To remove mapping

Type

Route iSCSI [lun] Delete

Use the ExpressNAV interface

The ATTO Technology ExpressNAV, a browser-

based configuration tool, allows you to map

devices to the SCSI ports using a web-based GUI.

See

ExpressNAV provides web-based interface

on page 19.

To map devices automatically with ExpressNAV

1 From the ExpressNAV main menu, click on the

Mapping menu item on the left side of the

screen.

2Click AutoMap

All the CLI commands necessary to enable

mapping and the command

saveconfiguration

norestart

will be performed.

To map devices manually with ExpressNAV

1 From the ExpressNAV main menu, click on the

Mapping menu item on the left side of the

screen.

2 Select the devices from the box on the right

hand side of the screen and drag to the

appropriate LUN on the left.

3Click Submit.

All the CLI commands necessary to enable

mapping and the command

saveconfiguration

norestart

will be performed.

Multiple target mode

Multiple Target Mode breaks the single iSCSI

node of the iPBridge and replaces it with a much

more configurable mapping scheme. This new

mapping scheme allows you to segregate storage

into different iSCSI nodes within the iPBridge,

with each iSCSI target having its own set of

access criteria.

For example, if you have two servers and a library

with four tapes and a media changer, the default

mapping would provide both servers access to all

tapes and the media changer (single target mode).

If you configured multiple target mode, you

would be able to map some devices to one server

and other devices to the other server, requiring

separate usernames and passwords for access.

CAUTIONCAUTION

If actual storage is mapped to more than

one iSCSI target and a server has

authorization for both targets, the server

could show duplicate storage without any

warning to the user.

If multiple target mode is enabled, the

Automap,

Route, RouteDisplay

and

CHAP

CLI commands

behave differently. (Refer to

Ethernet commands

on page 35.)

After enabling

MultiTargetMode

through the CLI

command

set multitargetmode

, you may map

devices using the CLI commands

Automap or

Route

or by using the ExpressNAV interface. You

may also cycle power and the iPBridge will

automatically map all devices to separate nodes.

To control access, different CHAP account names

and CHAP secrets can be assigned to each target.

(Refer to

iSCSI commands

on page 37)

Use Command Line Interface

To map devices automatically with CLI

1 At the CLI prompt type

set MultiTargetMode enabled

Because current mapping will be deleted, you

are asked for confirmation to change mapping.

2 At the command prompt, type

AutoMap

• All the CLI commands necessary to enable

mapping and the command

saveconfiguration

norestart

will be performed.

• The iPbridge will its map itself as a device at

LUN 0.

• Each SCSI device will be placed at LUN 1

and a target name suffix will be added to the

iqn

bxtyy-vendorid-devicename

•

x

is the iPBridge SCSI port number

•

yy

is the SCSI device SCSI target ID

•

vendorid

is the SCSI device vendor ID

•

devicename

is the SCSI device’s inquiry

device name.
