Sequential mode
Sequential mode is used when autoloader software is not available. In sequential
mode, the autoloader loads and unloads tapes automatically. You specify which
tape you want to be loaded first by using the autoloader Operator’s Panel
controls. (For more information on loading cartridges, see “Loading and
unloading a cartridge” on page 28.)
When the first cartridge is full or unloaded, the autoloader removes the
cartridge from the drive automatically, returns it to its original slot, and loads
another cartridge into the next higher numbered slot that is available. For
additional control over loading cartridges in sequential mode, you can set
Circular and Autoload options from the autoloader’s front panel.
Circular mode
This option is accessed from the Configuration menu. When circular mode is
enabled, the autoloader reloads the original first cartridge in the sequence after
it cycles through all available cartridges. If circular mode is disabled, the
autoloader stops loading cartridges after the last cartridge has been unloaded
and waits until you load another cartridge manually.
Autoload mode
This option is accessed from the Configuration menu. When autoload mode is
enabled, the autoloader automatically loads the cartridge from the lowest
numbered full slot into the tape drive when you turn the autoloader on. It then
follows standard sequential operation.
Caution Use caution with circular mode because it can overwrite
data on previously written cartridges.
