• 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.
