Error Code

Cause and Action

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:

1. 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.

2. 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:

1. 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

2. 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.

3. If the problem persists, replace the drive.

If it is not possible to run the tape cartridge in a different drive, complete these procedures:

1. Clean the failing drive and run the drive diagnostic tests (see

Cleaning the drive head

and

Function code 1: Run drive diagnostics

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

2. If the Test Cartridge & Media diagnostic test fails, replace the media. If it runs successfully, complete the operation that produced the

initial drive error.

3. If the problem persists, replace the drive.

The tape drive must be cleaned. Clean the tape drive. See

Cleaning the drive head

The error code clears when you clean the tape drive or place it in Maintenance mode.
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:

1. 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.

2. 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.

3. 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.
The drive is performing media optimization.
