Netgear RN3220 – ReadyNAS 3220 2U 12 Bay Diskless Hardware Manual

The disk tray is secured in the drive bay.

If necessary, turn on your system by pressing the Power button.

If the disk that you added was not previously formatted, the system uses the disk in one of the following
ways:

In a system that uses X-RAID, the system automatically determines whether the disk is used for
protection or storage. The new disk is incorporated in the background while you continue to use your
system.

In a system that uses Flex-RAID, the disk becomes available for use. You use the local admin page
to manually configure the new disk.

For more information about X-RAID, Flex-RAID, and using the local admin page, see the ReadyNAS
OS 6.5 Software Manual, which is available at 

If your volumes use a protected RAID configuration, your system can recover from the failure of a disk.
When you replace the failed disk, the system rebuilds the volume using the new disk and no data from the
volume is lost.

Each disk tray includes a Fault LED that lights solid red when its disk fails. You can also use the local admin
page to set up email alerts that notify you when a disk fails. In addition, the local admin page provides
information about the failed disk.

For information about RAID configurations, setting up email alerts, and using the local admin page, see the
ReadyNAS OS 6.5 Software Manual, which is available at 

ReadyNAS supports hot-swap drive bays, so you do not need to power down your storage system when
replacing a disk.

If you are replacing a disk with a previously formatted disk, see the instructions in 

 on page 57.
