You can change the RAID levels of currently defined logical devices.
Note:
Only valid RAID level migrations appear in the list. Migration requirements for each RAID level are described here.
Note:
When you add drives, the migration wizard
shows the current layout of the data, including the current logical device size. For most migrations,
you will need to increase the logical device size setting; the default size is not generally adequate once you add drives or segments.
