b. Error 1 indicates that the tape unit does not recognize that a cartridge is
inserted into the tape drive. If, in fact, there is no cartridge in the drive, the
problem can be corrected by simply inserting a cartridge. Follow the
directions given in "Error Type #1 - Repair Procedure."
If there is a tape cartridge inserted into the tape drive, the problem is that
certain tape or tape drive failures may cause the tape drive to erroneously
report "missing tape" errors (tape Error Type #1 OR Aux Data value 9024).
Since this error may be the result of a problem with either the tape or the
tape drive unit, the tape cartridge should be replaced first. If the problem
persists, the tape unit should be replaced. When this error is first
detected, follow "Error Type #1 - Repair Procedure."
Error Type #1 - Repair Procedure:
1. Replace the tape cartridge (if one exists) in the tape unit associated
with this error with a new tape cartridge.
2. Issue the test tape [a/b] repeat 2 command for the tape drive unit
that has the error.
3. If all the tests pass, assume that the problem has been resolved.
If some of the tests fail, resolve the corresponding 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.
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).
