CHAPTER 1 General Description 1.1 Standard Features 1.2 Hardware Structure 1.3 System Configuration This chapter describes the feature and configuration of the MBA3xxxRC. The HDDs are high performance large capacity 3.5-inch hard disk drives with an embedded Serial Attached SCSI (SAS) controller. The interface used to connect the HDDs to the host system complies with ANSI T10/1601-D Serial Attached SCSI-1.1 (SAS-1.1), which covers items ranging from SAS physical layers to SCSI command protocols.
General Description (4) Dual SAS port support The HDDs have two pairs of driver and receiver set (PHY) for the SAS to support dual SAS port connection. On the HDDs, Primary and Secondary Ports on SAS plug connector (2 physical links plus power connections) are used for SAS port connection. (5) High-speed data transfer The maximum data-transfer speed on the SAS is 300.0 MB/s.
1.1 Standard Features (9) Command queuing feature The HDDs can queue maximum 128 commands, and optimizes the issuing order of queued commands by the reordering function. This feature realizes the high speed processing. (10) Reserve and release functions The HDDs can be accessed exclusively in the multi-host or multi-initiator environment by using the reserve and release functions. (11) Error recovery The HDDs can try to recover from errors in the HDD using its powerful retry processing.
General Description (16) Large capacity A large capacity can be obtained from the HDDs by dividing all cylinders into several partitions and changing the recording density on each partition (constant density recording). The disk subsystem with large capacity can be constructed in the good space efficiency. (17) Start/Stop of spindle motor Using the SAS primitive or the SCSI command, the host system can start and stop the spindle motor.
1.2 Hardware Structure 1.2 Hardware Structure The HDDs have a disk enclosure (DE) and a printed circuit board assembly (PCBA). The DE includes heads on an actuator and disks on a spindle motor mounted on the DE. The PCBA includes a read/write circuit and a controller circuit. (1) Disks The disks have an outer diameter of 70 mm (2.8 inch). (2) Heads The heads have MR (Magnet – Resistive) read element Ramp Load type slider. (3) Spindle motor The disks are rotated by a direct-drive hall-less DC motor.
General Description 1.3 System Configuration For the Serial Attached SCSI, the ANSI standard defines Point-to-Point technology. Figure 1.1 and Figure 1.2 give examples of the SAS system configuration. Figure 1.1 Figure 1.2 (1) Example of SAS system configuration (Dual port internal cabled environment) Example of SAS system configuration (Dual port internal backplane environment) Port addressing Every device connected with the SAS protocol has a unique address (SAS address).

2.1 Hardware Specifications Note: The MTBF is defined as: Operating time (hours) at all field sites MTBF = The number of equipment failures from all field sites Failure of the equipment means failure that requires repair, adjustments, or replacement. Mishandling by the operator, failures due to bad environmental conditions, power trouble, host system trouble, cable failures, or other failures not caused by the equipment are not considered.
Specifications (4) Data security at power failure Integrity of the data on the disk is guaranteed against all forms of DC power failure except on blocks where a write operation is being performed. The above does not applied to formatting disks or assigning alternate blocks.
CHAPTER 3 Data Format 3.1 Data Space 3.2 Logical Data Block Addressing 3.3 Defect Management This chapter explains data space definition, logical data block addressing, and defect management on the HDDs. 3.1 Data Space The HDDs manage the entire data storage area divided into the following three data spaces.
Data Format Note: Spare sectors on the last track in each cell are not necessarily placed at the end of the track because of a track skew or a cylinder skew. (Details are explained in Subsection 3.1.3) Figure 3.1 Cylinder configuration Apart from the above logical configuration, the HDDs intend to increase the storage capacity by dividing all cylinders into several zones and changing a recording density of each zone.
3.1 Data Space (1) User space The user space is a storage area for user data. The data format on the user space (the length of data block and the number of data blocks) can be specified with the MODE SELECT or MODE SELECT EXTENDED command. The user can also specify the number of logical data blocks to be placed in the user space with the MODE SELECT or MODE SELECT EXTENDED command.
Data Format 3.1.2 Alternate spare area The alternate spare area consists of the last track of each cell in the user space and an alternate cylinder allocated to the last 10 cylinders of the last zone in the user space. The spare area in each cell is placed at the end of the last track as shown in Figure 3.2. These spare sectors are located in the end of the track logically, not necessarily located at the end physically because of track skew or cylinder skew. (Details are explained on Subsection 3.1.3.
3.1 Data Space 3.1.3 Track format (1) Physical sector allocation Figure 3.4 shows the allocation of the physical sectors in a track. The length in bytes of each physical sector and the number of sectors per track vary depending on the logical data block length. The unused area (G4) exists at the end of the track in formats with most logical data block lengths. The interval of the sector pulse (length of the physical sector) is decided by the HDDs internal free running clock frequency.
Data Format Track skew Head Track skew Head skew Head Leading logical sector in head p+1 Figure 3.5 Track skew/head skew The number of physical sectors (track skew factor and head skew factor) corresponding to the skew time varies depending on the logical data block length because the track skew and the head skew are managed for individual sectors.
3.1 Data Space Each sector on the track consists of the following fields: (1) Gaps (G1, G2, G3) No pattern is written on the gap field. (2) PLO Sync In this field, pattern X'00' is written. (3) Sync Mark (SM1, SM2) In this field, special pattern is written. This special pattern indicates the beginning of the data field. (4) Data field (DATA1-DATA4) User data is stored in the data field of the sector.
Data Format 3.1.5 Format capacity The size of the usable area for storing user data on the HDDs (format capacity) varies according to the logical data block or the size of the spare sector area. Table 3.1 lists examples of the format capacity when the typical logical data block length and the default spare area are used. The following is the general formula to calculate the format capacity.
3.2 Logical Data Block Addressing (1) Block address of user space The logical data block address number is consecutively assigned to all of the data blocks in the user space starting with 0 to the first data block. The HDDs treat sector 0, track 0, cylinder 0 as the first logical data block. The data block is allocated in ascending order of addresses in the following sequence (refer to Figure 3.5): 1) Logical data blocks are assigned in ascending order of sector number in the same track.
Data Format 3.3 Defect Management 3.3.1 Defect list Information of the defect location on the disk is managed by the defect list. The following are defect lists which the HDDs manage. • P list (Primary defect list): This list consists of defect location information available at the HDD shipment and is recorded in a system space. The defects in this list are permanent, so the initiator must execute the alternate block allocation using this list when initializing the disk.
3.3 Defect Management (1) Alternate block allocation during FORMAT UNIT command execution When the FORMAT UNIT command is specified, the allocation of the alternate block to those defective sectors included in the defect list (P, G, or D) is continued until all spare sectors in the same cell are used up. When they are used up, unused spare sectors in the alternate cylinder are allocated to the defective sectors that follow the sector by means of alternate sector treatment. Figure 3.
Data Format *1 (2) Certification is permitted when DCRT flag is cleared (DCRT flag=0) in FORMAT UNIT command. The HDDs check all initialized logical data blocks by reading them out after the above alternate block allocation is made to initialize (format) the disk. Alternate block allocation by REASSIGN BLOCKS command When the REASSIGN BLOCKS command is specified, the alternate block is allocated to the defective logical data block specified by the initiator by means of alternate sector treatment.
3.3 Defect Management (3) Automatic alternate block allocation • Automatic alternate block allocation at read operation If the ARRE flag in the MODE SELECT parameter permits the automatic alternate block allocation, the HDDs automatically execute the alternate block allocation and data duplication on the defective data block detected during the READ or READ EXTENDED command. This allocation method is the same as with the REASSIGN BLOCKS command (alternate sector treatment).
Data Format Type 2 (Reassignment of write fail sector) 1) Commands to be applied WRITE WRITE EXTENDED FORMAT UNIT WRITE at executing WRITE AND VERIFY 2) Application requirements / processing When WRITE/WRITE EXTENDED command detects any Servo error (e.g. Write offtrack error) and cannot be recovered within pre-determined retry number (specified in Mode Parameter). For the sectors around defective Servo, alternate blocks are allocated and the data of this WRITE commands are re-written.
CHAPTER 4 Installation Requirements 4.1 Mounting Requirements 4.2 Power Supply Requirements 4.3 Connection Requirements This chapter describes the environmental, mounting, power supply, and connection requirements. 4.1 Mounting Requirements 4.1.1 Dimensions Figures 4.1 show the dimensions of the HDDs and the location of the mounting screw holes.
Installation Requirements [Unit: mm] (*) is a dimention between the screw holes for the bottom mouting. Figure 4.

Inclination from a vertical or horizontal plane should not exceed 5°. (a) Horizontal –1 (b) Horizontal –2 (c) Vertical –1 (d) Vertical –2 (e) Upright mounting –1 (f) Upright mounting –2 Direction of gravity Figure 4.
Installation Requirements 4.1.3 Notes on mounting Damage Never remove any labels from the HDD or deface them in any way. (1) Mounting screw Use No.6-32UNC (2) Mounting frame structure Special attention must be given to mount the HDDs as follows. a) Use the frame with an embossed structure, or the like. Mount the HDDs with making a gap of 2.5 mm or more between the HDDs and the frame of the system. b) As shown in Figure 4.
4.1 Mounting Requirements (3) Limitation of side-mounting Mount the HDDs using the 4 screw holes at the both ends on the both sides as shown in Figure 4.4. Do not use the center hole by itself. In case of using the center hole, it must be used in combination with 2 holes on both ends. (Total 6 screws for 6 holes enclosed) Figure 4.4 (4) Limitation of side-mounting Limitation of bottom-mounting Use all 4 mounting holes on the bottom face.
Installation Requirements (5) Environmental temperature Temperature condition at installed in a cabinet is indicated with ambient temperature measured 30 mm from the HDD. At designing the system cabinet, consider following points. • Make a suitable air flow so that the DE surface temperature never exceed 60°C. • Cool the PCBA side especially with air circulation inside the cabinet. Confirm the cooling effect by measuring the surface temperature of specific ICs and the DE.
4.1 Mounting Requirements (6) External magnetic field The HDD should not be installed near the ferromagnetic body like a speaker to avoid the influence of the external magnetic field. (7) Leak magnetic flux The HDDs use a high performance magnet to achieve a high speed seek. Therefore, a leak magnetic flux at surface of the HDDs are large. Mount the HDDs so that the leak magnetic flux does not affect to near equipment.
Installation Requirements 4.2 Power Supply Requirements (1) Allowable input voltage and current The power supply input voltage measured at the power supply connector pin of the HDDs (receiving end) must satisfy the requirement given in Subsection 2.1.3. (For other requirements, see Items (4) and (5) below.) (2) Current waveform (reference) Figure 4.6 shows the spin-up current waveform of+5V DC and +12V DC.
4.2 Power Supply Requirements Figure 4.7 shows the Max Seek current waveform of+5V DC and +12V DC. Time (2 sec/div) Time (2 sec/div) Time (2 sec/div) Time (2 sec/div) Time (2 sec/div) Time (2 sec/div) Figure 4.7 (3) Current waveform (Max seek) Power on/off sequence The order of the power on/off sequence of +5V DC and +12V DC, supplied to the HDDs, does not matter.
Installation Requirements (5) Noise filter To eliminate AC line noise, a noise filter should be installed at the AC input terminal on the HDD power supply unit. The specification of this noise filter is as follows: • Attenuation: 40 dB or more at 10 MHz • Circuit construction: T-configuration as shown in Figure 4.8 is recommended. Figure 4.8 4.3 Connection Requirements 4.3.1 Connector location AC noise filter Figure 4.9 shows a location of the interface connector. Figure 4.

CHAPTER 5 Installation 5.1 Notes on Handling HDDs 5.2 Setting 5.3 Mounting HDDs 5.4 Checking Operation after Installation and Preparing the HDDs for Use 5.5 Dismounting HDDs This chapter describes the notes on handling HDDs, setting, mounting HDDs, confirming HDD operations after installation and preparation for use, and dismounting HDDs. 5.1 Notes on Handling HDDs The items listed in the specifications in Table 2.3 must be strictly observed.
Installation (2) Unpackaging a) Use a flat work area. Check that the "This Side Up" sign side is up. Handle the package on soft material such as a rubber mat, not on hard material such as a desk. b) Be careful not to give excess pressure to the internal unit when removing cushions. c) Be careful not to give excess pressure to the PCBA and interface connector when removing the HDD from the Fcell (Fig. 6.2). d) Do not remove any labels from the HDD. Never open the DE for any reason.
5.2 Setting 5.2 Setting 5.2.1 Port Address Every device that uses the SAS interface has a unique SAS address, and commands use an SAS address to identify each device for I/O operations. Every HDD is assigned a unique SAS address before shipment from the factory, so setting of an address is not required before the HDDs are used. 5.3 Mounting HDDs 5.3.
Installation 5.4 Checking Operation after Installation and Preparing the HDDs for Use 5.4.1 Checking initial operation The procedure for verifying operation after power-on is explained below. (1) Initial diagnosis at the time of power-on: a) When the HDDs are turned on, the LED blinks and the HDDs perform the initial self-diagnosis (controller hardware diagnosis).
5.4 Checking Operation after Installation and Preparing the HDDs for Use c) Issue the REQUEST SENSE command to collect sense data. When sense data has been collected successfully, perform an analysis to check for recoverable errors, and retry operations for recovery from any such errors. (5) Checking at abnormal end When sense data can be obtained, analyze the sense data and retry recovery for a recoverable error.
Installation (2) FORMAT UNIT command Initialize entire recording surface of the disk with the FORMAT UNIT command. The FORMAT UNIT command initializes entire surface of the disk using the P lists, verifies data blocks after initialization, and allocates an alternate block for a defect block detected with verification. With initialization, the pattern specified with the initialization data pattern field is written into all bytes of all logical data blocks.
5.4 Checking Operation after Installation and Preparing the HDDs for Use 5.4.3 Setting parameters The user can specify the optimal operation mode for the user system environments by setting the following parameters with the MODE SELECT or MODE SELECT EXTENDED command: • • • Error recovery parameter Caching parameter Control mode parameter With the MODE SELECT or MODE SELECT EXTENDED command, specify 1 for the "SP" bit on CDB to save the specified parameter value on the disk.
Installation (1) Error recovery parameters The following parameters are used to control operations such as HDD internal error recovery: a.
5.4 Checking Operation after Installation and Preparing the HDDs for Use (2) Caching parameters (page code = 8) The following parameters are used to optimize HDD Read-Ahead caching operations under the system environments. Refer to Chapter 3 "Data Buffer Management" of the SAS INTERFACE MANUAL for further details.
Installation (4) Port control parameters The following parameters are used to control the ready LED signal behavior. Parameter • READY LED MEANING 5.5 Default value 0 (LED is on when HDD is ready) Dismounting HDDs Since the method and procedure for dismounting the HDD, etc. depends on the locker structure of the system, etc., the work procedure must be determined in consideration of the requirements specific to the system. This section describes the general procedure and notes on dismounting the HDD.
CHAPTER 6 Diagnostics and Maintenance 6.1 Diagnostics 6.2 Maintenance 6.3 Operation Check 6.4 Troubleshooting 6.5 Packaging This chapter describes diagnostics and maintenance. 6.1 Diagnostics 6.1.1 Self-diagnostics The HDDs have the following self-diagnostic function. This function checks the basic operations of the HDDs. • • Initial self-diagnostics Online self-diagnostics (SEND DIAGNOSTIC command) Table 6.1 lists the contents of the tests performed with the self-diagnostics.
Diagnostics and Maintenance Brief test contents of self-diagnostics are as follows. a. Hardware function test This test checks the basic operation of the controller section, and contains following test. • • • RAM (microcode is stored) Peripheral circuits of microprocessor (MPU) Data buffer b. Seek test This test checks the positioning operation of the HDD using several seek modes (2 points seek, 1 position sequential seek, etc.).
6.1 Diagnostics (2) Online self-diagnostics (SEND DIAGNOSTIC command) The initiator can make the HDDs execute self-diagnostics by issuing the SEND DIAGNOSTIC command. The initiator 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 UnitOfl bit. When the UnitOfl bit on the CDB is set to 0, the HDDs execute the hardware function test only once.
Diagnostics and Maintenance b) When an error is detected in the hardware function test, the HDDs post the CHECK CONDITION status for all I/O operation request except the REQUEST SENSE command. The error status is not cleared even if the error information (sense data) is read. Only when the power is turned off or re-turned on, the status can be cleared. When this status is cleared, the HDDs execute the initial self-diagnostics again (see item (1)). Refer to Subsection 4.4.
6.2 Maintenance 6.2 Maintenance See Section 5.1 and 6.5 for notes on packaging and handling when returning the HDD. Data loss Save data stored on the HDD to other media before requesting repair. Fujitsu does not assume responsibility if data is corrupted during servicing or repair. 6.2.1 Precautions Take the following precautions to prevent injury during maintenance and troubleshooting: High temperature To prevent injury, never touch the HDD while it is hot.
Diagnostics and Maintenance 6.2.2 Maintenance requirements (1) Preventive maintenance Preventive maintenance is not required. (2) Service life See "(3) Service life," in Subsection 2.1.5. (3) Parts that can be replaced in the field The PCBA cannot be replaced in the field. The DE cannot be replaced in the field. (4) Service system and repairs Fujitsu has the service system and repair facility for the HDD. Contact Fujitsu representative to submit information for replacing or repairing the HDD.
6.2 Maintenance 6.2.3 Maintenance levels If an HDD is faulty, replace the whole HDD since repair requires special tools and environment. This section explains the two maintenance levels. (1) (2) 6.2.4 Field maintenance (HDD replacement) • This replacement is done at the user's site. • Replacement uses standard tools. • Replacement is usually done by the user, retail dealer, distributor, or OEM engineer. Factory maintenance (parts replacement) • This replacement can only be done by Fujitsu.
Diagnostics and Maintenance 6.2.5 Tests This HDD can be tested in the following ways: • • • Initial seek operation check (See Subsection 6.3.1) Operation test (See Subsection 6.3.2) Diagnostic test (See Subsection 6.3.3) Figure 6.1 shows the flow of these tests. Start Start self-test by turning the power on Test results OK? No Check host system (Table 6.
6.3 Operation Check 6.3 Operation Check 6.3.1 Initial seek operation check If an error is detected during initialization by the initial seek operation check routine at power-on, the spindle motor of the HDD stops, and then the HDD becomes unusable. For an explanation of the operation check before the initial seek, refer to the Section 5.4. 6.3.2 Operation test While the host computer is processing data, the HDDs monitor HDD operation including data processing, command processing, and seek operations.
Diagnostics and Maintenance 6.4 Troubleshooting 6.4.1 Outline of troubleshooting procedures This section explains the troubleshooting procedures for HDD errors. Depending on the maintenance level, analyze the error to detect a possibly faulty part (HDD, or HDD part). Full-scale troubleshooting is usually required if the error cause is not known. If the error cause is clear (e.g., abnormal noise in DE or burning of the PCBA), troubleshooting is straightforward. 6.4.
6.4 Troubleshooting Table 6.2 Item DC power level System-level field troubleshooting Recommended work Check that the DC voltage is within the specified range (±5%). For +5V DC, measure the voltage between pin P8 (+5V) of the interface connector and the nearest PCBA mounting screw (GND) from the interface connector, and confirm the value is from 4.75 to 5.25 VDC.
Diagnostics and Maintenance 6.4.3 Troubleshooting at the repair site For maintenance at this level, we recommend additional testing of the HDD and signal checking. The sense data posted from the HDDs help with troubleshooting. This sense data makes the error type clear (functional, mechanical, or electrical error). Chapter 7 error analysis by sense data, and gives supplementary information on finding the error cause (faulty part). Table 6.3 lists how to detect a faulty HDD subassembly.
6.5 Packaging 6.4.4 Troubleshooting with parts replacement in the factory This manual does not cover troubleshooting at the factory level. 6.4.5 Finding possibly faulty parts Finding possibly faulty parts in the field was explained in Subsection 6.4.2. This manual does not cover finding possibly faulty parts at the factory level. 6.5 Packaging When the HDD is returned to Fujitsu, the following methods are recommended. 6.5.1 Unitary packaging Figure 6.
Diagnostics and Maintenance (3) Put the above unitary packaging (packed in FCELL) into the conductivity bag by securing the cushion. (4) Put the drive with conductivity bag into the cardboard box. (5) Put the desiccant (10g) into the conductivity bag. (6) Seal the conductivity bag with the packaging tape, then close the cardboard box. 6.5.2 Multi-box packaging (upper) (lower) Figure 6.
6.5 Packaging (2) Put unitary packaging (FCELL) in the cushion (lower). • At this time, FCELL is put in the cushion (lower) so that the FCELL opening may become downward. The I/F connector may become upward. • For less than 20 HDDs, insert the HDDs starting from the slot with the smallest number in Figure 6.4. Then place the empty FCELL in the empty slot.

CHAPTER 7 Error Analysis 7.1 Sense Data Collection 7.2 Sense Data Analysis This chapter explains in detail how sense data collected from an HDD is used for troubleshooting. Sense data reflects an error in the HDD, and helps with troubleshooting. 7.1 Sense Data Collection 7.1.1 Sense data When HDDs post a CHECK CONDITION status, the current command or queued command is cleared. In such a case, the HDDs generate sense data about the command-issuing initiator.

7.2 Sense Data Analysis 7.2 Sense Data Analysis 7.2.1 Error information indicated with sense data Table 7.1 lists the definition of sense data. For details of the following sense data, refer to Chapter 6 "Sense Data Error Recovery Methods" of the SAS INTERFACE MANUAL. Subsection 7.2.2 onwards explain troubleshooting using sense data. Table 7.1 Definition of sense data Sense data Sense key Additional sense code Additional sense code qualifier 3 0C 03 A write to a disk terminated abnormally.
Error Analysis 7.2.2 Sense data (3-0C-03), (4-32-01), (4-40-xx), (4-C4-xx), and (4-44-xx) Sense data (3-0C-03), (4-32-01), (4-40-xx), (4-C4-xx), and (4-44-xx) indicate one of the following: • A target sector could not be detected using the sector counter. • A seek process overran the specified time. • A write to a disk terminated abnormally. • An error occurred in power-on self-diagnosis. • An HDD error occurred. The symptoms above are generally caused by an error in a PCBA or DE. 7.2.
Glossary Additional Sense Code This is a 1-byte code displayed in the sense data and is information which specifies the type of error that was detected. CDB Command Descriptor Block A series of data which describes commands related to input/output operations, sent from the initiator to the target. Command This is a command to a target to perform an input/output operation, and it is described as the CDB. Initiator This is an SAS device which initiates input and output operations on the SAS bus.
