– 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.

Loop 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.

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.

v Auto Clean - Use this menu item to enable the Auto Clean function. All cleaning

cartridges must have ″CLNxxxLx″ as 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.
