hot-swap a device. If you do either of these, failure of the built-in equipment
may result.
(Page 5-34)
 Although this Equipment featuring RAID1 is more reliable than generalsystems, it is still prone to the loss of data in the HDDs. Not only amachine 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 thepower 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.
 Use a brand-new HDD (an unused HDD) or an HDD to which "Initialize Drives"
has been applied (see "8.2.2 Building RAID1") as a replacement HDD.
 Do not reverse the mounting locations of two HDDs. If you do, rebuild may notstart automatically when a replacement HDD is mounted to recover from a failure
in one HDD.
 Maintenance of a RAID1 system requires a high level of expertise. Should any
mistakes be made during the work, the data stored on the HDDs may be lost.
 When HDD1 and HDD2 are installed, their capacities must be the same.
(Page 8-1)
 As a replacement HDD, do not use an HDD previously used in the A model orthe D model. If you do, this equipment may not operate properly or the data on
the HDDs may be lost because of configuration information mismatches or otherreasons.
(Page 8-1)(Page 8-20) (Page 8-39)

S-15

SAFETY INSTRUCTIONS (Continued)
 When a RAID1 system is newly built, the RAID1 configuration informationis recorded on the HDDs. This configuration information can only be used by
the piece of equipment that uses this individual RAID1 system. An HDD
with this configuration information cannot be used by other pieces ofequipment. If a user uses multiple pieces of equipment, regardless of whether
they are A models or D models, the user needs to be cautious when handlingand storing the HDDs in order not to mix them up. If HDDs are mixed up, a
RAID1 configuration information mismatch occurs. The equipment may not
operate properly, and the data on the HDDs may be lost.
 When you build a RAID1 system from scratch, prepare two new HDDs
selected from the models specified and tested by HITACHI. Otherwise, thedata stored on the HDDs may be lost.
 When you build a RAID1 system from scratch, use the recovery DVD andinstall the OS from scratch.
 Care must be taken when you build a new RAID 1 system on an existing
RAID1 system. The setup process will completely overwrite the existing
RAID configuration information and you will no longer be able to use theexisting RAID 1 system.
(Page 8-8)
 Never remove an HDD when the HDD status lamp of the HDD is OFF.
If you do, the data stored in the HDD gets corrupted.
 Mount an HDD securely. Loose contacts and missing screws may result in a
failure.
 Do not subject an HDD you are mounting and the already mounted HDDs toshock while replacing an HDD. Otherwise, failure of the equipment may result.
 Until the rebuild is complete, avoid shutting off the power for this equipment or
attaching and detaching HDDs. Otherwise, the data on the HDDs may be lost ora failure may result.
(Page 8-20)
 Wear cotton gloves when replacing an HDD in order to prevent problems
caused by static electricity. If you do not, the data stored on the HDD may
get corrupted.
 Make sure you check the correct procedure before you start the work. If you
do not follow the correct procedure, the data stored on the HDD may be lost.

 If you apply the recovery method for an offline HDD to an HDD that was set
to offline by something other than the RAS software, the HDD may not berecovered, or even if it is recovered, the HDD may not work properly.
 Use the recovery method for an offline HDD only for the purpose of evaluating
the equipment. If you apply the recovery method for an offline HDD toequipment actually used in the field, for example, a system in normal operation,
malfunctions may result, including data loss.
 If an HDD is automatically set to offline by the equipment, the HDD may
possibly be out of order. Do not apply the recovery method for an offline HDD
to such an HDD.
 An HDD recovered by the recovery method for an offline HDD must not be
used for equipment actually used in the field. If used, malfunctions may
result, including data loss.
(Page 8-32)
 Do not replace the two HDDs at the same time. If you do, the data getscorrupted.
 When you replace an HDD, make sure that you set the HDD into the offlinemode in the Hardware status window, and then remove that HDD andmount the replacement HDD. If you mount or remove an HDD when the
hardware status cannot be checked, for example, immediately after the OS
starts, a failure may result.

・It is reported that zinc whiskers can cause a problem with the device. Do not use electrogalvanized material near or at the place where the equipment is installed.
(A quote from the Technical Report of JEITA(*) ITR-1001 “Guideline of Facilities andEquipment for Information Systems”)
Location of whiskers: Whiskers are created by electrogalvanized equipment such as
floor panels, stringers, posts, aseismatic flat steel, and the like.
Phenomenon: Hair-like zinc crystals (conductive whiskers) float into the air from thefloor for some reason, go inside the device, and short-circuit a PCB or its pins.
The root cause is difficult and time-consuming to find because the symptom
differs depending on the location of the short circuit, and often, it is mistaken fora temporary issue.

rack mounting metal fittings, see Subsection 1.2.2 Installation (b), “Rack mount.”• Elevated Operating Ambient:
If installed in a closed or multi-unit rack assembly, theoperating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consideration must be given to installing the equipment in anenvironment compatible with the maximum ambient temperature specified in
Subsection 1.2.1 Environment.
• Reduced Air Flow:
Installation of the equipment in a rack must be such that theamount of air flow required for safe operation of the equipment is not compromised.
• Mechanical Loading:
Mounting of the equipment in the rack must be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading:Consideration must be given to the connection of theequipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration ofequipment nameplate ratings must be used when addressing this concern.
• Reliable Earthing:
Reliable earthing of rack-mounted equipment must be
maintained. Particular attention must be given to supply connections other than directconnections to the branch circuit (e.g., use of power strips).
「Français」
Les instructions de montage en rack suivantes ou similaires à celles-ci sont fournies avec
les instructions d'installation :• Température ambiante de fonctionnement élevée : en cas d'installation dans un châssis
fermé ou contenant plusieurs appareils, la température ambiante de fonctionnement au
niveau du rack peut être supérieure à la température ambiante de la pièce.
En conséquence, il convient de veiller à installer le matériel dans un environnementcompatible avec la température ambiante maximale (Tma), spécifiée par le fabricant.
• Débit d'air réduit : l'installation du matériel dans un rack doit être effectuée de façon à
ne pas compromettre le débit d'air nécessaire pour un fonctionnement sûr de ce
matériel.
• Charge mécanique : le montage de l'équipement en rack doit être réalisé de manière àéviter toute situation dangereuse résultant d'une charge déséquilibrée.
• Surcharge de circuit : il convient de prendre les précautions nécessaires pour laconnexion du matériel au circuit d'alimentation et de réfléchir aux conséquences d'uneéventuelle surcharge des circuits sur la protection de surintensité et sur le câblage
d'alimentation. En l'occurrence, les valeurs nominales de la plaque signalétique dumatériel doivent être prises en compte.
• Mise à la terre fiable : une mise à la terre fiable du matériel monté en rack doit êtreassurée. Une attention toute particulière est requise pour les raccordements
d'alimentation autres que ceux effectués directement sur le circuit principal (parexemple, en cas d'utilisation de blocs multiprises).

Controlling the Power Using the LAN
The power for this equipment can be turned on from a remote device by way of the LAN.
This section explains WOL (Wake ON LAN™), which is used for turning on the power forthe equipment through the LAN. When the power is turned on by using WOL, the equipment
is started by sending a Magic Packet™ frame to the LAN interface when the standby lamp
(STBY) is on.
In the initial factory settings, this function is disabled. If you want to use this function,
follow steps 1 through 3 described in “3.7.1 Enabling the WOL (Wake ON LAN™)
function” to enable the WOL function and then follow the steps below.
< NOTE >・ For information about the precautions for the network, see “PRECAUTIONS 2.
NETWORK”.

3.7.1

Enabling the WOL (Wake ON LAN™) function
By following the procedure below, you can set up whether to start WOL when a
Magic Packet™ frame is received. In the initial factory settings, the WOL function isdisabled. (The display image assumes Windows® 7 but it is similar under Windows
Server® 2008 R2. Note that the WOL function is not available in Windows Server®
2012 R2 due to its specifications.)
1. Execute steps 1 though 7 in “● Setting up the network transfer speed” in “3.8Setting Up the LAN Interface”.
2. Click the Power Management tab. If you want to enable WOL, select the Wakeon Magic Packet from power off state check box under Wake on LAN :.
3. Click OK and restart the system.

3-7

3. OPERATION

3.7.2

Turning on the power using the LAN
1. Insert the plug of the power cord into an outlet and turn on the main power. The
standby lamp (STBY) will be lit.
2. Send a Magic Packet™ frame to the built-in LAN adapter in the equipment. Whenthe built-in LAN adapter receives a Magic Packet™ frame, the power for theequipment is turned on.
You must turn on the standby lamp (STBY) in order to start the equipment throughthe LAN (using WOL). If you start the equipment and you want to continue to use
WOL at the next startup, go through the shutdown process when you turn off thepower.
The built-in LAN adapter in the equipment is compliant with WfM 2.0 (*1) tosupport the Magic Packet™ technology. Because of this, the power for the equipment
can be turned on when a special data packet called a “Magic Packet™ frame” (*2) isreceived at the built-in LAN adapter.
A program for transmitting a Magic Packet™ frame does not come with theequipment. Use a commercially available program for to transmit the Magic Packet™
frame.
(*1) Wired for Management (WfM) is a guideline regarding the hardware
specifications proposed by Intel Corporation for managing PCs on a network.
(*2) The Magic Packet™ technology has been proposed by AMD Japan, Ltd. andcan be starting a PC on a network from a remote device.

< NOTE >・ When you send a Magic Packet™ frame to the equipment, make sure you
send it to the built-in LAN adapter in the equipment. (For information about thelocation of the connector, see “2.1 Display and User Input Sections”.) You
cannot use WOL if you send a Magic Packet™ frame to an optional LAN
adapter.
・ If you turn off the power by pressing the power switch for at least four seconds,
you cannot use WOL the next time. When you turn off the power by pressing
the power switch for at least four seconds, turn on the equipment by pressing
the power switch and go through the shutdown process to turn off the power.

3. OPERATION< About the Magic Packet™ frame >In a Magic Packet™ frame, the SOURCE ADDRESS, DESTINATIONADDRESS (the MAC address of the receiver or the MULTICAST ADDRESS
including the BROADCAST ADDRESS), CRC, and the like must meet the basic
requirements of the LAN in use. The data in a Magic Packet™ frame consists of asequence of 16 repetitions of the MAC address of the node. This sequence can be
anywhere in the packet but it must follow a synchronization stream. The
synchronization stream is defined as 6 bytes of 0xFF. As long as the MAC addressthat repeats itself 16 times targets the address of the equipment to be started, thedevice can receive a BROADCAST frame.

3. OPERATION● Precautions for mounting and using multiple LAN adapters
If multiple LAN adapters are mounted and there are frequent interrupt requests fromeither of the adapters or the amount of processed data is too large, the performance of
the adapters may not be as high as expected. (This is because an interrupt request froma LAN adapter requires a higher CPU load compared to the amount of processed dataand if multiple LAN adapters are mounted and used, it takes a very long time for the
CPU to process all interrupt requests from the LAN adapters.)
If you mount and use multiple LAN adapters, confirm that each built-in LAN adapter
and optional adapter can perform as expected. If they do not, adjust the network load orchange the LAN adapter settings by following the procedure below. For details about
each configuration item, see the description at the bottom of the corresponding setup
window. (The display image assumes Windows® 7 but it is similar under Windows
Server® 2008 R2.)
1. Execute steps 1 though 7 in “● Setting the network transfer speed” in “3.8 Setting
Up the LAN Interface”.
2. Click the Advanced tab. Select Performance Options and click Properties. The
Performance Options dialog box is displayed.
(In Windows Server® 2012 R2, click the Advanced tab. Then under Property, selectthe items described in the following.)

3. OPERATION・ Adaptive Inter-Frame Spacing
This compensates for excessive Ethernet packet collisions by dynamicallycontrolling back-to-back timing.

・ Flow Control
This enables adapters to generate or respond to flow control frames, which help
regulate network traffic. The default setting of the flow control is different
depending on the OS and the type of LAN adapter in use. You must configure
the flow control setting according to the network you are using.

< NOTE >・ If the LAN driver stops due to a system failure such as an OS deadlock,broadcast frames from other devices may not be able to be processed and thereceive queue may get full.
If Rx Enabled or Rx & Tx Enabled is specified for Flow Control, flow control
frames are continuously sent from this equipment under such a condition. If
this happens, that may affect the whole network connected to the equipment.
Specify Disabled for Flow Control at this equipment or at the connected hub
as required.
・ If Disabled is specified for Flow Control and if the device receives frames
quicker than it can process, the device gets overloaded, and the frames
receive will be discarded until the device recovers from the overload condition.
You have to design the network appropriately to avoid such an overload
condition.

3-17

3. OPERATION

・ Interrupt Moderation Rate
This sets the rate at which the controller moderates or delays the generation ofinterrupts.

・ Receive Buffers
This sets the number of Receive Buffers used by the driver when copying data to
protocol memory.

・ Transmit Buffers
This sets the number of Transmit Buffers, data segments used by the adapter
when recording transmission packets in system memory.

3. OPERATION● Notes about the case when link down is recorded in the log during OS startup.
While Windows® is starting, the following warnings may be displayed in the event
log. These warnings are recorded by the initialization process of the LAN driver at thestartup of Windows® and will not cause any problems in the system operation.

Collecting a Memory Dump
When one of the errors in Table 7-1 occurs, this equipment records the contents of thesystem memory in a file (memory dump file). Then a blue screen appears and a STOP error
code is displayed. By analyzing the data in this memory dump file, you can investigate thecause of the failure.
Table 7-1

Error That Trigger a Memory Dump

Cause
Forced recovery from OS
hang

Description
When the OS hangs, press the reset switch or input a remote reset
signal to the external contact RMTRESET (*1).
Then a memory dump is collected.
Hardware NMI
When a severe failure (such as uncorrectable memory error or a PIC
bus parity check error) occurs in the hardware of this equipment, anon- maskable interrupt (NMI) is generated and a memory dump iscollected.
Microsoft® Windows®
When a fatal error occurs in the Microsoft® Windows® kernel, a
STOP error
memory dump is collected.
(*1) Do not input a remote reset signal continuously to the RMTRESET external contact.
If you do, this equipment cannot collect a memory dump.

For details about the displayed STOP error code, see “6.3 STOP Error Codes”.
To select the memory dump file type, open System in Control Panel. You can select from thefollowing three types defined below (four types in Windows Server 2012 R2). Because thememory dump file type determines how far you can analyze the failure by using the dump
file, we recommend selecting “Complete memory dump” whenever you can. The factory
default is “Complete memory dump”.
The entire contents of system memory is recorded.
・ Complete memory dump
The boot volume (*2) must have enough free space tohold a paging file equal to the size of the physicalmemory plus 1 MB.
・ Kernel memory dump
The kernel memory is recorded.
The boot volume (*2) must have enough free space tohold a paging file about one third the size of thephysical memory.
・ Minimum memory dump
The minimum information necessary for identifying
what caused the equipment to stop is recorded. Theboot volume (*2) must have enough free space to holda paging file of more than 2 MB.
・ Automatic memory dump (*3) Similarly to the kernel memory dump, the kernel
memory is recorded.
The difference from the kernel memory dump is that
the Auto memory dump can make the initial paging filesmall from the physical memory size.
(*2) The boot volume is a volume that contains Windows® files and Windows® support
files.
(*3) Available only in Windows Server 2012 R2.

7-6

7. MAINTENANCE OPERATIONSIn order to collect a complete memory dump file, you need a memory dump file of a size
comparable to the capacity of the physical memory. In addition, the virtual memory (pagefile) and memory dump settings must be the ones recommended for this equipment (*4).
(*4) This means the settings in the Advanced system settings in the Control Panel are as
follows. These settings are preset in this equipment when the equipment is shipped fromthe factory.
・ In the Startup and Recovery, Complete memory dump is selected as memory
dump type.
・ In the Startup and Recovery, Overwrite any existing file is selected.
・ In the Performance, the Initial size and Maximum size of the virtual memory is
the physical memory size plus 300MB.
<Examples of blue screens>
The following shows examples of screens displayed after an incident occurs that triggers
a memory dump or after the reset switch is pressed.”Forced recovery from OS hang” and“Hardware NMI” share the same STOP error code, but if you look at the detailed
information displayed under the STOP error code, you can determine what caused thememory dump to be collected.

7. MAINTENANCE OPERATIONS< NOTE >・ The time required for collecting a memory dump depends on the type of dump
file collected, the configuration of the mounted drives, and the memory capacity.
It should be noted that if you keep the factory setting, “Complete memory dump”,
for the memory dump file type, the time required may be extremely long.
In the D model, memory dump takes about two minutes before it is started.
・After “Beginning dump of physical memory” is displayed on the blue screen, thecount on the screen that shows the progress of the memory dump sometimes
stops being updated. This is because collection of the memory dump failed due
to an error of the file system or a hard disk.
If this happens, record the first five lines of the STOP message screen. Thenpress the reset switch or turn the power off and then back on to restart theequipment. For example, if a hardware NMI occurs, the screen in (b) isdisplayed, so the following information must be recorded.

Hardware malfunction.

As an exception, in the case of a Windows® STOP error, only the first two lines of the
STOP message screen are needed. For example, if the screen in (c) above is displayed,
the following information must be recorded.

dump fails because the disk capacity is insufficient. By using this command, you can avoid afailure in collecting a memory dump caused by a lack of disk capacity.
The createdmp command reserves a disk area if the following conditions are met. If thoseconditions are not met, the command terminates with an error. Make sure that the memory
dump settings are appropriate and then retry this command. For information about how to set
up the memory dump settings, see “7.2.2 Configuring settings related to a memory dump”.
・ A “Complete memory dump” is specified to be collected.
・The file name of the memory dump must be correctly input.
・The memory dump file must be able to be overwritten.
・After the area for the memory dump file is allocated, the partition used for allocation still
has free space of at least 10 % of the disk capacity:
The size of the disk area to be allocated is as follows.
・ The size of the physical memory size plus 10 MB.
< NOTE >・ When you run the createdmp command, log on to the computer by using an
administrator account registered on the computer (as a member of the
Administrators group). You cannot run multiple instances of the createdmp
command simultaneously.
・If User Account Control (UAC) is enabled, start the command prompt withadministrator privileges according to “7.4 (1) Starting a command prompt” and7-19

8. RAID1

CHAPTER 8 RAID1
8.1 What Is RAID1 ?
This chapter describes how to manage the RAID1 feature of the D model.
In this chapter, "this equipment" denotes the D model. Note that only HDDs (hard disk drives)
are used as a drive for this equipment. A drive is denoted simply as "HDD" in the following
explanation.
The screen images shown in this chapter are the ones for Windows® 7, but the displayedcontents are basically the same for Windows Server® 2008 R2 and Windows Server ® 2012 R2.

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 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.
● As a replacement HDD, do not use an HDD previously used in the A model orthe D model. If you do, this equipment may not operate properly or the data on
the HDDs may be lost because of configuration information mismatches orother reasons.
● Use a brand-new HDD (an unused HDD) or an HDD to which "Initialize Drives"
has been applied (see "8.2.2 Building RAID1") as a replacement HDD.
● Do not reverse the mounting locations of two HDDs. If you do, rebuild may notstart automatically when a replacement HDD is mounted to recover from a
failure in one HDD.
● Maintenance of a RAID1 system requires a high level of expertise. Should any
mistakes be made during the work, the data stored on the HDDs may be lost.
● When HDD1 and HDD2 are installed, their capacities must be the same.

8-1

8. RAID1

RAID1 (Redundant Array of Indepensive Disks Level 1) is a technology generally referred
to as "Disk mirroring". Two HDDs are combined and managed as one RAID1 system (array).
In a RAID1 system, the same data is written to the two HDDs. When reading data, both HDDs
are accessed. Should one HDD fail, you can read correct data from the other HDD. RAID1
uses two HDDs but the capacity available is only equal to the capacity of one HDD.
This equipment shows the status of HDDs used for RAID1 graphically, using the RAS
software. For information about how to use the RAS software, refer to "Section 2.8" in the
HF-W7500 Model 40 RAS FEATURES MANUAL (Manual Number WIN-63-0090). Note thatscreenshots used in this chapter are shown only as examples. The model name, capacity, andother information about an HDD shown here may be different than those shown in an actual
working system.
< NOTICE >・If you replace an HDD after the "Adaptec RAID Configuration Utility" (see "8.2.1 RAID BIOS Menu")
starts, the new HDD is displayed as "Ex00: Phy255..." in the "Select Hotspare drives" item.
Nevertheless, rebuild will not be affected by this error in the display.When the equipment is restarted,
this error in the display will be corrected.
・ In the case of Windows Server®2012 R2, " ADAPTEC Virtual SGPIO 0 SCSI Enclosure Device " isdisplayed on a Device Manager of Windows by the section of "Other devices", but there is no problem
with the RAID function.

8. RAID1

8.2.2 Building RAID1NOTICE● When a RAID1 system is newly built, the RAID1 configuration information isrecorded on the HDDs. This configuration information can only be used by thepiece of equipment that uses this individual RAID1 system. An HDD with thisconfiguration information cannot be used by other pieces of equipment. If auser uses multiple pieces of equipment, regardless of whether they are A
models or D models, the user needs to be cautious when handling and storing
the HDDs in order not to mix them up. If HDDs are mixed up, a RAID1
configuration information mismatch occurs. The equipment may not operateproperly, and the data on the HDDs may be lost.
● When you build a RAID1 system from scratch, prepare two new HDDs selectedfrom the models specified and tested by HITACHI. Otherwise, the data stored
on the HDDs may be lost.
● When you build a RAID1 system from scratch, use the recovery DVD andinstall the OS from scratch.
● Care must be taken when you build a new RAID 1 system on an existing
RAID1 system. The setup process will completely overwrite the existing RAID
configuration information and you will no longer be able to use the existing
RAID 1 system.
To build a RAID1 system, follow the procedure below.
Note that, when the product is shipped, a RAID1system has been already built, and thefollowing procedure is not necessary.
The screenshots used in the following explanation are just examples. The model name,capacity, and other information about an HDD shown here may be different than those shownin an actual working system.
1. Prepare two new HDDs.
2. Shut down the OS. Turn off the main power to the equipment, and wait for at least one
minute. And then mount the HDDs on drive bays 1 and 2. (See Figure 5.4.4 Installing andRemoving an Hard Disk.)
3. Turn on the power for the equipment. When "Adaptec RAID BIOS" is displayed on themonitor, press Ctrl+A to start the "Adaptec RAID Configuration Utility".

8. RAID1

8.4.2 Recovery from a failure in one HDD

NOTICE● Never remove an HDD when the HDD status lamp of the HDD is OFF. If you do,
the data stored in the HDD gets corrupted.
● Wear cotton gloves when replacing an HDD in order to prevent problems causedby static electricity. If you do not, the data stored on the HDD may get corrupted.
● Make sure you check the correct procedure before you start the work. If you do notfollow the correct procedure, the data stored on the HDD may be lost.
● As a replacement HDD, do not use an HDD previously used in the A model or the
D model. If you do, this equipment may not operate properly or the data on the
HDDs may be lost because of configuration information mismatches or otherreasons.
● Mount an HDD securely. Loose contacts and missing screws may result in a
failure.
● Do not subject an HDD you are mounting and the already mounted HDDs to shock
while replacing an HDD. Otherwise, failure of the equipment may result.
● Until the rebuild is complete, avoid shutting off the power for this equipment or
attaching and detaching HDDs. Otherwise, the data on the HDDs may be lost or a
failure may result.

To recover from a failure in one HDD, follow the procedure below.
For information about how to recover using a backup HDD, see "8.5.2 Recovery Using a
Backup HDD".
(1) If you replace an HDD while the power to the equipment is on
1. Back up the data.
(See "PRECAUTIONS 4. (2) Backing Up Files.")
2. Terminate all running applications.
3. Double-click the hardware status icon on the notification area of the taskbar.

8. RAID1

8.4.5 Recovering a Normal HDD That Has Been Set to Offline by MistakeOn this equipment, the RAID board keeps track of all HDDs that have been set to offline(hereinafter referred to as an "offline HDD") for any reason.
Therefore, an offline HDD cannot be used in the equipment that sets the HDD to offline.
But as an exception, if a normal HDD is set to offline by mistake or if an HDD is set tooffline by the RAS software for evaluation of the equipment, the following action can restore
the offline HDD, and allow it to be used as a new HDD again.

NOTICE● If you apply the recovery method for an offline HDD to an HDD that was set tooffline by something other than the RAS software, the HDD may not berecovered, or even if it is recovered, the HDD may not work properly.
● Use the recovery method for an offline HDD only for the purpose of evaluating
the equipment. If you apply the recovery method for an offline HDD toequipment actually used in the field, for example, a system in normal
operation, malfunctions may result, including data loss.
● If an HDD is automatically set to offline by the equipment, the HDD may
possibly be out of order. Do not apply the recovery method for an offline HDD
to such an HDD.
● An HDD recovered by the recovery method for an offline HDD must not be
used for equipment actually used in the field. If used, malfunctions may result,including data loss.
< NOTICE >When step 7 is complete, the status LED of the offline HDD turns off, but the LED will start flashing red
again after about 30 seconds. Make sure you finish all steps up to step 10 before the LED starts flashing. If the
LED starts flashing red again, executing "Initialize Drives" fails, then you need to go back to step 5 and retry.

1. Shut down the OS. Turn off the main power to the equipment, wait for at least one minute,and remove the normal HDD. Record the drive bay number of the removed HDD.
2. Turn on the power to the equipment while only the offline HDD is connected.
3. When "Adaptec RAID BIOS" is displayed on the monitor, press Ctrl+A. The "Adaptec
RAID Configuration Utility" starts.
4. When the "Adaptec RAID Configuration Utility" starts, select "Array Configuration
Utility", and press Enter. The "Main Menu" is displayed.
5. Confirm that the status LEDs for HDD1 and HDD2 are flashing red while the "MainMenu" is displayed. (It may take about 30 seconds until the status LEDs starts flashing red
after the "Main Menu" is displayed.) Then remove the offline HDD from the HDD drivebay.
6. Wait for about one minute, and then insert the offline HDD back into the original HDD
drive bay.

8.5 Preventive Maintenance8.5.1 Creating a Backup HDD

NOTICE● Wear cotton gloves when replacing an HDD in order to prevent failure causedby static electricity. If you do not, the data stored on the HDD may getcorrupted.
● Make sure you check the correct procedure before you start the work. If you do
not follow the correct procedure, the data stored on the HDD may be lost.
RAID1 is more reliable compared to a system with a conventional configuration.
Nevertheless, the data stored on the HDDs may be lost due to human error or other reasons.
If you create a backup HDD, you can recover from such data loss.
(Note that you can only restore to the point of backup.) We recommend that you prepare abrand-new HDD or another properly prepared HDD for backup and use it to back up the data
periodically. Follow the procedure below, and create a backup HDD.
< NOTICE >・ Make sure you create the backup HDD in drive bay 2.
・ If you want to reuse a previously used backup HDD as a replacement HDD, you must apply "Initialize
Drives" to the used backup HDD. (See steps 3 to 8 described in "8.2.2 Building a RAID1 System".)・When a replacement HDD is installed, its capacity must be the same as the capacity of the HDD1.

1. Shut down the OS. Unplug the plug of the power cord from the outlet, and wait for atleast one minute. Then replace the HDD mounted in drive bay 2 with a brand-new HDD.
(See "5.3.6 Installing and Removing an HDD".)
Make sure you record the drive bay number of the removed HDD.
2. Store the removed HDD in a safety place as a backup HDD.
3. Turn on the power to the equipment. Then the RAID board automatically detects that abrand-new HDD is mounted and starts the rebuild process. Confirm that the HDD2 statuslamp is flashing.
4. The OS starts while the rebuild process is continuing. The time required for the rebuild
process depends on what applications are executed during this period. Therefore,
minimize the number of running applications during the rebuild process. If you do notwant to start the OS, while the messages for system initialization are displayed (during theBIOS memory check), or while the Digital LEDs for Status indication output "C0" after
the equipment turns on, press F2 to launch the BIOS setup menu.
The rebuild process takes about 120 minutes in the case of a 1 TB HDD without a load.
The rebuild process takes about 280 minutes in the case of a 2 TB HDD without a load.

8-35

8. RAID1

5. When the HDD2 status lamp turns off, the rebuild process is complete. Also in the
Hardware status window, confirm that both HDDs are healthy.
If the BIOS setup menu is started at step 4, open the upper menu "Exit", move the cursor
to "Exit Saving Changes", and press Enter. A message "Save configuration changes andexit now?" is displayed. Press Enter to restart the equipment.

8.5.2 Recovery Using a Backup HDD

NOTICE● Wear cotton gloves when replacing an HDD in order to prevent failure causedby static electricity. If you do not, the data stored on the HDD may getcorrupted.
● Make sure you check the correct procedure before you start the work. If you do
not follow the correct procedure, the data stored on the HDD may be lost.
Prepare a backup HDD as well as a brand-new HDD, or HDD to which "Initialize Drives"
has been applied (see "8.2.2 Building RAID1"). Then recover the array by following theprocedure below. When you install and remove an HDD, see "5.3.6 Installing and Removing
an HDD" for the procedure.
< NOTICE >・ Make sure you mount the backup HDD in drive bay 2. If you mount a backup HDD in the wrong
drive bay, rebuild may not start automatically.
・ When a brand-new HDD or an appropriately prepared HDD is installed, its capacity must be thesame as the capacity of the backup HDD.

1. Shut down the OS, and unplug the plug of the power cord from the outlet. If HDDs aremounted, remove both HDDs.
2. Mount a brand-new HDD or an appropriately prepared HDD in drive bay 1.
3. Follow steps 3 to 8 described in "8.2.2 Building a RAID1 System" (to execute"Initialize Drives").
If the following message is displayed at step 4 in "8.2.2 Building a RAID1 System",choose Accept and press Enter.
Configuration change has been detected in the system.
If you reject the configuration change, you will not
be able to modify current configuration. If you accept,
it will be updated to the current configuration.

not follow the correct procedure, the data stored on the HDD may be lost.
● As a replacement HDD, do not use an HDD previously used in the A model orthe D model. If you do, this equipment may not operate properly or the data on
the HDDs may be lost because of configuration information mismatches, orother reasons.
● Do not replace the two HDDs at the same time. If you do, the data getscorrupted.
● When you replace an HDD, make sure that you set the HDD into the offlinemode in the Hardware status window, and then remove that HDD and mountthe replacement HDD. If you mount or remove an HDD when the hardware
status cannot be checked, for example, immediately after the OS starts, afailure may result.
An HDD is a replacement component that must be replaced periodically. (For information about
the recommended replacement cycle, see "APPENDIX HANDLING REPLACEABLECOMPONENTS ".)Follow the procedure below for periodic replacement.
Note: The following is the procedure for replacing the HDD mounted in drive bay 1. When you
replace the HDD mounted in drive bay 2, interpret drive bay 1 as drive bay 2 and the
HDD1 status lamp as the HDD2 status lamp when following the procedure.
(1) If you replace the HDD while the power to the equipment is turn off
1. Back up the data.
2. Shut down the OS. Unplug the plug of the power cord from the outlet, and wait for at least
one minute. Then replace the HDD mounted in drive bay 1 with a replacement HDD. (See"5.3.6 Installing and Removing an HDD".)
3. Turn on the power to the equipment. Then the RAID board automatically detects that the
replacement HDD is mounted and starts the rebuild process. Confirm that the HDD1 statuslamp is flashing.

4. The OS starts while the rebuild process is continuing. The time required for the rebuild
process depends on what applications are executed during this period. Therefore, minimize
the number of running applications during the rebuild process. The rebuild process takes
about 120 minutes in the case of a 1 TB HDD without a load. The rebuild process takes
about 280 minutes in the case of a 2 TB HDD without a load.
If you do not want to start the OS, while the messages for system initialization are displayed(during the BIOS memory check), or while the Digital LEDs for Status indication output"C0" after the equipment turns on, press F2 to launch the BIOS setup menu.
5. When the HDD1 status lamp turns off, the rebuild process is complete. Also, in the
Hardware status window, confirm that both HDDs are healthy. If the BIOS setup menu isstarted at step 4, open the upper menu "Exit", move the cursor to "Exit Saving Changes",and press Enter. A message "Save configuration changes and exit now?" is displayed. Press
Enter to restart the equipment.
(2) If you replace the HDD while the power to the equipment is turn on< NOTICE >You need to have administrator privileges to execute step 3. Log on to the computer using an
administrator account and click OFFLINE. If "User Account Control" (UAC) is enabled, in aconfirmation message, click Yes. The User Account Control window is displayed. Then click
Continue.
Note that if "User Account Control" (UAC) is disabled and a user without administrator privileges
clicks the OFFLINE button, the HDD is not disconnected.

1. Back up the data.
2. Terminate all running applications.
3. Double-click the hardware status icon on the notification area of the taskbar.
The Hardware status window appears. In the Hardware status window, under Drive
bay1, click OFFLINE to set the HDD into the offline mode.

Confirm that the HDD1 status lamp is on. It may take a few tens of seconds for
the HDD1 status lamp to turn on.

4. Execute steps 4 to 7 described in "8.4.2 (1) If you replace a HDD while the power tothe equipment is on" to rebuild the array.

8.5.4 Consistency Check for the Mirror Disk
Follow the procedure below for a consistency check of the data on the HDD. For details about
the consistency check, refer to the HF-W7500 Model 40 RAS FEATURES MANUAL (WIN-630090).
< NOTICE >・ You can execute a consistency check only when both HDDs are in the normal condition.
・ Note that a consistency check takes an extremely long time. (It takes about two hours when theload is minimal.)・ During a consistency check, there are a lot of accesses to the HDD. Consequently, the systemload may increase, and applications may become slow. Do not execute a consistency checkwhen business applications are running.
・ You must have administrator privileges to use the /START option. Execute it using an
administrator account of the computer. If "User Account Control" (UAC) is enabled, start thecommand prompt by clicking Run as administrator, and then execute this command.

1. Start the system, and log on to the system as a member of the Administrators group.
2. Start the command prompt, and execute the following command. When the command is
executed, a confirmation message is displayed to confirm whether to start a consistency
check. Press Y to start a consistency check.
C:\ >raidcheck /STARTThe consistency check process causes high system load.
Applications should be stopped.
Are you sure you want to continue with this process ? [y/n] : y
A start request of consistency check was sent.

APPENDIXHANDLING REPLACEABLE COMPONENTSAPPENDIX HANDLING REPLACEABLE COMPONENTSNOTICEDo not use a replaceable component for longer than the recommended
replacement cycle. If you do, a deteriorating or worn-out component may cause
the equipment to fail.

・As you use a component, it gradually deteriorates and becomes subject to wear and tear. The
following components must be replaced at fixed intervals.
・Replacement of these components is not free of charge.
・The recommended replacement cycle in the following table assumes that the average ambient
temperature of the system unit is 25°C or less.
Note that when the average ambient temperature exceeds 25°C, the replacement cycle may be
shortened in some cases.
