An error occurred on a SCSI（Small Computer System Interface）device shown in the message with the corresponding SCSI number. A code refered by result consists of five pieces of the detailed error information. It's represented by 8 digit hexadecimal number in the format: 0x VW XX YY ZZ. The meaning of the each part is as follows:
V： error code to show actions after the error
0＝normal
1＝retry
others＝idle
Ｗ： error on the driver layer
0＝normal
4＝common error
6＝timeout
8＝sense error
others＝idle
XX： error on host
00＝normal
01＝timeout（fail to connect）
02＝timeout（fail to access because of the bus being busy）
03＝other timeout
04＝a designated error of a target device
05＝commands to be terminated abnormality
06＝parity error
07＝internal error
08＝commands to reset
09＝unexpected interrupt
0a＝taking back an error to upper layer
0b＝requesting a retry by lower layer
0c＝a command not to reduce a retry count
others＝idle
YY： message code
01＝expanded message code
02＝an HBA port stores the current data pointer
03＝an HBA port restore the data pointer stored
04＝the target closing the connection
05＝an error on HBA port
06＝the target terminates abnormally the current command
07＝never processing the last message
08＝idle status
09＝parity error
0a＝completion of command group
0b＝completion of command group
0c＝LU reset
20＝treating the command as HEAD OF QUEUE
21＝treating the command as ORDERED
22＝treating the command as SIMPLE ※ http://www.t10.org/ftp/t10/drafts/spi2/spi2r20a.pdf
ZZ： error on the device.The ZZ&0xfe value is equal to the error code
00＝normal
02＝Completion of preparing SENSE data
04＝It expresses completion of a specific command
08＝LU busy
10＝normal
14＝It expresses completion of a specific command
18＝interfering in the RESERVE state
22＝LU busy
28＝resource deficit of the HBA port side
30＝detecting an ACA (Auto Contingent Allegiance) state
40＝The command being canceled by other HBA ports ※ http://www.t10.org/ftp/t10/drafts/sam3/sam3r14.pdf
