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.
PERIPHERAL DEVICE WRITE FAULT-Drive electronics did not report successful
completion to a Write operation.
MICROCODE HAS BEEN CHANGED–Illegal firmware code is reprogrammed.
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.
MIC READ ERROR
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.
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.
INVALID COMMAND OPERATION CODE-Invalid or Unsupported command.
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.
LOGICAL UNIT NOT SUPPORTED-The SDX-550V 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.
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.
PARAMETER NOT SUPPORTED-Unsupported page requested. Refer to the Field
Pointer (Bytes 15-17) to identify the illegal bit or field.
PARAMETER VALUE INVALID
COMMAND SEQUENCE ERROR-Write Buffer command when tape is inserted and
not at BOT.
SAVING PARAMETERS NOT SUPPORTED
INVALID BITS IN IDENTIFY MESSAGE-Identify message was not 80h or C0h.
