Summary

of

Changes

for

This

section

summarizes

changes

that

have

been

made

to

the

product

and

this

publication.

Technical

Changes

for

Version

1

Release

3

–

December

2003

The

following

changes

have

been

made

to

the

product

for

this

edition:

Tivoli

NetView

Web

console

IBM

Tivoli

Storage

Area

Network

Manager

now

supports

the

Tivoli

NetView

Web

console

in

a

limited

capacity.

The

IBM

Tivoli

Storage

Area

Network

Manager

dialogs

will

not

be

added

to

the

Tivoli

NetView

Web

console,

therefore

you

will

only

be

able

to

view

the

topology.

There

will

be

limited

viewing

of

the

topology

(no

property

information

will

be

available).

For

more

information,

see

“Using

the

Tivoli

NetView

Web

Console”

on

page

13

and

Support

for

the

Cisco

Virtual

SAN

(VSAN)

IBM

Tivoli

Storage

Area

Network

Manager

supports

the

Cisco

MDS

9000

Family

of

switches.

The

Cisco

switch

introduces

the

concept

of

the

virtual

SAN

(VSAN).

For

more

information,

see

“Virtual

Storage

Area

Networks”

on

page

38.

Tivoli

Enterprise

Console

Event

Filtering

IBM

Tivoli

Storage

Area

Network

Manager

has

improved

the

processing

of

Tivoli

Enterprise

Console

events

and

SNMP

traps.

Previously,

all

events

were

issued

without

any

kind

of

filtering.

Users

can

now

control

the

types

of

events

to

suppress

or

publish.

Events

that

are

redundant

will

automatically

be

suppressed.

For

more

information,

see

“Filtering

Events”

on

page

20,

Selectable

launch

of

device

applications

With

previous

versions

of

IBM

Tivoli

Storage

Area

Network

Manager,

you

could

launch

only

one

application

even

if

a

device

supported

multiple

applications.

Version

1.3

allows

you

to

choose

which

one

to

launch.

For

example,

for

a

Cisco

switch

you

can

choose

to

launch

either

Fabric

Manager

or

Device

Manager.

For

more

information,

see

“Launching

network

device

applications”

on

page

47.

IBM

Tivoli

Storage

Area

Network

Manager

Database

Snapshot

Support

To

help

troubleshoot

problems,

IBM

Tivoli

Storage

Area

Network

Manager

supports

a

database

snapshot.

The

database

snapshot

captures

the

current

state

of

the

SAN

topology.

You

would

use

this

function

at

the

request

of

customer

support.

For

more

information,

“Taking

a

database

snapshot”

storage

resources.

This

includes

devices

connected

to

host

systems

through

fiber-based

hubs,

bridges,

switches,

routers,

gateways,

and

directors.

Tivoli

Storage

Area

Network

Manager

Discovery

The

process

of

finding

resources

within

an

enterprise,

including

detection

of

network

topology,

is

called

discovery.

A

discovery

can

be

triggered

by

any

of

the

following

actions:

v

A

user

requests

a

discovery

(poll

now).

v

An

event

occurs

that

causes

IBM

Tivoli

Storage

Area

Network

Manager

to

perform

a

discovery.

v

A

scheduled

or

periodic

discovery

is

initiated.

A

scheduled

discovery

defaults

to

every

24

hours.

v

A

managed

host

or

SNMP

agent

has

been

added.

Tivoli

Storage

Area

Network

Manager

uses

the

following

methods

to

discover

your

network:

In-band

The

agent

on

each

managed

host

collects

information

about

the

host

machine

itself,

including

file

system

information.

Commands

are

sent

through

the

host

bus

adapter

(HBA)

cards

attaching

the

host

machine

to

the

SAN

to

gather

information

about

the

devices.

Out-of-band

The

manager

can

also

use

SNMP

queries

to

discover

information

about

selected

fabric

switches.

Management

information

base

(MIB)

information

is

collected

from

those

switches.

Each

method

has

its

advantages:

v

In-band

–

In-band

compliant

devices

can

discover

and

report

errors

for

adjoining

devices.

–

Agents

can

discover

and

manage

the

physical

and

logical

connections

from

the

switch

to

the

fibre-attached

storage.

–

Agents

can

discover

and

manage

fibre-attached

hosts

through

contact

with

their

HBAs.v

Out-of-band

–

If

a

Fibre

Channel

(FC)

path

is

down,

the

management

server

can

still

receive

errors

from

the

IP

path.

–

Discovery

is

not

affected

by

zoning.

Zoning

limits

in-band

requests

from

management

agents

to

discovering

only

those

end-points

within

the

zone.

There

are

two

types

of

discovery:

a

full

discovery

and

a

topology

discovery.

Table

1

on

page

3

explains

when

each

type

of

discovery

is

performed.

Discovery

Types

A

discovery

is

performed

when:

Full

Depending

on

the

number

of

objects

to

discover,

a

full

discovery

can

take

a

long

time

to

complete.

You

may

choose

never

to

run

a

full

discovery.

You

can

specify

when

to

run

a

full

discovery.

See

“srmcp

ConfigService

set”

on

page

84.

The

defaults

are:

v

IBM

Tivoli

Bonus

Pack

for

SAN

Management:

Never

run

a

full

discovery.

v

Tivoli

Storage

Area

Network

Manager:

Run

a

full

discovery

when

Poll

Now

is

specified

and

also

when

a

scheduled

discovery

starts.

v

A

user

requests

a

discovery

(poll

now)

v

A

scheduled

or

periodic

discovery

is

initiated

v

A

managed

host

is

added

Topology

This

type

of

discovery

takes

less

time

to

perform

than

a

full

discovery.

However,

a

topology

discovery

does

not

update

the

host-centric

or

device-centric

views.

These

Internet

SCSI

support

Tivoli

Storage

Area

Network

Manager

provides

basic

support

for

iSCSI

device

discovery

and

monitoring

through

Tivoli

NetView.

iSCSI

allows

SCSI

block

I/O

protocols

(commands,

sequences

and

attributes)

to

be

sent

over

a

network

using

the

TCP/IP

protocol.

The

SCSI

architecture

is

based

on

a

client/server

model.

Internet

SCSI

takes

this

model

into

account

when

providing

storage

requests

over

TCP/IP

networks.

The

client

(initiator)

is

typically

a

host

system

such

as

a

file

server

that

issues

read

or

write

requests.

The

server

(target)

is

a

resource

such

as

a

disk

array

that

responds

to

client

requests.

Tivoli

Storage

Area

Network

Manager

provides

the

following

support:

v

The

iSCSI

devices

that

have

iSCSI

MIB

and

SNMP

support

can

be

discovered

using

the

Tivoli

NetView

console.

The

discovery

process

automatically

creates

an

iSCSI

SmartSet

that

contains

the

iSCSI

devices

as

its

members.

v

The

Tivoli

NetView

nvsniffer

command

can

be

manually

issued

to

discover

iSCSI

devices.

The

command

specifies

a

configuration

file

that

identifies

which

devices

provide

iSCSI

support.

v

The

iSCSI

MIB

trap

definition

files

are

used

by

Tivoli

NetView

event

processing

such

as

event

filtering,

forwarding,

pager,

e-mail,

and

custom

actions.

v

The

iSCSI

MIBs

and

iSNS

MIBs

are

installed

with

Tivoli

Storage

Area

Network

Manager

and

the

administrator

can

then

load

the

MIBs

using

the

Tivoli

NetView

MIB

Loader

panel.

The

Tivoli

Storage

Area

Network

Manager

iSCSI

support

can

be

used

either

independently

or

in

conjunction

with

the

Internet

Storage

Naming

Service

(iSNS)

management

framework.

The

iSNS

protocol

is

a

protocol

for

managing

iSCSI

devices.

If

you

use

iSNS

with

Tivoli

Storage

Area

Network

Manager,

you

can

load

the

iSNS

MIB

files

and

use

the

Tivoli

NetView

MIB

browser

to

query

the

iSNS

server

and

view

the

status

of

iSCSI

devices.

For

more

information

about

iSCSI

and

iSNS,

see

the

following

Web

site:

http://www.ietf.org

iSCSI

discovery

You

can

start

iSCSI

discovery

through

the

Tivoli

NetView

menu.

Only

devices

that

support

the

iSCSI

MIB

and

SNMP

can

be

discovered

and

managed.

The

Tivoli

NetView

iSCSI

discovery

launches

an

nvsniffer

command

that

queries

whether

the

devices

are

iSCSI

devices.

You

can

use

Tivoli

NetView

to

discover:

all

iSCSI

devices,

all

iSCSI

initiators,

or

all

iSCSI

targets.

The

discovery

process

then

creates

a

SmartSet

that

contains

the

discovered

iSCSI

devices.

For

more

information,

see

“Discovering

iSCSI

devices”

on

page

42.

The

iSCSI

device

discovery

requires

that

you

enable

the

IP

discovery

of

Tivoli

NetView,

the

default

setting

has

IP

discovery

disabled.

For

information

on

enabling

IP

discovery

refer

to

IBM

Tivoli

Storage

Area

Network

Manager

Planning

and

Installation

Guide.

You

can

also

start

or

stop

the

iSCSI

discovery

from

the

command-line

interface

by

using

the

nvsniffer

command.

For

more

information,

see

“nvsniffer”

on

page

109.

You

can

control

Tivoli

NetView

IP

network

discovery

by

creating

a

seed

file.

A

seed

file

contains

a

list

of

host

names

or

nodes

within

your

administrative

domain.

Managing

file

system

security

Tivoli

Storage

Area

Network

Manager

security

is

dependent

on

a

secure

file

system

because

sensitive

information

such

as

certificate

keystore

passwords

and

configuration

properties

remain

on

the

manager

and

managed

hosts.

You

must

use

file

system

security

to

control

access

to

this

information.

v

A

Windows

installation

of

the

manager

and

agent

must

be

on

an

NTFS

file

system.

v

The

system

administrator

(root

user)

of

a

machine

must

always

have

access

to

the

local

file

system.

Therefore,

you

should

control

root

access

to

machines

running

Tivoli

Storage

Area

Network

Manager

software.

v

Many

files

should

have

restricted

access

for

security

reasons.

For

example:

–

services.properties

file

–

<install_dir>/lib

directory

–

setenv.bat

file

–

setenv.sh

for

the

AIX

manager

environment

–

server.xml

file
