MMNODYNUPGRD, Unable to use MM access method for region yyy until all database blocks are upgraded
MUPIP/Runtime Error: An attempt was made to use MM mode on a database that has not completed being upgraded. MM mode is only supported on fully upgraded databases.
Action: Use MUPIP SET FILE or MUPIP SET REGION with the ACCESS_METHOD parameter to set the access mode to BG. Then complete the file upgrade using MUPIP REORG UPGRADE. And finally set the access mode back to MM using the MUPIP SET FILE or MUPIP SET REGION command again.
