• Barcode Label Alignment Reported to Host — configures the end of the bar code label characters
to report to the host application when reporting fewer than the maximum number of characters.
For example, when reporting only six characters of the bar code label
12345678
, if alignment
is left, the device will report
123456
. If alignment is right, the device will report
345678
. The
default is left.
• 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 ” on page 63. 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.
• Extended Mode Enabled — When the Library Extender is properly installed and extended mode
is enabled, the Libraries will operate as an extended library.
The following settings are configurable for each logical library:
• Library LUN Hosted By Drive — specifies the master tape drive for the logical library. The default
is the lowest numbered tape drive in the logical library. If a logical library has only one tape drive,
it is the master drive for the logical library. If a logical library has more than one tape drive, you
may specify the master. The number is the physical drive number.
• Library Mode — specifies the library mode for each logical library. The default mode is Automatic.
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 de-
signed for standalone drives only.
In Sequential mode, the logical library will only use the lowest-numbered tape drive in the logical
library.
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 con-
figuring Autoload mode, you must do one of the following for Autoload mode to take effect:
• Power cycle the device from the front panel.
