Appendix

A.

Administration

and

Configuration

Reference

This

section

provides

information

about

administering,

monitoring,

tuning,

and

connecting

the

storage

agent.

Starting

and

Stopping

the

Storage

Agent

The

storage

agent

can

be

configured

to

start

automatically

upon

system

reboot.

It

can

also

be

started

and

stopped

manually.

The

following

is

a

description

of

these

tasks.

Automating

the

Storage

Agent

Startup

The

storage

agent

is

configured

to

start

automatically

at

the

time

of

installation.

An

entry

is

made

to

the

inittab

to

enable

automatic

start

up.

The

storage

agent

automatically

restarts

and

runs

in

the

background

when

the

operating

system

is

rebooted.

During

the

installation

process,

the

etc/inittab

is

updated

with

the

following

command

to

enable

automatic

startup:

mkitab

autostgagnt:2:once:"/usr/tivoli/tsm/StorageAgent/bin/rc.tsmstgagnt

>/dev/console

2>&1

#Start

the

Tivoli

Storage

Manager

storage

agent"

If

you

decide

that

you

do

not

want

the

storage

agent

to

start

automatically,

you

can

issue

the

following

command

to

remove

the

statement

from

the

/etc/inittab.

rmitab

"autostgagnt"

Manually

Starting

and

Stopping

the

Storage

Agent

Start

the

storage

agent

by

accessing

the

storage

agent

directory

and

issue

the

following

command:

dsmsta

Stop

the

storage

agent

by

typing

the

following

command

at

the

command

line

prompt:

halt

Note

that

you

can

also

use

an

administrative

client

to

issue

commands

supported

by

the

storage

agent.

In

most

cases

it

is

not

necessary

to

halt

and

restart

a

LAN-free

storage

agent

to

pick

up

changes

from

the

data

manager

server.

However,

restarting

the

storage

agent

may

be

necessary

if

an

attempt

was

made

to

change

storage

pool,

library,

device

class,

or

drive

information

while

LAN-free

data

movement

was

in

process.

The

effects

on

LAN-free

storage

pools

resulting

from

such

an

attempted

change

are

not

critical

enough

to

create

serious

problems.

The

storage

agent

keeps

a

list

of

storage

pools,

libraries,

and

device

classes

in

memory

to

determine

potential

LAN-free

destinations.

Target

volume

selection

occurs

on

the

data

manager

server.

Certain

storage

pool

attributes

can

result

in

failed

requests

rather

than

the

desired

LAN

failover

by

the

storage

agent.

If

the

storage

agent

accurately

identifies

a

LAN-free

destination,

the

LAN-free

operation

will

most

likely

be

successful.
