command to the drive, the autoloader automatically removes the tape
cartridges from the drive and inserts the next available tape.
If the autoloader encounters a cleaning cartridge during the cycle, it will be
loaded into the drive as normal, but will be automatically unloaded after the
cleaning cycle.
– Random Mode: Random mode provides full autoloader functionality with
special automation software in the host computer. Tapes can only be loaded
to the drive from the front panel, host SCSI commands, or the optional
remote management card. The autoloader will not automatically load tapes as
it will in stacker mode.

Autodetect Mode (Factory Default):
In autodetect mode, the autoloader starts
in Stacker mode until it receives a SCSI “changer” command. The autoloader
then runs in random mode. The “changer” commands include the following:
INITIALIZE ELEMENT STATUS, READ ELEMENT STATUS, POSITION TO
ELEMENT, MOVE MEDIA, and EXCHANGE MEDIA.
With this operating mode, you must also select
Circular Mode On/Off . If the
circular mode option is ON , the autoloader will reload the first tape cartridge
after unloading the last tape cartridge. If circular mode is OFF and the last
tape cartridge has been unloaded, the autoloader stops operating until the
user loads additional tape cartridges.
Note: You must set autoload to OFF when in autodetect mode.

autoloader has been unplugged for an extended period and the autoloader
