Now that the network configuration for the iSCSI Target has been
configured - the next step is to connect to the iSCSI Target, as follows:
Once the iSCSI Bridge configuration has been completed, click on
Start > Control Panel > iSCSI Initiator
Next, select the Discovery tab.
On the Discovery tab window, select Add from the Target Portals section.
Enter the IP Address from iSCSI Bridge connection.
(Even though there are two NIC connections on the iSCSI Bridge, one connection
can be configured. If both iSCSI connections are configured, then use the first
IP Address entered into the iSCSI Bridge connection.)
The Port of 3260 is entered by default.
While on this window, select Advanced.
In the "Connect by using" section, for Local adapter, the drop-down menu can be
set to Default or Microsoft iSCSI Initiator.
Typically, if there are other iSCSI Initiators, either software or hardware, then the selection
of the Microsoft iSCSI Initiator might need to be selected.
(The iSCSI Bridge only accepts software iSCSI Initiators.)
Addition, if CHAP (Challenge Handshake Authentication Protocol), is being implemented
on the iSCSI Bridge, you can enable the CHAP logon information.
After configuring this window, select OK until back to the Discovery tab.
Once on the Discovery tab, you should see that the IP Address and Port have been found.
If not, an error should have appeared advising that the connection could not be made.
Next, select the Targets tab.
If done correctly, there should be found devices on this window.
In this example, the TL2000 Tape Library has two LTO6 tape drives.
As a result, there are three devices found - a medium changer, and two tape drives.
Select the first target, and click on Log On.
On the "Log On to Target" window, select or checkmark the
"Automatically restore the connection when the system boots".
Do not select "Enable multi-path".
Click on OK, when done.
If you click on Advanced on the "Log On to Target", you will see a familiar window.
Configure any changes, and select OK until back to the Targets tab.
If done correctly, the select device should have a Status of Connected instead of Inactive.
For each device listed that has an Inactive status, follow the previous steps until each device
has a "Connected" status.
Once done, on the Targets tab, all of the iSCSI Bridge devices should have a Connected status.
Once done with the Microsoft™ iSCSI Initiator setup, you should see the medium changer
and tape drive(s) within the Microsoft™ Device Manager.
Device Manager can be reached through Start > right click on My Computer > Manage > Device Manager.
Or it can be reach in other ways as well.
Creating Multiple Connections (Optional)
The following process is to create multiple connections for iSCSI Sessions.
The main policies that should be used are "Round Robin" and "Fail Over Only".
The Load Balance Policy, which will be shown later, specifies how the data is
distributed over multiple connections.
For most purposes the Round Robin policy will provide the greatest performance increase.
For this process, it will require an addition network connection to be setup.
The following is the typically process to add multiple connections using the Windows 2003®
iSCSI Initiator process:
If the user wishes to create multiple connections to an iSCSI Session, return to the Session
tab in the Target Properties window. Click on the Details button shown below.
Click on the Connections button and a window should appear.
To add a new connection to a session, click on the Add button and a new window should appear.
Now click on the Advanced button to see the Advanced Settings.
Select the Source IP-address and the Target Portal that you wish to connect too via the pull down menus in
the "Connect by using" section. When setting up multiple connections you ideally want to connect to
different ports and different network interfaces.
In this example we have connected to 192.168.130.117/3260
as the leading connection and the second connection will be 192.168.131.117/3260.
While on this screen, CHAP can be setup; but, this is optional and not a requirement.
When done, click on OK.
Now, on the Session and Properties tab for the Target properties window -
you should see two connections. Select OK until you are out-of-the-screens.
Now for each device listed on the Targets tab for your TL2000 / TL4000 iSCSI connection,
you will need to go through the previously listed steps for the multiple sessions,
At this point, you should still only see one medium changer and the tape drives
within the Device Manager. In this example, one should only see one medium
changer and two tape drives within Device Manager.
