Emergency Reset and Emergency Cartridge Eject
7
In the unlikely event the LTO-2 Half-Height 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, see Problems During Backup/
Restore Operations .

Backup Failures 7 A Backup failure can be caused by various reasons. The LTO-2 Half-
Height Tape Drive supports 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.
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.
