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 I/O Station through slot 23) for loading into the drive.

-Autoload: Sequential mode with autoload mode ON loads the first available cartridge (slot with the lowest numerical value that contains a cartridge) automatically if the library powers ON with an empty drive.

-Loop: Sequential mode with loop mode ON loads the cartridge in the lowest numerical slot after the cartridge in the highest numerical slot has been filled and sent back to its home slot. This allows endless backup operations without user interaction.

-Starting Sequential Mode v Autoload Option:

If the Autoload option is set to ON (Configure Library Autoload), the accessor will load the first cartridge (cartridge located in the slot with the lowest numeric value) found in the storage inventory area into the drive upon power ON of the library. If the library powers on with a cartridge already in the drive, sequential mode will start with that cartridge unless the host issues a rewind and unload command to the drive. In that case, the next cartridge in sequence will be loaded into the drive.

If the Autoload Option if OFF, sequential mode must be started by selecting the Move Cartridges option (Control Move Cartridges) to load the first cartridge (or any cartridge) into the drive. Whatever cartridge is loaded into the drive, that is where the sequence starts from. For example, if a cartridge from the fifth lowest numeric storage slot containing a cartridge is loaded using the Move Cartridges option, after the host issues a rewind/unload command, the next cartridge loaded will be the cartridge from the next higher numeric slot. Cartridges need not be in contiguous slots.

vLoop Option:

If the Loop option is set to ON (Configure Library → → Loop), when the last cartridge (cartridge in the highest numeric slot) is unloaded and placed back into storage, the accessor will immediately start over again loading the first cartridge into the drive.

-Stopping Sequential Mode: To stop sequential mode, use the Move Cartridges option from the Control menu (Control Move Cartridges) to unload the drive. the next sequential cartridge will NOT be loaded. To restart sequential mode, use the same Control menu command to load a cartridge. The loading sequence will resume from that numeric slot in the cartridge inventory.

v Active Slots - the number of active slots you want to assign to each logical library.

Note: Slots can be reserved so that they are invisible to the host. It may be necessary to set the number of Active Slots to match the number of slots that are available to the ISV software.

vAuto Clean - Use this menu item to enable the Auto Clean function. All cleaning cartridges must have CLNxxxLxas part of the bar code.

The cleaning cartridge can be stored in any data cartridge slot.

Note: The universal cleaning cartridge has a bar code CLNUxxLx. This cleaning cartridge is used to clean all LTO generation tape drives.
