Manager

server

is

a

library

client

or

library

manager.

If

the

server

is

a

library

client,

the

storage

agent

attempts

to

define

itself

to

the

library

manager

if

it

is

not

known

to

the

library

manager.

Step

5.2

Verify

the

LAN-free

Configuration

To

verify

that

you

have

configured

your

system

correctly

for

LAN-free

data

movement,

perform

the

following

procedure:

1.

Specify

the

DISPLAYLFINFO=YES

option

in

your

server

options

file.

This

will

allow

the

accounting

records

and

summary

table

entries

to

report

the

storage

agent

name.

Be

aware

that

this

option

may

cause

existing

outboard

automation

that

relies

on

the

summary

table

or

accounting

records

not

to

recognize

some

activities

for

a

given

client.

Make

sure

to

consider

how

this

may

impact

your

environment

before

setting

this

option.

2.

Issue

the

VALIDATE

LANFREE

command

to

determine

which

destinations

for

your

node

are

capable

of

LAN-free

data

movement.

For

those

nodes

that

are

not

capable

of

LAN-free

data

movement,

this

command

provides

an

explanation

as

to

why

they

are

not

capable.

You

can

use

this

information

to

correct

your

configuration

before

proceeding

to

the

next

step.

3.

Run

a

backup

operation

from

the

client.

4.

Ensure

the

following

if

you

receive

a

message

saying

that

the

backup

has

failed:

a.

The

Tivoli

Storage

Manager

server

is

running.

If

the

Tivoli

Storage

Manager

server

is

not

running,

the

storage

agent

will

not

start.

b.

The

client,

storage

agent,

and

server

are

communicating

with

each

other

as

expected.

c.

The

paths

to

the

drives

are

correctly

defined.

d.

All

drives

in

a

library

have

defined

paths

from

the

server.

Note:

If

you

retry

the

backup

operation

after

the

first

failure,

the

client

attempts

to

use

the

LAN

connection

for

data

movement.

The

client

will

continue

to

use

the

LAN

until

the

client

is

stopped

and

restarted.

Determining

Whether

the

Data

Movement

was

LAN-free

Use

the

following

guidelines

to

help

determine

whether

the

data

is

moving

on

the

LAN-free

path:

v

When

the

data

transfers

on

a

LAN-free

path,

a

message

displays

informing

you

that

the

client

is

starting

a

session

with

the

storage

agent:

ANR0415I

Session

session

number

proxied

by

storage

agent

name

for

node

your

node

name

This

message

confirms

that

LAN-free

data

movement

has

occurred.

v

You

can

also

view

the

backup

report

issued

when

backup

processing

completes.

When

LAN-free

data

movement

has

occurred,

the

number

of

″LAN-Free

Bytes

Transferred

is

greater

than

zero.

v

Monitor

the

QUERY

SESSION

output

against

the

node

that

is

running

the

LAN-free

backup.

Review

the

Bytes

Sent

and

Bytes

Received.

You

can

perform

this

action

by

using

a

Tivoli

Storage

Manager

administrative

command-line

client

to

login

to

the

Tivoli

Storage

Manager

server

and

storage

agent

to

verify

that

the

proper

sessions

have

been

established.

When

LAN-free

data

movement

is

occurring,

a

QUERY

SESSION

on

the

storage

agent

should

show

bytes

received

(displayed

as

Bytes

Recvd)

for

the

node

increasing

to

the

total

amount

of

data

being

backed

up.
