Members

dsts Device Self-test Status: Indicates the device self-test code and the status of the operation
(see enum nvme_status_result and enum nvme_st_code).

seg Segment Number: Iindicates the segment number where the first self-test failure occurred. If
Device Self-test Status (dsts) is not set to #NVME_ST_RESULT_KNOWN_SEG_FAIL, then this field
should be ignored.

vdi Valid Diagnostic Information: Indicates the diagnostic failure information that is reported.
See enum nvme_st_valid_diag_info.

rsvd Reserved

poh Power On Hours (POH): Indicates the number of power-on hours at the time the device self-test
operation was completed or aborted. This does not include time that the controller was
powered and in a low power state condition.

nsid Namespace Identifier (NSID): Indicates the namespace that the Failing LBA occurred on. Valid
only when the NSID Valid bit (#NVME_ST_VALID_DIAG_INFO_NSID) is set in the Valid Diagnostic
Information (vdi) field.

flba Failing LBA: indicates the LBA of the logical block that caused the test to fail. If the
device encountered more than one failed logical block during the test, then this field only
indicates one of those failed logical blocks. Valid only when the NSID Valid bit
(#NVME_ST_VALID_DIAG_INFO_FLBA) is set in the Valid Diagnostic Information (vdi) field.

sct Status Code Type: This field may contain additional information related to errors or
conditions. Bits 2:0 may contain additional information relating to errors or conditions that
occurred during the device self-test operation represented in the same format used in the
Status Code Type field of the completion queue entry (refer to enum nvme_status_field).
Valid only when the NSID Valid bit (#NVME_ST_VALID_DIAG_INFO_SCT) is set in the Valid
Diagnostic Information (vdi) field.

sc Status Code: This field may contain additional information relating to errors or conditions
that occurred during the device self-test operation represented in the same format used in
the Status Code field of the completion queue entry. Valid only when the SCT Valid bit
(#NVME_ST_VALID_DIAG_INFO_SC) is set in the Valid Diagnostic Information (vdi) field.
