• Test span
Selective self-test log provides for the definition of up to five test spans. If the
starting and ending LBA values for a test span are both zero, a test span is not
defined and not tested.
• Current LBA under test
As the self-test progress, the device shall modify this value to contain the LBA
currently being tested.
• Current span under test
As the self-test progress, the device shall modify this value to contain the test span
number currently being tested.
