between the uppercase value in VMware Cloud Foundation and vCenter.
