After the migration I ran the "Retype" operation to change the volume type to the new type "xio_190_iscsi" -
cinder retype cc1027a3-
The volume type does not change. I checked the logs and the operation failed with the following error message.

It appears that the Retype operation wants to perform a migration even though the migration policy is set to on demand.
Cinder team, can you check this?
