Members
error_count Error Count: a 64-bit incrementing error count, indicating a unique identifier
for this error. The error count starts at 1h, is incremented for each unique
error log entry, and is retained across power off conditions. A value of 0h
indicates an invalid entry; this value is used when there are lost entries or
when there are fewer errors than the maximum number of entries the controller
supports. If the value of this field is FFFFFFFFh, then the field shall be set
to 1h when incremented (i.e., rolls over to 1h). Prior to NVMe 1.4, processing
of incrementing beyond FFFFFFFFh is unspecified.
sqid Submission Queue ID: indicates the Submission Queue Identifier of the command
that the error information is associated with. If the error is not specific to
a particular command, then this field shall be set to FFFFh.
cmdid Command ID: indicates the Command Identifier of the command that the error is
associated with. If the error is not specific to a particular command, then
this field shall be set to FFFFh.
status_field
Bits 15-1: Status Field: indicates the Status Field for the command that
completed. If the error is not specific to a particular command, then this
field reports the most applicable status value. Bit 0: Phase Tag: may
indicate the Phase Tag posted for the command.
parm_error_location
Parameter Error Location: indicates the byte and bit of the command parameter
that the error is associated with, if applicable. If the parameter spans
multiple bytes or bits, then the location indicates the first byte and bit of
the parameter. Bits 10-8: Bit in command that contained the error. Valid
values are 0 to 7. Bits 7-0: Byte in command that contained the error. Valid
values are 0 to 63.
lba LBA: This field indicates the first LBA that experienced the error condition,
if applicable.
nsid Namespace: This field indicates the NSID of the namespace that the error is
associated with, if applicable.
vs Vendor Specific Information Available: If there is additional vendor specific
error information available, this field provides the log page identifier
associated with that page. A value of 0h indicates that no additional
information is available. Valid values are in the range of 80h to FFh.
trtype Transport Type (TRTYPE): indicates the Transport Type of the transport
associated with the error. The values in this field are the same as the TRTYPE
values in the Discovery Log Page Entry. If the error is not transport related,
this field shall be cleared to 0h. If the error is transport related, this
field shall be set to the type of the transport - see enum nvme_trtype.
csi Command Set Indicator: This field contains command set indicator for the
command that the error is associated with.
opcode Opcode: This field contains opcode for the command that the error is
associated with.
cs Command Specific Information: This field contains command specific
information. If used, the command definition specifies the information
returned.
trtype_spec_info
Transport Type Specific Information
rsvd Reserved: [62:42]
log_page_version
This field shall be set to 1h. If set, csi and opcode will have valid values.
