Standard (non-error) test cases are expected to succeed and there should be no ERROR statements in the logs. SCSI Inquiry and Mode Sense commands will fail if the drive is not connected to a SCSI adapter.

Error test cases will have many ERROR statements but should have no failure statements. Failure statements indicate that an expected error code was not received.

Test case logs need to be examined to verify that data is returned as expected. Not all returned data is automatically checked. Script comments will note what data is expected.
