Aggregates must be deleted from the Service Connector which will also delete disks from the cloud provider backend. Note: removing spare/orphaned disks is not the same as removing disks that are already part of an aggregate. As mentioned, disks assigned to an aggregate can ONLY be removed by deleting the aggregate itself.
