- 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.
- vs
- Vendor Specific.
