Partitions on page 49). Cleaning slots are not assigned to specific
partitions. They are shared by all partitions within a library.
A maximum of four cleaning slots can be configured. Zero cleaning slots
are configured by default.
The drive cleaning interval, or number of motion hours between drive
cleanings, can also be configured. If no interval is set:
• The drive will not be cleaned in regular intervals.
• The drive will be cleaned when the drive issues a Tape Alert
indicating the drive needs to be cleaned.
• The drive will be cleaned when a manual cleaning is performed.
Automatic Cleaning intervals vary based on the manufacturer of the
drive:
• If AutoClean is enabled for HP drives, you must specify a cleaning
interval to ensure the drives are cleaned. Cleaning intervals are
specified in motion hours, which is the time in hours that the tape
moves over the drive head. HP LTO-4 drives will be cleaned every
100 hours, and HP LTO-5 and higher drives can be cleaned in
specified longer intervals.
• If AutoClean is enabled for IBM drives, the drives will continue to
clean at intervals that are determined by the drive. The selected
cleaning interval does not apply to IBM drives.
Cleaning slots do not need to be configured if you clean tape drives
manually. For more information about manual tape drive cleaning, see
Manually Cleaning Tape Drives
need to configure cleaning slots if you use host-based cleaning.
Cleaning slots are not visible to the host application. To use host-based
cleaning, configure zero cleaning slots in the library and set up your
host application to manage the cleaning process. See your host
application documentation for more information.
Note: If you decrease the number of cleaning slots from what is
currently configured, the extra slots become unassigned and
available to use as storage slots in new or existing partitions.
