Section 1. General Description
This
is the preliminary manual for the M2266 manual and is subject to
change without notice.
This section describes the features and configuration of the M2266S/H
intelligent disk drive. This drive is a high-performance, large-capacity, 5
1/4-inch fixed disk drive with an embedded SCSI controller.
The interface between the IDD (Intelligent Disk Drive) and host system is
based on the Small Computer System Interface (SCSI) ANSI standard
(X3.131, 1986.)
The flexibility and expandability of the SCSI, as well as the powerful
command set of the IDD, allow the user to construct a high-performance,
reliable disk subsystem with large storage capacity.
The IDD is available with two different kinds of SCSI bus, based upon
electrical requirements:
M2266S
Single-Ended SCSI
•
M2266H
Also, the IDD is available with the following models based upon data format
at factory shipment. The drives are preformatted at 512 bytes per sector, but
may easily be reformatted in the field to any sector size from 180 to 4128
bytes per sector, in 2-byte increments.
Differential SCSI
Note: Some earlier revisions of the drive have a maximum bytes per sector
of 3808 bytes.

Standard Features
Compactness
Since the SCSI controller circuit is inside the IDD PCA in the standard 5 1/4-
inch fixed disk drive form factor, the IDD is extremely compact. The IDD
can be connected directly to the SCSI bus of the host system.
SCSI/CCS Standard
The IDD provides not only SCSI basic functions but also the following
features:
•
Arbitration
•
Disconnection/Reselection
Data Bus Parity
•
Command set which meets the logical specification of the SCSI CCS
•
(Common Command Set for Direct Access Device) Requirements
(Rev. 4B).
The SCSI commands can manipulate data through logical block addressing
regardless of the physical characteristics of the disk drive. This allows
software to accommodate future expansion of system functions.
High-Speed Data Transfer
The data transfer rate on the SCSI bus is 2.00MB/s maximum, in
asynchronous mode and 4.8 MB/s maximum in synchronous mode. Such a
high data transfer rate on the SCSI bus can be useful with the large capacity
buffer in the IDD.
Notes:
1.
2.
1-2
The maximum data transfer rate in asynchronous mode may be
limited by the response time of the initiator and by the SCSI bus
length.
The maximum data transfer rate in synchronous mode on the
single-ended SCSI bus may be limited by the cable length and
transmission characteristics of the SCSI bus.

M2266S1 H
Continuous Block Processing
The addressing method of data blocks is logical block address. The initiator
can access data by specifying the block number in a logically continuous data
space without regard to the physical structure of the track or of cylinder
boundaries.
The continuous processing of up to 64K blocks in a command can be
achieved, aid the IDD can perform continuous read/write operations when
processing data blocks across track or cylinder boundaries.
256KB Data Buffer
Data is transferred between the SCSI bus and the disk media through the
embedded 256KB data buffer in the IDD.
Since the initiator can control the disconnect/ reconnect timing on the SCSI
bus by specifying the condition of stored data to the data buffer or empty
condition of the data buffer, the initiator can perform the effective
input/output operations by utilizing the high data-transfer capability of the
SCSI bus, regardless of the actual data transfer rate of the disk drive.
Read-Ahead Cache Feature
After executing the READ command, the IDD reads automatically and stores
(prefetches) the subsequent data blocks into the data buffer (Read-Ahead
caching.) This function may be programmed to prefetch data in amounts
from one sector's worth to 256 Kbytes of data.
The high-speed sequential data access can be achieved by transferring the
data from the data buffer without reaccessing the disk in case the subsequent
command requests the prefetched data blocks.
Command Stack Feature
The command stack feature of the IDD corresponds to up to seven initiators.
Therefore, the IDD can accept and stack the input/output command issued
by another initiator even if the IDD is executing another command. The
stacked command is retrieved and executed in stacked order after the
present command has completed execution.
Reserve and Release Functions
The IDD can be accessed exclusively in the multi-host or multi-initiator
environment by using the reserve and release functions.

M2266S/H
Technical Handbook
Error Recovery
The IDD can try to recover from errors in the SCSI bus or the disk drive
using its powerful retry processing. If a recoverable data check occurs, error-
free data can be transferred to the initiator after being corrected in the data
buffer. The initiator software is released from the complicated error
recovery processing by these error recovery functions of the IDD.
Automatic Alternate Block Reassignment
If a defective data block is detected during read or write, the IDD can
automatically reassign its alternate data block.
Programmable Data Block Length
Data can be accessed with a fixed block-length unit. Data block length is
programmable, and can be set during formatting to the most suitable length,
from 180 to 4,128 bytes, with a 2-byte boundary.
Defective Block Slipping
A logical data block can be reallocated in a physical sequence by slipping the
defective data block during formatting. This results in high speed
contiguous data-block processing without a revolution delay due to a
defective data block.
High-Speed Positioning
A rotary voice coil motor achieves fast positioning.
Large Capacity
The unformatted capacity is 1266 MB. Typically, at 512 bytes per sector the
formatted capacity is 1079 MB. A disk subsystem with large capacity can be
constructed that uses space efficiently.
Start/Stop of Spindle Motor
Using the SCSI command, the host system can start and stop the spindle
motor.
Diagnosis
The IDD has a diagnostic capability that checks internal controller functions
and drive operations to facilitate testing and repair.

Low Power Consumption
By using highly-integrated LSI components, the power consumption of the
IDD is very low, enabling use of the unit in a wide range of ambient
temperatures between 5°C and 45°C.
Low Noise and Low Vibration
The IDD is quiet, running at approximately 45 dB (A-scale weighting) even
during seek, making it ideal for office use. The IDD has rubber vibration
isolators, which minimize the transfer of vibration.
Hardware Structure
Figure 1.1 shows the outer view of the IDD. The IDD consists of a disk
enclosure (DE), a read/write preamplifier PCA, a controller PCA, and
mounting brackets.
The DE is completely sealed and consists of disks, heads, the spindle motor,
the actuator, the recirculation filter, the breather filter, the cover, and the
base.

Technical Handbook
Disks
The Winchester-type disks have an outer diameter of 130 mm (5.12 inches)
and an inner diameter of 40 mm (1.57 inches). The disks are good for at least
10,000 contact starts and stops.
The IDD uses the following number of disks:
M2266: 8 disks
Heads
The Whitney-type CSS (contact start/stop) heads are in contact with the
disks when the disks are not rotating, and automatically float when the
rotation reaches nominal speed.
Spindle Motor
The disks are turned by a direct-drive DC motor. The motor turns at 3600
rpm, ±0.2%. This precision is achieved through a feedback circuit which
includes Hall-effect elements mounted in the motor assembly.
Actuator
The actuator, which uses a rotary voice coil motor (VCM), consumes little
power and generates little heat. The head assembly on the tip of the actuator
arm is controlled by electrical feedback from servo information read-out
through the servo head.
Servo information is used as a control signal activating the actuator. It is
used as track crossing information in positioning, and track following
information during data write/read. The actuator positions heads on the
innermost landing zones over the disk when the power is off or the spindle
motor is stopped.
Air Circulation
The heads, disks, and actuator are sealed inside a disk enclosure (DE) to keep
out dust and other pollutants.
The DE has a closed-loop air recirculation system. Using the movement of
the rotating disks, air is continuously cycled through a filter. This filter will
1-6

Fujitsu America, Inc.
Page 17
Technical Handbook
M2266S/H
trap any dust generated inside the enclosure and keep the air inside the DE
contaminant-free. To prevent negative pressure in the vicinity of the
spindle when the disks begin rotating, a breather filter is attached. The
breather filter also equalizes the internal air pressure with the atmospheric
pressure due to surrounding temperature changes.
Read/Write Circuit
The read/write circuit uses LSIs and head ICs to prevent errors caused by
external noise, thus increasing reliability.
Controller Circuit
The controller circuit uses LSIs to increase reliability and uses a high-speed
Micro-Processing Unit (MPU) to increase the performance of the SCSI
controller.
System Configuration
Figure 1.2 shows the system configuration. The IDDs are connected to the
SCSI bus of host systems and are always operated as target. The IDDs
perform input/output operations as specified by the SCSI devices that
operate as initiators.

SCSI Bus Configuration
Up to eight SCSI devices can be connected to the SCSI bus, with any
combination of the SCSI devices operating as initiators and operating as
targets.
For example, the system can be configured as a multi-host system on which
multiple host computers that operate as initiators are connected through the
SCSI bus.
Using the disconnect/reconnect function, concurrent input/output
processing is possible on multi-SCSI devices.
Peripheral Device Addressing
Each SCSI device on the bus has its own unique address (the SCSI ID
number shown in Figure 1.2). For input/output operations, a peripheral
device attached to the SCSI bus and operating as the target is addressed as the
logical unit. A unique address or logical unit number (LUN) is assigned to
each logical unit.
The initiator selects one SCSI device by specifying the SCSI ID, and then
specifies the LUN to select the peripheral device for input/output
operations.
When the IDD is constructed so that the whole volume of disk drives is a
single logical unit, the selectable SCSI ID and LUN are as follows:
•
SCSI ID: Jumper selectable from 0 to 7
•
LUN: 0 (fixed)
Model/Part Number Cross References
Each model has a different data format, front panel, and mounting-screw
type. Table 1.1 shows the IDD model names and part numbers. To change
the data format, reinitialize the drive on your system.

Section 2. Installation Requirements
Introduction
Installation of the M2266S/H disk drive is a two-part process:
•
Mechanical and electrical installation of the hardware
•
Performance of the software procedures needed to bring the device to
operational readiness.
This section contains information on the requirements for hardware

Mounting Frame Structure
The disk enclosure (DE) of the IDD serves as a signal ground (SC) and is
insulated from the mounting frame. As this insulation is maintained after
the IDD is mounted in the system, the following precautions must be
followed:
Note:
Generally, SC and FG (frame ground) are connected at one point in the
system enclosure. To maintain insulation when mounting the IDD:
Use the frame with an embossed structure to avoid contact between
(a)
the DE base and FG.
As shown in Figure 2.6, the inward projection of the screw from the

Sequential Starting of Spindle Motors
After power is turned on to the IDD, a large amount of current flows in the
+12 VDC line as the spindle motor rotation starts. Therefore, if more than
one IDD is used, the spindle motors should be started sequentially using one
of the following procedures to prevent overload of the power supply unit.
For information on setting spindle motor start control mode, see Setting
Terminals" in section 3.
Issue START commands at 20-second intervals to start the spindle
a.
motors.
b.
Turn on the +12 VDC power in the power supply unit at 20-second
intervals to start the spindle motors sequentially.
Power Supply to SCSI Terminating Resistor
If power for the terminating resistor is supplied from the IDD to other SCSI
devices through the SCSI bus, the current-carrying capacity of the +5 VDC
power supply line to the IDD must be designed with consideration given to
an increase of up to 900 mA for the M2266S or up to 600
mA
for the
M2266H.
The method of supplying power to the terminating resistor is shown in
Figure 2.12.

Section 4. Software Installation
Introduction
Due to the vast array of computer types, controllers, device configurations,
and software utilities in use within small business systems, it is impossible
to give specific installation instructions for each computer type in which the
drive may be installed. There is no generic installation description that
would apply in all cases.
Instead, this section presents basic principles for installing the M2266S/H
disk drive into the most frequently used system: an IBM Personal
Computer or PC-clone, using the PC DOS or MS DOS operating system.
Preparation of the Hard Disk for DOS Applications
Definition of Drive Type
First define the hard drive as "zero",or, "not installed".
Basic Steps for Software Installation
Software installation on the M2266S/H drive involves partitioning, and
high-level formatting. It requires the following steps:
Step 1: Boot DOS, and then run the DEBUG program. At the DEBUG
prompt (" — "), type g=c800:5 to access the BIOS-level formatter.
(Note: The manufacturer of the controller may specify a different
segment and offset location to access the low-level formatter, or
may provide standalone installation software.)
Drive Partitioning
With a DOS version of 3.3 or lower, the maximum drive capacity is 32 MB.
Therefore, multiple drive partitions (C:, D:, E:, . . Z:) of 32 MB or less must
be created. (See step 3 below.) Definition of larger partition size requires
either DOS 4.0x or a third-party software package such as Disk Manager®
from Ontrack Systems, Inc.
Fujitsu America, Inc.
FS810125-01 . . . A
4-1
Page 32
M2266S/H
Technical Handbook
Step 2: Run the software to create the partitions required by your unique
configuration. (This software is either the FDISK program or one
of the third-party software packages mentioned above.) Then boot
the system again to save the partitions.
Step 3: To perform high-level (or DOS-level) formatting of the partitions,
use the DOS FORMAT command or follow the on-screen
instructions for a third-party software package. If using the
FORMAT command, enter it at the A: prompt as follows:
FORMAT d:/s

the drive and preparing the drive to receive data.

Notes:
I. Some signals are assigned on both pins CN3 and CN9.
When no external operator panel is connected to the IDD, CN3 and
2.
CN9 are used for setting the terminal of the SCSI ID, etc. (see Setting
Terminals' in section 3) When the IDD is shipped from the factory,
the short plugs are mounted between all even numbered and odd
numbered pins of CN9 and no short plug is mounted on CN3.
When the external operator panel is connected to CN3 or CN9, pay
3.
attention to the following items.
CN3 and CN9 are physically interchangeable. The external
•
operator panel can be connected to either one.
When the external operator panel is connected to CN9, all short
•
plugs on CN9 must be removed. However, pins on CN3
corresponding to the signal set on the external operator panel
must be opened. When there is a signal not set on the external
operator panel, the state of that signal must be set on CN3 using
the short plug. The removed short plug from CN9 can be used for
setting the state.
When the external operator panel is connected to CN3, the short
•
plug on CN9 corresponding to the signal set on the external
operator panel must be removed. When there is a signal not set
on the external operator panel, the state of that signal must be set
on CN9 using the short plug.
Connection Requirements
This section discusses the connections required when installing the drive.
SCSI Cable
All SCSI devices on one bus are daisy-chained with an SCSI cable. A
terminating resistor must be mounted in the SCSI device at each end of the
SCSI cable.
2-16
FS810125-0I . . . A
Fujitsu America, Inc.
Page 42
Technical Handbook
M2266S1H
Since an SCSI terminating resistor module is mounted in the IDD on
shipment, it must be removed when the IDD is not connected at either end
of the SCSI cable. Also, a method for supplying power to the terminating
resistor must be selected with the setting terminal on the IDD. For further
details, see "Setting Terminals" in section 3.
The maximum number of SCSI devices that can be connected to the SCSI
bus is 8, including the host adaptor, IDD, and other SCSI equipment.
The connector socket for the SCSI cable must be an unshielded 50-contact
socket which has two rows of 25 contacts spaced at 2.54 mm (0.1 inch) apart.
It should also have a key way to prevent insertion in the wrong direction
(bump type connector). (See Figure 2.16).

The maximum length of the SCSI cable is as follows. If more than one SCSI
device is connected, the total cable length must not exceed the following:
•
6 m for single-ended type SCSI
25 m for differential type SCSI
•
The use of a 25-pair twisted cable satisfying the following requirements is
recommended.
Single-Ended Type
Conductor Size: 28 AWG (American Wire Guage) or bigger
Characteristics impedance: 100 to 132
Differential Type
Conductor Size: 28 AWG or bigger
Characteristic impedance: 100 to 122 0
Each pair of wires in the 25-pair twisted cable must be connected to pins n
and n+1 (where n is an odd number) on the interface connector. Cables
having an identical impedance must be used on the same SCSI bus to reduce
signal reflection and maintain transmission characteristics.
When an SCSI device is connected to the SCSI cable (except at either end of
the cable), connection to the SCSI connector must be at a branch point of the
cable. If an SCSI device is connected to one end of the SCSI bus, no cable
should be connected after the last SCSI device, except when the cable has a
terminating resistor. (See Figure 2.20.)

DC Ground
A DC ground cable may or may be installed depending on the system
requirements (system installation environment, cabinet structure, power
supply system). This cable is generally connected to the ground of the power
supply unit. Connection between more than one IDD may be in a daisy
chain.
External Operator Panel
The external operator panel is installed only when required for the system.
If it is unnecessary, pins 1 to 4 of CN7 connector for the external operator
panel on the IDD must be opened. Also, necessary features must be set on
CN3 or CN9 using the short plug. (See 'Setting Terminals in section 3.)
Figure 2.21 shows a recommended circuit for the external operator panel.
Since the external operator panel is not provided as an option, the user
must fabricate this panel, referring to the recommendation if necessary.
Note:
Necessary switches and LEDs for the system can be provided on the
external operator panel by referring to the recommended circuit shown
in Figure 2.21.
When there is no signal set for the external operator panel, the signal
must be set on CN3 (or on CN9) using the short plug. The CN3 or CN9
pins corresponding to the signal must be opened. For details, see
"Connectors" in this section and Setting Terminals" in section 3.

switches and plugs, mount drives, connect cables, confirm drive operations
after installation, prepare the drives for use, and remove the drives.
Notes on Handling Drives
General Notes
To avoid damage to the drive, do not allow vibration or shocks
•
exceeding the values defined in the standard. Be especially careful
during unpacking.
Do not leave the drive in a dirty or contaminated environment.
•
Since static discharge may destroy the CMOS semiconductors in the
•
drive, use an antistatic mat after unpacking, and ground yourself when
handling the drive.
Hold the DE. or mounting frame when handling the drive. Do not touch
•
PCAs, except when setting switches.
Unpacking
Use a flat work area. Be sure that the "This Side Up" sign is up. Handle
•
the drive of soft material such as a rubber mat, not on hard material such
as a desk. Handle the drive gently at all times.
Do not remove the sealing label or cover of the DE and screws.
•
Installation
While power is turned on, do not connect or disconnect connectors or
•
change terminals except CN3 and CN9.
Do not move the drive when power is turned on or until the drive has
•
been completely stopped for 15 seconds after the power is turned off.

M2266S/H
Technical Handbook
Packing
Store the drive in an antistatic vinyl bag with a dessicant (silica gel).
•
It is recommended that you use the same cushions and packages as those
•
used at delivery. If those cannot be used, use a package with shock
absorption so that the drive is free from direct shocks. In this case, fully
protect the PCAs and interface connectors so that they are not damaged.
Indicate "This Side Up' and "Handle With Care" on the outside of the
•
package so that it is not turned over.
Storage
Provide vapor-proof packaging for storage.
•
The storage environment must satisfy the requirements specified in
•
Table 5.3 (Environmental Specifications).
To avoid condensation, avoid rapid changes in temperature.
Connections
Figure 3 1 shows examples of connections between the host system and the
IDD. Up to eight devices, including the host adapter, IDD, and other SCSI
devices can be connected to the SCSI bus in arbitrary combinations. Install a
terminating resistor on the host adaptor and on either the last device in the
chain or at the end of the cable.
See Connectors' in section 2 for the cable connection requirements and
power-cable connections.

Notes:
1.
This setting does not affect asynchronous mode transfer.
When synchronous mode transfer request is disabled, the IDD
2.
operates as follows.
•
When the SYNCHRONOUS DATA TRANSFER REQUEST
message is sent from the INIT, the IDD replys to that message and
the DATA IN and the DATA OUT phases of the SCSI bus can be
executed in synchronous mode.
•
The IDD does not send the SYNCHRONOUS DATA TRANSFER
REQUEST message to the INIT.
3. The maximum data transfer rate in synchronous mode is determined
when the SYNCHRONOUS DATA TRANSFER REQUEST message is
exchanged between the IDD and INIT.
3-12
P5810125-01 . . . A
Fujitsu America, Inc.
Page 60
Technical Handbook
M2266S/H
The INIT must determine the parameter sent to the IDD when the
message is exchanged in consideration of the signal transfer
characteristics of the system SCSI bus and the data reception capacity
of the INIT.
The IDD can transfer up to 4.8 MB/s in synchronous mode. However,
since the configuration of the SCSI bus and its transfer characteristics
differ depending on the system, the maximun transfer rate in which
data can be transferred in a stable condition must be determined for
each system.
4.
When 3 to 4.8 MB/s synchronous mode transfer is disabled with this
terminal, the IDD suppresses the data transfer rate to 2.67 MB/s or less
when the SYNCHRONOUS DATA TRANSFER REQUEST message is
exchanged. When 3 to 4.8 MB/s synchronous mode transfer is
enabled, up to 4.8 MB/s of data can be transferred.
At any rate, the maximum data transfer rate determined when the
message is exchanged does not exceed the value in the parameter of
the SYNCHRONOUS DATA TRANSFER REQUEST message
declared by the initiator. Therefore, when the initiator declares the
parameter within the allowable scope of the system, 3 to 4.8 MB/s
synchronous mode transfer is enabled with this plug.
For reference, the IDD data transfer rate in synchronous mode and the
5.
restrictions on the system configuration of the SCSI bus are shown
below.
Remarks:
The following values are rough standards. The values must be
evaluated for each system.

SCSI Terminating Resistor
The SCSI terminating resistor module is installed in the IDD when the IDD
is shipped from the factory. See Figure 3.2 and 3.3 for installation positions.
The terminating resistor module is mounted in a socket and must be
processed in one of the following ways:
•
When connecting the IDD to either end of the SCSI cable, do not remove
the terminating resistor module.
When connecting the IDD to a position not at the end of the SCSI cable,
•
remove the terminating resistor modules. For the M22665, there is one
module. For the M2266H, there are three modules.
Notes:
When removing the terminating resistor module, be careful not to
1.
damage the resistor-module pins, mount socket, and contiguous parts.
When mounting the terminating resistor module, check the mounting
2.
direction and whether the module is fixed. See Figures 3.6 and 3.7.

Mounting Drives
Before mounting a drive in the subsystem cabinet, check the setting of
terminals and of the SCSI terminating resistor.
Mounting Procedures
Since mounting procedures depend on the system cabinet structure, the
procedures may vary according to the specific requirements of each system.
The following steps describe the most common mounting method.
1.
If the system has an external operator panel, it may be difficult to access
the connector after the drive is mounted on the system cabinet. To
avoid a problem, connect the external operator panel cable before
mounting the drive.
2.
Fix the drive in the system cabinet with four mounting screws as
follows:
The drive has eight mounting holes (both sides: 2 X 2, bottom: X4). Fix
the drive by using four mounting holes of both sides or the bottom.
Use mounting screws whose lengths inside the drive-mounting frame
are 4 mm or less when the screws are tightened. (See Figure 2.6.)
When mounting the drive, be careful not to damage parts on the PCAs.
Check that the DE (signal ground) does not touch the system cabinet
3.
chassis (frame ground). There must be a 3.5 mm or greater space
between the DE and the chassis. (See Figure 2.6.)
Connecting Cables
Connect the IDD to the system with the following cables. See section 3 for
further details of the IDD connector positions and connecting cables.
•
Power cable
•
SCSI cable
DC ground cable (if required)
•
•
External operator panel cable (if required)
The general procedures and notes on connecting cables are described below.
Especially, pay attention to the insertion direction of each cable connector.
Fujitsu America, Inc.
FS810125-01 . . . A
3-19
Page 67
M2266S/H
Technical Handbook
Warning:
To avoid possible electrocution, be sure that system power is off before
connecting or disconnecting cables. Do not connect or disconnect cables
when power is on.
Connect the DC ground cable, if required to decrease ground noise.
1.
2.
Connect the power cable.
3.
Connect the external operator panel, if required for the system.
4.
Connect the SCSI cable.
5.
Fix the cables so that they do not touch the DE and PCAs, or so that the
smooth flow of the cooling air in the system cabinet is assured.
Note:
Be careful of the insertion directions of the SCSI connectors. With the
system in which the terminating resistor power is supplied by means of
the SCSI cable, if the power is turned on, the over-current protection
fuse of the terminating resistor power supplier may be blown or the
cable may be burnt if over-current protection is not provided.
Confirming Operations after Installation
This section describes expected operation after power is turned on and areas
to check if you have problems during installation. These procedures apply
to the default setting of motor-start mode; that is, the spindle motor starts
when power is turned on. If you have set the condition to cause the motor
to start with the START command, then the text that follows assumes that
the START command from the interface has been issued.
Expected Operation at Power-on
•
When power is turned on, the IDD executes initial self-diagnosis.
•
If an error is detected in the initial self-diagnosis, the LED on the front
panel blinks. The spindle motor may or may not start rotating in this
stage.

•
The factory default condition is to light the LED display when the IDD
makes connection with the SCSI bus. The LED on the front panel
remains off. When the initiator accesses the IDD by means of the SCSI
bus, the LED lights. However, the disk drive enters the READY state in
20 seconds after power is turned on. Then the IDD reads system
information from the system space on the disk.
Note:
If you have changed the factory default to cause the LED to light at
READY status, the LED on the front panel lights 20 seconds after power
is turned on.
Installation Checklist
If operational problems occur at installation, check the following items:
Are cables mounted correctly?
•
•
Are power and voltages supplied correctly? Measure them at the IDD
power-connection position.
•
Is each terminal setting correct? Note that the initial operation depends
on the setting of the motor-start mode and of the LED display mode.
•
If an error is detected in initial self-diagnosis, the LED on the front panel
blinks. In this case, it is recommended that you issue the REQUEST
SENSE command from the host system to obtain sense data for error
analysis.
Notes:
1.
When you have changed the factory default for LED display to "READY
status," the LED is turned off while the drive continues the seek
operations. However, since the LED is turned off for only one blink, the
LED may seem to be turned on and off or not to be turned off at all.
2.
When the LED display has been left at the factory default of "in
connection with the SCSI bus," the LED on the front panel lights only
when the IDD is connected to the SCSI bus. However, in some
commands or when disconnection in is enabled, the lighting time is
only an instant! Therefore, it seems that the LED blinks or that the LED
remains off.

3. Since the IDD has the automatic readjustment function of
positioning(seek) control, it automatically executes the adjustment
operations with seek at specific intervals from power on (first
adjustment: 2 minutes after power on). When the LED display
requirements are set to "READY status," the LED on the front panel
blinks during the adjustment. This does not indicate a drive error.
Initializing the drive
Since the disk drive is formatted with a specific (default) data format for
each model (part number) when shipped from the factory, the disk may not
need to be low-level formatted (initialized) when it is installed in the
system.
However, to set data attributes different from the default format, the disk
must be reformatted according to the instructions below.
1. Connect the IDD to be reformatted to the system.
2.
If it is necessary to change the sector size (data block length), issue a
MODE SELECT command that specifies the new data block length, as
shown in Figure 3.7 below.

Section 6. Troubleshooting
Component-level troubleshooting of M2266 series drives is not practical or
cost effective. This section provides information for troubleshooting to the
subassembly level only.
Begin troubleshooting by looking at the checklist below to isolate problems
external to the drive. If the problem does appear to be in the drive, then run
the self test program, which this section describes in some detail.
If you need to trace the problem on the SCSI bus, refer to Tables 6.3 and 6.4 at
the end of this section, which show the signals for both the differential and
single-ended SCSI buses.
If you cannot resolve the problem, contact the dealer or distributor who sold
the product for further assistance. If you need to contact Fujitsu Customer
Service, refer to the section Maintenance Information' for telephone
numbers and a description of the information you should prepare.
Additional information may be obtained from the Fujitsu America Bulletin
Board system.
Troubleshooting checklist
•
Are the system cables in good condition and correctly connected?
•
Are the connectors turned the right way and properly seated?
•
Are the bus terminations correctly installed?
•
Are the drive jumpers set correctly?
Are the power supply voltage levels and ripple voltages within tolerance
•
as measured at the drive connector?
Is the host adaptor correctly configured and does it pass its own
•
diagnostic tests?
•
Has the software installation procedure been performed accurately and
completely?

Diagnostics
Self-Diagnostics
The IDD has the following self-diagnostic functions that check the basic
operations of the IDD.
•
Initial self-diagnostics
Offline self-diagnostics (enabled through a setting terminal)
•
•
Online self-diagnostics (enabled through the SEND DIAGNOSTIC
command)
Table 7.1 lists the contents of the tests performed by the self-diagnostics. For
a general check of the IDD including the operations of the host system and
interface, use a test program that runs on the host system. See Test
Programs in this section.

The items that follow briefly describe the diagnostic functions.
a. Hardware Function Test
This test checks the basic operation of the controller and contains the
following tests:
•
EPROM where microcode is stored
•
Peripheral circuits of microprocessor (MPU)
•
Memory (RAM)
•
Data buffer
b.
Seek Test
This test checks the positioning operation of the disk drive using several
seek modes (2-points seek, 1-position sequential seek, etc.) The
positioning operation is checked by confirming the physical address
information . The test reads the ID field from the data block on track 0
of the target cylinder after completion of the seek operation to the target
cylinder.
c.
Write/Read Test
This test checks the write/read function, using the CE space of the disk
drive. It runs two types of diagnostic patterns: repeating
X'BBBA645A27BB', and repeating X'OO'. After writing the diagnostic
pattern into all logical data blocks in the CE space, the test reads the data
block and then compares the data pattern to confirm that writing and
reading operations are valid.
Initial Self-Diagnostics
When power is turned on, the initial self-diagnostics run on the IDD. These
diagnostics check the basic operation of the hardware functions. If an error is
detected, the LED on the drive front panel blinks.
Offline Self-Diagnostics (Setting Terminal)
When the diagnostic mode is set on the terminal CN3/CN9 (by setting the
plug between pins 1 and 2 open), the IDD executes the hardware function
test, seek (positioning) test and the data write/read test of the CE space as self
diagnostics.

Technical Handbook
If commands received from the SCSI bus are being executed or stacked
before the diagnostic mode is set, the self-diagnostics are stared after all
command execution is terminated.
While the diagnostic mode is set, the self-diagnostics are repeated in the
following sequence: hardware function test, seek test, write/read test, as
long as the error is undetected. While the diagnostic mode is set, the IDD
does not reply to the SCSI bus.
Online Self-Diagnostics (SEND DIAGNOSTIC Command)
The INIT can make the IDD execute self-diagnostics by issuing the SEND
DIAGNOSTIC command.
The INIT specifies the execution of self diagnostics by setting 1 for the
Selftest bit on the CDB in the SEND DIAGNOSTIC command and specifies
the test contents with the Unitoff bit.
When the specified self-diagnostics end normally, the IDD posts GOOD
status.
When an error is detected by the self-diagnostics, the IDD terminates the
SEND DIAGNOSTIC command with the CHECK CONDITION status. At
this time, only when an error is detected in the hardware function test, the
LED on the front panel of the disk drive blinks.
Test Programs
The self-diagnostics check the basic operations of the IDD itself. However, to
check general operations such as the host system and interface operations in
a status similar to the normal operation status, a test program that runs on
the host system must be used.
The structure and functions of the test program depend on the user system
requirements. Generally, it is recommended that you provide a general
input/output test program that includes SCSI devices connected to the SCSI
bus and input/output devices on other I/O ports.
To test the IDD functions generally, include the following tests:
•
Interface (SCSI Bus) Test
Basic Operation Test
•
•
Random/Sequential Read Test
•
Write/Read Test
