that

are

available

for

the

to

use

on

behalf

of

the

Step

3.

Starting

the

Storage

Agent

and

Verifying

the

LAN-free

Configuration

During

this

step

you

will

start

the

storage

agent

and

verify

the

LAN-free

configuration.

Step

3.1

Start

the

Storage

Agent

Start

the

storage

agent

by

changing

to

the

storage

agent

directory

and

issuing

the

following

command:

dsmsta

Step

3.2

Verify

the

LAN-free

Configuration

To

verify

that

you

have

configured

your

system

correctly

for

LAN-free

data

movement,

perform

the

following

procedure:

1.

Run

a

backup

operation

from

the

client.

Verify

that

the

backup

is

LAN-free

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.

The

QUERY

SESSION

on

the

Tivoli

Storage

Manager

server

should

show

a

very

small

amount

of

bytes

received

(metadata)

for

the

same

node.

If

the

node’s

session

exhibits

this

behavior,

and

you

receive

a

message

stating

that

the

backup

has

been

successful,

you

have

configured

your

system

correctly.

There

are

several

ways

to

use

the

QUERY

SESSION

command.

You

can

issue

the

command

on

the

storage

agent

console

if

the

process

is

running

in

the

foreground.

Or,

you

can

use

a

command-line

client

to

connect

to

the

storage

agent

on

the

administration

port

of

the

storage

agent.

You

would

use

the

same

administrator

ID

and

password

for

this

command

as

you

would

on

the

server.

2.

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

mount

and

message

is

displayed

on

the

storage

agent

console.

Notes:

1.

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.

2.

When

using

the

z/OS

data

manager

server,

volumes

for

sequential

access

storage

pools

that

support

LAN-free

data

movement

require

formatting

before

they

can

be

used.

LAN-free

sessions

will

fail

if

the

storage

pool

does

not

contain

any

formatted

volumes

and

does

not

allow

automatic

formatting.

details,

Tivoli

Storage

Manager

Administrator’s

Guide

Manager
