Description
Valid
When set to 1, this field indicates that the information bytes contain
valid information as defined in the ANSI SCSI-2 specification.
Error Code
A value of 70h indicates a current error – the report is associated with
the most recently received command.
A value of 71h indicates a deferred error – the report is associated
with a previous command and not as a result of the current
command.
No other values are returned in this field.
Segment Number
This value of this byte is always 0.
Filemark
This bit indicates that the current command has read a Filemark.
EOM
End of Medium. This bit indicates that an End of Medium condition
(End of Partition or Beginning of Partition) exists. The warning is also
given by setting the Sense Key to NO SENSE and the Additional Sense
Qualifier to End of Partition or Beginning of Partition.
ILI
Incorrect Length Indicator. This bit indicates that the requested
logical block length did not match the logical block length of the
data on the tape medium. Only READ or VERIFY may cause this bit to
be set.
Sense Key
In most cases, Additional Sense Code and/or Qualifier information is
available. The codes and qualifiers are covered in detail in Table 5-89.
Information Bytes
These bytes contain the differences (residue) of the requested length
minus the actual length in bytes, blocks, or Filemarks, as determined
by the command. Negative values are indicated by two’s
complement notation. The bytes are valid for all READ, WRITE, SPACE,
and VERIFY tape commands for which a CHECK CONDITION status
has been generated. The information bytes are 0 for MODE SELECT /
SENSE, INQUIRY, READ BLOCK LIMITS, and TEST UNIT READY.
