Tape drives need to be cleaned once every 30 motion hours.
Note – When cleaning the tape drive, use a Sun approved 8mm cleaning
cartridge.
Each drive keeps track of tape motion hours internally. When 30 tape motion
hours have elapsed, the following activities occur:
•
The top and bottom LEDs on the tape drive flash slowly. Depending on the
SCSI bus activity, the middle LED may also be flashing.
•
The tape drive informs the library that it needs cleaning. The library
displays "CTS needs cleaning" on the LCD main screen.
