SCSI error : <<host> <channel> id...

SCSI error : <host channel id lun> return code = result

host

SCSI Host No.

channel

SCSI Channel No.

id

SCSI ID

lun

SCSI LUN

result

code representing the error

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

In most cases, one or more additional error messages regarding the SCSI device will be displayed with more concreate information after this message. The recommended action would depend on such the possilbe succeding messages.
