ATTO Technology Inc. iPBridge Installation and Operation Manual
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.
2 Click 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.
3 Click 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.
CAUTION CAUTION
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.
