    1.1 Standard Features (1) 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. (2) SCSI/CCS standard The IDD provides not only SCSI basic

    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
  • Fujitsu MAH3091MC | Manual/User Guide - Page 23
    (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

    (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 The noise level is low; approx. 4.0 bels for MAH and MAJ series. This

    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 IDD has the following self-diagnostic function. This
  • Fujitsu MAH3091MC | Manual/User Guide - 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
  • Fujitsu MAH3091MC | Manual/User Guide - 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
  • Fujitsu MAH3091MC | Manual/User Guide - Page 107
    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. The INIT should issue the REQUEST SENSE
