Configuring iSCSI Virtual Drives

iSCSI virtual drives are used primarily to run supported operating systems that reside on an external server that function as the Sun Blade X3-2B host operating system.

iSCSI virtual drives must be configured in the iSCSI BIOS Setup Utility screens. You must set the iSCSI parameters on the selected port.

Before You Begin

• You should be familiar with iSCSI theory of operation for the selected OS.

• Refer to the OS documentation to verify that iSCSI targets can be mounted on a client.

• You will need access to an external iSCSI server running on any supported OS.

• The Sun Blade X3-2B must be in UEFI boot mode, not legacy boot mode. See Select UEFI or Legacy BIOS Boot Mode.

• You must provide the following information from the iSCSI target server. The following items are entered in to the Sun Blade X3-2B ISCSI BIOS Setup Utility screens:

  Item Example 1 Target name iqn.1988-12.com.oracle:x6270-m3-target 2 iSCSI initiator name iqn.1988-12.com.oracle:002222de444e Note - iSCSI requires iqn formats for its initiator and target names. 3 Virtual device Virtual Disk 0 4 Logical Unit Number LUN 0 Additional Information: 5 IP address of iSCSI server 111.111.1.11 (ivp4) 6 Port number 3210

Use this procedure to configure iSCSI virtual drives in the ISCSI BIOS Setup Utility.

1. Access the BIOS Setup Utility menus.

   See Access BIOS Setup Utility Menus.

2. In the BIOS Setup Utility menus, use the arrow keys to navigate to the UEFI Driver Control menu.

   ---

   Note - Ensure Legacy boot mode is not enabled.

   ---

   A list of all controllable devices appears.

   
   
3. To access the iSCSI screen, select iSCSI.
4. Enter the iSCSI Initiator name.
   1. Select iSCSI Initiator Name.

      The iSCSI Initiator Name dialog appears.

      
      
   2. Type the initiator name in iqn format, for example:

      iqn.1988-12.com.oracle:000000000000

5. To connect to the iSCSI drive, select the appropriate NIC port MAC address, for example:

   Port 00-11-22-DD-2E-AB.

   The port configuration screen appears.

   
   
6. Set the Enable iSCSI value to Enabled.

   Select Enable iSCSI, and then select Enabled or Disabled.

7. Set the Enable DHCP value to Enabled, if required.

   The Initiator IP address, Initiator Subnet Mask, and GateWay settings are removed.

   If you set DHCP to disabled:

   • Type the Initiator IP address.
   • Type the Initiator Subnet Mask.
   • Type the Gateway.

   ---

   Note - Use the same subnet.

   ---

8. Set Get target info via DHCP to Disabled, if required.
9. Set the Target Name.
   1. Select Target Name.

      The Target Name dialog appears.

      
      
   2. Type the iqn target name for example:

      iqn.1988-12.com.oracle:x6270-m3-target

10. Set the Target IP address.
    1. Select Target IP address.

       The Target IP address dialog appears.

    2. Type the target IP address of the iSCSI server in dotted-decimal notation, for example:

       111.111.1.11.

11. Set the Target port.
    1. Select Target port.
    2. Type the target port of the iSCSI server, , for example:

       3210.

       ---

       Note - When iSCSI is enabled on a network port, PXE is disabled for that port.

       ---

12. Set the Logical Unit Number.
    1. Select Boot LUN.

       The Boot LUN dialog appears.

    2. Type the hexadecimal representation of the logical unit number, , for example:

       0.

13. Set CHAP type to none, one way CHAP, or mutual CHAP.
14. Verify that your settings match the iSCSI target server information.
    
15. Save the changes and exit the BIOS Setup Utility.
16. Restart the server.
17. Press the F8 key (or Ctrl+P from a serial connection) when prompted while the BIOS is running the power-on self-test (POST) checkpoints.

    The Please Select Boot Device dialog box appears.

18. Verify that the iSCSI target entry appears in the boot list.
19. For instructions on installing an OS on an iSCSI drive, refer to the supported OS installation documentation.
