In order to remove Flash Pool from an existing aggregate, you would first need to migrate the volumes (data) to a different aggregate before destroying the existing Flash Pool aggregate. The SSDs will then be returned to the spares pool for the system. It is possible to disable caching of the Flash Pool for testing purposes.
