S-9

SAFETY SUMMARY (Continued)
 Pay attention not to apply shock to the replacing HDD and the replaced HDD
during work, whether installed or not installed on the Equipment. When notinstalled, place each HDD on a shock-absorbing material such as antistaticcushion, even temporarily. Direct placement on a hard surface such as desktop
may cause damage, data corruption, or shortening of service life due to shock.
 Insert the HDD firmly and precisely. A loose contact or a missing screw willcause a failure.
 While the HDD is powered, never attempt to unscrew and hot-plug the HDD.
Otherwise, a machine failure or HDD failure may result.
 The HDD detachment/attachment must be limited to the least, e.g., replacementin the event of a failure. Frequent detachment/attachment may cause damage tothe Equipment.
 On D Model, also observe the following: Do not altogether replace the two HDDs in RAID1 configuration.
 Since each D Model has its own RAID1 configuration information (e.g.,
serial number), you cannot swap HDDs even between D Models. If you dare,
the stored data in the newly installed HDD will be erased with automatic
RAID1 rebuilding process due to inconsistency of the RAID1 configuration
information. If you own multiple D Models, manage use and inventory of
HDDs so that they are not inadvertently mixed.
 Never remove the HDD if the corresponding HDD status lamp is off.
Otherwise, the stored data will be destroyed.
 When you replace an HDD while the Equipment power is on, first stop thepower supply to the target HDD by placing the HDD into OFFLINE state in
the “Hardware status” window. Never attempt HDD replacement before thiswindow is ready (e.g., immediately after the OS startup). Otherwise, amachine failure or HDD failure may result.
 When you intend to move the Equipment, first shut down the OS, thendisconnect the power cord plug from the outlet, and wait at least one minute.
Otherwise, failure of hardware such as HDD may result.
 When transporting or carrying the Equipment, repack it using the packing
materials that came with it and are not broken or dented. Transporting or
carrying the Equipment either packed by other packing materials or repacked bybroken or dented packing materials may damage the Equipment.
 By the characteristics of rush current suppression circuit on this Equipment, alarger rush current than usual may flow when power is supplied before thepower supply unit is naturally cooled after the last power-off. To avoid possible
adverse effects on the connected electronic devices such as fuse-free breakers
and on the service life of this Equipment, wait at least one minute of the last
power-off before you supply power to the Equipment.
(See Section 8.2 on page 8-2.)

S-10

SAFETY SUMMARY (Continued)
 Although this Equipment featuring RAID1 is more reliable than general systems,
it is still prone to the loss of data in the HDDs. Not only a machine failure but
also an unexpected power failure or an operation error may cause data to be lostfor good. To prevent such loss of data, implement scheduled data backup in
daily operation. Also, protect the power source from undesirable interruptions
by such means as UPS.
 This Equipment is evaluated based on the specific HDD models authorized by
the Manufacturer. Replace only with specific HDD models authorized by the
Manufacturer. Otherwise, the existing data in the HDD may be lost. Also,
always observe the recommended replacement interval for HDDs (Section 5.3,
“Replacement of Consumable Parts”).
 Since each Equipment has its own RAID1 configuration information (e.g., serial
number), you cannot swap HDDs even between two units of this Equipment. If
you dare, the stored data in the newly installed HDD will be erased with
automatic RAID1 rebuilding process due to inconsistency of the RAID1
configuration information. If you own multiple units of this Equipment, manage
use and inventory of HDDs so that they are not inadvertently mixed.
 Each Equipment contains uniquely assigned HDD serial numbers in its own
RAID1 configuration information. Accordingly, if you create a copy of theexisting HDD without using the RAID1 rebuilding process, the copy will berecognized new and invalid. This new HDD, if installed in the drive bay, will
not start up the Equipment.
 Maintenance of a disk array system requires in-depth knowledge. In case of an
operation error, data in the HDD may be lost.
(See Section 9.1 on page 9-1.)
 When you newly build a RAID1 system on the Equipment, the setup process
writes the RAID1 configuration information, which only applies to this specificserial numbered Equipment. Since these HDDs containing such RAID1
configuration information are not usable on any other Equipment with a different
serial number, manage handling and inventory of HDDs so that they are notinadvertently mixed if you own multiple units of this Equipment. Should awrong HDD be installed, the Equipment may not start up or you may lose datastored in the HDD due to inconsistency of the RAID1 configuration information.
 When you newly build a RAID1 system on the Equipment, prepare two newunits of specific HDD models authorized by the Manufacturer. If you use an
unauthorized HDD, you may lose data stored in the HDD.
(See Section 9.2 on page 9-2.)

S-11

SAFETY SUMMARY (Continued)
 Never remove the HDD if the corresponding HDD status lamp is off.
Otherwise, the stored data will be destroyed.
 To prevent damage due to static electricity discharge, wear cotton gloves when
you replace an HDD. Otherwise, the stored data may be destroyed.
 Before you ensure “Not Connected” status in the “Hardware status” window,
never mount a new HDD.
 Insert a new HDD firmly and precisely. A loose contact or a missing screw willcause a failure.
 Pay attention not to apply shock to the replacing HDD and the replaced HDD
during work, whether installed or not installed on the Equipment. Otherwise, afailure may result.
 Never shut down the OS or perform the HDD detachment/attachment work
before the RAID1 rebuilding process is complete. Otherwise, the stored data in
the HDD may be lost or a failure may result.
(See Section 9.4 on page 9-5.)
 To prevent damage due to static electricity discharge, wear cotton gloves when
you replace an HDD. Otherwise, the stored data may be destroyed.
 Observe the work order and follow the given instructions. Otherwise, the stored
data may be lost.
(See Section 9.5 on page 9-11.)(See Section 9.5 on page 9-12.)
 Do not replace with an HDD previously used in any RAID level. Otherwise, theEquipment may not start up or you may lose data stored in the HDD due toinconsistency of the RAID1 configuration information or similar cause.
 Selecting a wrong HDD as the target will erase the data stored in the HDD.
Fully ensure the drive bay number for the target HDD on the Equipment at theuser’s responsibility.
 Do not altogether replace the two HDDs in RAID1 configuration.
 To prevent damage due to static electricity discharge, wear cotton gloves when
you replace an HDD. Otherwise, the stored data may be destroyed.
 When you replace an HDD while the Equipment power is on, first stop thepower supply to the target HDD by placing the HDD into OFFLINE state in the“Hardware status” window. Never attempt HDD replacement before thiswindow is ready (e.g., immediately after the OS startup). Otherwise, a machine
failure or HDD failure may result.
(See Section 9.5 on page 9-13.)

S-12

SAFETY SUMMARY (Continued)
 The Equipment features RAID1 and is highly reliable compared to a system witha conventional configuration. Nonetheless, the data stored on the HDDs may belost depending on the type of the failure. In addition to equipment failure data
can also be lost by power failure and human mistakes during operation. Shouldsuch situation occur, the data cannot be recovered. In order to prevent data loss,
make it a routine to save your data and establish a systematic way of backup. In
addition, increase the reliability of power supply by, for example, using a UPS.
 The Equipment is evaluated under the assumption that the HDD models
specified by HITACHI are used. When you replace an HDD, use the HDD
models specified by HITACHI. Otherwise, the data stored in the HDDs may belost. Stick to the recommended replacement cycle when you replace an HDD.
(See Section 5.3, “Replacement of Consumable Parts”.)
 The Equipment manages the unique serial number of each HDD (each HDD has
a different serial number) as part of RAID1 configuration information.
Therefore, if you copy the contents of an HDD to another HDD without using
the rebuild function of the software RAID1 construction utility, the HDD withthe copied contents is recognized as an invalid medium. Even if you mount the
HDD to a drive bay, the Equipment will not start.
 Maintenance of a disk array system requires a high level of expertise. Should
any mistakes be made during the maintenance work, data stored in the HDDs
may be lost.
(See Section 10.1 on page 10-1.)
 When you build software RAID1 from scratch, the unique serial number of each
HDD (each HDD has a different serial number) is stored in the HDDs as part of
RAID1 configuration information. If you use multiple sets of Equipment, pay
attention when you handle and store the HDDs so that the HDDs are not mixed
up. Otherwise, RAID1 configuration information mismatch occurs, and theEquipment may not start up, and the data in the HDDs may be lost.
 When you build software RAID1 from scratch, prepare two new HDDs selectedfrom the models specified and tested by HITACHI. Otherwise, the data stored in
the HDDs may be lost.
(See Section 10.2 on page 10-3.)

S-13

SAFETY SUMMARY (Continued)
 Wear cotton gloves when replacing an HDD in order to prevent failure causedby static electricity. Otherwise, the data in the HDDs may be corrupted.
(See Section 10.4 on page 10-9.)(See Section 10.5 on page 10-16.)(See Section 10.5 on page 10-18.)
 Mount an HDD steadily. Loose contact and missing screws may result in failure.
 Do not shake the installing HDD and the already mounted HDDs while
replacing an HDD. If you do so, the device may fail.
 When you use the software RAID1 construction utility, disconnect all theexternal storage devices connected to the Equipment beforehand. Otherwise, theEquipment may not start up, or the data in the HDDs may be lost.
(See Section 10.4 on page 10-9.)(See Section 10.4 on page 10-12.)(See Section 10.6 on page 10-23.)
 Until rebuild is complete, avoid shutting off the power for the Equipment or
attaching and detaching HDDs. Otherwise, the data in the HDDs may be lost or
failure may result.
(See Section 10.4 on page 10-9.)(See Section 10.4 on page 10-12.)
 Do not use an HDD previously used for software RAID1 in place of a new
HDD. Otherwise, the Equipment may not start up or the data in the HDDs may
be lost because of RAID1 configuration information mismatch or other reasons.
(See Section 10.5 on page 10-16.)(See Section 10.5 on page 10-18.)(See Section 10.5 on page 10-20.)
 Do not create a backup HDD by mounting a new HDD and then rebuilding
RAID1. The RAID1 configuration information stored in each HDD is updated
after RAID1 is rebuilt. Therefore, even if the previous HDD is reinstalled after
the rebuild is complete, the Equipment may not start up or the data in the HDDs
may be lost due to RAID1 configuration information mismatch or other reasons.
(See Section 10.5 on page 10-16.)
 During the work, make sure you follow the correct procedure. Should any
mistakes be made, the data stored in the HDDs may be lost.
(See Section 10.5 on page 10-16.)(See Section 10.5 on page 10-18.)(See Section 10.5 on page 10-20.)

S-14

SAFETY SUMMARY (Continued)
 Do not use an HDD previously used for software RAID1 in place of a new HDD
for replacement. Otherwise, the Equipment may not start up or the data in the
HDDs may be lost because of RAID1 configuration information mismatch orother reasons.
 If you pick up a wrong HDD when selecting the HDD to be replaced, the data in
the HDDs will be lost. Make sure the drive bay number of the HDD to be
replaced is correct, and replace the HDD at your own risk.
 When software RAID1 is used, you cannot replace an HDD while the power ison. When you replace an HDD, make sure the power is off.
(See Section 10.5 on page 10-20.)
 If you manually select the direction of rebuild during a rebuild process, makesure you select the right direction. Otherwise, the data stored in the HDDs may
be lost.
 Until rebuild is complete, avoid shutting off the power for the Equipment or
attaching and detaching HDDs. Otherwise, the data may be corrupted or failure
may result.
 If read or write error occurred during rebuild, it may take about one minute after
an error message is displayed until next input is allowed.

CHAPTER 10 SOFTWARE RAID1NOTICEA machine error, an unexpected power failure, or an operation error on the
Equipment may cause files to be lost permanently. To prevent such loss of data,
implement scheduled backup in daily operation.
Note for storage capacity calculations: Memory capacities and requirements, file sizes and storage requirements, etc. must be
calculated according to the formula 2n. The following examples show the results of suchcalculations by 2n (to the right of the equals signs):
1KB (kilobyte) = 1024 bytes
1MB (megabyte) = 1,048,576 bytes
1GB (gigabyte) = 1,073,741,824 bytes
 As for disk capacities, they must be calculated using the formula 10n. Listed below are theresults of calculating the above example capacities using 10n in place of 2n:
1KB (kilobyte) = 1000 bytes
1MB (megabyte) = 10002 bytes
1GB (gigabyte) = 10003 bytes
 This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment.

Hardware Connection

NOTICEBe sure to route power cords away from interface cables, as well as frompower cords and interface cables of any third-party devices such as PCs.
Otherwise, a machine failure or malfunction may result.
Before connecting or disconnecting an interface cable, shut down the OSboth on the Equipment and on the target device, as well as disconnect boththe Equipment power supply cord from the outlet and the power supply cordof the target device from the outlet. Otherwise, a machine failure due to ashort circuit may result.
If an interface cable gets disconnected while the Equipment is powered, first
shut down the OS and then disconnect the Equipment power supply cordfrom the outlet. Sudden power disconnection without shutting down the OS
may corrupt file.
If there is a cable for external contact point, ensure that it is connected to the
EXT (external control). Because a maximum voltage of 40 V dc may be
applied to this cable through the relay load, erroneous connection of thiscable to a wrong connector may cause a failure.
< NOTE > Procure a power cord with a 2-pole 3-wire plug with ground for the Equipment as
defined in Section 1.4, “Power supply cord”. Fully insert the plug of the procured
power cord into a suitable AC mains power outlet as illustrated in Figure 1-5.
 The Equipment ships with an optional cable clamp to fix the power cord to the chassis.
Attach this cable clamp on an as necessary basis.
After connecting the display unit, the keyboard, and the mouse to the Equipment, insert thepower cord plug into the outlet as illustrated in Figure 1-5. For cable lengths, see

3. OPERATION

3.3

Stopping the Equipment
Before stopping the Equipment, confirm that there are no users using the Equipment andthere are no programs running in the background. Then, perform the following operation,
which is called shutdown.
 Stop the application programs.
 Stop the OS.
The method of stopping the application programs differs depending on the software. Referto the manual of the relevant software.
How to stop the OS—Windows® XP Professional:
To stop the OS, click Start menu in the lower left corner of the screen display, and click
Turn off computer in the menu. In the “Turn off computer” dialog box opened, click
Turn Off icon. This automatically shuts down the OS and turns off the primary power,
thus leaving the Equipment only supplied with the auxiliary power. At this point the
STATUS lamp turns off and the DRIVE/STBY (Drive Access/Standby) lamp turns on.
How to stop the OS—Windows® 7 Professional:
To stop the OS, click Start menu in the lower left corner of the screen display, and click
Shut Down button in the menu. This automatically shuts down the OS and turns off the
primary power, thus leaving the Equipment only supplied with the auxiliary power. At thispoint the STATUS lamp turns off and the DRIVE/STBY (Drive Access/Standby) lamp
turns on.
When either of the above-mentioned normal power-off operation is unavailable (when the
shutdown request is somehow rejected, e.g., because of a system lock-up), keep pressing
the Power switch in the lower left of the Equipment front panel for four seconds or longer.
Then, the primary power turns off and only the auxiliary power remains supplied. Thismethod, however, disables next power-on over the LAN and hence should only be used inan emergency. (See Section 3.7, “Power Control over LAN”.)

Emergency Power-off

WARNING
In case of smoke or nasty smell, disconnect the power cord plug from the outlet
and contact your distributor or customer engineer. Using the faulty Equipment
without repair may lead to an electric shock or fire.

NOTICE

If an emergency power-off (abrupt disconnection of power cord plug from theoutlet or turning off of mains power breaker without shutting down the OS) is
done, reloading of certain system programs may be necessitated because
the journal information is lost. For this reason, never execute emergency
power-off except when power must be disconnected urgently because of
malfunction.
If power is disconnected at the source, the Equipment may not be recovered
automatically.
In a situation where the Equipment power has to be disconnected urgently or in thefollowing emergency cases, disconnect power at the source: When the Equipment itself seems abnormal (e.g., when a nasty smell occurs);
 When the Equipment cannot be stopped due to anomaly in the Equipment; When the Equipment automatically shuts down and turns off the primary power toremain on auxiliary power only, because the protecting mechanism has detected fanstop or abnormal temperature.
 Before the OS startup, the Equipment checks out for fan stop at setting up BIOS and,if such status is detected, automatically turns off the primary power.
 After the OS startup, the Equipment automatically shuts down the OS and turns off
the primary power.

3. OPERATION

3.7 Power Control over LAN
You can turn on the Equipment remotely over LAN (so-called “Wake-On-LAN™”
abbreviated to WOL). This section explains how to use such capability with the following
definition of the term “power ON”:
“Power ON” means an action to activate the Equipment in the standby status bypressing the Power switch in the front panel or transmitting the Magic Packet™ frameon the LAN interface.
To use WOL, first enable it according to the procedure in Subsection 3.7.1, “How to
enable WOL” and then perform the procedure in Subsection 3.7.2, “How to perform power
ON over LAN”. For details of the Magic Packet™ frame, see Subsection 3.7.3, “Magic
Packet™ frame format”. (Even if you don’t enable WOL, you might be able to use WOL.
But when you want to use WOL certainly, you must follow the procedure in 3.7.1, “Howto enable WOL”.)
3.7.1 How to enable WOL
By following the procedure below, you can set up WOL. (The display image assumes
Windows® XP but it is similar under Windows® 7.)
1.

Do steps 1 through 4 in Subsection 3.10.3, “How to set up link speed and duplex
mode”.

2.

Click Power Management tab and check Wake On Magic Packet from power off statecheckbox in Wake on LAN section.

3.

Click OK button. Then, restart the Equipment to cause the new setting to take effect.

3-7

3. OPERATION

3.7.2 How to perform power ON over LAN
In order to make use of WOL, the Drive Access/Standby (DRIVE/STBY) lamp must be lit(on). In addition, to keep WOL effective, the Equipment must always be placed in thestandby status by the shutdown operation. Once the standby status is entered by pressing
the Power switch for four seconds or longer, WOL will not take effect. If you entered thestandby status by pressing the Power switch for four seconds or longer, power ON the
Equipment by pressing the Power switch and then place the Equipment in the standby
status by performing the shutdown operation.
The built-in LAN interface in the Equipment complies with WfM 2.0 (Note 1) andsupports Magic Packet™ technology (Note 2). Based on this technology, receipt of a
specific information packet called “Magic Packet™ frame” arriving at the built-in LAN
interface performs power ON of the Equipment. Since no program to transmit the Magic
Packet™ frame is attached to the Equipment, procure commercially available program fortransmitting the Magic Packet™ frame.
Note 1: Wired for Management (WfM) is the hardware specifications guideline proposed by Intel
Corporation for managing internetworked PCs.
Note 2: Magic Packet™ technology is the technology developed by AMD Corporation for remotely waking
up internetworked computers.

Specifically, follow the steps below to perform power ON of the Equipment over LAN.
1.

Connect the power supply to the Equipment by connecting the input power cord to theoutlet. Ensure that the Drive Access/Standby (DRIVE/STBY) lamp turns on and stays
lit.

2.

Transmit the Magic Packet™ frame to the built-in LAN interface of the Equipment.
Ensure power ON of the Equipment when the built-in LAN interface receives the
Magic Packet™ frame.

< NOTE > Be sure to transmit the Magic Packet™ frame to the built-in LAN interface of theEquipment. See Section 2.1, “External Views of Operator Access Areas” for thephysical connection. WOL does not take effect if the Magic Packet frame is received
on an optional Ether adapter.
 Certain status of the network may cause the Magic Packet™ frame to be lost. Hence,
implement proper measures so that the Magic Packet™ frame surely arrives despite
such status when the Magic Packet™ frame is lost.

3-8

3. OPERATION

3.7.3 Magic Packet™ frame format
The format of the Magic Packet™ frame is illustrated below. The Magic Packet™ frame
must meet the basic requirements of the LAN being used, such as source address,
destination address (recipient’s MAC address or multicast address including broadcast
address), and CRC. The data sequence in the Magic Packet™ frame is formed byrepeating the MAC address of the node 16 times. This sequence may be positioned at any
place in the packet as long as it is immediately preceded by the synchronization stream
defined as 6-byte 0xFF. If the MAC address of the node matches that of the target PC
subject to main power control, the PC also receives a broadcast frame.

Synchronization stream (6-byte 0xFF)< NOTE >Possible error due to timing of Magic Packet™ frame transmission:
Implement proper measures so that the Magic Packet™ frame transmission always takes
place while the primary power of the Equipment is off. If the transmission of Magic

3.10 Notes on LAN Interfaces
3.10.1 Requirements for twisted pair Ethernet cable
The twisted pair Ethernet cable for connection to the network must comply with thefollowing specifications. No operation with any other cable type, e.g., category 5 or STP(shielded twisted pair), will be guaranteed.
LAN cable specifications: Category 5e or 6 of UTP (unshielded twisted pair)3.10.2 Autonegotiation for link speed and duplex mode
Each LAN interface is equipped with the autonegotiation function that automaticallydetects and adapts to the link speed and duplex mode of the connected hub. Have thisautonegotiation function enabled in normal use. (Autonegotiation is required for use with
the WOL function. If “Auto-negotiate 1000Mbps” is selected for the link speed andduplex mode, the WOL function becomes unusable.)
Certain combinations with connected hubs may cause the autonegotiation function to failand adversely affect communications with other devices. When the autonegotiation
function does not operate properly, set up the LAN interface as shown below.

3.10.5 Possible solutions to unstable 1000Mbps links
Certain combinations with connected hubs may cause 1000Mbps links to go unstable.
When you plan to use networks at a 1000Mbps speed, it is required that you verify
connection with the target hub in advance.
When the 1000Mbps link goes unstable, one of the following actions may recover thestability of the link:• Use an appropriate LAN cable with the length of 20 m or longer to less than 100 m.
(Be sure to use a UTP cable of category 5e or higher.)• Change the value of Gigabit Master Slave Mode to Force Master Mode (onlyeffective with the link speed setting of 1000Mbps).
Steps to perform the latter action are shown below. Should such action with yourconnected hub cause 1000Mbps link to be lost, however, restore the setting to Auto
Detect.
(1) Steps for Windows® XP

3. OPERATION

3.10.6 Precautions for use of multiple optional LAN adapters installed in addition
In an environment where multiple optional LAN adapters are installed in addition, there
may be cases when the expected performance is not reached on each LAN adapter due tofrequent interrupt requests from each LAN adapter or an excessive amount of data to beprocessed. (Interrupt requests from LAN adapters require high CPU load relative to theamount of data to be processed. When multiple LAN adapters are installed and used, it
requires a very long time for the CPU to complete processing of all the interrupt requests
from multiple LAN adapters.)
Where multiple LAN adapters are installed and used, check if the expected performance isreached on each built-in LAN adapter and additionally installed LAN adapter. If not,either adjust the load imposed by the network or change the LAN adapter settings
according to the procedure below. Refer details of each setting parameter to the help text
in the relevant display image.
1.

Do steps 1 through 4 in Subsection 3.10.3, “How to set up link speed and duplex
mode”.

2.

Click Advanced tab, select Performance Options in Settings list box, and click
Properties button (illustrated below).

3.

The “Performance Options” dialog box opens. Click each parameter in Settings list
box and confirm the current Value setting for the selected parameter. If you wish tochange the currently selected value, click Value drop-down list and change selection
to a new value. These actions are exemplified by lefthand screenshots following thesubsteps a. through e. below.
a. Adaptive Inter-Frame Spacing: Compensates for excessive Ethernet packet
collisions by dynamically controlling back-to-back timing.

3-20

3. OPERATION

b. Flow Control: Enables adapters to generate or respond to flow control frames,
which help regulate network traffic. Since the default setting varies depending on
the combination of the OS and LAN adapter interface, change the setting according
to your network environment.

< NOTE >In the event that the LAN driver is placed in the stopped state due to a system
failure such as OS lock-up, the receive queue may reach a pre-defined limit due tounprocessed broadcast frames and the like received from the other machines. In
this situation, the Equipment would continuously transmit flow control frames andaffect the entire networks to which the Equipment connects if “Generate” or“Generate & Respond” is selected for the flow control value. When necessary,disable the flow control by this Equipment or disable the flow control by the hub towhich the Equipment connects. Furthermore, apply an appropriate network design
to avoid possible overload, because receipt of excessive frames beyond thepredefined limit without flow control will cause overload and excessive frames will
be continuously discarded until resolution of such overload.
c. Interrupt Moderation Rate: Sets the rate at which the controller moderates ordelays the generation of interrupts making it possible to minimize network
throughput and CPU utilization.

3-21

3. OPERATION

d. Receive Buffers (previously called Receive Descriptors): Sets the number ofReceive Buffers used by the driver when copying data to the protocol memory.

e. Transmit Buffers (previously called Transmit Descriptors): Defines the number ofTransmit Buffers, which are data segments that enable the adapter to track transmit
packets in the system memory.

4.5 Setup of BIOS
The BIOS stores the system configuration information in the SPI-ROM. When the system
configuration is changed, the BIOS settings may have to be changed.
Note: The BIOS is optimally set to match the system configuration at shipping. Pay special
attention when you change the BIOS settings because the change may result inunstable operation or failure of system initialization. If you are not sure how to set up
the BIOS at system configuration change, contact our customer engineer.
(1) Starting setup menu
In order to set up the BIOS, start the setup menu by the following action:
Press the POWER switch (see Section 2.1, “External Views of Operator Access Areas”).
When the system initialization message is displayed, press the F2 key.

Sets up the reset button function. A
setting change to “NMI” gives you
more chances of non-maskableinterrupt, thereby increasing thepossibility of successful memory dump
initiated by the reset button at an error
occurrence during OS
startup/shutdown. For details of
memory dump, see Section 7.2,
“Memory Dump Collecting Feature”.
A setting change to “Enabled” causes
memory check processing to be
skipped, thereby shortening the startup
time. Keep the “Disabled” setting inpractical use.
Selects, upon encountering acorrectable ECC error, whether to stop
the ongoing startup and show amessage prompt to continue or cancel,
or to ignore such an error and continue
the startup.

*3 System startup initiated by connecting the input power cord and pressing the Power switch on the front panel
saves the current value of After AC Power ON. Because the backup battery is exhausted or not connected,
however, turning off of the main power by disconnecting the input power cord fails to save the current value andcauses this setting to be “Stay Off”.
*4 With “Disabled” Soft off setting, an attempt to shut down the OS does not automatically turn off the primary
power but shows the message that says “It is now safe to turn off your computer”.
*5 The default values are only read and are not saved in SPI-ROM. To save the setting contents into SPI-ROM,
use “Exit Saving Changes” subsequent to this option.

4.6 POST Code Indication
POST (Power On Self Test) is the function performed by the system power-on BIOS routinethat checks if the computer hardware such as memory, hard disk and keyboard has any fault.
Connecting the power supply to the Equipment causes the CPU to sequentially load thecontents of the BIOS ROM on the motherboard. If any fault is found, the digital LED for
status indication located in front of the Equipment shows a POST code corresponding to thefault location, along with a message on the monitor screen or several beeps, thus notifying
the user of a fault detection. The digital LED for status indication shows POST codes
during the startup of the Equipment.
The digital LED for status indication comprises 7-segment panels and status target
identification LEDs. The display content on these components may be carried over even in
the standby state after the shutdown, until the mains power is disconnected (by detaching the
input power cord plug from the outlet) or until the mains power is recycled (by keeping the
POWER switch pressed for four seconds or longer and then pressing the same switch again).
Note: For details of the other codes such as RAS status code, see Section 7.1, “Overview of
RAS Features” in this manual and HF-W2000 Model 35/30 RAS Features Manual.
POST codes on the digital LED for status indication are shown with the status target
identification LED for BIOS (orange) turned on. The codes are represented by the upperand lower digits in hexadecimal numbers 0 through F as illustrated below.

RMTSHTDN and GENDI use the same contact point (switched by RAS software setting).
RMTPWRON and GENDI2 use the same contact point (switched by a jumper pin).
When using RMTPWRON function, care has to be taken so that the external contact should not
be subjected to noise. If the contact becomes closed for 15ms or more because of a factor such as
noise during the Soft Power Off state, an inadvertent power on may result. While the OS or the
BIOS is running after the power is on, the RMTPWRON function is disabled and the contact
operates as GENDI2 input.

Use without replacement may
cause failure or short service lifeof the Equipment.

Based on the assumption that the HDD is used 24 hours per day. Even if your average usage isless than 24 hours a day, replacement is necessary when usage exceeds 4 years or total powered
time of 20,000 hours, whichever comes first. In addition, it is highly recommended that you
regularly back up your files in your daily operation so that you can quickly recover fromunlikely errors in your file contents.

5-3

5. INSPECTION AND MAINTENANCE

Notes:
1. The recommended replacement intervals listed above are valid when the Equipment is
operating at an average ambient temperature of 25°C or less. When the average ambient
temperature exceeds 25°C, these replacement intervals may be shortened.
2. This Equipment uses a lithium battery. When disposing of the battery, follow all local
regulations.
3. In the event of repair, there may be a case of replacement with functionally compatible
device or component.
4. Environmental conditions for the corrosion of this Equipment fall into the definition of
JEITA IT-1004A Class A (temperature of 25°C and humidity of 50%).
5. If the repair of this Equipment is performed by a third party, the functionality of thisEquipment will not be guaranteed.
6. There are cases when zinc whiskers cause an adverse effect on the electrical device.
Ensure that tin electroplating should not be used on the Equipment or a device near theEquipment.
 Reference: JEITA Technical Report ITR-1001 “Guideline of Facilities andEquipment for Information Systems” published by Japan Electronics and Information
Technology Industries Association (JEITA) Location liable to zinc whisker formation: Environment where tin electroplating isapplied, e.g., floor tile, stringer, strut, and anti-seismic support bracket.
 Effect: Electrical short circuit on a printed circuit board or connector terminal due tocontamination with electroconductive zinc whiskers. Such zinc whiskers may beformed under the raised floor, then somehow released in the room air, and finally get
into the Equipment or a device with the ventilation air. Because the resulting
symptom looks different depending on the affected area, it is difficult to identify any
cause and likely to be processed as a transient error. For this reason, failures causedby zinc whiskers tend to require longer time in finding out the root cause.

replacement in the event of a failure. Frequent detachment/attachment may
cause damage to the Equipment.
 On D Model, also observe the following: Do not altogether replace the two HDDs in RAID1 configuration.
 Since each D Model has its own RAID1 configuration information (e.g.,
serial number), you cannot swap HDDs even between D Models. If you
dare, the stored data in the newly installed HDD will be erased with
automatic RAID1 rebuilding process due to inconsistency of the RAID1
configuration information. If you own multiple D Models, manage use andinventory of HDDs so that they are not inadvertently mixed.
 Never remove the HDD if the corresponding HDD status lamp is off.
Otherwise, the stored data will be destroyed.
 Do not remove or insert an HDD when the “Hardware status” window cannot
be checked, for example, immediately after the OS starts. Otherwise, amachine failure or HDD failure may result.When you remove or insert an

Meaning
This counter indicates the CPU usage. If the valueof this counter remains high, the CPU performance
may become a system performance bottleneck.
Pages/sec
This counter indicates the number of pages per
second that are read/written between memory andthe disk to resolve page faults. If the value of thiscounter is high, the memory size may beinsufficient. The closer to zero the value is, themore adequate level the memory size is at.
Available Bytes
This counter indicates the physical memory size
allocatable to each process. If the value of thiscounter is on the decrease, a memory leak is suspect.
Pool Nonpaged Bytes This counter indicates the size of the memory areathat is not paged to the disk and stays in the physicalmemory as long as it is allocated (pool space). If thevalue of this counter is on the increase, a memory
leak is suspect.
% Disk Time
This counter indicates the disk busy rate due to disk
read or disk write. If the value of this counterremains high, the disk performance may become asystem performance bottleneck.
Bytes Total/sec
This counter indicates the number of bytes of data
per second sent or received on the network adapter.
If the value of this counter remains high ascompared to the “Current Bandwidth,” the network
adapter performance may become a system
performance bottleneck.
Current BandwidthThis counter indicates the bandwidth currently usedby the network adapter.

6. TROUBLESHOOTING< NOTE >Under Windows® 7, the system load monitoring with the Performance Monitor counters
may not start properly if the system is heavily loaded. After activating the system loadmonitoring with the Performance Monitor counters, ensure that the “Status” field of therelevant Data Collector Set shows “Running” as illustrated below.

< NOTE >Under Windows® 7, starting/stopping of the system load monitoring with the Performance
Monitor counters may become disabled (relevant buttons and menu items dimmed) if thesystem is heavily loaded or after the start/stop actions are repeated very often. In this case,exit Performance Monitor once, wait for a while, and then start Performance Monitor again.
If the disability persists thereafter, restart the system and start Performance Monitor again.

Memory Dump Collecting Feature
When any of the triggers in Table 7-1 occurs, the Equipment saves the system memory
contents into a file (memory dump file). At this time, a blue screen appears with a STOP
error code. You can troubleshoot the error by analyzing the contents of this memory dump
file. For details of the STOP error code, see Section 6.2, “STOP Error Code”.
Table 7-1 Triggers for Collecting Memory Dump
Trigger
Forced recovery fromCPU lock

Explanation
Press the RESET switch or send a remote reset signal to the external
control port RMTRESET when the CPU locked, and memory dump
will be collected.
Note: Do not send two or more remote set signals to the RMTRESET
port consecutively. Such consecutive input will cause the Equipment to
be unable to collect the memory dump.
Hardware NMI
At the occurrence of a severe hardware failure in the Equipment (e.g.,
uncorrectable memory error or PCI bus parity error), NMI(non-maskable interrupt) is automatically generated and memory dump
collection is triggered.
Microsoft® Windows® At the occurrence of a severe error in the kernel of Microsoft®
STOP error
Windows®, memory dump collection is triggered.

(1) Memory dump setup for Microsoft® Windows®
One type of memory dump file is selectable among the three options in the “System
Properties” window opened from Control Panel. Of these options differentiated by
the range of data, Complete Memory Dump (factory-set default) is recommended.
 Complete Memory Dump: The entire contents of system memory are saved. The
Boot Volume* needs to be allocated to accommodate a paging file that amounts tophysical memory size + 1 MB.
 Kernel Memory Dump: Only the contents of kernel memory are saved. The Boot
Volume* needs to be allocated to accommodate a paging file that amounts to one
third of physical memory size.
 Small Memory Dump: Only necessary minimum memory contents for identifying
the cause of STOP error on the Equipment are saved. The Boot Volume* needs tobe allocated to accommodate a paging file that amounts to at least 2 MB.
* “Boot Volume” means the volume containing Windows® and its support files.

< NOTE >Although Complete Memory Dump is factory-set on the Equipment with
Windows® 7 preinstalled, once this default setting is changed to any other type ofmemory dump, you cannot restore the setting to Complete Memory Dump via the“System Properties” window. For how to restore the setting under Windows® 7, see(2) (b) of Subsection 7.3.5, “Various setup procedures relating to memory dump”.
In the “System Properties” window, you can also set up virtual memory and automatic
restart after collection of memory dump. For the procedures of these settings, see
Subsection 7.3.5, “Various setup procedures relating to memory dump”.

The following figures provide the blue screen samples displayed when a failurecausing memory dump occurs or when the RESET switch is pressed. Although the
STOP error code at a forced recovery from CPU lock and the STOP error code at a

7. MAINTENANCE ACTIONS< NOTE > The time required for collecting memory dump varies depending on the targeted
type of memory dump, the installed drive configuration, and the installed memory
size. Be noted that Complete Memory Dump factory-set on the Equipment requiresa relatively long time. (If you install 4GB memory in the B model, it takes about 40
minutes for Windows® XP and about 60 minutes for Windows® 7.)
 There may be a case that the “Beginning dump of physical memory” message on
the blue screen is not followed by the progress rate of memory dump but halts.
This means that the memory dump processing failed because of an error in the filesystem or a disk error. If this symptom happens at a forced recovery from CPU
lock, at a hardware NMI, or at an uncorrectable memory error, record the upper fivelines of the STOP error message. Then, restart the Equipment either by pressing the
RESET switch or by recycling the power supply. For example, when a hardware
NMI has shown the screen (b) aforementioned, record the following lines:
Hardware malfunction.
***STOP :0x00000080(0x00000080,0x00003000,0x00000000,0x00000000)== Detailed Information ==0x9217: Uncorrectable Error at DIMM B

 In the above-mentioned case, however, if the symptom happens at a Windows®
STOP error, record the upper two lines of the STOP error message and then restartthe Equipment. For example, when a Windows® STOP error has shown the screen(c) aforementioned, record the following lines:***STOP.0x0000001e (0x0000009a,0x80123f36,0x02000000,0x00000246)

9. RAID1

CHAPTER 9 RAID1
9.1

What Is RAID1?
This chapter explains how to use the RAID1 functions peculiar to HJ-2035vwxyD (D Model)of HF-W2000 Model 35. References to the “Equipment” in this chapter only apply to
D Model of HF-W2000 Model 35. It is only an HDD that Equipment adopts.

NOTICE Although this Equipment featuring RAID1 is more reliable than generalsystems, it is still prone to the loss of data in the HDDs. Not only a machine
failure but also an unexpected power failure or an operation error may cause
data to be lost for good. To prevent such loss of data, implement scheduled
data backup in daily operation. Also, protect the power source fromundesirable interruptions by such means as UPS.
 This Equipment is evaluated based on the specific HDD models authorized by
the Manufacturer. Replace only with specific HDD models authorized by the
Manufacturer. Otherwise, the existing data in the HDD may be lost. Also,
always observe the recommended replacement interval for HDDs (Section 5.3,
“Replacement of Consumable Parts”).
 Since each Equipment has its own RAID1 configuration information (e.g.,
serial number), you cannot swap HDDs even between two units of thisEquipment. If you dare, the stored data in the newly installed HDD will beerased with automatic RAID1 rebuilding process due to inconsistency of the
RAID1 configuration information. If you own multiple units of this Equipment,
manage use and inventory of HDDs so that they are not inadvertently mixed.
 Each Equipment contains uniquely assigned HDD serial numbers in its own
RAID1 configuration information. Accordingly, if you create a copy of theexisting HDD without using the RAID1 rebuilding process, the copy will berecognized new and invalid. This new HDD, if installed in the drive bay, will
not start up the Equipment.
 Maintenance of a disk array system requires in-depth knowledge. In case ofan operation error, data in the HDD may be lost.
RAID1 (Redundant Array of Independent Disks Level 1) is a technique commonly known as
mirroring. The controller of the RAID1 divides the HDDs of an array into two groups andwrites the same data to both of them. Reading is performed from one of the groups. If an
HDD in one group should become faulty, the system can read from the corresponding normal
HDD of the other group. Although the Equipment uses two HDDs, the available disk
capacity is that of one HDD due to mirroring.
This Equipment graphically displays the HDD status of RAID1 by means of the built-in RAS
software. For how to use this RAS software, refer to Section 2.8, “RAID Monitoring
Feature” in HF-W2000 Model 35/30 RAS Features Manual. The display images in thischapter assume those under Windows® 7.

9-1

9. RAID1

9.2

Setup

9.2.1 Outline of setup
The built-in RAID controller causes the two HDDs connected thereto to be recognized as one
HDD to the Equipment, and performs jobs relevant to RAID1 by itself transparently to theEquipment. Accordingly, the Equipment does not require BIOS or device driver forcontrolling the RAID controller from the Equipment or OS. Since the Equipment treats these
HDDs as a common SATA HDD, no special procedure such as installation of specificsoftware is necessitated at the setup time.
9.2.2 Procedure of new setup

NOTICE When you newly build a RAID1 system on the Equipment, the setup process
writes the RAID1 configuration information, which only applies to this specificserial numbered Equipment. Since these HDDs containing such RAID1
configuration information are not usable on any other Equipment with adifferent serial number, manage handling and inventory of HDDs so that they
are not inadvertently mixed if you own multiple units of this Equipment. Shoulda wrong HDD be installed, the Equipment may not start up or you may lose
data stored in the HDD due to inconsistency of the RAID1 configuration
information.
 When you newly build a RAID1 system on the Equipment, prepare two newunits of specific HDD models authorized by the Manufacturer. If you use an
unauthorized HDD, you may lose data stored in the HDD.
To build a new RAID1 system on the Equipment, follow the procedure below. This
procedure is not necessary when you initially use the Equipment because a RAID1 system isfactory-set.
1. Prepare two new HDDs.
2. Shut down the OS, disconnect the power cord plug from the outlet, and wait at least one
minute. Then, mount new HDDs in drive bay 1 and drive bay 2, referring to
Subsection 5.4.3, “Detaching/attaching hard disk drive (HDD)” for details.
3. Turn on the Equipment by connecting the power cord plug to the outlet and pressing thePower switch on the front panel. The RAID controller automatically detects mounting of
the new HDDs and writes the RAID1 configuration information to both of these HDDs.
4. Install the OS using the Recovery DVD. (Refer to HF-W2000 Model 35/30 Setup
Guide.)

9.4.2 Recovering from HDD failure in one side

NOTICE Never remove the HDD if the corresponding HDD status lamp is off.
Otherwise, the stored data will be destroyed.
 To prevent damage due to static electricity discharge, wear cotton gloves
when you replace an HDD. Otherwise, the stored data may be destroyed.
 Before you ensure “Not Connected” status in the “Hardware status” window,
never mount a new HDD.
 Insert a new HDD firmly and precisely. A loose contact or a missing screw willcause a failure.
 Pay attention not to apply shock to the replacing HDD and the replaced HDD
during work, whether installed or not installed on the Equipment. Otherwise, afailure may result.
 Never shut down the OS or perform the HDD detachment/attachment work
before the RAID1 rebuilding process is complete. Otherwise, the stored datain the HDD may be lost or a failure may result.
< NOTE >The procedure in this subsection assumes that you are to replace an HDD while theEquipment power is on. If you are to replace an HDD while the Equipment power is off, first
identify the failing HDD and then follow the steps of Subsection 9.5.3.1 “Replacing an HDD
in RAID1 while the Equipment power is off”. After completion of the rebuilding process,restart the Equipment and ensure that the RAID status for the drive bay number to which the
new HDD is attached shows “Healthy” in the “Hardware status” window. If the RAID statusshows “Optimal (Media Error)”, follow the step 9 of Subsection 9.4.2 “Recovering from

Preventive Maintenance9.5.1 Creating backup HDD

NOTICE
 To prevent damage due to static electricity discharge, wear cotton gloves
when you replace an HDD. Otherwise, the stored data may be destroyed.
 Observe the work order and follow the given instructions. Otherwise, thestored data may be lost.
Although the RAID1 system is more reliable than general systems, it is still prone to the lossof data stored in the HDD due to a misoperation or other causes. Preparation of a backup
HDD would then enable you to restore the lost data (up to the moment when the backup was
taken). It is recommended that you prepare a new HDD and regularly keep the backup copy
according to the procedure below.
Note: The procedure below assumes the steps to create a backup HDD from the HDD
installed in drive bay 1. When you create a backup HDD from the HDD installed in drivebay 2, read “drive bay 1” and “HDD1 status lamp” in the steps below as “drive bay 2” and“HDD2 status lamp”.
1. Prepare a new HDD.
2. Shut down the OS, disconnect the power cord plug from the outlet, and wait at least one
minute. Then, replace the HDD in drive bay 1 with a new HDD according to
Subsection 5.4.3, “Detaching/attaching hard disk drive (HDD)”.
3. Store the detached HDD in a safe place. Keep it as a backup HDD.
4. Turn on the Equipment by connecting the power cord plug to the outlet and pressing thePower switch on the front panel. The RAID controller automatically detects mounting of
the new HDD and starts the RAID1 rebuilding process. Ensure that the HDD1 statuslamp blinks.
5. Along the progress of the rebuilding process, the OS starts up. Time required for therebuilding process depends on what application programs are running during the process.
Accordingly, it is suggested that you do not run any application program until therebuilding process is complete.
Note: If you do not want to start up the OS, activate the BIOS setup menu by pressing
the F2 key while the system initialization message (BIOS memory check) is displayed orwhen the digital LED for status indication shows “C0”. In the background, therebuilding process continues. Let it run to completion for about 70 minutes on a 160GB

9.5.3 Performing periodical HDD replacement

NOTICE
 Do not replace with an HDD previously used in any RAID level. Otherwise, theEquipment may not start up or you may lose data stored in the HDD due toinconsistency of the RAID1 configuration information or similar cause.
 Selecting a wrong HDD as the target will erase the data stored in the HDD.
Fully ensure the drive bay number for the target HDD on the Equipment at theuser’s responsibility.
 Do not altogether replace the two HDDs in RAID1 configuration.
 To prevent damage due to static electricity discharge, wear cotton gloves
when you replace an HDD. Otherwise, the stored data may be destroyed.
 When you replace an HDD while the Equipment power is on, first stop thepower supply to the target HDD by placing the HDD into OFFLINE state in the“Hardware status” window. Never attempt HDD replacement before thiswindow is ready (e.g., immediately after the OS startup). Otherwise, amachine failure or HDD failure may result.
The HDD is a consumable part with its life, requiring periodical replacement in about 2-year
intervals (assuming use of 24 hours per day). At each periodical replacement, follow thesteps of Subsection 9.5.3.1 or Subsection 9.5.3.2 as applicable. Because these steps include
RAID1 rebuilding process, you must not altogether replace the two HDDs comprising the

10. SOFTWARE RAID1

CHAPTER 10 SOFTWARE RAID1
10.1 Overview of Software RAID1
This chapter explains how to use the software RAID function of the equipment model HJ2030****B (B model).
In this chapter, “the Equipment” means HJ-2030****B (B model). HDDs are the only drives
the Equipment uses for the software RAID function, and therefore, a drive is denoted as“HDD” in the following explanation.

NOTICE The Equipment features RAID1 and is highly reliable compared to a systemwith a conventional configuration. Nonetheless, the data stored on the HDDs
may be lost depending on the type of the failure. In addition to equipment
failure data can also be lost by power failure and human mistakes during
operation. Should such situation occur, the data cannot be recovered. In orderto prevent data loss, make it a routine to save your data and establish asystematic way of backup. In addition, increase the reliability of power supply
by, for example, using a UPS.
 The Equipment is evaluated under the assumption that the HDD models
specified by HITACHI are used. When you replace an HDD, use the HDD
models specified by HITACHI. Otherwise, the data stored in the HDDs may belost. Stick to the recommended replacement cycle when you replace an HDD.
(See Section 5.3, “Replacement of Consumable Parts”.)
 The Equipment manages the unique serial number of each HDD (each HDD
has a different serial number) as part of RAID1 configuration information.
Therefore, if you copy the contents of an HDD to another HDD without using
the rebuild function of the software RAID1 construction utility, the HDD withthe copied contents is recognized as an invalid medium. Even if you mount the
HDD to a drive bay, the Equipment will not start.
 Maintenance of a disk array system requires a high level of expertise. Should
any mistakes be made during the maintenance work, data stored in the HDDs
may be lost.

RAID1 (Redundant Array of Independent Disks Level 1) is a technology generally referred
to as “mirroring”. The software RAID1 does not use a RAID controller (hardware) for
mirroring but uses software to implement RAID1. Should either one of the HDD pair fail,you can read out data from the other working HDD. RAID1 uses two HDDs but the available
capacity is the capacity of one HDD.
The Equipment graphically shows the status of HDDs used for software RAID1 using the
RAS software. For information about how to use the RAS software, refer to Section 2.8,
“RAID Monitor Function” in the “HF-W2000 Model 35/30 RAS Features Manual”. Screen
images of the hardware status window in this chapter are examples from Windows® 7.
The Equipment comes with the software RAID1 construction utility “Software RAID1 For

10-1

10. SOFTWARE RAID1

Windows(R)”. By using this utility, you can check the status of the software RAID1 andrebuild RAID1. For information about how to use the utility, see Section 10.6, “Software
RAID1 construction utility”.

10-210. SOFTWARE RAID1

10.2 Setup
10.2.1 Overview of setup
The software RAID1 device driver used for the RAID1 on the Equipment enables the OS torecognize two HDDs connected to the Equipment as one HDD and is responsible for dataprocessing associated with mirroring. The software RAID1 device driver has been alreadyinstalled when the product is shipped, and you do not need to install it when you set up
RAID1.
10.2.2 Setting up from scratch

NOTICE When you build software RAID1 from scratch, the unique serial number of
each HDD (each HDD has a different serial number) is stored in the HDDs aspart of RAID1 configuration information. If you use multiple sets of Equipment,
pay attention when you handle and store the HDDs so that the HDDs are notmixed up. Otherwise, RAID1 configuration information mismatch occurs, andthe Equipment may not start up, and the data in the HDDs may be lost.
 When you build software RAID1 from scratch, prepare two new HDDs
selected from the models specified and tested by HITACHI. Otherwise, thedata stored in the HDDs may be lost.

Follow the procedure below when you build software RAID1 from scratch.
Be noted that, when the product is shipped, software RAID1 has been already built, and thefollowing procedure is not necessary.
1. Prepare two new HDDs.
2. Shut down the OS, and pull out the plug of the power cable from the outlet. Wait one
minute or more, and then mount new HDDs to the drive bay 1 and 2. (For information
about how to mount an HDD, see Subsection 5.4.3, “Detaching/attaching hard disk drive(HDD)”.)
3. Connect the plug of the power cable to the outlet, and turn on the power for theEquipment.
4. Install the OS from the recovery DVD.
(Refer to the “HF-W2000 Model 35/30 Setup Guide”.)

hard disk drive (HDD)”.) After the HDD is replaced, try to rebuild RAID1 again.
(2) When the Equipment started up with incorrect RAID configuration
When you mount an HDD used for another HJ-2030****B (B model) or an HDD
previously used for backup by mistake during HDD replacement and try to start up the OS
without rebuild, the Equipment displays a blue screen and stops there in order to prevent it
starting up. If this happens, the blue screen shows the following.
***STOP :0x00009502（ 0x00000000,0x00000000,0x00000000,0x00000000）
Array configuration is not correct.
Please refer to HF-W instruction manual for more information.

If you see this screen, remove the HDD mounted by mistake. (For information about how
to remove on HDD, see Subsection 5.4.3, “Detaching/attaching hard disk drive (HDD)”.) In
addition, after removing the HDD, follow Step 2 through 5 described in Subsection 10.5.3,“Performing periodical HDD replacement”.
10.4.6 Recovering from HDD failure in both sides
After you replace both HDDs, set up the Equipment again, and recover the data frombackup files (See Subsection 8.1, “Backing Up Files”.)
Or, recover the Equipment using a backup HDD. (See Subsection 10.5.2, “Performing
restoration from backup HDD”.)

10.5 Preventive Maintenance10.5.1 Creating backup HDD

NOTICE
 Do not use an HDD previously used for software RAID1 in place of a new
HDD. Otherwise, the Equipment may not start up or the data in the HDDs may
be lost because of RAID1 configuration information mismatch or otherreasons.
 Do not create a backup HDD by mounting a new HDD and then rebuilding
RAID1. The RAID1 configuration information stored in each HDD is updated
after RAID1 is rebuilt. Therefore, even if the previous HDD is reinstalled after
the rebuild is complete, the Equipment may not start up or the data in the
HDDs may be lost due to RAID1 configuration information mismatch or otherreasons.
 Wear cotton gloves when replacing an HDD in order to prevent failure causedby static electricity. Otherwise, the data in the HDDs may be corrupted.
 During the work, make sure you follow the correct procedure. Should any
mistakes be made, the data stored in the HDDs may be lost.

RAID1 is highly reliable compared to a system with a conventional configuration.
Nevertheless, the data stored in the HDDs may be lost due to human errors or other reasons.
If you create a backup HDD, you can recover from such data loss. (Note that you can only
restore from the point of backup.) We recommend that you backup periodically using a new
HDD and the software RAID1 construction utility “Software RAID1 For Windows(R)”.
Follow the procedure below to create a backup HDD.
(Note) The following procedure is for the HDD mounted in the drive bay 1.
When you create a backup HDD from the HDD mounted in the drive bay 2, replace thedrive bay 1 with the drive bay 2 in the procedure.
1. Shut down the OS, and pull out the plug of the power cable from the outlet. Wait one
minute or more, and then replace the HDD mounted in the drive bay 1 with a new HDD.
(For information about how to replace on HDD, see Subsection 5.4.3,“Detaching/attaching hard disk drive (HDD)”.)If any external storage devices are connected to the Equipment, disconnect them.
2. Store the removed HDD in a safe place as a backup HDD.
3. Turn on the power for the Equipment. Before the OS starts, insert the software RAID1
construction utility “Software RAID1 For Windows(R)” into the DVD drive.

10.7 Backing Up under the Offline Situation
The Equipment processes mirroring with the software RAID1 device driver running on the
OS. If you perform backup-related work (creating or restoring from backup data) under theoffline situation without running the OS, you need to consider the configuration of thesoftware RAID1 because you can independently access each HDD used by the software
RAID1.
This section explains the procedure and what you need to know when you create or restore
from backup data under the offline situation.
The offline situation mentioned here means, for example, an environment started up by
Windows® 7 Windows Recovery Environment (Windows RE) or the startup disk ofcommercially available backup software.
<Procedure of creating backup data>
1. Follow the recommended procedure of your backup software to create backup data.
2. Rebuild RAID1 using the HDD used as the source of backup data as a copy source. (Forinformation about rebuilding RAID1, see Subsection 10.6.4, “Rebuild function of
RAID1”.)< NOTE >• When you create backup data for the system operating in fall-back mode, it is possiblethat you specify the already disconnected HDD for the source of backup data by mistake.
Make sure that the HDD used as the source of backup data is in the normal state(ONLINE). (For information about how to check the status of an HDD, see Subsection
10.6.3, “Status display function for RAID1”.)• Depending on the backup software you use, the backup software may write something to
an HDD while creating backup data. Because of this, do not forget to rebuild RAID1
after you created backup data so that both HDDs in the drive bay 1 and 2 have the samedata.
<Procedure of restoring from backup data>
1. Mount an HDD on both the drive bay 1 and 2.
2. Perform backup restoration preparation. (For information about backup restoration
preparation,see Subsection 10.6.6, “Backup restoration preparation function”.)
3. Follow the recommended procedure of your backup software to copy the preserved
backup data to the HDD in the drive bay 1 for restoration.
4. Rebuild RAID1. (For information about rebuilding RAID1, see Subsection 10.6.4,“Rebuild function of RAID1”.)

10. SOFTWARE RAID1< NOTE >• If you forgot to perform backup restoration preparation and specify an HDD that has
never been used on the Equipment (a new HDD, for example) for the HDD where thebackup data is restored, the HDD does not have RAID1 configuration information andyou cannot use it as a part of software RAID1 even if you restore the backup data there.
• The backup restoration preparation function configures the HDDs so that the direction of
the rebuild is from the HDD in the drive bay 1 to the HDD in the drive bay 2. Make sure
you copy the backup data to the HDD in the drive bay 1 for restoration.
• If you restore from backup data under the offline situation, the HDD is accessed without
the software RAID1 device driver, and data mismatch between the HDDs in the drive bay
1 and 2 is inevitable. Because of this, do not forget to rebuild RAID1 after you restored
backup data so that both HDDs in the drive bay 1 and 2 have the same data.
