• Determining when a cleaning cartridge has used all of its
available cleaning cycles
By default, the SuperLoader is configured to allow for host-
initiated cleaning. If automatic cleaning is disabled from the host,
the SuperLoader can be configured to manage the automatic
cleaning of the drive. This is done by enabling the “Auto Clean”
function. Please refer to the
Quantum ATL SuperLoader Automated
Tape Library User Manual
for information on how this is done.
In host-initiated cleaning mode, the host tracks all cleaning
cartridges and their use. When the SuperLoader Auto Clean
feature is enabled, a “cleaning slot” is allocated and the cleaning
cartridge is stored in this storage element. The SuperLoader
assumes that any cartridge stored in this location is a cleaning
cartridge and will attempt to use it as such.
The SuperLoader does not keep track of the number of times a
cleaning tape is used. Instead, it relies on the tape drive to report
when the tape has expired. When this happens, the superLoader
will notify the user via the front panel. The Auto Clean function is
automatically disabled until the user inserts a new cleaning tape
and re-enables the feature.
Element Status
Information
1
When the SuperLoader Auto Clean feature is enabled, the
allocated storage element is reported as inaccessible to the host.
This is done by setting the access bit to 0 in the Read Element
Status Storage Element Descriptor page.
Automatic
Cleaning
Operation
1
when the SuperLoader Auto Clean feature is enabled, the
SuperLoader checks if the drive needs cleaning after each
successful move from the drive. Therefore, each time the drive is
unloaded, it is checked.
Note:
There is no way for the host and SuperLoader to know
how the other is configured with respect to automatic
drive cleaning. It is up to the user to make sure only one
is enabled.
