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
Opening an
ExpressNAV session
on page 23
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

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.
