In the example below, we will change a Basic volume to a RAID 1 volume.
Before You Start:

    Make sure the status of your volume or disk group is Normal.
    When adding new hard drives to a volume or disk group, the new hard drives must be larger than the smallest hard drive in the volume or disk group.
    The status of new hard drives must be Initialized or Not Initialized.

To change the RAID type of a volume:

    Open Storage Manager.
    Go to Volume. (If you want to change the RAID type of a disk group, then go to the Disk Group tab.)
    Select the volume you wish to change and click Manage.
    When the setup wizard appears, select Change RAID type. Then click Next.
    Select the RAID type to which you want to change the volume. Click Next.
    Select which hard drive(s) to add to the existing volume. Then click Next.
    Follow the instructions of the wizard to finish. Please note existing data on the added hard drive shall be deleted.
