Legacy

ACSLS

Data

Migration

and

Coexistence

Note:

For

the

latest

information

concerning

migration

and

coexistence,

see

the

Tivoli

Storage

Manager

README.

If

your

environment

consists

of

Tivoli

Storage

Manager

storage

pools

associated

with

an

ACSLS

library

type

and

an

ECARTRIDGE

device

type,

the

library

can

be

updated

with

the

SHARED=YES

option

to

enable

LAN-free

data

movement.

If

your

environment

consists

of

Tivoli

Storage

Manager

storage

pools

associated

with

an

ACSLS

library

type

and

a

GENERICTAPE

device

type,

data

migration

is

required

rather

than

coexistence

because

Tivoli

Storage

Manager

ACSLS

shared

library

support

cannot

co-exist

with

external

library

support.

See

the

″Configuring

Storage

Devices

chapter

in

the

Administrator’s

Guide

for

detailed

information

on

how

to

migrate

from

an

external

library

environment

to

a

shared

ACSLS

library

environment.

Data

Migration

Data

migration

of

ACSLS

to

external

library

support

is

necessary

only

when

Tivoli

Storage

Manager

ACSLS

shared

library

support

is

not

possible

in

your

configuration.

The

only

situation

where

ACSLS

shared

library

support

is

not

possible

is

when

your

environment

does

not

contain

a

Tivoli

Storage

Manager

server

installed

on

AIX,

Solaris,

or

Windows

to

serve

as

the

library

manager.

Migrate

the

existing

data

from

existing

(old)

storage

pools

to

new

storage

pools

associated

with

the

appropriate

policy,

device

class,

and

library

definitions.

Migration

of

data

also

allows

the

entire

environment

to

be

LAN-free,

providing

better

performance

and

better

utilization

of

tape

drives

and

media.

Figure

10

on

page

52

displays

the

normal

migration

path

from

an

old

storage

pool

containing

the

data

associated

with

the

ACSLS

library

type

to

a

new

storage

pool

associated

with

an

EXTERNAL

library

type

and

an

ECARTRIDGE

device

class.
