iSCSI Bridge Setup


Firstly, for the PowerVault TL2000 / TL4000 Tape Library
the iSCSI bridge has to be installed into the library.

Use the following link, if you need to installed the iSCSI Bridge(s)
into the tape library:

1Gb iSCSI to SAS User's Guide

Note:
The above hyperlink will also show how to setup and configure the iSCSI Bridge, and the Operating System initiator as well.
Notice:
Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage equipment.

Note:
Consider updating the iSCSI Bridge firmware before implementing this setup.

Network Configuration


Next, the iSCSI Bridge has to be configured to interact
with iSCSI Initiator provided by the Operating System.

Use the following link, if you have not configured your PowerVault
TL2000 / TL4000 iSCSI Bridge:


PowerVault TL2000 / TL4000 - How to Configure the iSCSI Bridge
Note:
If you have purchased a Remote Install, or want assistance with this process, please contact Dell Technical Support for assistance.

A service fee might be required for technical assistance for the iSCSI Bridge and iSCSI Initiator setup and configuration.

With this article, we are showing a basic setup with
Windows 2003 Server, and using the Microsoft iSCSI Initiator software.

In this section, we will start with the network configuration, as follows:
  1. Click on Start > Control Panel > Network Connections.
    (There is more than one way to access the Network Connections window.)

    Figure 1 - iSCSI W2K3 Control Panel NIC Connections
  2. Within this window, select a network interface (NIC) that will be used to
    connect to the iSCSI Bridge connection.

    Figure 1a - iSCSI W2K3 - NIC Connections

    This should be a 1000Mb/s connection. If it is a 10/100Mb/s connection,
    it will limit the performance dramatically.

    In this instance, Local Area Connection 2, will be used.
  3. Right click on the network connection > Properties > Connection Properties.
    In this instance, it will be the Local Area Connection 2 Properties.

    Figure 3 - iSCSI W2K3 LAN Connection
  4. Select Internet Protocol (TCP/IP) > Properties > Enter the following, as necessary:

    Figure 3 - iSCSI W2K3 TCP Properties
    1. IP Address
    2. Subnet mask
    3. Gateway (if necessary)
  5. After this, if the initial setup of the iSCSI Bridge has not been completed,
    please return the Web Interface of the iSCSI Bridge, and complete the setup.
    Use the following link, as necessary:

iSCSI Initiator
Configuration


Now that the network configuration for the iSCSI Target has been
configured - the next step is to connect to the iSCSI Target, as follows:
  1. Once the iSCSI Bridge configuration has been completed, click on
    Start > Control Panel > iSCSI Initiator

    Figure 4 - iSCSI W2K3 - Control Panel iSCSI Initiator
  2. Next, select the Discovery tab.

    Figure 5 - iSCSI W2K3 iSCSI Initiator
  3. On the Discovery tab window, select Add from the Target Portals section.

    Figure 6 - iSCSI W2K3 iSCSI Initiator Discovery
  4. 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.)

    Figure 7 - iSCSI W2K3 iSCSI Add Target

    The Port of 3260 is entered by default.
  5. While on this window, select Advanced.

    Figure 8 - iSCSI W2K3 iSCSI Advanced
  6. 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.)

    Figure 8 - iSCSI W2K3 iSCSI Advanced

    Addition, if CHAP (Challenge Handshake Authentication Protocol), is being implemented
    on the iSCSI Bridge, you can enable the CHAP logon information.
  7. After configuring this window, select OK until back to the Discovery tab.
  8. 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.

    Figure 9 - iSCSI W2K3 - iSCSI Discovery Target_Found
  9. Next, select the Targets tab.

    Figure 10 - iSCSI W2K3 - iSCSI Targets
  10. 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.
  11. Select the first target, and click on Log On.
  12. On the "Log On to Target" window, select or checkmark the
    "Automatically restore the connection when the system boots".

    Figure 10a - iSCSI W2K3 - Log On Target

    Do not select "Enable multi-path".

    Click on OK, when done.
  13. 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.

    Figure 11 - iSCSI W2K3 - Log On Adv Settings
  14. If done correctly, the select device should have a Status of Connected instead of Inactive.

    Figure 12 - iSCSI W2K3 - Targets Connected
  15. For each device listed that has an Inactive status, follow the previous steps until each device
    has a "Connected" status.
  16. Once done, on the Targets tab, all of the iSCSI Bridge devices should have a Connected status.

    Figure 13 - iSCSI W2K3 - Targets Connected

    If not, go through the steps again to troubleshoot the issue, or consult the iSCSI Bridge User's Guide.

    If you have an Equallogic box, consult the following article:
    PowerVault TL2000 / TL4000 Tape Library - iSCSI Target Reconnecting in Microsoft™ Windows®
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.

Note:
For most purposes the Round Robin policy will provide the greatest performance increase.
Note:
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:
  1. 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.

    Figure 1 - iSCSI Initiator Targets Multiple Sessions

    Figure 2 - iSCSI Initiator Target Properties
  2. Click on the Connections button and a window should appear.

    Figure 3 - iSCSI Initiator Load Balance Policy
  3. To add a new connection to a session, click on the Add button and a new window should appear.

    Figure 4 - iSCSI Initiator Add Connection
  4. Now click on the Advanced button to see the Advanced Settings.

    Figure 5 - iSCSI Initiator Advanced Settings
  5. 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.

    Figure 6 - iSCSI Initiator Source IP
  6. While on this screen, CHAP can be setup; but, this is optional and not a requirement.
    When done, click on OK.
  7. 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.

    Figure 8 - iSCSI Initiator Session Properties Apply

    Figure 9 - iSCSI Initiator Target Properties
  8. 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,
    per device.
  9. 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.
