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-900V 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.
