Ignore Barcode Media ID — when disabled, the barcode Media ID on the tape cartridges
will be checked by the device. The device will only allow appropriate tape cartridges to be
loaded into tape drives. The barcode Media ID is the last two characters of the barcode. For
example, an LTO-4 labeled cartridge will not be allowed to move into an LTO-3 tape drive.
See
Backward read compatibility (page 33) . When Ignore Barcode Media ID is enabled, the
device will move any tape to any tape drive. If the cartridge is incompatible with the tape
drive, a message will be displayed. HP strongly recommends that all tape cartridges have
barcodes with the correct Media ID.
•
Magazine access using front panel - Admin password required — when enabled, the
Administrator password is required to remove the magazines from the front panel. When
disabled, the magazines may be removed using the operator control panel without entering
a password. The default is to require the Administrator password.

Select Language — The language option affects the text on the RMI, the error messages, and
the help pages. It does not affect the OCP menus, which will always be in English.
•
Autoloader LUN Hosted by Drive — will always be 1 because the Autoloader only has one
tape drive.

Autoloader Mode — Random, Sequential, Automatic, Autoload, Loop
The device supports three behavior modes: Random, Sequential, and Automatic. The device
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.
Random mode — In Random mode, the device does not automatically load tapes into the
tape drives; 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.
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.
