Example of migrate output for Single to RAID-1
The migration path of raidtype Single to RAID-1 is a special case. Since the
single unit would become a mirrored array, technically this is not a migration.
As a result this command shows a different status than other migration paths.
In addition, the status of the newly specified disk will show DEGRADED
until the “migration/rebuild” is complete.
