+================================================================+A definition of the status byte codes is given below.
GOOD. This status indicates that the target has successfully completed the
command.CHECK CONDITION. This status indicates that a contingent allegiance condition
has occurred.CONDITION MET. This status or INTERMEDIATE-CONDITION MET is returned whenever
the requested operation is satisfied (see the SEARCH DATA and PRE-FETCH
commands).BUSY. This status indicates that the target is busy. This status shall be
returned whenever a target is unable to accept a command from an otherwise
acceptable initiator (i.e., no reservation conflicts). The recommended
initiator recovery action is to issue the command again at a later time.INTERMEDIATE. This status or INTERMEDIATE-CONDITION MET shall be returned for
every successfully completed command in a series of linked commands (except
the last command), unless the command is terminated with CHECK CONDITION,
RESERVATION CONFLICT, or COMMAND TERMINATED status. If INTERMEDIATE or
INTERMEDIATE-CONDITION MET status is not returned, the series of linked
commands is terminated and the I/O process is ended.INTERMEDIATE-CONDITION MET. This status is the combination of the CONDITION
MET and INTERMEDIATE statuses.RESERVATION CONFLICT. This status shall be returned whenever an initiator
attempts to access a logical unit or an extent within a logical unit that is
reserved with a conflicting reservation type for another SCSI device (see the
RESERVE and RESERVE UNIT commands). The recommended initiator recovery action
is to issue the command again at a later time.COMMAND TERMINATED. This status shall be returned whenever the target
terminates the current I/O process after receiving a TERMINATE I/O PROCESS
message. This status also indicates that a contingent allegiance
condition has occurred.QUEUE FULL. This status shall be implemented if tagged queuing is
implemented. This status is returned when a SIMPLE QUEUE TAG, ORDERED QUEUE
TAG, or HEAD OF QUEUE TAG message is received and the command queue is full.
The I/O process is not placed in the command queue.

Sense Key (0h-7h) Descriptions
+========-====================================================================+
| Sense | Description |
| Key | |
|--------+--------------------------------------------------------------------|
| 0h | NO SENSE. Indicates that there is no specific sense key |
| | information to be reported for the designated logical unit. This |
| | would be the case for a successful command or a command that |
| | received CHECK CONDITION or COMMAND TERMINATED status because one |
| | of the filemark, EOM, or ILI bits is set to one. |
|--------+--------------------------------------------------------------------|
| 1h | RECOVERED ERROR. Indicates that the last command completed |
| | successfully with some recovery action performed by the target. |
| | Details may be determinable by examining the additional sense |
| | bytes and the information field. When multiple recovered errors |
| | occur during one command, the choice of which error to report |
| | (first, last, most severe, etc.) is device specific. |
|--------+--------------------------------------------------------------------|
| 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 (FORMAT UNIT, SEARCH DATA, |
| | etc.). 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. |
| | information about the unit attention condition. |
|--------+--------------------------------------------------------------------|
| 7h | DATA PROTECT. Indicates that a command that reads or writes the |
| | medium was attempted on a block that is protected from this |
| | operation. The read or write operation is not performed. |
+=============================================================================+Sense Key (8h-Fh) Descriptions+========-====================================================================+
| Sense | Description |
| Key | |
|--------+--------------------------------------------------------------------|
| 8h | BLANK CHECK. Indicates that a write-once device or a sequential- |
| | access device encountered blank medium or format-defined end-of- |
| | data indication while reading or a write-once device encountered a|
| | non-blank medium while writing. |
|--------+--------------------------------------------------------------------|
| 9h | Vendor Specific. This sense key is available for reporting vendor|
| | specific conditions. |
|--------+--------------------------------------------------------------------|
| Ah | COPY ABORTED. Indicates a COPY, COMPARE, or COPY AND VERIFY |
| | command was aborted due to an error condition on the source |
| | device, the destination device, or both. |
|--------+--------------------------------------------------------------------|
| Bh | ABORTED COMMAND. Indicates that the target aborted the command. |
| | The initiator may be able to recover by trying the command again. |
|--------+--------------------------------------------------------------------|
| Ch | EQUAL. Indicates a SEARCH DATA command has satisfied an equal |
| | comparison. |
|--------+--------------------------------------------------------------------|
| 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. A RECOVER BUFFERED DATA |
| | command(s) may be issued to read the unwritten data from the |
| | buffer. |
|--------+--------------------------------------------------------------------|
| Eh | MISCOMPARE. Indicates that the source data did not match the data|
| | read from the medium. |
|--------+--------------------------------------------------------------------|
| Fh | RESERVED. |
