Migration to a tape migration level 2 volume

At the beginning of a level 1 to level 2 migration task, DFSMShsm selects the partial tape with the largest percentage that is written. This might be one of the following tapes:

The tape last used by this task
A tape ML2 volume from the list of not-associated, partially empty tape volumes
An empty tape (if available), but only if no partially empty tape is available

DFSMShsm selects tapes differently if you are using the duplex tape option for migration tapes.

DFSMShsm does not migrate a data set to a tape ML2 volume if the data set needs to be backed up.

When a tape unit and a tape volume are allocated, they remain allocated and mounted until the migration is completed or the volume becomes full or is needed by another function. When level 1 to level 2 migration is completed, the tape volume is deallocated and demounted.
