Error Codes and Messages

Table 15 gives descriptions of the errors and messages that pertain to the drive,
and tells what to do when you receive them.
Attention: If the drive detects a permanent error and displays an error code other
than
existing dump will be overwritten and data will be lost. After you force a drive
dump, do not turn off the power to the drive or you may lose the dump data.
Table 15. Error codes on the Single-character Display. To clear error and cycle power, press the Unload Button for
ten seconds. A drive dump will be created.
Error Code
No error occurred and no action is required. This code displays:
0
v When power is cycled (turned off, then on) to the tape drive.
v When diagnostics have finished running and no error occurred.
Note: The Single-character Display is blank during normal operation of the tape drive.
Cooling problem. The tape drive detected that the recommended operating temperature was
1
exceeded. Perform one or more of the following actions:
v Ensure that the cooling fan is rotating and is quiet. If not, refer to your enclosure
documentation.
v Remove any blockage that prevents air from flowing freely through the tape drive.
v Ensure that the operating temperature and airflow is within the specified range (see "Physical
Specifications" on page 10).
v If the operating temperature is within the specified range and the problem persists, replace the
drive.
The error code clears when you power-off the tape drive or place it in maintenance mode.
Power problem. The tape drive detected that the externally supplied power is approaching the
8
specified voltage limits (the tape drive is still operating) or is outside the specified voltage limits
(the tape drive is not operating). Perform the following action:
1. Ensure that the power connector is properly seated.
2. Ensure that the proper dc voltages are being applied within the tolerances allowed (see
"Physical Specifications" on page 10).
3. If the proper voltages are being applied but the problem persists, replace the unit.
The error code clears when you power-off the tape drive or place it in maintenance mode.
Firmware problem. The tape drive determined that a firmware error occurred. Perform the
3
following action:
1. Collect a drive dump from one of the following:
Note: Do not force a new dump; the tape drive has already created one.
v Server's SCSI interface by using a device driver utility or system tool (for instructions about
reading a drive dump from tape, visit the Web at http://www.ibm.com/storage/lto)
v Ultrium Tape Drive (to copy and read a drive dump, use "Function Code 5: Copy Drive
Dump" on page 36)
2. Power the tape drive off and on, then retry the operation that produced the error.
3. If the problem persists, download new firmware and retry the operation.
4. If the problem persists, send the drive dump that you collected in step 1 to your IBM Support
Center.
The error code clears when you power-off the tape drive or place it in maintenance mode.
