Similarly, while a magazine is in the process of being removed, a
not ready check condition is reported (SK=02 ASC=04 ASCQ=07).
Once the operation is complete, by replacing the magazine with a
blank, a unit attention is reported (SK=06 ASC=3B ASCQ=12).
While one or both of the magazine bays are open, a not ready
check condition is reported (SK=02 ASC=04 ASCQ=03).

The SuperLoader monitors the ambient temperature within the
system. If the temperature exceeds the maximum safe temperature
for the media, the SuperLoader will disable all movement until the
temperature decreases below a safe threshold. While the
temperature remains excessive, SCSI commands that require
movement will fail (SK=04 ASC=0B ASCQ=01).
Automatic Drive Cleaning

There are two modes of automatic drive cleaning support
available:
• Host-initiated cleaning
• SuperLoader managed cleaning
Both modes provide automatic cleaning of the drive, but the first is
managed by the host and the second is managed by the
SuperLoader. These two modes are configured separately, and
only one should be enabled at any given time.
When automatic drive cleaning of the drive is enabled, either the
host of the SuperLoader is responsible for all cleaning functions
such as:
• Detecting when a drive requires cleaning
• Tracking and selecting cleaning cartridges
• Moving a cleaning cartridge to the drive
