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.). The positioning operation is checked with confirming the physical address information by reading the ID field from the data block on track 0 after completion of the seek operation to the target cylinder.

c.Write/read test

This test check the write/read function by using the Internal test space of the disk drive.

(1)Initial self-diagnostics

When power is turned on, the IDD starts initial self-diagnostics. The initial self-diagnostics checks the basic operations of the hardware functions.

If an error is detected in initial self-diagnosis, the Fault LED lights up. In this status, the IDD reports the CHECK CONDITION status to all input/output operation requests other than the REQUEST SENSE command. When the CHECK CONDITION status is posted, the INIT should issue the REQUEST SENSE command. The sense data obtained with the REQUEST SENSE command details the error information detected with the initial self-diagnostics.

Even if CHECK CONDITION status and sense data are posted, the LED continues blinking. Only when the SCSI bus is reset, the BUS DEVICE RESET message is issued, or the power is turned off or re-turned on, this status can be cleared. When this status is cleared, the IDD executes the initial self-diagnosis again.
