Contamination by loose

debris.

Non-acclimated media.

Tape cartridge is

incompatible.

Expired cleaning cartridge.

Bad/defective/contaminated

media.

Tape cartridge movement

Tape cartridge stuck in tape

drive.

Tape stuck in storage slot.

SOLUTION

Avoid contamination by ensuring that the library is installed in a clean,

contamination-free environment. Tapes should be stored vertically in

their plastic cases. Clean the tape drive(s) as needed.

A tape should be acclimated for at least 24 hours before being used,

particularly if it has been stored at a substantially different

temperature or level of humidity than the library.

Use only tapes that are compatible with the tape drive type.

See Section 2.15

Make sure you are using an Ultrium universal cleaning tape. (max. 50

cleans)

If the <Media Attention> LED is cleared and the tape drive is clean, but

the LED immediately re-displays each time a particular tape is loaded,

that tape should be suspected of being defective.

 Export the tape and load a known good tape. In some cases, a tape

can be worn out, have a defective tape memory, or have been

formatted as a Firmware Upgrade Cartridge.

 Any tape that is suspected of being defective or contaminated

should NOT be reused in any drive.

 Power cycle the library, allow it to complete initialization, which in

rare cases can take as long as 10 minutes, and then retry unloading

the tape using the library operator control panel.

 Allow the tape drive to complete all operations. This may take as

long as ten minutes if you reset or cycle power to the library while

the cartridge is positioned at the physical end of the media.

 Make sure that the backup software is not reserving the slot or

preventing the tape drive from ejecting the tape. The backup

software needs to cancel the reservation and any hold it has on the

tape drive. Temporarily disconnecting the library from the host

server and power cycling eliminates the host and its software as a

problem source.

 Contact your service representative.
