•Create a volume using the added disks (see Create and Encrypt a Volume on page 28).

•Change the RAID level (see Change to a Different Flex-RAID Level on page 25).

•Switch to X-RAID (see Change from Flex-RAID to X-RAIDon page 24).

To add a protection to a Flex-RAID volume:

1.Add a disk to your ReadyNAS storage system.

For more information about how to add a disk to your system, see the hardware manual for your system, which is available at http://support.netgear.com/product/ReadyNAS-OS6.

2.Select System > Volumes.

The new disk is displayed in the enclosure graphic and is colored black.

3.Select the new disk from the enclosure graphic.

4.Click the Add Parity button next to a volume that allows or requires additional protection.

A pop-up screen appears and asks you to confirm your decision.

5.Click the Yes button.

Your data protection is increased in the background while you continue to use your storage system.
