GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

GNU GENERAL PUBLIC LICENSE

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The “Program”, below, refers to any such program or work, and a “work based on the Program” means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term “modification”.) Each licensee is addressed as “you”.

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Progr having been made by running the Program). Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

am (independent of

REO 9100/9100c User Guide

2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivale sour ce code from the s ame p la ce co unts as di stri buti on of th e source code, even though third parties are not compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide i f he or she is willi ng to d ist ri bute s oft ware t hroug h any o ther system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and “any later version”, you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

nt access to copy the

REO 9100/9100c User Guide

10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Project: NDMJOB

Description: NDMPv0, represented here, is a fictitious version used to negotiate NDMP protocol version for the remainder of the session. Early, as a connection is being set up, the version of the protocol is unknown. The first messages exchanged negotiate the protocol version, and such messages are in the NDMP format. This is different than other protocols, such as ONC RPC which negotiate version by lower layers before the objective protocol becomes involved. During the negotiation, we deem the connection to be in “v0” mode. This NDMPv0 protocol specification is the subset of the NDMP protocol(s) required for the negotiation, and necessarily must remain immutable for all time.

Flow Indicator (>) Words in bold font with a greater than sign between them indicate the

Safety Notices

General Cautions

CAUTION A Caution contains information that the user needs to know to avoid

damaging or permanently deleting data or causing physical damage to the hardware or system.

WARNING A Warning contains information essential to people’s safety. It

advises users that failure to take or avoid a specific action could result in physical harm to the user or hardware.

flow of actions to accomplish a task. For example, Setup > Passwords > User indicates that you should press the Setup button, then the Passwords button, and finally the User button to accomplish a task.

CAUTION: Before touching any of the appliance components, ground yourself and

take antistatic precautions. Use an antistatic wrist strap and a grounding wire as a minimum precaution.

CAUTION: Each storage appliance must have a good electrical ground connection

through each power cord, through the building power grid to the point of origin for the building power source entry.

REO 9100/9100c User Guide Preface

CAUTION: Circuit Overloading—Consideration should be given to the connection of

the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing the concern.

CAUTION: Reliable Grounding – Reliable grounding of rack-mounted equipment

should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Installation Warnings and Notes

WARNING: To prevent personal injury and equipment damage, have someone assist you during installation. If necessary, reduce the weight of the storage appliance by removing the disk drives and PS unit.

WARNING: Mechanical Loading—Prevent instability by installing heavier items into the bottom of the equipment rack. Mounting of the equipment in a rack should be such that a hazardous condition is not achieved due to uneven loading to prevent personal injury.

CAUTION: Ensure that your equipment rack is placed in a dust-free, well ventilated

area close to a UPS. Leave enough room behind the rack for servicing and to allow for sufficient airflow.

CAUTION: Elevated Operating Ambient Temperature—When installed in a closed or

multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer's maximum recommended ambient (TMRA).

CHAPTER

Overview

Introduction and Requirements

The Overland REO 9100 Disk-Based Backup and Recovery Appliance with Protection OS™ embeds data protection intelligence, and delivers a core set of volume and device virtualization, management, and connectivity features. It supports both iSCSI and Fibre Channel (FC) connectivity.

The REO 9100 uses a Web-based interface and can be easily configured as a virtual tape library (VTL) and/or any mix of standalone virtual tape drives, Dynamic Virtual Tape (DVT) drives, or virtual disks. Using DVT, users can create virtual tape cartridges that automatically expand or shrink as needed to match the exact capacity requirements of the backup operation.

The REO 9100 comes in two versions: the basic appliance with optional software compression (REO 9100) or the always-on hardware compression version (REO 9100c). The REO 9100c comes with special data compression hardware that offers high performance compression and decompression capabilities for use with any virtual tape device. It provides 2:1 or better compression without sacrificing performance.

NOTE: Due to the availability of the superior hardware compression feature, software

compression is not supported on the REO 9100c. Also, hardware compression is only available for virtual tape drives; it is not an available option for disk targets.

By default, compression is enabled and is available for all virtual tape devices on the REO 9100c. The REO 9100c also implements in-band host application enable or disable requests, and monitors the compression status for the virtual tape devices.

NOTE: Hardware compression settings cannot be changed manually.

Reviewing Pre-Installation Requirements

Before attempting to operate the REO 9100 with your backup servers, verify that your network meets the minimum requirements specified in the following sections.

REO 9100/9100c User Guide Introduction and Requirements

Network

For best results, Overland strongly recommends that you use a dedicated GbE network to share the storage resources on the REO 9100 among multiple backup servers.

To ensure optimum performance, always use the appropriate patch cables to connect the REO 9100 to the backup-server storage network. To select the appropriate cables, use the following guidelines:

• If you intend to use GbE, you must use Category 5e (or better) cables for

GbE connections. You can use either straight-through or cross-over cables.

• If you intend to connect the REO 9100 to a 100BaseT or faster network, use

Category 5 (or better) shielded cables.

• The maximum length of cable for any Ethernet-based network connection is

328 feet (100 meters).

NOTE: For smaller environments, you can attach the REO 9100 directly to a single

application or backup server by using standard Category 5e cables without the use of a switch.

Initiators

Browser

Initiators are required to communicate with the REO 9100 targets (devices). Each backup server that will interface with the REO 9100 must be equipped with a software- or hardware-based initiator. The REO 9100 supports any computing platform with an available iSCSI initiator, either in software or using an iSCSI HBA (it must comply with iSCSI draft 20, version 1.0).

The REO 9100 GUI is a Web-enabled program that requires the use of cookies, Java applets, and Java scripts. Make sure that the Web browser you use is configured to allow these items.

CHAPTER

REO 9100/9100c User Guide Hardware Setup

Preparing the Array and Installation Area

WARNING: Due to the weight of each rack-mounted unit when it is fully extended, you should install units in the rack from the bottom up. Extending a unit that has empty spaces beneath it might cause the rack to tip forward or might result in personal injury. Overland recommends that at least two people support and slide the unit in the rack.

Unpacking the REO 9100

Because of its weight when loaded with disk drives, the Overland Storage REO 9100 appliance ships in two boxes.

Box one contains:

• REO chassis

• Power cords

• Rack-mount slide rail kit and hardware

• REO 9100 Documentation CD

• REO 9100 Quick Start Guide

Box two contains:

• 24 disk carriers, some or all with disk drives installed

NOTE: Depending on which version of the product that you purchased, either 12 or

24 of the carriers come with drives installed.

IMPORTANT: Before unpacking the unit, ensure that the area is free from conditions that cause electrostatic discharge (ESD). Discharge static electricity from your body

by touching a known grounded surface. Also, avoid touching pins, leads, or circuitry.

Preparing the Installation Area

Review the following guidelines before positioning the appliance physically within your network.

• Make sure there is unrestricted air flow around the unit and through the

vents in the sides and rear of the case.

• Route external cables so that they can be connected easily without blocking

air vents or impeding air flow.

• Protect the appliance from extreme temperature and humidity. Overland

recommends that you install the unit in a clean, air-conditioned environment where water and moisture cannot enter the case of the appliance. Keep the air as free from dust as possible.

• Protect the appliance from physical shock and vibration.

• Make sure that the inlet air temperature within the rack remains below the

specified limit of 95°F (35°C).

• Keep the appliance and cabling away from sources of electrical noise since

electromagnetic fields can interfere with the signals on copper cabling and introduce errors, therefore slowing down the network.

Mounting the Appliance in a Rack

Your REO 9100 appliance comes with a set of slide rails for mounting the chassis in the 19-inch rack. The REO unit has a 5U form factor. The inner rail segments are already attached to the chassis.

Installing the Rail Kit

Use these steps to install the rail kit in a square-holed RETMA rack (Figure 2-2):

NOTE: For a threaded-hole rack, omit the washers.

Figure 2-2: Outer Rail & Bracket Assembly and Positioning

1. Identify and mark the screw holes on the front and rear vertical rails of the

rack where the slide rails will be installed.

2. Loosely install rear bracket inside the rear vertical rack rail (Figure 2-3)

using two sets of screws, washers, and nuts (or bar nut) supplied.

Figure 2-3: Attached the Bracket to the Rack

3. For a standard RETMA rack, loosely attach two screws through the 9th

holes from the rear of the bracket (

6. Verify that the rail assemblies are installed properly and tighten the screws

holding the rail assembly to the rack.

7. Tighten the screws that secure the bracket to the outer/middle rail

assembly.

8. Repeat Steps 2–7 for the other rail assembly.

Inserting the Appliance

1. Pull out the middle slides from the front of the rack so that they lock in the

extended position (click).

REO 9100/9100c User Guide Hardware Setup

2. Using a mechanical lifter or two people, lift the appliance to its install height

and engage the inner slides mounted on the chassis with the middle slides protruding from the rack.

3. Slide the appliance in until it stops.

4. Simultaneously press both lock buttons on the inner rails and slide the

appliance in until it stops again.

5. Press the same lock buttons again and slide the appliance all the way into

the rack.

6. Slide the appliance in and out several times, ensuring that the inner and

outer slide locks engage and the

chassis does not bind against the slides. If

binding occurs:

a. Remove the appliance.

a. Loosen the screws that secure the slides to the front and the rear rails of

the rack.

b. Readjust the slide positioning as needed and retighten the screws.

c. Reinsert the appliance and verify that it does not bind.

7. Slide the appliance all the way into the rack and secure the appliance

flanges with screws (left and right side) to the rack.

Reinstalling Drive Carrier Assemblies

IMPORTANT: To maintain proper airflow and cooling, a disk drive or a blank drive carrier must be installed in every slot.

The disk drive assemblies (disks mounted in carriers) are packaged separately, which allows you to insert them into the array chassis after you have installed the chassis in the rack. Each disk carrier contains a label that identifies the slot into which you must insert it.

IMPORTANT: Do not remove the drives from the drive carriers. The RAID array is preconfigured so failure to install the disks in the corresponding slots may result in

the need to create a new configuration.

To install disk carriers in chassis

1. Insert the first disk carrier into the appropriate slot in the chassis.

2. With the lever in the open position, push firmly on both sides of the carrier

to ensure that the latch and connector are fully seated.

3. Press the lever in until it clicks into the locked position.

This draws the carrier fully into the slot and seats it properly inside the chassis.

4. Repeat these steps for each disk carrier.

Attaching Cables

All cabling and power connections are located on the rear panel of your REO appliance (Figure 2-7). Connections are available for Ethernet, USB, and serial cabling. All unit cooling exhaust is handled through the rear panel.

Figure 2-7. REO 9100 Rear Panel Connections

REO 9100/9100c User Guide Hardware Setup

Once the unit is secured in the rack and the disk drives installed, you are ready to attach the cables that connect the REO appliance to your host system and power source.

1. Plug the network connection into the Ethernet port.

Using a Category 5e (or better) cable, connect Data Port 1 on the appliance to the management LAN.

2. Connect any other cables to the appropriate plugs as shown (Figure 2-7).

3. Attach the four power cords to the AC Power sockets on the REO back

panel, but do not connect the cords to any AC power sources yet.

Powering up the unit is covered in the next chapter.

Connecting a UPS

IMPORTANT: Overland recommends connecting your REO 9100 to an Uninterruptible Power Supply (UPS).

NOTE: For more information on using a UPS, refer to “Backup Power” on page 3-4.

1. Make sure the REO 9100 is powered down and unplug the AC cords from the

main AC power source.

2. Connect the USB cable from the UPS to the USB port on the REO 9100 back

panel.

3. Plug the AC power cords from the REO 9100 into the AC sockets on the UPS.

4. Plug the AC power cord from the UPS into a main AC power source.

CHAPTER

Powering Up the Appliance

The main steps involved in enabling power to the REO 9100 include:

1. Making sure that the disks are correctly inserted in the appliance.

2. Connecting the power cords to a power source and enabling power.

3. Shutting down the appliance.

4. Using an Uninterruptible Power Supply (UPS).

Verifying Insertion of Disks

Because your appliance is configured with two RAID 5 with Hot Spare arrays, it is important that the disks are inserted in the correct slots in the appliance.

all of the same capacity. The drives in one unit can be a different capacity than those in the other units as long as all the drives in that unit are the same size.

Make sure that the disks are seated correctly to prevent an error state during the power-on procedure. For more information, see

Assemblies” on page 2-5.

Enabling Power

situation is resolved. Overland recommends that you use separate power mains for the power sources.

Power problems can be the cause of serious failures and downtime on your network. Ensure that the power input to your system is clean and free from sags and surges to avoid unforeseen network outages. Overland strongly recommends that you install power conditioning and an adequately rated uninterruptible power supply (UPS), especially in areas prone to blackouts, power dips, and electrical storms.

IMPORTANT: The REO 9100 head unit must be populated with drives that are all of the same capacity. Also, expansion units must be fully populated with drives that are

The REO 9100 is intended to be grounded. Ensure it is connected to earth ground during normal use.

Power Supplies

Each of the four power supply modules contain:

• A socket for an AC line cord.

• A two-color LED for indicating the status of the power supply.

• When all outputs are available, the LED becomes green.

• If the power supply fails, the LED becomes red.

• A latch with a thumbscrew for releasing the power supply.

• A handle for pulling the power supply out of the appliance.

• A pair of fans to prevent overheating.

• A feature that verifies the following (if not detected, an alarm signal

sounds):

• All output voltages V1 to V5 are within regulation.

• The fans are operating normally.

• The internal temperature of the power supply is normal.

An Alarm Reset switch (red push button) is located on the back panel, in the location shown in

Figure 3-1.

Figure 3-1: Enabling Power to REO Appliance

CAUTION: To power on a REO system with an expansion unit, refer to Chapter 8,

“Expanding Capacity.” If you do not complete these steps in this order, the

appliance might start in an error state.

REO 9100/9100c User Guide Powering Up the Appliance

Power Button

To power up the appliance:

1. Plug each of the power cords into a separate AC power source.

IMPORTANT: If power is automatically enabled when you attach the cords to

an AC power source, shut down the appliance before continuing with the setup process. For details on shutting down an appliance, see “Shutting Down the

Appliance” on page 3-4

2. To power up the REO 9100, press and hold the power button for about 1

second, which starts the power-up sequence.

The power switch is located in the top area of the front panel above the third column of disks. The power switch is a momentary contact device that needs to be held to begin the power-up sequence.

Figure 3-2: Power Button Location

After you turn the power on, the REO 9100 performs a power-on self-test (POST) process. Following successful completion of the POST, which takes several minutes, you should hear 3 beep tones spaced about 1 second apart.

If you are unable to hear the tones in your physical environment, wait approximately five minutes before continuing.

IMPORTANT: On startup, the appliance might reach an error state and begin

an endless loop of alerts. The pattern (2 beeps separated by a 1-second delay) repeats every 4 seconds. If this occurs, turn the appliance off and then back on. For more information, see “Perpetual Loop of Audible Alerts on the

Appliance” on page A-12

3. After you hear the POST completion beep tones, proceed to the configuration

steps outlined in the next chapter,

“Configuring the REO Software” on

page 4-1.

IMPORTANT: You must leave the appliance ON while completing the

configuration process for your application and backup servers.

REO 9100/9100c User Guide Powering Up the Appliance

Shutting Down the Appliance

IMPORTANT: To ensure preservation of data on the REO 9100, you should not turn off the appliance using the power button. Always use the Shut Down option located

in the REO 9100 GUI.

NOTE: If you are setting up a new appliance and you did not complete the steps in the

proper order or power was automatically enabled, you might not have access to the Shut Down option in the REO 9100 GUI.

To shut down the appliance via the GUI:

1. Verify that no backup/restore jobs are running.

2. In the REO 9100 GUI, under System Menu, click Maintenance.

3. On the Maintenance page, under Shut Down/Restart, click Shut Down.

4. When the confirmation message appears, click OK.

To shut down the appliance without GUI access:

1. Press and release the power button on the front of the appliance quickly

(1 second or less) to initiate a graceful software-system shutdown process.

2. Wait up to 1 minute to see if the appliance responds.

3. If the appliance does not shut down after the first attempt, repeat

Backup Power

In order to protect your data from loss due to sudden power interruption, your REO 9100 supports the use of an external UPS. The REO 9100 monitors the UPS via the USB port (reporting the charge level on the System Summary page). When the REO 9100 senses a low UPS power condition, it initiates a graceful shutdown that completes before the UPS runs out of battery power.

The LED for power will turn off after the shutdown process is finished.

Steps 1–2 a second time.

CAUTION: Pressing and holding the power button for 4 seconds or more causes an

immediate hardware-shutdown that might result in the loss of data on the appliance if there are any active read-, write-, or management-operations. Whenever possible, turn off the appliance using the REO 9100 GUI or the graceful shutdown method described earlier. If you must use the immediate hardwareshutdown method, make sure that you first stop all host- and management-serverrelated activity.

REO 9100/9100c User Guide Powering Up the Appliance

UPS Power Monitoring

When the REO appliance detects that it is connected to a UPS, it displays the UPS Information (

• When the REO is receiving power from the main AC source, the indicator

bar is green. A complete green bar and 100% indication mean that the UPS battery is fully charged.

• When the main AC power is interrupted and the REO is powered by the

UPS, the indicator bar turns red. The red bar and the numeric indication grow smaller as the UPS battery charge goes down.

Figure 3-3) at the bottom of the System Summary page.

Figure 3-3: System Summary Page UPS Information

• When the primary AC power is restored, the indicator bar turns green. The

green bar and the numeric indication grow toward 100% as the UPS battery charges itself up.

Behavior When Connected to UPS

A REO 9100 with a UPS works normally as long as the main AC power is supplied. When the main AC power is interrupted and the REO 9100 detects battery power, it initiates a graceful shutdown in such a way as to be completed before the battery power runs out.

Once initiated, the shutdown continues to completion, even if the AC power has been restored. Upon completion of the shutdown, and when the AC power has been restored, the REO 9100 does not restart automatically. Use the Power button on the front panel to restart the REO 9100.
