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.

Autoload

Option:

–

If

Autoload

option

is

set

to

ON

(Configure

→

the

accessor

will

load

the

first

cartridge

(cartridge

located

the

slot

with

the

lowest

numeric

value)

found

in

the

storage

inventory

area

into

the

drive

upon

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

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.

v
