Figure 40 System Configuration
The following information is displayed:
1.
Library Master Drive:
The drive number that will host the library’s logical unit number (LUN)
2.
Library Mode:
One of three behavior modes - Random, Sequential or Automatic
•
<Random>
In random mode, the library does not automatically load tapes into the
tape drives. The random mode is used with a full featured or a media
changer-aware backup application and is the most common mode of
operation.
•
<Sequential>
In sequential mode, the library automatically loads and unloads tapes
from the tape drive. The sequential mode is used when the backup
software is not media changer-aware or was designed for standalone
drives only.
•
<Automatic>
This is the default mode. In automatic mode, the library switches from
sequential mode into random mode when it receives library SCSI
commands through its unique LUN.
In sequential mode, the user can set the <Loop> and <Autoload>
options. In the auto load mode, the library automatically loads the
tapes from the lowest-numbered full slot into the tape drive. In
loop mode, the original first tape in the sequence is reloaded after
the library has cycled through all available tapes.
3.
Active Slots:
In this field the user can select the number of slots in the library that are
available to the backup software.
