Additional Documentation

For detailed information about configuring, managing, and using your ReadyNAS storage system, see the ReadyNAS OS 6 Software Manual, which is av ailable at http://support.netgear.com/product/ReadyNAS-OS6.

For additional product support information, visit http://support.netgear.com/product/ReadyNAS-OS6.

Setup Location

Your ReadyNAS storage system is intended for installation in a restricted access location (dedicated equipment rooms, service closets, and the like) only.

Keep the following considerations in mind as you install your system:

• Ambient operating temperature. If the system is installed in a closed or multiunit rack assembly, the

ambient operating temperature of the rack en vironment might be greater than the ambient temper ature of the room.Therefore, consider installing the equipment in an environment compatible with the maxim um rated ambient temperature. See Defaults and Technical Specifications on page 29.

• Reduced airflow. Mount the equipment into a rack so that the amount of airflow required for safe

operation is not compromised.

• Mechanical loading. Mount the equipment into a rack so that a hazardous condition does not arise

due to uneven mechanical loading.

• Circuit overloading. Consider the equipment's connection to the power supply circuitry and the effect

that any possible ov erloading of circuits might create on overcurrent protection and pow er supply wiring. Consider equipment nameplate ratings when addressing this concern.

• Reliable grounding.This product requires reliable grounding to be maintained at all times.To ensure

this, ground the rack itself. Pay particular attention to power supply connections other than the direct connections to the branch circuit (for example, the use of power strips).

• Clearance. Leave enough clearance in front of the rack (about 25 inches) to enable you to open the

front door completely and in the back of the rack (about 30 inches) to allow for sufficient airflow and ease in servicing.

Supported Operating Systems

The ReadyNAS storage system is supported on the following systems:

• Microsoft Windows 10 (32 and 64 bit)

Disks

This chapter describes how to reformat, add, and replace disks in your ReadyNAS OS 6 storage system. For information about configuring disks on your storage system, see the ReadyNAS OS 6 Software Manual,

which is available at http://support.netgear.com/product/ReadyNAS-OS6. This chapter includes the following topics:

• Supported Disks

• Previously Formatted Disks

• Add a Disk

• Replace a Disk

Most ReadyNAS systems use disk trays.The RR2312 does not.Note

ReadyNAS OS 6

Supported Disks

Use only supported SATA hard disk drives (HDDs) or solid-state drives (SSDs) in your ReadyNAS storage system. If you use disks that are not supported, NETGEAR Technical Support will not provide assistance. For a list of supported disks, see the NETGEAR Hardware Compatibility List at

http://www.netgear.com/readynas-hcl.

Previously Formatted Disks

You can use previously formatted disks with your ReadyNAS OS 6 storage system, but you might need to reformat them or migrate a volume to the new system first.

Previously formatted disks must appear on the NETGEAR Hardware Compatibility List, which is available at http://www.netgear.com/readynas-hcl.

Reformat Previously Formatted Disks

If you want to use disks that were previously formatted for an operating system other than ReadyNAS OS 6 (for example, Windows or RAIDiator), you must reformat the disks.

If you want to use disks from another ReadyNAS OS 6 storage system, see Migrate a Volume on page 21.

If you try to use previously formatted disks in a system that does not contain any other

Note

disks, the system does not boot and ReadyCLOUD does not discover your device. If you use RAIDar to discover your device, RAIDar displays a Corrupt Root error message. If you try to use previously formatted disks in a system that already contains usable disks, the system does not reformat or use the previously formatted disks. Any data on the previously formatted disks remains intact.

The following instructions describe how to reformat previously f ormatted disks in a ReadyNAS OS 6 system. This procedure assumes that the system does not contain any other disks.

To reformat previously formatted disks with a diskless ReadyNAS OS 6 system:

1. Gracefully shut down the storage system.

For information about how to gracefully shut down your system, see Preferred Shutdown on page 16.

2. Install the disk.

For more information, see Add a Disk on page 21.

3. Reset the system to its factory default settings.

WARNING:

This process erases all data and reformats all disks into a single X-RAID volume. If you want to preserve the data on the disks, you must back up the data to an external drive before using the disks in your ReadyNAS storage system.

Disks

ReadyNAS OS 6

For information about how to reset the system to its factory default settings, see Boot Menu on page

17. The disk is reformatted and becomes available for use with your ReadyNAS OS 6 storage system.

Migrate a Volume

You can migrate a volume from one ReadyNAS OS 6 storage system to another, as long as you migrate every disk in the volume. For example, if you want to migrate a volume that contains two disks, you must add both disks to the new system. If you add only part of a volume to the new system, the system recognizes the disk as a degraded volume.

If your ReadyNAS storage system is operating with one or more disks, you can add disks while the system is running.The new system recognizes the migrated volume and its data. For more inf ormation about adding a disk while the system is running, see Add a Disk on page 21.

If no disks are installed on your ReadyNAS, perform the following procedure.

To migrate a volume to a diskless ReadyNAS OS 6 system:

1. Gracefully shut down the new (diskless) storage system.

For information about how to gracefully shut down your system, see Preferred Shutdown on page 16.

2. Remove each disk in the volume from the old system.

3. Install each disk in the volume into the new storage system.

For more information, see Add a Disk on page 21.

4. Turn on the new system by pressing the Power button.

The new system recognizes the migrated volume and its data.

Add a Disk

You can add 3.5-inch disks. If you want to add a previously formatted disk to your storage system, see the instructions in Previously

Formatted Disks on page 20.

To add a disk:

1. Determine whether you must shut down your system:

• If you are adding disks to a diskless system, gracefully shut down the system.

For information about how to gracefully shut down your system, see Preferred Shutdown on page

16.

• If your system is operating with one or more disks, you can add disks while the system is running.

You do not need to shut down the system.

2. Remove the screws securing the chassis to the rack and rails.

3. Pull the system forward from the rack until the rails lock partially extended.

Use care when pulling the system forward to keep from stressing the cables attached to the back.

4. Unscrew the two thumb screws on the front of the chassis.

13. Slide the chassis back into the rack.

14. Replace the two M5 bolts through the chassis tabs into the center of the rails.

15. 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:

• If you are adding the disk to 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.

• If you are adding the disk to a system that uses Flex-RAID, the disk becomes available f or 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 Software Manual, which is available at http://support.netgear.com/product/ReadyNAS-OS6.

Replace a Disk

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.

Disks

ReadyNAS OS 6

For information about RAID configurations, setting up email alerts, and using the local admin page, see the ReadyNAS OS 6 Software Manual, which is av ailable at http://support.netgear.com/product/ReadyNAS-OS6.

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

building.

5. Slide-mounted or rail-mounted equipment is not to be used as a shelf or a work space.

Electrical Safety Precautions

Follow basic electrical safety precautions to protect yourself from harm and the ReadyNAS from damage:

• Be aware of the locations of the Power switch on the chassis and the room's emergency power-off

switch, disconnection switch, or electrical outlet. If an electrical accident occurs, you can then quickly remove power from the system.

• Do not work alone when working with high-voltage components.

• Always disconnect pow er from the system when remo ving or installing main system components , such

as the main board or memory modules.When disconnecting power, first power down the system with the operating system and then unplug the power cords of all the power supply storage systems in the system.

• When working around exposed electrical circuits, make sure that another person who is familiar with

the power-off controls is nearby to switch off the power if necessary.

• Use only one hand when working with powered-on electrical equipment.This is to avoid making a

complete circuit, which will cause electrical shock. Use extreme caution when using metal tools, which can easily damage any electrical components or circuit boards that they come into contact with.

• Do not use mats designed to decrease static electrical discharge as protection from electrical shock.

Instead, use rubber mats that were specifically designed as electrical insulators.

• Use only power supply cords that include a grounding plug and plug them into grounded electrical

outlets.

General Safety Precautions

Follow these rules to ensure general safety:

• Keep the area around the ReadyNAS clean and free of clutter.

• See the technical specifications in this manual for details about your specific ReadyNAS stor age systems.

Defaults and Technical Specifications

ReadyNAS OS 6

• The ReadyNAS weighs approximately 82 pounds when fully loaded.When lifting the system, two people

at either end should lift slowly with their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.

• Place the chassis top cover and any system components that were removed away from the system or

on a table so that they will not accidentally be stepped on.

• While working on the system, do not wear loose clothing such as neckties and unbuttoned shirt sleeves ,

which can come into contact with electrical circuits or be pulled into a cooling fan.

• Remove any jewelry or metal objects from your body, which are excellent metal conductors that can

create short circuits and harm you if they come into contact with printed circuit boards or areas where power is present.

• Replace the on-board battery only with the same battery or an equivalent type of battery recommended

by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.

Installing the on-board battery upside down, which reverses its polarities, creates a

risk of explosion.Take care to install the battery correctly.

• Only trained service technicians can replace the self-resetting PTC (positive temperature coefficient)

fuses on the main board, using only new fuses that are the same as or equivalent to the ones being replaced. Contact Technical Support for details and support.

Rack-Mount Precautions

Follow these rack-mount precautions:

• Make sure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full

weight of the rack resting on them.

• In single-rack installations, make sure that stabiliz ers are attached to the rack. In multiple-r ack installations,

make sure that the racks are coupled together.

• Always make sure that the rack is stable before extending a component from the rack.

• Extend only one component at a time. Extending two or more simultaneously might cause the rack to

become unstable.

• Determine the placement of each component in the rack before you install the rails.

• Install the heaviest components on the bottom of the rack first, and then work up.

• Use a regulating uninterruptible power supply (UPS) to protect the ReadyNAS from power surges and

voltage spikes and to keep your system operating in case of a power failure.

• Allow any hot-plug drives and power supply modules to cool before touching them.

• Always keep the rack's front door and all panels and components on the servers closed when not

servicing them to maintain proper cooling.
