Emergency Reset
and Emergency
Cartridge Eject
7
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).
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

Problems During
Backup/Restore
Operations
7
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.
1
The
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.
”
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.
