All

When you attach an existing Amazon EBS volume to an instance type that requires SRD for the first time, Amazon EBS automatically modifies the existing volume. Then, Amazon EBS moves the volume to an SRD-capable infrastructure. You can apply only one modification at a time to a volume. If you try to attach your volume when a modification is happening on the volume, then Amazon EBS can't move the volume to the SRD-capable infrastructure.
