Library Operation Cleaning the Tape Drives Table 4-4 Drive Cleaning Issues Table 4-7 lists circumstances that can cause a drive cleaning message, C , to appear when a tape cartridge may be at fault. Note that: • Drives do not require scheduled cleaning maintenance. Excessive use of the cleaning cartridge can cause unnecessary wear on drive heads. • After 20 cleaning cycles, the cleaning cartridge must be replaced. Drive Cleaning Issues Relating to Tape Cartridges Problem A new data tape cartridge is used and a drive cleaning message is received. An older, frequently-used data tape cartridge is loaded and a drive cleaning message is received. An older, frequently-used tape causes a cleaning message to be displayed for the second time. Cleaning error remains after three cleaning cycles. Cause Solution Debris from the tape manufacturing process was deposited on the drive head. 1. Clean the drive using the library cleaning procedure on page 4-21. 2. If the message is displayed again within a short amount of time, return the cartridge for warranty replacement. Dust from frequent tape loads and unloads has most likely built up on the tape cartridge and was deposited on the drive head. 1. Clean the outside of the tape cartridge using a damp cloth. 2. Clean the tape drive using the tape drive cleaning procedure on page 4-21. The tape is most likely damaged. (Damaged cartridges can cause unnecessary use of the cleaning cartridge.) 1. Verify the tape is readable by clearing the error message. (Select the ONLINE REPAIR option from the control panel, and turn off power to the drive containing the tape, and then turn the drive power on again. See "Clearing a Drive Cleaning Error" on page 4-37.) 2. Try reading the tape again. If the tape can be read, back up data from the damaged cartridge to another tape cartridge and discard the damaged one. Debris is being deposited on the drive read/write heads. Contact an HP qualified service representative. The drive may need to be replaced. Library Operation 4-23
