Adding Drives to a Configuration

For example, if you migrate the RAID level of a array from RAID 0 to RAID 5, the Modify Array wizard lets you add unconfigured drives to the existing configuration to enable the RAID level transformation.
  1. Click Add Drives in the Modify Array window.
    Note: The drives you add must have the same capacity as or greater capacity than the drives already in the array, or you cannot change the RAID level.
    The Available Unconfigured Drive window appears. It lists the drives you can add, and it states whether you must add a minimum number of drives to change the RAID level from the current level to the new RAID level.
  2. Select the available unconfigured drives and click Add Drives.
  3. Click Finish.
    The RAID level is migrated. A confirmation message appears. You can monitor the progress of the transformation. See Background Operations Support.
