Sense Key
This field provides the top level reason for the error or exception condition.
SENSE KEY
DESCRIPTION
0h
NO SENSE. Indicates no specific sense key information is available.
1h
RECOVERED ERROR. Indicates that the last command completed successfully with
some recovery action performed by the target. This code is not used for the Library.
2h
NOT READY. Indicates that the logical unit addressed cannot be accessed. Operator
intervention may be required to correct this condition.
3h
MEDIUM ERROR. Indicates that the command terminated with a non-recovered error
condition that was probably caused by a flaw in the medium or an error in the recorded
data. This sense key may also be returned if the target is unable to distinguish
between a flaw in the medium and a specific hardware failure (sense key 4h).
4h
HARDWARE ERROR. Indicates that the target detected a non-recoverable hardware
failure (for example, controller failure, device failure, parity error, etc.) while performing
the command or during a self-test.
5h
ILLEGAL REQUEST. Indicates that there was an illegal parameter in the command
descriptor block or in the additional parameters supplied as data for some commands.
If the target detects an invalid parameter in the command descriptor block, then it shall
terminate the command without altering the medium. If the target detects an invalid
parameter in the additional parameters supplied as data, then the target may have
already altered the medium. This sense key may also indicate that an invalid
IDENTIFY message was received.
6h
UNIT ATTENTION. Indicates that the removable medium may have been changed or
the target has been reset.
7h
DATA PROTECT. Indicates that a command that writes the medium was attempted on
a tape block that is protected from this operation. This code is not used for the Library.
8h
BLANK CHECK. Indicates that the device encountered blank medium or format-
defined end-of-data indication while reading. This code is not used for the Library.
Bh
ABORTED COMMAND. Indicates that the target aborted the command. The initiator
may be able to recover by trying the command again.
Dh
VOLUME OVERFLOW. Indicates that a buffered peripheral device has reached the
end-of-partition and data may remain in the buffer that has not been written to the
medium. This code is not used for the Library.
Information Bytes
This field is always set to zero.
Additional Sense Length
This specifies the number of additional sense bytes to follow. If the
allocation length of the command descriptor block is too small to transfer all
of the additional sense bytes, the additional sense length is not adjusted to
reflect the truncation.
Command Specific Information Bytes
Command Specific Bytes are handled as device specific and can be logged by
the operating system on error conditions. This field is not used for any
implemented commands.
