"Unable to process the request due to a bad parameter" error when creating a replication in Cloud Director Availability 4.x

Products

• VMware Cloud Director

Issue/Introduction

Symptoms:

• When you attempt to create a new cloud to on-premises replication in Cloud Director Availability 4.x, the task fails with an error similar to:

Unable to process the request due to bad parameter 'settings.destination.site' -> '<destination site name>'

• This issue occurs when one or more of the virtual machines in the source vApp are being replicated to another on-premises site.

Environment

VMware Cloud Director Availability 4.x

Resolution

This is an expected behaviour. It is unsupported to replicate virtual machines within a single vApp to different on-premises sites.

Workaround:
If you need to replicate virtual machines within a single vApp to different destination sites, you must first separate the virtual machines into different vApps before configuring them for replication.
