[b] The values of the LOG PARAMETER control bits [2] through [8] for self-test results log parameters is
specified in Table 126.
Table 126: Parameter control bits for self-test results log parameters
Bit Value
DU 0
DS 0
TSD 0
ETC 0
TMC xxx
LBIN 1
LP 1
[c] The PARAMETER LENGTH field shall contain 10h.
[d] The SELF-TEST CODE field contains the value in the Self-test Code field of the SEND DIAGNOS-
TICs command that initiated this self-test (see SEND DIAGNOSTICs command).
[e] SELF-TEST RESULTS field values is shown in Table 127.
Table 127: Self-test results values
Value Description
0h Self-test completed without error
1h The background self-test was aborted by the application client using a SEND DIAGNOSTICs com-
mand with the Self-test Code field set to 100b (Abort background self-test).
2h 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 Section 9.2).
3h An unknown error occurred while the device server was executing the self-test and the device server
was unable to complete the self-test.
4h The self-test completed with a failure in a test segment, and the test segment that failed is not
known.
5h The first segment of the self-test failed.
6h The second segment of the self-test failed.
7h Another segment of the self-test failed (see note [12] The Self-test Segment Number field).
8h - Eh Reserved.
Fh The self-test is in progress.
[f] The SELF-TEST SEGMENT NUMBER field identifies the number of the segment that failed during
the self-test. When the segment that failed cannot or need not be identified, this field shall contain
00h.
[g] The TIMESTAMP field contains the total accumulated power-on hours for the device server at the time
the self-test was completed. If the test is still in progress, the content of the Timestamp field shall be
zero. If the power-on hours for the device server at the time the self-test was completed is greater than
FFFFh then the content of the Timestamp field shall be FFFFh.
[h] The ADDRESS OF FIRST FAILURE field contains information that locates the failure on the media. If
the logical unit implements logical blocks, the content of the ADDRESS OF FIRST FAILURE field is
the first LOGICAL BLOCK ADDRESS where a self-test error occurred. This implies nothing about the
quality of any other logical block on the logical unit, since the testing during which the error occurred
may not have been performed in a sequential manner. This value shall not change (e.g., as the result
of block reassignment). The content of the ADDRESS OF FIRST FAILURE field shall be
FFFFFFFFFFFFFFFFh if no errors occurred during the self-test or if the error that occurred is not
related to an identifiable media address.
