Data List Length field and shall assume a length of zero.
[4] If packetized failure data is provided, the Packetized Failures Valid (RSPVALID) bit shall be set to one and
the Packetized Failures List Length field shall specify the number of bytes in the Packetized Failures field.
The Packetized Failures List Length field shall contain a length of 4. Other lengths are reserved for future
standardization. If no packetized failure data is provided, the packetized failures valid bit shall be set to
zero. The initiator shall ignore the Packetized Failures List Length field and shall assume a length of zero.
The Packetized Failures field (see Table
55) contains information describing the packetized failures
detected during the execution of a task. The Packetized Failures field shall contain valid information if the
target detects any of the conditions described by the packetized failure code (see Table
56).
[5] The Status field contains the status of a task that completes. See Section 7.3, Table 64, for a list of status
codes.
[6] The iuCRC field shall use the algorithm defined in Subsection 11.3, ANSI SCSI Parallel Interface (SPI-5),
T10/1525D.
The Packetized Failures field (see Table 55) contains information describing the packetized failures detected
during the execution of a task. The Packetized Failures field shall contain valid information if the target detects
any of the conditions described by the packetized failure code (see Table
56).
Table 55: Packetized Failures field
[1] The Packetized Failures Code is defined in Table 56.

The Sense Data field contains the information specified by the SCSI Primary Commands-4 (SPC-4), T10/1731-
D, for presentation by the REQUEST SENSE command (see Seagate SCSI Command Reference Manual,
Part number 100293068). The proper sense data shall be presented when a SCSI status byte of Check Condi
-
tion is presented as specified by the SCSI Primary Commands-4 (SPC-4), T10/1731-D and this manual.
