WARNING
l The AC power cord must be connected to a grounded outlet. In case of a short-circuit,
electrical shock or fire may occur.
l Do not use the ArrayMasStor in hot, humid or dusty environments. Usage under such
conditions may result in a short circuit, electrical shock or fire.
l The ArrayMasStor's cover must be securely attached to the chassis. If the cover is not
properly installed, ventilation could be impaired and this may cause a short circuit,
electrical shock or fire.
l Do not block the ventilation opens. Without proper ventilation, the ArrayMasStor will
malfunction or fail.
l Use the supplied AC power cord. In case of a short circuit, electrical shock or fire may
occur.
CAUTION
l Rapid temperature changes may cause condensation of humidity to form on the
ArrayMasStor. Do not use the subsystem where it will not evaporate.
l Do not install the ArrayMasStor near electronic components with strong
electromagnetic fields, such as televisions or loud speakers.
l Turn off the power before moving, connecting or disconnecting the ArrayMasStor.
This will prevent vibrations or mechanical shocks from damaging the hard disk drives
(HDD) and other internal components.
l Do not remove the drive unit during normal operation, as this may cause damage,
malfunction or data loss. The drive unit should be removed when they have failed and
need to be replaced.
l Use the appropriate SCSI host card for ArrayMasStor in accordance with single-ended
or low voltage differential (LVD) SCSI interface. Using the wrong card may damage
the subsystem or cause a malfunction to occur.
l Use only the approved replacement drive unit in the ArrayMasStor. Please see
Appendix D for a list of approved replacement parts.

l Do not turn on and off in a rapid succession manner. Leave at least 15 seconds
between turning on and off. This may avoid damage or malfunction. The HDD
requires about 15 seconds to completely stop after turning off the ArrayMasStor.
l Insert to push the drive unit firmly. A loose connection may damage the
ArrayMasStor or cause it to malfunction.
l Do not turn the ArrayMasStor off by unplugging the AC power cord from the rear
panel. This may result in data loss. The ArrayMasStor’s firmware is designed to
detect the status of the power switch and synchronize the data in the cache and the
drives before shutdown. To control the power from the AC line, send a ‘synchronize
cache’1 command from the host computer to the ArrayMasStor.
l When unplugging the AC power cord, leave one minute further before plugging it
again. This may prevent fuse damage.
IMPORTANT !
l For optimum performance, the total length of the SCSI bus should be as short as
possible. The total cable length must be less than 1.5 m for single-ended mode and
12m for LVD mode.
l A maximum of two host computers can be connected to the ArrayMasStor in a dual
host configuration.
l Set the ArrayMasStor’s UNIX2 C/H/S mode before connecting it to the operating
systems shown below. Changing the UNIX C/H/S mode after installation may cause
data loss.
Solaris3(SPARC) 2.X

l It is strongly recommended that up to two ArrayMasStors be connected to the same
bus in the single-ended SCSI.
l It is strongly recommended that the data be regularly backed up. In RAID levels 1 and
5, the ArrayMasStor will be operative when a drive fails. However, if two or more
drives fail, all of the data may not be recoverable. And, if any other parts of the
ArrayMasStor malfunction, there is possibility of data loss.
l It is strongly recommended that the surface verification check implement before
dynamic data reallocation.
l It is strongly recommended that an interruptible power supply (UPS) be used with the
ArrayMasStor to avoid data loss when the power line is unstable and power outrage
happens.

1 Introduction to the ArrayMasStor J Series
The ArrayMasStor J Series is a compact, high performance, redundant array of independent disks.
The subsystem includes up to four hard disk drives (HDD) and offers high availability and an
excellent data transfer rate. The subsystem is easy to install and use, and has a unique interoperability
feature that allows it to work through a simple SCSI interface and be recognized as a single drive by a
host computer.
1.1 Features
The ArrayMasStor J Series
l Stores a large capacity data securely with excellent performance and data availability.
l Allows a failed drive to replace without interrupting system operation. Data
reconstruction starts automatically upon drive replacement.
l Data reconstruction onto the spare drive starts immediately when a drive fails. (hot spare
mode)
l Improves write performance with large-capacity cache buffer.
l Recognized as a single drive on the SCSI bus. The ‘daisy chained’ SCSI connection can
be extended extremely a large storage capacity.
l Complies with the standard SCSI-3 interface.
l Provides dynamic data reallocation and background surface verification for maximum
system availability.
l Allows mixed RAID levels within the one product.

1.2 About RAID levels
The ArrayMasStor J Series supports three RAID levels, so you can choose the optimal level for your
application. The default setting is RAID Level 5 if at least 3 hard disk drives are online. The default
setting is RAID Level 1 if 2 hard disk drives are online. In the following examples, four drives are
assumed to be online.
IMPORTANT !
All stored data will be erased when the RAID level is
changed. Back-up the data before changing the RAID level.
1.2.1 RAID Level 0
In this level, data is striped over all of the drives in the array. This provides the maximum storage
capacity, since the entire array is used solely for data storage, and the ArrayMasStor’s input/output
performance is maximized because of the drives’ parallel processing ability.
IMPORTANT !
In RAID Level 0, there is no data redundancy. Data will be
lost if a drive fails.
The effective storage capacity of this RAID level is as follows:
(Effective storage capacity) = (Capacity of one drive) x (Number of drives)
This RAID level is suitable for applications that require high performance and the largest available
storage capacity, without the need for data protection.

1.2.3 RAID Level 5
In RAID Level 5, parity data is generated and stored on the equivalent of one drive. If one drive fails,
the lost data can be reconstructed using data recorded on the other drives and the parity data. Parity
data is written on all of the drives in order to avoid performance degradation due to the intensive
access requirements that would result from using a single or specific parity drive.
The effective storage capacity of this RAID level is as follows:
(Effective storage capacity) = (Capacity of one drive) x (Number of drives - 1)
This RAID level is most appropriate when data protection is the primary consideration.

1.3 Mixed RAID Levels
The ArrayMasStor supports mixed RAID levels. This means that the ArrayMasStor can be
configured to handle multiple logical units (LU), and that a different RAID level can be assigned to
each LU. The ArrayMasStor can support up to seven separate LU (0 – 6) and separate RAID levels.
A sample configuration is shown below:

LUN 1 - RAID 1
LUN 2 - RAID 5

LOGICAL DRIVE 1 2 3 SPARE
1.4 Hot Spare Feature
When the hot spare feature is activated, background data recovery onto the spare drive starts
immediately after the failure of an on-line drive. This feature reduces the effective storage capacity of
the ArrayMasStor, since one drive is reserved as a hot spare. However, the hot spare feature improves
the ArrayMasStor’s reliability and its ability to protect data. After the data recovery process is
complete, the ArrayMasStor is redundant (fault tolerant) again.
In the following example, there are four drives in the ArrayMasStor. The hot spare feature is only
available when more than three drives are used.
When one of the on-line drives fails, the data recorded on the failed drive is re-generated and written
onto the spare drive. After the data recovery process is complete, the spare drive takes the place of
failed drive. For example, if drive #3 fails, the hot spare drive (physical drive #4) becomes logical
drive #3.
When the failed drive is replaced, the replacement drive becomes the spare drive.

1.5 Write Back Cache Function
When used in RAID Level 5, the write operation for small data blocks causes a data bottleneck. This
is because, before it can write the new data, the ArrayMasStor must read the old data and parity,
which are needed to generate the new parity5. This phenomenon, which is called the write penalty,
impairs performance when the host computer accesses the ArrayMasStor in a random write pattern.
The ArrayMasStor uses a large buffer as a write-back cache to compensate for the write penalty
problem. When data is acquired into the cache buffer by a ‘write’ command issued by the host
computer, the ArrayMasStor returns a ‘complete’ command to the host computer. The ArrayMasStor
gathers the small amounts of write data to the cache buffer and writes this data onto the drives at one
time.
When shutting down the ArrayMasStor using the power switch on the front panel, the ArrayMasStor‘s
firmware detects the power switch status, flushes the data in the cache to the drives, and then turns off
the power. When powering down from the AC line, a ‘synchronize cache’ command must be sent
from the host computer to the ArrayMasStor before the power is turned off. Failure to use the
‘synchronize cache’ command can result in data loss.
IMPORTANT !
Push Power Switch to turn off except for emergency. Turning
off by pulling out Power Line Cord may cause data loss in the
cache buffer.
Plugging AC power cord can’t be POWER-ON condition of ArrayMasStor J series.
IMPORTANT !
It is strongly recommended that an interruptible power
supply (UPS) be used to avoid data loss when the power
line is unstable and power outrage happens.

This is called “Read Modify Write”.

1.6 Dynamic Data Reallocation
The ArrayMasStor J Series supports dynamic data reallocation, which allows the expansion of the
ArrayMasStor’s capacity by adding new drives without data loss. The additional storage capacity is
assigned a new LUN.
The original data is reallocated to suitable locations, and the parity data (for RAID Level 5) is
automatically regenerated. For RAID Level 1, the mirror data is written alongside the original data
and the original drive information is re-striped over the new drives. RAID Level 0 also offers this
feature, but there is no data redundancy when the re-stripping or reallocation procedure is executed.
Increasing the number of drives allows the same total storage capacity to be accessed faster, because
four (rather than three) drives are concurrently accessing the 40 MB of data in each LUN. Each new
LUN is treated as an individual drive by the host computer, and is easily configured from the
operating system for immediate use.
IMPORTANT !
It is strongly recommended that the surface verification
check implement before dynamic data reallocation.
IMPORTANT !
ArrayMasStor won’t permit to access from the host computer
while carrying out dynamic data reallocation.

3 Installing the ArrayMasStor J Series
First, position the ArrayMasStor J series in stable manner and attach the supplied Front cover.
Then, follow these instructions to connect the ArrayMasStor to a host computer.
Default settings are listed in Appendix C.
CAUTION
Never carry the ArrayMasStor with holding the Front cover
or the handle of Drive unit.
CAUTION
Be sure to attach the Front cover and to let it closed.
3.1 Connecting the Power Line Cord
Plug the supplied AC power cord to the receptacle and outlet. The ArrayMasStor uses a
100V~240VAC universal power supply with automatic voltage detection.
CAUTION
Simply plugging the AC power cord will not mean that the
ArrayMasStor is in POWER-ON condition.
3.2 Connecting the SCSI Cable
Use a SCSI cable, meeting SCSI-2 or SCSI-3 specifications , to connect the ArrayMasStor to the host
computer’s SCSI interface. If the ArrayMasStor is located at the end of the SCSI bus, attach a SCSI
terminator to the unused SCSI connectors on the back of the ArrayMasStor.
IMPORTANT !
For optimum performance, the total length of the SCSI
bus should be as short as possible. For a single-ended
SCSI card, the total cable length must be less than 1.5 m.
3.3 Turning the Power On
Turn the power switch key clockwise to power on the ArrayMasStor. Before switching on the power,
check that all drive units are inserted firmly. Switch on the ArrayMasStor before turning on the host
computer.
Page 25
Advanced Technology and Systems Co., Ltd.

3.4 Setting the Password
The ArrayMasStor has a default password that is used to change the configuration (see Appendix C).
The procedure for changing the password can be found in section 4.9.1., Entering the Password.
3.5 Setting the Time & Date
The clock values in the configuration menu are set to a default value. To change the clock value, use
the CHANGE CONFIG menu and follow the procedure in section 4.8.2, Changing the Date and Time
Setting. Before using the ArrayMasStor, set the internal clock to the local time. The correct local
time is required for proper operation of the background surface verify function.
3.6 Setting the SCSI ID
The SCSI ID should be set before starting the host computer. See section 4.8.3, Changing the SCSI
ID for information about changing the SCSI ID. The ArrayMasStor must be restarted before changes
to the SCSI ID will take effect.
3.7 Setting the Spare Mode and Reconfiguring the LUN
All data will be erased when the spare mode or the LUN settings are changed. As a result, changes to
these settings must be made before creating partitions or formatting the storage area. For information
about setting the spare mode, see section 4.10.1, Add Drive as Hot Spare Drive. After setting the
spare mode and the LUN configuration, restart the ArrayMasStor. The new settings will take effect
after the initialization process is completed.
The spare mode does not need to be set if the default settings are used.
3.8 Formatting
Before using, the ArrayMasStor must be partitioned or formatted so that they will work with the host
computer’s operating system. Partitioning and formatting instructions can be found in your operating
system manuals. In some cases, BIOS, file systems, or operating systems place limitations on the
capacity of a single partition. If this occurs, divide the usable area of the ArrayMasStor into partitions
that conform to the capacity limitations. In general, the format operation provided by some of device
drivers and diagnostic programs is not needed in order to be able to use the ArrayMasStor.
3.9 Connection to a Macintosh
6
The following limitations apply when connecting the ArrayMasStor to a Macintosh computer:
• Supported Machines
CPU : 68040 or Power PC

ArrayMasStor J Series User’s Manual
17
OS : System 7.1 or above
• The drive formatter provided with Apple computers only recognizes drives supplied by Apple
Computer. In order to format the ArrayMasStor for use with a Macintosh, a hard disk formatter
from a third party is necessary. The Hard Disk Tool kit by FWB is recommended.
• The ArrayMasStor does not support blind transfer. Please set the transfer mode to non-blind
transfer.
• Each partition has a maximum capacity of 2GB on a system 7.0 and 4GB on a system 7.5. If the
ArrayMasStor’s capacity exceeds these limitations, the entire storage capacity should be divided
into several smaller partitions.
3.10 Connection to the UNIX Systems
• The UNIX C/H/S mode must be set before the ArrayMasStor is connected to the following
operating systems:
Solaris (SPARC) 2.X
IRIX 5.X
• The configuration file in Sun OS (Solaris 2.5.1/2.6) must be edited to use the LUN.

4.2.7 Double Fault (Failure of two or more drives)
When two or more drives fail, data stored on the ArrayMasStor cannot be reconstructed and some or
all of the data will be permanently lost. To avoid double fault, failed drives should be replaced as
soon as possible.
There are two ways to return to the normal mode.
a) Replace only the first failed drive by following the procedures in section 4.2.8, Forced Data
Reconstruction.
b) During system halt, replace the failed drives by following the procedures in section 4.2.9, System
Halt.
The display indicates that the ArrayMasStor is in degraded mode 2,
which means that two or more drives have failed.
This menu turns off the buzzer. Pressing the select button advances
the display to the stop buzzer menu.

4.2.8 Forced Data Reconstruction
Normally, when two drives fail, it is necessary to save the remaining data onto back-up media (e.g.
tape) and replace the failed drives. If back-up media are unavailable, the ArrayMasStor allows users
to perform forced data reconstruction. During forced data reconstruction, the ArrayMasStor detects
the unrecoverable read errors in the source drives, skips the damaged sector and continues to
reconstruct from the next sector, until the last sector has been reconstructed. The data in the sector or
sectors with unrecoverable errors are either damaged or lost.
When two drives fail, DRIVE X Y FAIL appears on LCD display, where X is the physical number of
the first failed drive. Replace the first failed drive (X) before replacing the second failed drive (Y).
(Note: If the second failed drive (Y) is replaced before the first failed drive (X), the ArrayMasStor
enters system halt mode and the host computer cannot access the data in the ArrayMasStor. If this
happens, swap drives X and Y and then restart the ArrayMasStor.)
After replacing the first failed drive, FORCE RECON appears on the display. This menu appears
when the source drive failed during normal reconstruction mode, without replacement of the first
failed drive. Press the select button to start forced data reconstruction. When the data reconstruction
is complete, the ArrayMasStor enters degrade mode (when only one failed drive is left), or degrade
mode-2 (when more than one failed drives are left), except spare drive.
The display indicates that two drives have failed. Replace the first
failed drive (x), before replacing the second failed drive (y).
The display indicates that the first failed drive has been replaced.
Press the select button to start forced data reconstruction.
Press the select button again to confirm the start of force data
reconstruction. If the cancel button is pressed, the display returns to
the main menu and reconstruction is cancelled.
Press the select button again to confirm the start of forced data
reconstruction.
The display indicates the forced data reconstruction has started, and
indicates the drive that is being reconstructed, and the progress (in
percent) of the reconstruction process. When forced data
reconstruction is complete, the display returns to degraded mode or
degraded mode-2 menu.

4.2.9 System Halt
When an unrecoverable error occurs (due to the replacement of two or more drives, or to the failure of
the RAID controller board), the ArrayMasStor enters system halt mode. In system halt mode, the
ArrayMasStor prevents further data corruption by rejecting SCSI commands from host computer. If a
system halt occurs for reasons other than those stated above, contact your service representative for
assistance.
IMPORTANT !
During initialization all user data is erased.
The display indicates that the ArrayMasStor has entered system halt.
If the buzzer is switched on, it will beep. To stop the buzzer, press
the select button.
To turn off the buzzer, press the select button again. If the cancel
button is pressed, the display returns to the previous menu without
turning off the buzzer.
Initialization erases all error information on the drives and returns
the system to normal mode. However, during initialization all data
is erased.
A password is necessary to start initialization. For instruction on
how to enter the password, see section 4.9.1, Entering the Password.

4.2.12 Surface Check
The Surface Check function prevents a double fault from occurring when an error correcting code
(ECC) fault is encountered while the ArrayMasStor is operating in degraded mode. This function is
not available in RAID Level 0, because the data are not redundant. In RAID Levels 1 and 5, the
surface check scans the drives for ECC faults and fixes these errors by overwriting them with correct
data generated from the mirror or parity data. The ArrayMasStor uses three selectable methods to
check data:
Surface check: This scans the entire data area for ECC faults and reconstructs and overwrites errors.
Parity regeneration: In RAID Level 5, this regenerates each parity block and rewrites it to the drives.
Random Check: This scans random storage areas for ECC faults and fixes the errors.
All of these tests should be performed periodically to ensure data and parity consistency.
From the Change Configuration menu, use the up or down button to
choose the SURFACE CHECK option.
After selecting the SURFACE CHECK option, the ArrayMasStor
immediately checks the entire data storage area.
During the procedure, the progress of the scan is displayed in percent.
When the scan is complete, the display returns to the main menu.
Choose the PARITY CHECK option from the CHECK MODE menu to start
the parity regeneration process. This process begins with the surface check
procedure and is followed by the parity regeneration procedure. This option
is only available if one of the LUNs is set to RAID Level 5.
During the procedure, the progress of the scan is displayed in percent.
When the scan is complete, the display returns to the main menu.
Choosing RANDOM CHECK from the SURFACE CHECK menu
starts the random check procedure.
When random check option is selected, the start time for the check

4.6.5 Write Cache Mode
The Write Cache Mode controls the ArrayMasStor’s controller card
and drive cache. Disabling the write cache mode bypasses the drive
cache and causes data to be written directly to the drives. This
degrades the ArrayMasStor’s performance.
4.6.6 AIX Error Notice Mode
If the ArrayMasStor is used with an RS/6000 machine that uses AIX
operating system, the AIX error notice mode should be turned on.
This will allow the ArrayMasStor to receive logged data through the
AIX “errpt” command. If the ArrayMasStor is used with a non-AIX
operating system, the AIX error notice mode should be turned off.
IMPORTANT !
Turn off the AIX error notice mode when using the
ArrayMasStor with non-AIX operating system. Failure to do
so may cause the ArrayMasStor to malfunction.
4.6.7 UNIX C/H/S Mode
The UNIX C/H/S status is displayed. When the ArrayMasStor is
used with host computers using the UNIX operating system, the
C/H/S mode should be turned on.
4.6.8 Ultra SCSI Mode
When the ultra SCSI mode is turned on, a maximum data transfer rate
of 40MB/second can be achieved. If it is turned off, the maximum
transfer rate is 20MB/s.
4.6.9 Initiator Mode
When the initiator mode is turned on, the ArrayMasStor can copy its
data to another storage device, such as a SCSI drive or another
ArrayMasStor. The new storage device must have a capacity that is
equal to or greater than the ArrayMasStor’s.

When the background surface check is turned on, the ArrayMasStor
automatically performs surface checks. The default setting is on,
with checks starting at 00:00 each Sunday. The execution time is 60
minutes and, for proper operation, the ArrayMasStor’s internal clock
must be set to the correct local time.
The check interval (weekly each Sunday) is displayed. The
ArrayMasStor supports three user-selectable intervals: once, twice
and three times per week.
The start time (00:00) and execution time (60 minutes) are displayed.
4.6.11 DPO/FUA Bit
The DPO/FUA (disable page out/force unit access) is used only
when the host computer’s operating system issues the FUA
command for every read/write command. Use of this command
7
degrades the ArrayMasStor’s performance. To prevent this from
happening, the DPO/FUA bit should be turned off.
IMPORTANT !
Only turn on the DPO/FUA bit if your operating system uses
the force unit accesses command with its read and writes
operations. For additional information, see your operating
system manual.
7
When a FUA read/write command is sent to the ArrayMasStor, the cache is bypassed and the read
and write operations are sent directly to the drives. This results in impaired performance.

4.9.13 Performing Surface Check
The surface check function, which is only available in RAID levels 1 and 5, prevents double faults
from occurring when an error correcting code (ECC) fault is encountered while the ArrayMasStor is
operating in degraded mode. The ArrayMasStor has a function that corrects ECC faults by
overwriting the area containing the fault. The ArrayMasStor uses three methods to check data.
• Surface check: This scans the entire data area for ECC faults and reconstructs and overwrites
errors
• Parity regeneration: In RAID Level 5, this regenerates each parity-block and rewrites it to the
drives
