Removing a Tape Cartridge
To remove a tape cartridge:
1. Ensure that the Ultrium Tape Drive is powered-on.
2. Press the unload button. The drive rewinds the tape and partially ejects the
cartridge. The status light flashes green while the tape rewinds, then goes out
before the cartridge partially ejects.
3. After the cartridge partially ejects, grasp the cartridge and remove it.
If you are unable to remove the cartridge, see “Manually Removing a Tape
Cartridge” on page 73. Whenever you unload a tape cartridge, the tape drive writes
any pertinent information to the cartridge memory.
Cleaning the Drive Head
Attention: To clean the drive head, use the IBM LTO Ultrium Cleaning Cartridge
or an IBM-approved cleaning cartridge.
Clean the drive head whenever C displays on the single-character display and the
status light is solid green. To clean the head, insert the cleaning cartridge into the
tape load compartment (see Figure 9 on page 26). The drive performs the cleaning
automatically. When the cleaning is finished, the drive ejects the cartridge. The IBM
LTO Ultrium Cleaning Cartridge is valid for 50 uses.
Placing the Drive in Maintenance Mode
The Ultrium Tape Drive can run diagnostics, verify write and read operations, verify
a suspect tape cartridge, update its own firmware, and perform other diagnostic and
maintenance functions listed in Table 7 on page 29. The drive must be in
maintenance mode to perform these functions.
Attention: Maintenance functions cannot be performed concurrently with read or
write operations. While in maintenance mode, the tape drive does not accept SCSI
or Fibre Channel commands from the server. The tape drive does accept RS-422
interface commands.
To place the drive in maintenance mode:
1. Make sure that no cartridge is in the drive.
2. Within a 1-second interval, press the unload button three times. The status light
becomes solid amber, which means that the drive is in maintenance mode.
Note: If a cartridge is in the drive, it will eject the first time that you press the
unload button and the drive will not be placed in maintenance mode. To
continue placing the drive in maintenance mode, remove the cartridge
and repeat this step.
