Cleaning Drives in the LSM
3-8 Revision P 95693
Serial Interface
If your control path is serial, these items are true:
• You do not have the option of using the AUTO CLEAN function from the
operator panel.
• All drive cleaning is managed by and controlled through the host. The
manner which ACSLS (Automated Cartridge System Library Software)
handles automatic cleaning operations is defined in the ACSLS 5.3x System
Administrator’s Guide, PN 34767.
This guide explains that the LSM alerts ACSLS of the cleaning request and
ACSLS schedules the operation. The next time a mount request is received
for the given transport, a cleaning tape is first mounted to the transport and
the cleaning cycle completes before the requested data tape is mounted as
requested.
• ACSLS automatically tracks the number of cleaning cycles performed by any
particular cleaning cartridge.
Setting the Cleaning Cartridge Usage Count
In the event that all cleaning cartridges are expired, the original mount request
will be honored without the prior cleaning operation. For that mount and for
each subsequent mount to the uncleaned drive, a message will be posted in the
event log: No Cleaning Cartridge Available for the specified drive.
The ACSLS Messages document, PN 20177, explains the meaning of the message
in detail, recommending required action to add more cleaning cartridges.
Replacing Cleaning Cartridges
The “Cleaning Transports” section in the ACSLS 5.3 System Administrator’s
Guide, PN 34767 explains how to enter cleaning tapes into the library and how
to define them as cleaning tapes using the
Set Clean
command. This command
allows the user to specify maximum usage for the cleaning tape.
Unlocking the CAP and Removing Non-cleaning Cartridges
If the operator panel displays ONLINE CAP UNLK DISABLD. The CAP is
locked by the host.
Issue the command at the operator console that puts the LSM in the ONLINE -
PRESS EXE TO UNLK CAP

from it, you must first unlock it.
