Troubleshooting Suggestions

2If the Hardware or Firmware Error or Manual Intervention LED is flashing after the tape drive is rebooted, the tape may be stuck. Contact Customer Support.

In the unlikely event the LTO-3 Tape Drive stops communicating with the host computer, use the following procedure to reset the drive and eject a cartridge (if necessary).

Caution: When you perform an emergency cartridge eject, any data currently in the drive or host's buffers will not be written to the tape and the tape record may not be correctly terminated with an End-of-Data mark. If the End-of-Data mark is not written to the tape, you will not be able to append any data to that tape unless you overwrite the existing data on the tape.

To perform an emergency reset, hold down the load/unload button between 5 to 15 seconds, and then release it.

If there is no tape in the drive, the drive firmware reboots the drive and begins the power-on self-test sequence.

If there is a tape in the drive, the drive ignores all outstanding SCSI commands, ejects the tape, reboots, and begins the Power-On-Self- Test sequence.

If the procedures above do not eject the cartridge from the drive, you may need to remove the cartridge manually, as described under Manually Removing a Cartridge on www.quantum.com/support.

Backup Failures

A backup failure can be caused by various reasons. The LTO-3 Tape Drive support the TapeAlert standard. The following troubleshooting steps start when software logs a TapeAlert message. You can view the TapeAlert message either on the main console screen or in the backup software’s log file. There may be more than one TapeAlert message per backup failure event.

1The TapeAlert message or backup log shows, “The operation has stopped because an error has occurred while reading or writing data which the drive cannot correct.
