Setting the master drive (Configuration > Set Master Drive)
CAUTION: If you change the SCSI ID, you might need to cycle power on the host server and
reconfigure your backup software before you can use the device.
To set the master drive:
1. From the Home screen, press Previous or Next until the screen displays Configuration. Press
Enter to select.
2. Press Previous or Next until the screen displays Set Master Drive. Press Enter to select.
3. Enter the administrator password if prompted.
4. Press Previous or Next until the screen displays either Master Drive Drive 1 or Master Drive
Drive 2.
5. Press Enter to select the displayed configuration. The screen displays either Drive 1 Set to
Master, or Drive 2 Set to Master, and the Ready LED blinks.
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.
The operator begins the sequence by loading the desired tape into the tape drive. When a tape
is unloaded for any reason, the device automatically removes the tape from the drive, returns it to
its original slot, then loads the tape from the next available higher numbered slot.
To further determine how you want tapes loaded into the tape drive while in Sequential mode,
you can set the Loop and Autoload options.
When Autoload mode is set, the device automatically loads the cartridge from the
lowest-numbered full slot into the tape drive. It then follows standard sequential operation.
After configuring Autoload mode, you must do one of the following for Autoload mode to take
effect:
Power cycle the device from the front panel.
Reboot the device from the RMI Support: Reboot screen.
Move the lowest-numbered cartridge to the drive before starting the backup application.
If the mailslot is enabled, the lowest cartridge location will be in the mailslot.
When Loop mode is on, the original first cartridge in the sequence is reloaded after the device
has cycled through all available cartridges. If Loop mode is off and the last cartridge has been
unloaded, the device stops loading cartridges until you load another manually.
