6.1.4Response to diagnostic command

When the master device receives an EXECUTE DEVICE DIAGNOSTIC command and the slave device is present, the master device checks the PDIAG- signal for up to 6 seconds to see if the slave device has completed the self-diagnosis successfully.

The master device does not check the DASP- signal.

After the slave device receives the EXECUTE DEVICE DIAGNOSTIC command, it shall report the result of the self-diagnostics to the master device as described below:

PDIAG- signal: negated within 1 ms and asserted within 5 seconds then negated within 6 seconds.

When the IDD is set to a slave device, the IDD asserts the DASP- signal when negating the PDIAG- signal, and negates the DASP- signal when asserting the PDIAG- signal.

When the unrecoverable error occurs during the write operation, the command execution is stopped. Then, when the drive receives the next command, it generates an interrupt of abnormal end. However an interrupt of abnormal end is not generated when a write automatic assignment succeeds. However, since the host may issue several write commands before the drive generates an interrupt of abnormal end, the host cannot recognize that the occurred error is for which command generally. Therefore, it is very hard to retry the unrecoverable write error for the host in the write cache operation generally. So, take care to use the write cache function I, Place des Etas-Unis, SILIC 310, 94588 Rungis Cedex, FRANCE FUJITSU LIMITED Reader Comment Form
