If Error Type #1 reappears and becomes a chronic problem, the fault may
be with the tape drive unit, and it could be intermittent in nature. In this
case, replace the tape drive unit with a new tape drive unit and repeat
"Error 1 - Repair Procedure." Refer to Step 5 of the ‘‘
Tape Maintenance
and Repair Procedures’’ section for directions on how to replace the tape
drive unit.
c. Error Type #257 indicates that the tape cartridge is write-protected. To
disable the tape write-protect feature, move the sliding write-protect
switch (which is labeled RECORD) on the tape cartridge away from the
RECORD position. The RECORD position is indicated by an arrow pointing
to the left. Error Type #257 can then be cleared by issuing the test tape
[a/b] repeat 2 command for the tape drive unit that has the error.
d. Error Type #1793 is reported whenever the system software detects an
uncorrectable tape block error during a read or write operation on the
tape.
An uncorrectable tape error is one in which a block error persists during
a read or write operation to the tape. Errors of this type were unable to be
corrected by several attempts at rereading or rewriting the block on the
tape. This type of error is most likely the result of one or more hard errors
on the tape (for example, a scratch or a hole in the tape that spans
multiple sectors).
The auxiliary data field indicates the file on the tape in which the error was
detected. Refer to Table C for a list of possible auxiliary data field values
and the corresponding tape file.
Since this error may be the result of a problem with either the tape or the
tape drive unit, the tape cartridge should be changed first. If the problem
persists, the tape unit should be changed. When this error is first
detected, follow "Error Type #1793 - Repair Procedure."
Error Type #1793 - Repair Procedure:
1.Replace the tape cartridge in the tape unit on which the error occurred
with a new tape cartridge.
2.[G1.2, G3iV1.1-286] Issue the test tape [a/b] long clear command for
the associated tape drive unit.
[G1.1] Issue the test tape [a/b] long repeat 3 command for the
associated tape drive unit. If the system release is earlier than
G1.1, refer to Note (o) also.
3.If all tests pass, assume that the problem has been resolved.
If some tests fail, resolve those errors and repeat Step #2.
4.If translations have not already been saved onto the new tape, issue the
save translations command.
5.If the system contains recorded announcements, issue the save
announcements command.
