The Logical Settings box contains settings for the library access mode and the number of active cartridge
slots. Do the following:
v Library mode - The library mode can be set to Random or Sequential.
– Random - In random mode, the library allows the server's (host's) application software to select any
data cartridge in any order.
– Sequential - 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. See “Location coordinates and element addresses” on page 9.
Loop - Sequential mode with loop mode Enabled loads the cartridge in the lowest Column/Tier
cartridge position after the cartridge in the highest Column/Tier cartridge position is filled with
data and sent back to its home position. This mode allows endless backup operations without user
interaction.
Autoload - Sequential mode with auto load mode Enabled loads the first available cartridge (the
lowest Column/Tier cartridge position that contains a cartridge) automatically if the library powers
ON, or resets, with an empty drive. If the library powers ON with a cartridge already in the drive,
