    CHAPTER 1 GENERAL DESCRIPTION Standard Features Hardware Structure System Configuration This chapter describes the feature and configuration of the intelligent disk drives (IDD). IDDs are high performance large capacity 3.5 type fixed disk drives with an embedded SCSI controller. The MAT series disk drives support the Small Computer System Interface (SCSI) as described in the ANSI SCSI SPI-4 [T10/1365D Rev.10] to the extent described in this manual.
  • Page 18: Standard Features

    Standard Features Compactness Since the SCSI controller circuit is embedded in the standard 3.5 type 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 standard The IDD provides not only SCSI basic functions but also the following features: Arbitration Disconnection/Reconnection...
  • Page 19 Note: The maximum data transfer rate in asynchronous mode may be limited by the response time of initiator and the length of SCSI bus length. The maximum data transfer rate in synchronous mode may be limited by the cable length, transmission characteristics of the SCSI bus and the connected SCSI device number.
  • Page 20 Command queuing feature The IDD can queue maximum 128 commands, and optimizes the issuing order of queued commands by the reordering function. This feature realizes the high speed processing. 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.
  • Page 21 (15) Large capacity A large capacity can be obtained from 3.5 type disk drives 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. (16) Start/Stop of spindle motor Using the SCSI command, the host system can start and stop the spindle motor.
  • Page 22: Hardware Structure

    Hardware Structure An outer view of the IDD is given in Figures 1.1 and 1.2. The IDD is composed of the disk, head, spindle motor, mounted disk enclosure (DE) with actuator and air circulation filter, as well as read/write pre-amp with the printed circuit assembly (PCA) of the controller. Figure 1.1 NC model drives outer view Figure 1.2...
  • Page 23 Disks The disks have an outer diameter of 84 mm (3.3 inch) and an inner diameter of 25 mm (0.98 inch). The disks are good for at least 50,000 contact starts and stops. 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.
  • Page 24: System Configuration

    System Configuration Figure 1.4 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 operation as specified by SCSI devices which operate as initiator. SCSI bus (#14) (#15) Figure 1.3...
  • Page 25 SCSI bus configuration Up to eight SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 8-bit SCSI and up to 16 SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 16-bit SCSI in any combination.

  • Page 37: Alternate Spare Area

    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.
  • Page 38: Figure 3.2 Spare Area In Cell

    The number of spare sectors per cell can be specified from 0 to 240. The default for the spare sectors number is 240. Cell Note: This drive manages alternate spare areas for each cell, which is a set of cylinders. One cell consists of 29 cylinders.
  • Page 39: Track Format

    3.1.3 Track format 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.

Sync Mark (SM1, SM2) In this field, special pattern in the specified length in bytes is written. This special pattern indicates the beginning of the data field.
  • Page 42: Format Capacity

    3.1.5 Format capacity The size of the usable area for storing user data on the IDD (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.
  • Page 43 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 IDD 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.
  • Page 44: Defect Management

    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 IDD 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.
  • Page 45 The alternate block allocation is executed by the FORMAT UNIT command, the REASSIGN BLOCKS command, or the automatic alternate block allocation. Refer to OEM Manual–SCSI Logical Specifications–for details of specifications on these commands. The logical data block is allocated to the next physically continued sectors after the above sector slip treatment is made. On the other hand, the logical data block is allocated to spare sectors which are not physically consecutive to the adjacent logical data blocks.
  • Page 46: Figure 3.7 Alternate Block Allocation By Format Unit Command

    : n represents a logical data block number : Defective sector : Unused spare sector Figure 3.7 Alternate block allocation by FORMAT UNIT command During FORMAT UNIT command, alternate block allocation is conducted in following cases: 1) Unrecovered write offtrack condition during a media write 2) Uncorrectable Data Error during a media read (certification) *1 If above errors are detected during FORMAT UNIT command, the IDD allocates the alternate block(s) to the defective data blocks.
  • Page 47: Figure 3.8 Alternate Block Allocation By Reassign Blocks Command

    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. The alternate block is allocated to unused spare sectors in the alternate cylinder. Figure 3.8 is examples of the alternate block allocation by the REASSIGN BLOCKS command.

    CHAPTER 6 DIAGNOSTICS AND MAINTENANCE Diagnostics Maintenance Information Operation Check Troubleshooting Procedures This chapter describes diagnostics and maintenance information. Diagnostics 6.1.1 Self-diagnostics The IDD has the following self-diagnostic function. This function checks the basic operations of the IDD. Initial self-diagnostics Online self-diagnostics (SEND DIAGNOSTIC command) Table 6.1 lists the contents of the tests performed with the self-diagnostics.
  • Page 98 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.).
  • Page 99 The IDD does not reply to the SCSI bus for up to 2 seconds after the initial self-diagnostics is started. After that, the IDD can accept the I/O operation request correctly, but the received command, except the executable commands under the not ready state (such as INQUIRY, START/STOP UNIT), is terminated with the CHECK CONDITION status (NOT READY [=2]/logical unit is in process of becoming ready [=04-01] or logical unit not ready, initializing command required [=04-02]) during the interval from the spindle motor becomes stable to the IDD...
  • Page 100: Test Programs

    When an error is detected in the self-diagnostics, the IDD terminates the SEND DIAGNOSTIC command with the CHECK CONDITION status. The INIT 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.

    Interface (SCSI bus) test The operations of the SCSI bus and data buffer on the IDD are checked with the WRITE BUFFER and READ BUFFER commands. Basic operation test The basic operations of the IDD are checked by executing self-diagnosis with the SEND DIAGNOSTIC command (see Subsection 6.1.1).

    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. Replacement includes maintenance training and OEM engineer support. OEM engineers usually support retail dealers and distributors.
  • Page 105: Revision Numbers

    6.2.4 Revision numbers The revision number of the disk drive is represented with a letter and a number indicated on the revision label attached to the DE. Figure 6.1 shows the revision label format. Figure 6.1 Revision label 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).
  • Page 106: Tools And Test Equipment

    IMPORTANT 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.

    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 a PCA), troubleshooting is straightforward.
