REQUEST SENSE

6.Command Specification

04h

 

 

HARDWARE ERROR. Indicates that the drive detected a non-recoverable hardware

 

 

 

failure not related to the tape (for example, controller failure, device failure, parity

 

 

 

error, etc).While performing the command or during a self-test. If a previously

 

 

 

acknowledged write-type operation was the cause, the valid bit is set. The error code

 

 

 

in sense byte 16 will indicate the specific problem. Refer to the error code table in the

 

 

 

diagnostics clause for more information.

 

 

 

 

 

03

00

PERIPHERAL DEVICE WRITE FAULT - Drive electronics did not report successful

 

 

 

completion to a Write operation.

 

 

 

 

 

3F

01

MICROCODE HAS BEEN CHANGED – Illegal firmware code is reprogrammed.

 

 

 

 

 

44

00

INTERNAL TARGET FAILURE - Any unexpected internal error

 

 

 

Conditions Indicating a Non-recoverable hardware failure. Refer to the field

 

 

 

replaceable unit code field (sense byte 14) to determine which part of the drive is

 

 

 

failing. Initiator will issue SEND DIAGNOSTICS with the self-test bit set to thoroughly

 

 

 

test the drive. This sense information could also be returned after a send diagnostics

 

 

 

command ends with a CHECK CONDITION status. initiator will issue RECEIVE

 

 

 

DIAGNOSTICS RESULTS for more details. Possible causes: buffer

 

 

 

overrun/under-run, format violation, mechanical status time-out, internal data parity

 

 

 

error, byte count mismatch, incorrect micro processor operation, unexpected SCSI

 

 

 

protocol chip interrupt.

06

MIC Read Error

 

 

 

 

05h

 

 

ILLEGAL REQUEST. Indicates that there was an illegal parameter in the CDB or in

 

 

 

the additional parameters supplied as data for some commands. If the target detects

 

 

 

an invalid parameter in the CDB, then it will 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.

 

 

 

 

 

1A

00

PARAMETER LIST LENGTH ERROR - Indicates that the Parameter Length error in

 

 

 

the CDB. Either the value does not fall on a Header, Page or Block descriptor

 

 

 

boundary or the Parameter List Length is unexpectedly large.

 

 

 

 

 

20

00

INVALID COMMAND OPERATION CODE - Invalid or Unsupported command.

 

 

 

 

 

24

00

INVALID FIELD IN CDB – Bits are set in one or more fields are not supported or are

 

 

 

Reserved. Refer to the Field Pointer (Bytes 15-17) to identify the illegal bit or field.

 

 

 

 

 

26

00

INVALID FIELD IN PARAMETER LIST - Test Number,

 

 

 

Configuration Number Header, or Field in the Parameter List was invalid or selected

 

 

 

Diagnostic test is not initiator assessable.

 

 

 

 

 

26

01

PARAMETER NOT SUPPORTED - Unsupported page requested. Refer to the Field

 

 

 

Pointer (Bytes 15-17) to identify the illegal bit or field.

 

 

 

 

 

26

02

PARAMETER VALUE INVALID

 

 

 

 

 

2C

00

COMMAND SEQUENCE ERROR - Write Buffer command when tape is inserted and

 

 

 

not at BOT.

 

 

 

 

 

39

00

SAVING PARAMETERS NOT SUPPORTED

 

 

 

 

 

3D

00

INVALID BITS IN IDENTIFY MESSAGE - Identify message was not 80h or C0h.
