Tape

Devices

Define

paths

on

the

server

using

the

device

names

as

seen

by

the

storage

agent

on

each

client

system.

Important:

Be

sure

that

the

device

names

are

what

the

storage

agent

sees

on

each

client

system.

Note:

The

DEFINE

PATH

command

must

be

issued

from

the

server

designated

as

the

library

manager.

For

example,

you

would

issue

the

following:

define

path

storagnt

drive1

srctype=server

desttype=drive

library=sanlib1

device=/dev/tsmscsi/mt1

See

the

Administrator’s

Reference

for

your

system

platform

for

additional

details

on

the

DEFINE

PATH

command.

Depending

on

the

operating

system

of

the

Tivoli

Storage

Manager

server,

there

may

not

be

a

quick

way

to

confirm

which

device

names

on

the

storage

agent

correspond

to

device

names

on

the

Tivoli

Storage

Manager

server

without

using

a

trial

and

error

method.

To

confirm

device

names,

you

should

work

with

one

online

drive

at

a

time,

and

cycle

through

the

storage

agent

device

names

until

a

successful

backup

can

be

run.

The

server

cannot

validate

PATH

information

that

is

provided

on

the

server

for

use

by

the

storage

agent.

Failures

can

occur

if

incorrect

device

information

is

provided

in

the

DEFINE

PATH

command.

You

can

also

specify

the

AUTODETECT=YES

option

when

defining

paths

on

the

server.

This

allows

the

serial

number

for

a

drive

or

library

to

be

automatically

updated

in

the

database

when

the

path

is

defined.

The

updated

serial

number

will

be

the

same

serial

number

that

the

drive

reports

to

Tivoli

Storage

Manager.

After

a

backup

is

completed

in

“Step

5.2

Verify

the

LAN-free

Configuration”

on

page

29,

you

can

issue

the

QUERY

DRIVE

command

to

obtain

information

that

will

help

determine

the

device

name

from

the

storage

agent.
