3 Click on the Device Maps link of the default
target.
4 Select the devices from the box on the right
hand side of the screen and drag to the
appropriate LUN on the left.
5 Click Submit.
If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
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 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.
You may use either of two methods to control
access to storage: Access Control Lists or CHAP
authentication.
Access Control lists: each target iqn has its own
access control. The iPBridge will check the
initiator’s iqn before allowing access.
CHAP to control access: different CHAP
account names and CHAP secrets are assigned to
each target.
Automatically configure multiple targets
1 If you are not already in the ExpressNAV
interface, type the IP address of your iPBridge
in a standard browser as found in
Using
ExpressNAV on page 27, click Enter Here,
type in your user name and password, and click
OK.
1 The Status page appears. Click on the Auto
Target Mgt menu item on the left side of the
screen.
2 Click on the Map each device to its own
target button.
A target name suffix will be added to the iqn of
each Fibre Channel device such as
vendorid-devicename-xxx
• vendorid is the Fibre Channel device
vendor ID
• devicename is the Fibre Channel device’s
inquiry device name.
• xxx is a device index
When the action is complete, the screen will go
to the iSCSI Target Management page.
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 are not already in the ExpressNAV
interface, type the IP address of your iPBridge
in a standard browser as found in
Using
ExpressNAV on page 27, click Enter Here,
type in your user name and password, and click
OK.
2 The Status page appears. Select the 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 Step 3 for each node you want to
configure.
8 If you are prompted to restart the iPBridge, go
to the Firmware Restart page and restart the
iPBridge.
