6.Command Specification

REQUEST SENSE

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. Host should 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. Host should 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.

 

 

 

 

83

06

MIC READ ERROR

 

 

 

05h

 

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.

 

 

 

 

 

1A

00

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

 

 

 

the Command Descriptor Block. 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.

2400 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.

2500 LOGICAL UNIT NOT SUPPORTED - The SDX-800V has an embedded SCSI controller with only one Logical Unit (LUN). The error indicates that the LUNTRN field in the Identify message was not ZERO.

2600 INVALID FIELD IN PARAMETER LIST - Test Number,

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

Diagnostic test is not Host assessable.

2601 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.
