18 July 2001 T10/1236-D Revision 20Table 138 defines the content of the SELF-TEST RESULTS field.Table 138 — Self-test results valuesValue0h1h2h3h4h5h6h7h8h-EhFhDescriptionThe self-test completed without error.The background self-test was aborted by the application client using a SEND DIAGNOSTICS command(see 7.23) with the SELF-TEST CODE field set to 100b (Abort background self-test).The self-test routine was aborted by an application client using a method other than a SEND DIAG-NOSTICS command with the SELF-TEST CODE field set to 100b (e.g., by a task management function,by a reset, or by issuing an exception command as defined in 5.4.3).An unknown error occurred while the device server was executing the self-test and the device serverwas unable to complete the self-test.The self-test completed with a failure in a test segment, and the test segment that failed is not known.The first segment of the self-test failed.The second segment of the self-test failed.Another segment of the self-test failed (see the SELF-TEST SEGMENT NUMBER field).ReservedThe self-test is in progress.The SELF-TEST NUMBER field identifies the self-test that failed and consists of either:a) the number of the segment that failed during the self-test; orb) the number of the test that failed and the number of the segment in which the test was run, using a vendorspecific method for placing the two values in the one field.When the segment in which the failure occurred cannot or need not be identified, the SELF-TEST NUMBER field shallcontain 00h.The TIMESTAMP field contains the total accumulated power-on hours for the device server at the time the self-testwas completed. If the test is still in progress, the content of the TIMESTAMP field shall be zero. If the power-on hoursfor the device server at the time the self-test was completed is greater than FFFFh then the content of theTIMESTAMP field shall be FFFFh.The ADDRESS OF FIRST FAILURE field contains information that locates the failure on the media. If the logical unitimplements logical blocks, the content of the ADDRESS OF FIRST FAILURE field is the first logical block address wherea self-test error occurred. This implies nothing about the quality of any other logical block on the logical unit, sincethe testing during which the error occurred may not have been performed in a sequential manner. This value shallnot change (e.g., as the result of block reassignment). The content of the ADDRESS OF FIRST FAILURE field shall beFFFFFFFFFFFFFFFFh if no errors occurred during the self-test or if the error that occurred is not related to anidentifiable media address.The SENSE KEY, ADDITIONAL SENSE CODE, and ADDITIONAL SENSE CODE QUALIFIER fields may contain a hierarchy ofadditional information relating to error or exception conditions that occurred during the self-test represented in thesame format used by the sense data (see 7.20).dpANS SCSI Primary Commands - 2 (SPC-2) 183
