Chapter 4: Operating the Autoloader

www.gateway.com

The system driven mode is the normal mode of operation. In this mode, the 
Operator’s Panel displays the status associated with the actions that were caused 
from commands issued through the drive's SCSI interface. Some of these 
actions, including loading, rewinding, and moving tape, appear.

When an Operator’s Panel button is pressed and released, the Operator’s Panel 
changes to interaction mode. In interaction mode, you can change settings for 
the autoloader.  

Interaction mode continues for three minutes after you stop pressing buttons, 
or the requested robotic action stops. The Operator’s Panel returns to system 
driven mode automatically.

The system driven mode has two operating modes — Random and Sequential. 
The operating mode used depends on whether automation software is 
controlling cartridges in the autoloader. Initially, the autoloader assumes you 
are not using automation software to control cartridge or drive activity. This 
is called sequential mode. If the autoloader detects that automation software is 
controlling tape drive activity, it switches to random mode automatically.

The following sections provide more information about sequential and random 
modes.

Random mode is the normal operating mode when a backup program is used. 
In random mode, the autoloader loads a cartridge into the drive when it receives 
the appropriate commands from the program. To use this mode, your backup 
program must support autoloaders. This support often requires an 
autoloader/library program module to be installed.

“SEQ” appears on the LCD when the autoloader is in 
Sequential Mode. No message appears during Random 
mode.
