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.

a)When an error is detected in the seek or write/read test, the subsequent command can be accepted correctly. When the command other than the REQUEST SENSE and NO OPERATION is issued from the same initiator, the error information (sense data) is cleared.

b)When an error is detected in the hardware function test, the HDD posts the CHECK CONDITION status for all I/O operation request except the REQUEST SENSE command. The error status is not cleared even if the error information (sense data) is read. Only when the power is turned off or re-turned on, the status can be cleared. When this status is cleared, the HDD executes the initial self-diagnostics again (see item (1)).

Refer to Subsection 4.4.1 “SEND DIAGNOSTIC (1D)” of the Fibre Channel Interface Specifications for further details of the command specifications.

Data loss

When the SEND DIAGNOSTIC command terminates with the CHECK CONDITION status, the initiator must collect the error information using the REQUEST SENSE command. The RECEIVE DIAGNOSTIC RESULTS command cannot read out the error information detected in the self-diagnostics.

6.1.2Test programs

The basic operations of the HDD itself can be checked with the self-diagnostic function. However, to check general operations such as the host system and interface operations in a status similar to the normal operation status, a test program that runs on the host system must be used.

The structure and functions of the test program depend on the user system requirements. Generally, it is recommended to provide a general input/output test program that includes devices connected to the loop and input/output devices on other I/O ports.

Including the following test items in the test program is recommended to test the HDD functions generally.
