Cleaning Drives in the LSM

Cleaning Drives in the LSM
Drive cleaning can be initiated either by the operator or by the backup
application. The following information describes the functions the operator
needs to perform to clean the drives.
Operator-initiated cleaning is handled in one of two ways:
• For a SCSI interface
• For a serial interface
Before attempting to clean any drives in the LSM, make sure you know what
type of interface (control path) is installed at your site: SCSI or serial. If you do
not know, ask your service representative.
Note: The T9940 drive cannot be installed in a 9740 LSM if the library uses a SCSI
control path. Thus, the section entitled
“SCSI Interface” does not apply to
T9940 drives.
SCSI Interface
If your control path is SCSI, these items are true:
• You have the option of using the AUTO CLEAN function or cleaning the
drives manually.
• All drive cleaning is set up and controlled through the operator panel.
• The LSM automatically tracks the number of cleaning cycles performed by
the AUTO CLEAN function on any particular cleaning cartridge.
AUTO CLEAN Feature
The AUTO CLEAN feature can be enabled when your LSM is configured during
installation. When a drive requires cleaning, the robot receives a message
telling it to retrieve the cleaning cartridge from the cleaning cell in the LSM and
place it into the drive.
If AUTO CLEAN is not enabled, you must periodically look at the lights on the
drive. When the
Use Cleaning Cartridge
light is on, you must manually place a
cleaning cartridge into the drive.
See “Setting the Cleaning Cartridge Usage Count” on page 3-6 for more information and
procedures.
