Mode. The default control mode is Random.
Note:
If the I/E slot is enabled, the autoloader cannot be used in Mixed or Sequential
Mode.
The Sequential mode supports certain backup applications that do not manage
media. During backup, when one cartridge is read or written to the end of the tape,
the autoloader automatically returns that cartridge to its slot and loads the
cartridge from the next higher numbered slot to the tape drive to be read or written
to. This continues until the backup software stops accessing the drive or until all
the cartridges have been sequentially accessed.
