properly erase an LTO data cartridge and will permanently damage the cartridge.
Resetting the tape drive (FC 5755)
You might need to reset your tape drive. Use the procedure in this topic to perform this task.
Use this information to reset your half-high LTO-2 tape drive, without impacting server operation. Please
allow up to 2 minutes for the entire tape drive process to complete.
Attention: Resetting a tape drive before the current backup operation has completed may cause loss of
customer data.
To reset the tape drive, follow these steps:
1. Press and hold the eject button for 7 seconds, until the green Ready LED starts flashing rapidly, then
release the button. The Ready LED will continue flashing, indicating that the drive is waiting for a
cartridge to be inserted.
2. Press and release the eject button. The green Activity LED will begin flashing rapidly.
3. Double-click the eject button. The Activity LED will continue flashing slowly while the reset function
is in progress. When the reset function is complete, the tape cartridge will remain in the drive and the
Ready LED will be lit. Allow up to 2 minutes for the reset function to complete.
Note: A solid amber Cleaning LED light indicates that the reset is complete, but the tape unit requires
cleaning. Clean the tape unit by inserting an IBM Universal LTO Cleaning Cartridge (part number
35L2086).
After the reset function completes, the tape unit is restored to normal operating mode. To remove the
cartridge, press the eject button.
