Setting behaviors (Configuration > Library Behavior)
The Library supports three behavior modes: Random, Sequential, and Automatic. The Library
automatically detects the required mode from the series of SCSI commands it receives; however, you
can also change the mode. Choose the operating mode based on the capabilities of the software
controlling the tape cartridges. The Library mode can be set independently for each logical library.
Access to this feature requires the administrator password.
Random mode : In Random mode, the device does not automatically load tapes into the tape drive;
it waits for commands from the software or operator to load and unload tapes. Random mode is used
with a full featured or a robotics-aware backup application and is the most common mode of operation.
Your backup software must support robotics, which may require an additional software module.
Sequential mode : In Sequential mode, the device automatically loads and unloads tapes from the
drive. Sequential mode is used when the backup software is NOT robotics-aware or was designed
for standalone drives only.
In Sequential mode, the Library will only use the lowest-numbered tape drive.
