Description
The migration process inserts a temporary RAID 1 structure above the source device/extent with the target device/extent as an
out-of-date leg of the RAID 1. The migration can be understood as the synchronization of the out-of-date leg (the target).
After the migration is complete, the commit step detaches the source leg of the RAID 1 and removes the RAID 1.
The virtual volume, device or extent is identical to the one before the migration except that the source device/extent is
replaced with the target device/extent.
A migration must be committed in order to be cleaned.
CAUTION: Verify that the migration has completed successfully before committing the migration.
Examples
Commit a device migration:
VPlexcli:/data-migrations/device-migrations> commit -m beta_device_mig1 -f
Committed 1 data migration(s) out of 1 requested migration(s).
