1-2-5-2 Volume migration reserve

When the CreateMigrationTask is used to execute a migration task, a volume migration reserve is

performed for the migration source volume and migration target volume specified in the migration plan.

A volume migration reserve is released either when the migration terminates normally or the migration

task changes to a terminated status, or when the Cancel command is executed to cancel the migration

task. Refresh processing releases the volume migration reserve when the migration task ends with a

failure.

1-2-5-3 Swapping controller LDEV numbers for migration source volumes and migration

target volumes

Once migration terminates normally, the controller LDEV number of the migration source volume and the

controller LDEV number of the migration target volume are swapped.

1-2-5-4 Deleting (erasing) migration source volume data

If the erasedata parameter of the CreateMigrationTask command is set to either Yes or omitted,

the migration source volume data is deleted when migration terminates normally.
