Multiple target nodes
Multiple targets allow you to create a more 
configurable mapping scheme which can 
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 
node would provide both servers access to all 
tapes and the media changer (default target 
mode). 
If you configured multiple target nodes, you are 
able to map some devices to one server and other 
devices to the other server, requiring separate user 
names and passwords for access using various 
methods including Access Control Lists, iSNS 
and CHAP authentication. Consult with your 
network administrator and refer to Exhibit 3.1-1.
Note
If you map actual storage to more than one 
iSCSI target and a server has authorization for 
both targets, the server could show duplicate 
storage without any warning.
Automatically configure multiple targets
1
If you have not already, open an ExpressNAV 
session. For instructions, refer to 
2
From the ExpressNAV main menu, click on the 
Automatic Target Management menu item on 
the left side of the screen.
3
Click on the Map each device to its own 
target
 button.
A target name suffix is attached to the iqn of 
each SCSI device such as 
vendorid-devicename-xxx
•  vendorid is the SCSI device vendor ID
•  devicename is the SCSI device’s inquiry 
device name.
•  xxx is a device index
When the action is complete, the iSCSI Target 
Management 
page appears. 
If you are prompted to restart the iPBridge, go 
to the Firmware Restart page and restart the 
iPBridge.
Manually configure multiple target nodes
1
If you have not already, open an ExpressNAV 
session. For instructions, refer to 
2
The Status page appears. Select Auto Target 
Mgt 
menu item on the left side of the screen.
3
In the iSCSI Target Management page, type 
[name] in the Add an iSCSI target box
The name is a suffix appended to the standard 
IPBridge iqn name. The suffix name can be up 
to 24 characters. 
4
Click on the device map link of your target.
5
After the next mapping page opens, drag the 
boxes representing devices to the LUNs you 
want.
6
Click Submit.
7
Repeat from 
 for each node you want to 
configure.
