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 might lose the dump data.
Table 10. Error codes on the single-character display
Error Code
No error occurred and no action is required. This code displays when diagnostics have finished
0
running and no error occurred.
Note: The single-character display is blank during normal operation of the tape drive.
Temperature 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
Appendix C, "Specifications," on page 65).
Clear the error code by power cycling the tape drive or placing the drive in Maintenance Mode. If
the operating temperature and airflow are within the specified range and the problem persists,
replace the drive.
Power problem. The tape drive detected that the externally supplied power is outside the
8
specified voltage limits (the tape drive is not operating). Perform the following actions:
1. Ensure that the power connector is properly seated.
2. Ensure that the proper dc voltages are being applied within the tolerances allowed (see
Appendix C, "Specifications," on page 65).
3. If the proper voltages are not being applied, service the power supply.
4. If the proper voltages are being applied, power off/on the tape drive to see if the problem
repeats.
5. Replace the tape drive if the problem persists.
The error code clears when you place the tape drive in Maintenance Mode.
Firmware problem. The tape drive determined that a firmware error occurred. Perform the
3
following actions:
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 host interface by using a device driver utility or system tool
v Ultrium Tape Drive (to copy and read a drive dump, use "Function Code 5: Copy drive
dump" on page 24)
2. Power the tape drive off and on, then retry the operation that produced the error.
3. If the problem persists, download new firmware by completing the following steps.
Note: Changes are made periodically to the IBM website. The actual procedure might vary
slightly from what is described in this document.
a. Go to http://www.ibm.com/systems/support/.
b. Under Product support, click Hardware upgrades.
c. Under Popular links, click Tape files to display the matrix of downloadable files for tape
drives.
d. Download the appropriate files and retry the operation.
4. If the problem persists, send the drive dump that you collected in step 1 to your IBM support
representative.
The error code clears when you place the tape drive in Maintenance Mode.
