Adding Physical Drives to a Configuration

For example, if you want to migrate the RAID level of a drive group from RAID 0 to RAID 5, the Modify Drive Group wizard lets you add unconfigured physical drives to the existing configuration to enable the RAID level migration.
  1. In the Modify Drive Group window, click Add Physical Drives.

    The drives you add must have the same capacity as, or greater capacity than, the drives already in the drive group, or you cannot change the RAID level.

    The Available Unconfigured Drive window appears. It lists the drives you can add, and 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 Physical Drives.
  3. Click Finish.
    The RAID level is migrated. A confirmation message appears. You can monitor the progress of the reconstruction. See Background Operations Support.
