Tape drive hardware problem. The drive determined that a tape
path or read/write error occurred. To prevent damage to the drive
or tape, you cannot insert a cartridge if the current cartridge was
successfully ejected. The error code might clear when you cycle power
to the tape drive or place it in maintenance mode. If the problem
persists, replace the drive.
|
|
Tape drive or media error. The tape
drive determined that an error occurred, but it cannot isolate the
error to faulty hardware or to the tape cartridge. Ensure that the
tape cartridge is the correct media type:
- Ultrium 1, 2, 3, 4, 5, 6,
7, and M8 cartridges are not supported in the Ultrium 9 tape drive.
- Drive does not accept an expired Cleaning Cartridge.
- Drive does not accept a WORM cartridge when diagnostic tests are
run in Maintenance mode.
- Drive does not write over existing data sets on a WORM cartridge.
Ensure that you are appending data sets on WORM media rather than
attempting to write over existing data sets.
If the tape cartridge is the correct media type, complete
this action: |

Problems with Writing Data
If
the problem occurred while the tape drive was writing data to the
tape, retry the operation with a different cartridge:
- If the operation succeeds, the original cartridge was defective.
Copy data from the defective cartridge and discard it.
- If the operation fails and another tape drive is available, insert
the cartridge into the other unit and retry the operation.
- If the operation fails, discard the defective cartridge.
- If the operation succeeds, insert a scratch data cartridge into
the first unit and run Function code 1: Run drive diagnostics.
- If the diagnostic tests fail, replace the tape drive.
- If the diagnostic tests succeed, the error was temporary.
- If the operation fails and another tape drive is not available,
insert a scratch data cartridge into the unit and run Function code 1: Run drive diagnostics.
- If the diagnostic tests fail, replace the tape drive.
- If the diagnostic tests succeed, discard the cartridge.
If the problem occurs with multiple tape cartridges, run Function code 1: Run drive diagnostics:
- If the diagnostic tests fail, replace the tape drive.
- If the diagnostic tests succeed, run Function code H: Test head .
- If the diagnostic test fails, replace the tape drive.
- If the diagnostic test succeeds, replace the cartridges that caused the problem.
The error code clears when you remove the tape cartridge or place the tape drive in Maintenance
mode.

Tape drive or media error. The tape drive determined an error occurred because of a faulty
tape cartridge or an invalid tape cartridge. Ensure that the tape cartridge is the correct media
type:
- Ultrium 1, 2, 3, 4, 5, 6,
7, and M8 cartridges are not supported in the Ultrium 9 tape drive.
- Drive does not accept an expired Cleaning Cartridge.
- Drive does not accept a WORM cartridge when diagnostic tests are run in Maintenance mode.
- Drive does not accept an FMR tape unless the drive is completing Function code 8: Unmake FMR tape.
- Drive does not write over existing data sets on a WORM cartridge. Ensure that you are appending
data sets on WORM media rather than attempting to write over existing data sets.
- Drive does not Create FMR tape (Maintenance code 3) with a
cartridge that is already an FMR tape. Use another cartridge or run Maintenance mode Function code 8: Unmake FMR tape.
- Drive does not Unmake FMR tape (Maintenance code 8) with a
cartridge that is not an FMR tape.
If the tape cartridge is the correct media type, try another tape cartridge. If the problem
occurs with multiple tape cartridges, use this procedure:
- If possible, run the tape cartridge in a different tape drive. Replace the media if the
operation in the other unit fails, and
or displays. If the operation succeeds, run Function code E: Test cartridge & media.Attention: When you run the
Test Cartridge & Media diagnostic test, data on the suspect tape is
overwritten. Use only a scratch data cartridge to run the test.
- If the diagnostic test fails, replace the media.
- If the diagnostic test succeeds, clean the drive head (see Cleaning the drive head) and run Function code 1: Run drive diagnostics.
- If the drive diagnostic test fails, replace the drive.
- If the drive diagnostic test succeeds, complete the operation that produced the initial media
error.
The error code clears when you remove the tape cartridge or place the tape drive in
Maintenance mode.

Interface problem. The tape drive determined that a failure occurred in the tape drive 's
hardware or in the host bus. See Troubleshooting Guide. If displays while "Function Code 6: Host Interface Test" was running:
- Verify that the correct interface wrap tool was attached in the correct interface
port during the test. The test fails if the correct interface wrap tool is not attached.
Note: The interface wrap test is not supported on the USB port and displays an invalid error
if run.
- If the correct interface wrap tool was attached during the test, replace the drive. The error
code clears when you place the tape drive in Maintenance mode.
|
|
Tape drive or RS-422 error. The tape drive determined that
a failure occurred in the tape drive 's hardware or in the RS-422
connection. See Function code 7: Run RS-422 wrap test or
refer to the library procedures to isolate the problem to the drive.
The error code clears when you place the tape drive in Maintenance
mode. |
|
Degraded operation. The tape drive determined that a problem occurred which degraded the
operation of the tape drive, but it did not restrict continued use. If the problem persists,
determine whether the problem is with the drive or the media.
Note: The drive is usable, though the Single-character Display continues to indicate an error and
the Fault light flashes. The error code might clear when you cycle power to
the tape drive or place it in Maintenance mode.
To determine whether the problem is with
the drive hardware, or the tape media, complete these procedures:
- If possible, run the tape cartridge in a different drive. Replace the media if the operation in
the other drive fails, and
or displays. If the operation succeeds, run the Test Cartridge &
Media diagnostic test (see Function code E: Test cartridge & media).
- If the Test Cartridge & Media diagnostic test fails, replace the
media. If it runs successfully, clean the failing drive and run the drive diagnostic tests (see
Cleaning the drive head and Function code 1: Run drive diagnostics).
When you begin this test, the diagnostic
test begins the loop sequence. Time the first loop by pressing Unload once
to stop the diagnostic test after the completion of the first loop,
then record the time that it takes for the test to complete. Compare
the recorded time with the "Approximate Run Time". If the test runs
successfully but the execution time is longer than the "Approximate
Run Time", run Function code F: Write performance test.
If the Write Performance Test fails, replace the media and exit Maintenance
mode.
If the drive diagnostic tests run successfully, complete the operation that produced the initial
drive error.
- If the problem persists, replace the drive.
If it is not possible to run the tape cartridge in a different drive, complete these
procedures:
- Clean the failing drive and run the drive diagnostic tests (see Cleaning the drive head and Function code 1: Run drive diagnostics).
When you begin this test, the diagnostic
test begins the loop sequence. Time the first loop by pressing Unload once
to stop the diagnostic test after the completion of the first loop,
then record the time that it takes for the test to complete. Compare
the recorded time with the "Approximate Run Time". If the test runs
successfully but the execution time is longer than the "Approximate
Run Time", run Function code F: Write performance test.
If the Write Performance Test fails, replace the media and exit Maintenance
mode.
If the drive
diagnostic tests run successfully, run the Test Cartridge & Media
diagnostic test (see Function code E: Test cartridge & media).
- If the Test Cartridge & Media diagnostic test fails, replace the
media. If it runs successfully, complete the operation that produced the initial drive error.
- If the problem persists, replace the drive.

Fiber AL_PA conflict. Two drives on fiber
loop have the same AL_PA. Modify the tape drive AL_PA to eliminate
the conflict. NOT SUPPORTED ON THIS DRIVE. |
|
Encryption Error. Displayed when the drive
detects an error that is associated with an encryption operation.
If the problem occurred while the tape drive was writing data to,
or reading data from, tape:
- Check the host application to ensure that the host application
is providing the correct encryption key.
- Refer to the IBM LTO Ultrium Tape Drive SCSI Reference for the sense
data that is returned for an encryption operation.
- Retry the encryption operation after the host application problems
are resolved.
- Check the operation of the tape drive by resetting the drive and
running POST. See Table 1.
- Refer to the error code displayed on the SCD if the drive reset
and POST fails.
- Retry the encryption operation if the drive reset and POST complete
without errors.
- Check the media.
- Ensure that the correct media is used. Data encryption is supported by LTO Ultrium 4 and later Data Cartridges only.
- Retry the encryption operation with the tape cartridge in another
encryption enabled drive. Replace the media if the problem repeats
with the same tape cartridge in multiple drives.
If the problem occurred while the tape drive was running
POST or diagnostic tests, replace the drive.
The error code
clears with the first attempted write/read after the encryption key
is changed, or when the drive is placed in Maintenance mode.

|
Fiber Port offline. Displayed when the drive fiber port received a port
bypass command from another port on the Fibre Channel network. |
|
Fibre Channel error. No light is displayed if the drive fiber port does not
detect light. |
|
Incompatible media. The tape
drive detected that an unsupported cartridge was loaded or the cartridge
that is loaded has an incompatible format. |
|
Write operation to a write protected cartridge
was attempted (includes any attempt to overwrite a WORM protected
tape). Ensure that the tape cartridge is the correct media type. If the tape cartridge
is the correct media type, check the write-protect switch on the cartridge.
The drive does not write to a write-protected cartridge. The error
code clears when you remove the tape cartridge or place the tape drive
in Maintenance mode. |
