Configure Library Mode to set the
logical library access mode.
Configure the library access mode using the following settings:
•
Random Mode — In random mode, the library allows the server’s (host’s)
application software to select any data cartridge in any order.
• Sequential Mode — In sequential mode, the library’s firmware predefines the
selection of the cartridges. After initialization, the firmware causes the library to
select the first available cartridge found (counting from the lowest Column/Tier
position through the highest cartridge position in your library) for loading into the
drive.
–
Loop — Sequential mode with loop mode ON loads the cartridge in the lowest
Column/Tier cartridge position after the cartridge in the highest Column/Tier
cartridge position has been filled and sent back to its home position. This allows
endless backup operations without user interaction.
– Autoload — Sequential mode with autoload mode ON loads the first available
cartridge (the lowest Column/Tier cartridge position that contains a cartridge)
automatically if the library powers ON with an empty drive.

Configure Date/Time to set the date and
time on your library manually after a power disruption and when daylight savings
time starts and ends. The date is set in MM/DD/YYYY format, and the time is set in
24-hour HH:MM:SS format.
The current date and time can also be controlled automatically using a network-based
Network Time Protocol (NTP) server. For more information, see “Configuring
Network Settings” on page 4-22.
