Setting the Change Mode
You can set the autoloader to either
Random
or
Sequential
. The default
change mode is
Random
.
In
Random
mode, you, or the backup software, can specify which
cartridge you want to use and where you want it to go. You will probably
use this mode the most.
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
sequentially accessed. The autoloader does not move the media until the
host requests the tape drive to unload the tape via 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 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 a user stops it.
To set the
Change Mode
:
1
From the main menu, scroll to
Configuration
, and then press
Enter
.
2
From the
Configuration
menu, scroll to
Change Mode
, and then press
Enter
. the mode options appear. A check mark appears next to the
currently enabled mode.

Do one of the following:
• To leave the mode the same, press
Escape
.
Note:
In
Sequential
mode, the medium changer does not appear in
the
Device Manager
. The medium changer will reappear in
Device Manager
if you return the system to
Random
mode. This
is to allow for operating systems that do not support multiple
LUNS.
