After the drive Cleaning Required indicator illuminates, you
should wait no more than 24 hours for a low-activity time
then proceed as follows:
Step 1 Direct the host to remove any tape from the drive
and suspend all library activity.
Step 2 Set the library mode to Offline.
Step 3 Using the Operator Panel, go to the Clean Drives
screen (Main Menu Utils Drives Clean
Drives), and select the target drive. The library
selects a cleaning tape, inserts it into a drive, waits
until drive cleaning is complete, returns the
cleaning tape to its original location, increments the
usage counter, and displays the Requested
command is now complete message.
Step 4 Set the library mode to Online. The library is ready
for the host to take control and resume normal
operation.
Immediate AutoClean
You must have at least one good cleaning tape entered into
the library before beginning this procedure. For further
information, refer to Inserting a Cleaning Cartridge on page 25
or Declaring a Cleaning Cartridge on page 27.
During a move from a drive to a storage location, a drive
reports to the library, that it requires cleaning. If AutoClean is
enabled, the library puts the cartridge it is moving into a
storage slot, but does not report to the host that the move is
complete. Instead, the library selects the cleaning tape and
inserts it into the drive.
After the cleaning process is complete, the cleaning tape is
ejected and moved back to storage, the use counter
increments, and the library reports to the host that the move
is complete.
Advantages:
You do not have to set the library offline to clean a drive.
Library operation is not interrupted by the cleaning
operation.
This procedure checks the drive after every unload and
automatically cleans the drive only when necessary.
Note
Be aware that most
cleaning cartridges are
abrasive and burnish
the heads of the drive
they are cleaning.
Burnishing causes
wear on the tape drive
heads. Cleaning too
frequently can reduce
the life of a tape drive.
