Attachment

considerations

This

section

provides

overview

for

attaching

storage

unit

iSCSI

Gateway

host.

Attachment

overview

the

iSCSI

Gateway

host

This

topic

provides

attachment

overview

the

iSCSI

Gateway

host.

The

iSCSI

Gateway

router

provides

access

storage

unit

fibre-channel

storage

over

Ethernet

(LAN

based)

network.

Host

servers

attached

through

Ethernet

connections

can

attach

assigned

LUNs

much

the

same

way

fibre-channel

attached

servers

using

host

bus

adapters.

LUNs

can

shared

dedicated.

Note:

When

you

configure

the

storage

unit

for

host

attachment,

you

can

define

the

worldwide

port

name

host

type.

For

example,

you

can

define

the

SN5420

iSCSI

Gateway

host

type.

You

can

identify

each

host

entry

the

scsirouter

list.

You

can

present

the

storage

unit

LUNs

the

SN5420,

and

you

can

use

the

scsirouter

list

manage

host

assignment.

Attachment

requirements

for

This

section

lists

the

requirements

for

attaching

the

storage

system:

Ensure

that

you

can

reference

the

documentation

for

your

host
