You can change the reservation or storage setting for a managed machine. This ability is useful when a machine moves to a new storage path that is not available in its current reservation. For a single machine deployment, you can also change the business group for the machine.

You can move a machine in a single machine deployment to a different business group if the machine owner is a member of the target business group. You must be a business group manager of the original and the target business group to change the business group setting.


If there is a reservation policy assigned to the machine, you cannot change its business group.

You can create additional reservations for the associated compute resource by using the Administration > Compute Resource menu options.

Storage and memory that are assigned to a provisioned machine by a reservation are released when the machine to which they are assigned is deleted in vRealize Automation by the Destroy action. The storage and memory are not released if the machine is deleted in the vCenter Server.

For example, you cannot delete a reservation that is associated with machines in an existing deployment. If you move or delete deployed machines manually in the vCenter Server, vRealize Automation continues to recognize the deployed machines as live and prevents you from deleting associated reservations.

If changing the reservation will move a machine in vCenter Server to a new storage path that is not part of that machine's reservation in vRealize Automation, verify that the target or new storage path is selected in the machine's target reservation before you change the machine's reservation.
