For example, if you migrate the RAID level of a array from RAID 5 to RAID 0, the Modify Array wizard lets you remove drives from the existing configuration to enable the RAID level transformation.
Select Remove drives in the Modify Array window, and click Next.
The Modify Array window appears and it states the number of drives that you must remove to change the RAID level from the current level to a new RAID level and the maximum number of drives that can be removed.
Click the icon to remove the drives.
Click Finish.
The RAID Level is migrated. A confirmation message appears. You can monitor the progress of the transformation. See Background Operations Support.
