IBM 4mm DDS-2 Tape Autoloader, Инструкция по установке и эксплуатации

Страница: 35 / 52

controlled by the command or application, the operator should cause the unload by
pressing the Eject button (making sure that the application or command is finished
with the cartridge). The magazine will eject when operating in this single cartridge
mode. Re-insert the Magazine, and select the next or appropriate cartridge to
continue or to initiate a new command or application. Don't reuse the cartridge just
unloaded if it contains important data (such as your 'backup' data).
Modes
The Autoloader can operate in two modes, sequential or random.
Sequential
In sequential mode, the Autoloader does not depend on host implementation of
changer commands. You can select which cartridge to initially load by using the
Select and Load buttons on the front panel. Refer to “Controls and Indicators” on
page 5-8 for button and indicator location. When a cartridge is ejected from the
drive following a host UNLOAD command, the Autoloader will automatically load the
next available cartridge from the magazine into the drive.
Random
In random mode, the host views the Autoloader as two devices:
Ÿ
A changer mechanism to which SCSI Medium Changer commands can be sent.
Ÿ
A tape drive to which SCSI Sequential Access commands can be sent.
The controlling host computer therefore has full random access to any cartridge.
Most PC backup/restore applications automatically load, unload, and clean the
Autoloader using the random access mode. Refer to your backup/restore software
instructions for additional details.
