HP StoreEver MSL2024, MSL4048, MSL8048, and MSL8096 Tape Libraries User and Service Guide (AK378-96059, December 2012)

NOTE: Barcode labels longer than eight characters might scan incorrectly, especially if they
are not high-quality labels.
• 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” (page 60). 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.
• Enable Extended Mode— 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 designed 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.
