Cleaning Drives in the LSM
Replacing Cleaning Cartridges
When an LSM operating in an SCSI control path environment is in AUTO CLEAN
mode, the only method to use to replace an expired cleaning cartridge is by selecting the
Change Cln Cart utility from the main operator panel menu and following these
instructions.
Notes:
• Do not load cleaning cartridges through the door of the LSM because the cleaning
usage will not increment. You must use the
Change Cln Cart utility and then load
the cleaning cartridge through the CAP.
• In an LSM having both DLT and 9840 drives, make sure you specify the proper type
of cleaning cartridge when asked by the
Change Cln Cart
utility.
With microcode version 1.9.xx and lower:
The clean counter increments for each clean. When the clean counter is equal to the
set clean limit value (for example, 20 cleans for DLT cleaning cartridge), a
Cleaning Cartridge Used Up
message is displayed on the LSM operator
panel. This message disappears with the next operator panel message or SCSI
command.
If a drive indicates that it needs cleaning, the LSM continues to use an expired
cleaning cartridge, incrementing the clean counter for each cleaning mount. When an
expired cleaning cartridge is inserted into the drive, the drive will run the cleaning
tape to the end and detect that the cleaning cartridge is expired but will not reset the
clean indicator on the drive.
If the next tape successfully loads the drive clean indicator will disappear. Executing
Change Cln Cart
from the operator panel resets the library’s clean counter to 0.
With microcode version 1.10.xx and higher, same as above except:
When the clean counter is equal to the clean limit value, an asterisk (*) is displayed on
the right side of the top line on the operator panel to indicate that the cleaning
cartridge is expired. The asterisk remains on the display, even when other messages
display, until you execute
Change Cln Cart .
During early portions of a library initialization, the asterisk temporarily does not
display. However, once the library has been initialized, the asterisk reappears if the
clean counter exceeds the set clean limit.
