Nikesh, The case you are trying is supposed to fail. You have a volume of type dothill_realstor1 which is defined to say "this volume must be on backend DotHill_RealStor1". This is a requirement that you defined for that volume. Now you want to migrate it to realstor2, which is a violation of the requirement that you specified. To migrate it, you should change the volume type (retype), which changes the requirement.
