Committing a batch migration
The migration process inserts a temporary RAID 1 structure above the source devices with the target devices as an out-of-date
leg of the RAID 1. Migration can be understood as the synchronization of the out-of-date leg (the target).
About this task
After the migration is complete, the commit step detaches the source leg of the RAID 1 and then removes the RAID.
The virtual volume, or device is identical to the one before the migration except that the source device is replaced with the
target device.
A migration must be committed in order to be cleaned.
When the batch migration is 100 percent complete, use the batch-migrate commit command to replicate the volumes on
the target devices and remove the volumes from the source devices.
To commit a batch migration, perform the following:
