Example of migrate output for Single to RAID 1
The migration path from RAID type Single to RAID 1 is a special case.
Because the single unit becomes 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 shows
DEGRADED until the “migration/rebuild” is complete.
For example, below is a system with two migrating units, /c0/u0 and /c0/u1.
Unit u0 is migrating from a RAID 10 to a RAID 0 unit, while unit u1 is
migrating from Single to a RAID 1, initiated by the following commands:
/c0/u0 migrate type=raid0
/c0/u1 migrate type=raid1 disk=5
