  • Page 16: Chapter 1 General Description

    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-inch fixed disk drives with an embedded SCSI controller. The interface between the IDD and host system is based on SCSI (Small Computer System Interface) standard [ANSI X3.131 - 1986: Small Computer System Interface (SCSI), ANSI X3.131-1994: Small Computer System Interface - 2 (SCSI-2)].

  • Page 17: Standard Features

    Standard Features Compactness Since the SCSI controller circuit is embedded in the standard 3.5-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...
  • Page 18 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 on the single-ended SCSI bus may be limited by the cable length, transmission characteristics of the SCSI bus and the connected SCSI device number.
  • Page 19 (10) Error recovery The IDD can try to recover from errors in 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 recover processing by these error recovery functions of the IDD.

  • Page 20: Hardware Structure

    (18) Low power consumption By using highly integrated LSI components, the power consumption of the IDD is very low, and this enables the unit to be used in wide range of environmental conditions. (19) Low noise and low vibration Approx. 4.2 bels for the IDD. This makes it ideal for office use. The IDD has rubber vibration isolators, which minimize the transfer of vibration.

    MAA3182:10 MAB3091, MAC3091:5 MAB3045, MAC3045:3 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 Actuator The actuator, which uses a rotary voice coil motor (VCM), consumes little power and generates little heat. The head assembly at the end of the actuator arm is controlled and positioned via feedback of servo information in the data. The actuator positions heads on the CCS zone over the disk and is locked by the mechanical lock when the power is off or the spindle motor is stopped.

  • Page 25: System Configuration

    System Configuration Figure 1.8 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. Figure 1.8 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...
  • Page 26 Addressing of peripheral device Each SCSI device on the bus has its own unique address (SCSI ID:#n in Figure 1.6). For input/output operation, a peripheral device attached to the SCSI bus that operates as target is addressed in unit called as logical unit. A unique address (LUN: logical unit number) is assigned for each logical unit.

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 default number of cylinders in the user space is 9,041 for MAA31xxxx, 8,491 for MAB30xxxx and 8,691 for MAC30xxxx.

  • Page 40: Alternate Spare Area

    3.1.2 Alternate spare area The alternate spare area is provided in the last track of each primary cylinder in the user space, and in the last track of the cylinder and the alternate cylinder. The spare area in each cylinder 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.

  • Page 41: 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.

  • Page 42: Track Skew/Cylinder Skew

    Track skew and cylinder skew To avoid waiting for one turn involved in head and cylinder switching, the first logical data block in each track is shifted by the number of sectors (track skew and cylinder skew) corresponding to the switching time. Figure 3.5 shows how the data block is allocated in each track.

  • Page 43: Sector Format

    3.1.4 Sector format Each sector on the track consists of an ID field, a data field, and a gap field which separates them. Figure 3.6 gives sector format examples. Each sector on the track consists of the following fields: Gaps (G1) The gap length at the time of formatting (initializing) is listed in Figure 3.6.

Single burst errors with lengths of up to 16 bits for each logical block can be detected. 24-byte data error detection/correction code for the data field. It is possible to on-the-fly correct the single burst errors with lengths of up to 89 bits.

  • Page 45: 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 3.4 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.

  • Page 46: Logical Data Block Addressing

    Logical Data Block Addressing Independently of the physical structure of the disk drive, the IDD adopts the logical data block addressing as a data access method on the disk medium. The IDD relates a logical data block address to each physical sector at formatting. Data on the disk medium is accessed in logical data block units.

  • Page 47: 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 48 Alternate sector treatment: The logical data block corresponding to defective sectors is allocated to unused spare sectors in the same cylinder or unused spare sectors in the alternate cylinder. The alternate block allocation is executed by the FORMAT UNIT command, the REASSIGN BLOCKS command, or the automatic alternate block allocation.

  • Page 49: 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 If the data block verifying operation (certification) is not permitted (DCRT flag = 0) in the FORMAT UNIT command, the IDD checks all initialized logical data blocks by reading them out after the above alternate block allocation is made to initialize (format) the disk.

  • Page 50: 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. If there are unused spare sectors in the same cylinder as the specified defective logical data block, the alternate block is allocated to these unused spare sectors.
  • Page 51 Automatic alternate block allocation If the ARRE flag in the MODE SELECT parameter permits the automatic alternate block allocation, the IDD automatically executes the alternate block allocation and data duplication on the defective data block detected during the READ EXTENDED command. allocation method is the same as with the REASSIGN BLOCKS command (alternate sector treatment).

    Use mounting screws whose lengths inside the drive mounting frame are 4 mm or less when the screws are tightened (see Figure 4.6). When mounting the drive, be careful not to damage parts on the PCAs. 3) Check that the DE (signal ground) does not touch the system cabinet chassis (frame ground).

  • Page 92: Confirming Operations After Installation And Preparation For Use

    Be careful of the insertion directions of the SCSI connectors. With the system in which terminating resistor power is supplied via the SCSI cable, if the power is turned on, the overcurrent protection fuse of the terminating resistor power supplier may be blown or the cable may be burnt if overcurrent protection is not provided.

    5.6.2 Checking SCSI connection When the initial operation is checked normally after power is turned on, check that the IDD is connected to the SCSI bus from the host system. Although checking the connection depends on the structure of the host system, this section describes the general procedures. Checking procedure Issuing the commands and determining the end status depends on the start mode of the spindle motor and UNIT ATTENTION report mode (specified with setting terminal).

    CHAPTER 6 DIAGNOSTICS AND MAINTENANCE Diagnostics Maintenance Information 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 105 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 106 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 not ready [=04-00]) during the interval from the spindle motor becomes stable to the IDD becomes ready.

  • Page 107: Test Programs

    When an error is detected in 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.
