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 hard disk drives (HDDs). The drives are high performance large capacity 3.5" type hard disk drives with an embedded Fibre-Channel controller.
General Description 1.1 Standard Features (1) Compactness In a compact enclosure having the 3.5-inch HDD form factor, the HDD contains an FC-AL controller, which supports the Arbitrated Loop technology (FC-AL), a Fibre Channel technology defined by the related ANSI standard.
1.1 Standard Features The continuous processing up to [64K-1] blocks in a command can be achieved, and HDD can perform continuous read/write operation when processing data blocks on several tracks or cylinder. (7) Multi-segment data buffer The data buffer is 8M bytes. Data is transferred between Fibre Channel Loop and disk media through this data buffer. This feature provides the suitable usage environment for users.
General Description (12) Error recovery The HDD can try to recover from errors in Fibre Channel Loop 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 recover processing by these error recovery functions of the HDD.
1.2 Hardware Structure (19) Diagnosis The HDD has a diagnostic capability which checks internal controller functions and drive operations to facilitate testing and repair. (20) Low power consumption By using highly integrated LSI components, the power consumption of the HDD is very low, and this enables the unit to be used in wide range of environmental conditions. (21) Low noise and low vibration The noise level is low; approx. 3.4 Bels at Ready for the drive. This makes it ideal for office use.
General Description (2) Heads The MR (Magnet - Resistive) of the CSS (contact start/stop) type heads are in contact with the disks when the disks are not rotating, and automatically float when the rotation is started. (3) Spindle motor The disks are rotated by a direct-drive hall-less DC spindle motor. The motor speed is controlled by a feedback circuit using the counter electromotive current to precisely maintain the specified speed.
1.3 System Configuration 1.3 System Configuration For the Fibre Channel, the ANSI standard defines Arbitrated Loop, Fabric, and Point-to-Point technologies. The drives support the Arbitrated Loop technology. Figure 1.2 gives an example of the FC-AL system configuration.

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 HDD. 3.1 Data Space The HDD manages the entire data storage area divided into the following three data spaces.
Data Format Cylinder –154 to ~ Cylinder –147 Internal test cylinder ~ Cell 0 1 0 Cylinder 0 1 • 28 29 30 • 57 Internal test space ~ SA139 Cylinder –143 to ~ Cylinder –4 Zone ~ • SA0 ~ ~ System space ~ User Space for Cell 0-0 Spare Sectors per Cell 0-0 User Space for Cell 1-0 Spare Sectors per Cell 1-0 • User Space (Primary Cylinder 0 - (n-1)) m-28 User Space for Cell P1-0 P1 • m Spare Sectors per Cell P1-0 (1) Alternate Cylinder User Space for Cell xx-1 1 : 17 Note: n User Space fo
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 cylinder of each zone. 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 HDD 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 HDD (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 HDD treats 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 HDD manages. • P list (Primary defect list): This list consists of defect location information available at the disk drive 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 specified lists (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 subsequent sectors in the cylinder by means of alternate sector treatment. Figure 3.
Data Format If above errors are detected during FORMAT UNIT command, the HDD allocates the alternate block(s) to the defective data blocks. Reassign procedure itself is the same as one in REASSIGN BLOCKS command. *1 (2) Certification is permitted when DCRT flag is cleared (DCRT flag=0) in FORMAT UNIT command. The HDD checks all initialized logical data blocks by reading them out after the above alternate block allocation is made to initialize (format) the disk.
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 HDD automatically executes 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.

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 PCA and interface connector when removing the drive from the Fcell. d) Never remove any labels from the drive. Never open the disk enclosure for any reason.
5.2 Setting 5.2 Setting 5.2.1 Loop ID setting When setting the fibre channel loop ID, use SEL0 to SEL6 of interface connector CN1. IN bit weighting, SEL6 corresponds to the MSB, SEL0 to the LSB, and 126 types of X'00' to X'7D' can be specified as loop IDs. 5.2.2 Mode settings (1) Motor start mode The method for start control of the HDD spindle motor can be set in accordance with Table 5.1. Table 5.
Installation 5.3 Mounting Drives 5.3.1 Mounting procedures Since mounting the drive depends on the system cabinet structure, determine the work procedures considering the requirements specific to each system. The general mounting method and items to be checked are shown below. See Subsection 4.1 for the details of requirements for installing the HDD.
5.4 Checking Operation after Installation and Preparing the HDD for Use 5.4 Checking Operation after Installation and Preparing the HDD for Use 5.4.1 Checking initial operation This section explains how to check operation after power is turned on. Since the initial operation of an HDD differs depending on the settings of the motor start mode, check the following initial operations according to the motor start mode set during installation.
Installation The Active LED goes off while the HDD command is being executed. For some commands, however, since the Active LED goes off for only a fraction of a second, the Active LED looks like it flashes or remains lit. 5.4.2 Checking connection When the initial operation is checked normally after power is turned on, check that the HDD is connected to the loop from the host system.
5.4 Checking Operation after Installation and Preparing the HDD for Use Motor starts when power is turned on d) (60 Figure 5.

Installation 5.5 Dismounting Drives Since the method and procedure for dismounting the disk drive for replacement of the drive, 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 drive. Damage 1. When dismounting the drive which is mounted on the system while power is supplied to it.
CHAPTER 6 Diagnostics and Maintenance 6.1 Diagnostics 6.2 Maintenance Information 6.3 Operation Check 6.4 Troubleshooting Procedures This chapter describes diagnostics and maintenance information. 6.1 Diagnostics 6.1.1 Self-diagnostics The HDD has the following self-diagnostic function. This function checks the basic operations of the HDD. • • Initial self-diagnostics Online self-diagnostics (SEND DIAGNOSTIC command) Table 6.
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) 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.).
6.1 Diagnostics The HDD does not reply to the loop for up to 2 seconds after the initial self-diagnostics is started.
Diagnostics and Maintenance When an error is detected in the self-diagnostics, the HDD terminates the SEND DIAGNOSTIC command with the CHECK CONDITION status. The initiator should issue the REQUEST SENSE command when the CHECK CONDITION status is posted. The sense data collected by the REQUEST SENSE command indicates the detail information of the error detected in the self-diagnostics. The HDD status after the CHECK CONDITION status is posted differs according to the type of the detected error.
6.2 Maintenance Information (1) Interface (loop) test The operations of the loop and data buffer on the HDD are checked with the WRITE BUFFER and READ BUFFER commands. (2) Basic operation test The basic operations of the HDD are checked by executing self-diagnosis with the SEND DIAGNOSTIC command (see Subsection 6.1.1).
Diagnostics and Maintenance 6.2.2 Maintenance requirements (1) Preventive maintenance Preventive maintenance is not required. (2) Service life See "(3) Service life," in Section 2.1.5. (3) Parts that can be replaced in the field The PCA 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 disk drive.
6.2 Maintenance Information Data loss Save data stored on the disk drive to other media before requesting repair. Fujitsu does not assume responsibility if data is destroyed during servicing or repair. See Section 5.1 for notes on packing and handling when returning the disk drive. 6.2.3 Maintenance levels If a disk drive is faulty, replace the whole disk drive since repair requires special tools and environment. This section explains the two maintenance levels.
Diagnostics and Maintenance 6.2.4 Revision numbers The revision number of the disk drive is represented with a letter and a number indicated on the label attached on the HDD. Figure 6.1 shows an example of the label. Figure 6.1 (1) Revision label (example) Indicating revision number at factory shipment When the disk drive is shipped from the factory, the revision number is indicated by deleting numbers in the corresponding letter line up to the corresponding number with = (see Figure 6.2).
6.2 Maintenance Information When the revision number is changed after the drive is shipped from the factory, Fujitsu issues "Engineering Change Request/Notice" in which the new revision number is indicated. When the user changes the revision number, the user should update the revision label as described in item (2) after applying the modification. At shipment Rev. A2 Revising at field Rev. A3 Figure 6.2 6.2.
Diagnostics and Maintenance 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 disk drive stops, and then the disk drive becomes unusable. For an explanation of the operation check before the initial seek, refer to the Section 5.4. 6.3.
Diagnostics and Maintenance 6.4 Troubleshooting Procedures 6.4.1 Outline of troubleshooting procedures This section explains the troubleshooting procedures for disk drive errors. Depending on the maintenance level, analyze the error to detect a possibly faulty part (disk drive, or disk drive 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 disk enclosure or burning of the PCA), troubleshooting is straightforward.
6.4 Troubleshooting Procedures 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 +5 VDC, measure the voltage between pin 20 (+5V) of the interface connector and the nearest PCA 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 disk drive and signal checking. The sense data posted from the HDD helps 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 disk drive subassembly.
6.4 Troubleshooting Procedures 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.
