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

7

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.

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.
