Clean the Drive
■ Clean the Drive
When the clean indicator on the operator panel (Figure 1-12 on page 1-11 or
Figure 1-13 on page 1-13 for the CSL) lights, it means that read/write errors
occurred or a specific length of tape has passed over the read/write head. The
9840 Tape Drive write/read head assembly should be cleaned by a cleaning
tape cartridge as soon as possible.
CAUTION:
Do not wet-clean (chemical-clean) a 9840 Tape Drive.
Do not clean the drive unless the clean indicator lights. Cleaning more
frequently might damage the read/write head.
Clean the drive with the drive offline or online. Use the 9840 cleaning cartridge
with the letter U in the media ID area (a dry-cleaning cartridge).
To clean the tape drive:
1. Unload the data cartridge tape if necessary.
2. Insert the cleaning cartridge in the drive.
Notes:
1. A CHK xxxx message means a cleaning cartridge failure, where the
notation “xxxx
” is a four-character hexadecimal fault symptom code
(FSC
). Try a different cleaning cartridge.
2. A 9840 cleaning cartridge is limited to 100 cleanings. If the drive
ejects the cleaning cartridge and displays Exp CLcart, the
cartridge is used up. Discard the cleaning cartridge and use a new
one.
3. Observe:
a. The green
activity indicator flashes to indicate cleaning is occurring.
b. The cleaning cartridge ejects and the
clean indicator turns off when
cleaning is complete.
4. Remove the cleaning cartridge.
