Error Log; Self-Test - Hitachi HDS725050KLA360 Specifications

Logging of reported errors is supported. The device provides information on the last five errors that the device
reported as described in the SMART error log sector. The device may also provide additional vendor specific
information on these reported errors. The error log is not disabled when SMART is disabled. Disabling SMART
disables the delivering of error log information via the SMART READ LOG SECTOR command.
If a device receives a firmware modification, all error log data is discarded and the device error count for the life of
the device is reset to zero.

attributes are updated accordingly during the execution of self-test.
If it is interrupted by the host during the self-tests, the device services the host command.
