Setup

Important

In Sequential mode, the medium changer does not appear in the Device Manager.

The medium changer reappears in Device Manager if you return the system to Random mode. This is to allow for operating systems that do not support multiple LUNS.

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 has sequentially accessed and used all available cartridges. The autoloader does not move the media until the host requests the tape drive to unload the tape through a SCSI unload command.

In Seq Cycle mode, which is an option of the Sequential mode, the autoloader automatically starts over with magazine slot 1 when the last cartridge is used (slot 16 or the highest filled slot). If this change mode is not set, the autoloader stops when the last cartridge available has been used. In Seq Cycle mode the autoloader continues to cycle until you stop it.

To set the Change mode:

1From the Main menu, click Configuration, then press ENTER. The Configuration submenu opens.

2Scroll to Change Mode, then press Enter. The mode options appear. A check mark appears next to the currently enabled mode.

3Do one of the following:

■To leave the mode the same, press Esc.

■To modify the change mode, scroll to the mode to you want, then press Enter. “Reboot to enable new mode” appears on the LCD.

4Press and hold the power button on the front panel until “System Shutdown wait 60 sec” appears on the LCD, then release it. “Power Off” then appears on the LCD and the autoloader shuts off.

5Press the power button again to turn on the autoloader. The new change mode is now in effect.

Sequential mode operations

If you enable Sequential mode, you must use the Sequential Ops submenu under the Commands menu to operate the autoloader after you reboot.

■The Start command lets you load the first cartridge.

■The Resume command lets you continue from the next unused slot, if you stopped the cycle.

■The Stop command lets you stop the cycle.

To start Sequential mode operation:

1From the Main menu, scroll to Commands, then press ENTER. The Commands submenu opens.

2Scroll to Sequential Ops, then press ENTER. The Sequential Ops submenu opens.

3Scroll to Start, then press ENTER. “Moving first tape to drive” appears on the LCD.
