Multiple Target Nodes; Automatically Configure Multiple Targets; Manually Configure Multiple Target Nodes - ATTO Technology iPBridge 2600 Installation And Operation Manual

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
nodes would provide both servers access to all
tapes and the media changer (default target
mode).
If you configure 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 2.1-1,
iSCSI commands on page 51 and the
on page v of the Appendix.
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 are not already in the ExpressNAV GUI,
type the IP address of your iPBridge, as found
in Discover the IP address
standard browser and press Enter.
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. See Exhibit 2.1-2 on page 10.
The iPBridge maps itself as a device at LUN 0.
A target name suffix is added to the iqn of each
device such as
vendorid-devicename-xxx
• vendorid is the device vendor ID
• devicename is the device's inquiry device
name.
• xxx is a device index
When the action is complete, the screen returns
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 GUI,
type the IP address of your iPBridge, as found
in Discover the IP address
standard browser and press Enter.
2 From the ExpressNAV main menu, click on the
Automatic Target Management 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
