Automatic Drive Cleaning
Quantum SuperLoader 3 Software Interface Guide 6
The SuperLoader 3 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 3 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 3 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
Descripto
r page.
Automatic Cleaning
Operation 1
When the SuperLoader 3 Auto Clean feature is enabled, the
SuperLoader 3 checks if the drive needs cleaning after each successful
move from the drive. Therefore, each time the drive is unloaded, it is
checked.
The movement of the cleaning tape is handled differently depending on
the SuperLoader 3 model.
If the move command that unloaded the drive was initiated from SCSI,
command complete is returned to the host when the move completes.
The cleaning tape is then moved from its storage slot to the drive. The
cleaning is performed and once complete, the cleaning tape is returned to
its storage location. If a SCSI command is received during this cleaning
process, a not ready check condition is reported (
SK=–2 ASC=30
ASCQ=03
).
