Data on disk will be overwritten (lost) by creating the hardware raid. Consider to take an ignite backup, configure the disk and restore the backup.

Performing Hardware RAID on these disks would result in data loss..As Torsten suggested you would need to take Ignite backup, create the HW raid and then restore the image.

Alternatively you can also use the Software RAID (LVM mirroring) to configure the RAID on these disks.
