When Post Error Reporting is disabled, deferred-check conditions are not reported to the host and temporary errors are not
reported in the sense data. This is the normal (default) setting for the drive. When the drive has Post Error Reporting disabled,
Function Code U will be displayed in Maintenance Mode. The drive will default to Post Error Reporting disabled after a reboot or
power off/on cycle.
1. Place the drive in Maintenance Mode. For instructions, see Entering Maintenance Mode.
2. Press the Unload Button once per second until P or U appears in the SCD. Function Code P or U will appear in the SCD to
indicate the current setting for Post Error Reporting. If you cycle past the code that you want, press the Unload Button
once per second until the code reappears.
3. Exit Maintenance Mode if you do not want to change the current setting for Post Error Reporting. For instructions, see
Exiting Maintenance Mode.
4. To disable Post Error Reporting, Press and hold the Unload Button for three seconds while P appears in the SCD. The
SCD changes to U after you release the Unload Button.
5. Press the Unload Button once per second to select another Maintenance Mode Function. To exit Maintenance Mode,
refer to Exiting Maintenance Mode.
Error Codes and Messages
If the drive detects a permanent error, it displays the error code on the SCD and flash the Amber Fault LED. (Green Ready LED
is Off.)
Make note of the SCD error code before removing a cartridge or clearing the SCD error code.
If an error occurred with a cartridge in the drive, push the Unload Button to eject the cartridge.
To clear the SCD error code and power cycle the drive, press the Unload Button for ten seconds. A drive dump is
created.
Attention: If the drive detects a permanent error and displays an error code other than 0, it automatically performs a drive
dump. If you force a drive dump, the existing dump is 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 1. LTO-7 Tape Drive Error Codes
Error Code Cause and Action
0
No error occurred and no action is required. This code displays when diagnostics have finished running and
no error occurred.
Note: The Single-character Display is blank during normal operation of the tape drive.
1
Temperature problem. The tape drive detected that the recommended operating temperature was
exceeded. Perform one or more of the following actions:
Ensure that the cooling fan is rotating and is quiet. If not, refer to your enclosure documentation.
Remove any blockage that prevents air from flowing freely through the tape drive.
Ensure that the operating temperature and airflow is within the specified range.
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.
2
Power problem. The tape drive detected that the externally supplied power is outside the specified voltage
limits (the tape drive is not operating). Perform the following actions:
Ensure that the power connector is properly seated.
Ensure that the proper dc voltages are being applied within the tolerances allowed.
If the proper voltages are not being applied, service the power supply.
If the proper voltages are being applied, power off/on the tape drive to see whether the problem
repeats.
Replace the tape drive if the problem persists.
The error code clears when you place the tape drive in maintenance mode.
