Overview
Overview
The HP-BRCM iSCSI boot feature allows a server to boot from a remote disk that supports Microsoft iSCSI Software Initiator (known as the iSCSI target) on a Storage Area Network (SAN) without having to directly attach a boot disk.
Booting from a remote disk on a SAN allows the boot process to be centralized and consolidates equipment resources. Unlike other implementations, iSCSI boot does not require a separate DHCP server or a PXE server.
Accelerated iSCSI Boot for Windows
HP Accelerated iSCSI capability can be used with HP NC-Series Broadcom iSCSI Boot Package for Windows. All accelerated iSCSI commands are handled by the adapter's HP iSCSI HBA driver. This feature is applied to all HP Multifunction Gigabit Ethernet Server Adapters at no additional cost for standup and mezzanine adapters; however, some embedded HP Multifunction Gigabit Ethernet Server Adapters require a ProLiant Accelerated iSCSI Pack license. For more information see the HP ProLiant Accelerated iSCSI for Windows User Guide.
Limitations
•A system crash may result if you bring down a network adapter that is iSCSI-boot enabled. The Windows Server 2003 SP2 operating system prevents you from disabling iSCSI-booted adapters.
•File system access lapses (due to unplugging the cable) for time critical "keep alive" processes (svchost) may cause reboots.
•Network adapter property changes (for example, Link Speed) can cause unrecoverable configuration changes, which may prevent booting.
•iSCSI target configuration changes (for example, Adapter Name) causes boot failure if you do not change the iSCSI boot configuration as well.
•Adapter failover during the software installation or the boot phase is not possible.
•Discovery protocols, such as Internet Storage Name Service, and Service Location Protocol are not supported during iSCSI boot installs.

Overview 5
Installation and configuration
Downloading the SoftPaq
1.Go to the HP website (http://www.hp.com/#Support).
2.Click Support & Drivers.
3.Select Download drivers and software (and firmware).
4.Type the adapter name in the For product box, and then click Go.
5.Select an operating system.
6.Click HP NC-Series Broadcom iSCSI Boot Package for Windows.
7.Click download and save the HP SoftPaq (sp#####.exe) file to a directory on your hard drive. The SoftPaq file is a self-extracting executable with a file name based on the SoftPaq number.
8.Click the SoftPaq file to extract the files.
Configure the server for iSCSI boot
Enable iSCSI boot and set the boot order
Before iSCSI boot can be used, you must first enable iSCSI boot on the adapter and then modify the boot order to select the iSCSI-enabled adapter as the boot device.
Enable iSCSI boot for HP network adapters
The iSCSI boot option ROM must be enabled before it can be used. Do not enable iSCSI boot on more than two adapters because option ROM space is limited and it may cause the iSCSI boot to fail.
The following sections describe how to enable iSCSI boot on embedded, mezzanine, and standup adapters.
Embedded adapters. The iSCSI boot option ROM is enabled on embedded adapters by using the RBSU tool that is built into the system ROM.
a.During the initial boot phase, press <F9> to enter the RBSU.
b.At the RBSU menu, select System Options.
c.At the System Options menu, select the embedded adapter.
d.Select Network boot (for G6 and later servers) or iSCSI boot. HP recommends that PXE be disabled on unused ports to conserve option ROM space.
e.Press <Esc> to exit the RBSU.
Mezzanine and Standup adapters. The iSCSI boot option ROM is enabled interactively at the console.
a.During the initial boot phase, press <Ctrl-S> when prompted to display the MBA Configuration Menu.
b.Verify that iSCSI is selected for the Boot Protocol entry.
Installation and configuration 6
c. Press <F4> to save the changes and then press <Esc> to exit the MBA configuration menu.
Set the boot order to boot from the iSCSI adapter
The iSCSI-enabled adapter must be listed first in the Standard Boot Order (IPL) list.
1.During the initial boot phase, press <F9> to enter the RBSU.
2.At the RBSU menu, select Standard Boot Order (IPL).
3.Verify that the iSCSI boot adapter is listed first in the IPL list. Modify the boot order, if necessary.
4.Press <Esc> to exit the RBSU.
Configure iSCSI parameters
The iSCSI boot software must acquire its iSCSI target parameters either statically (by disabling DHCP) or dynamically (by enabling DHCP). You can choose either of these methods.
Statically configure iSCSI parameters
In a static configuration, you must manually enter the system IP address, the system initiator IQN, and the target IQN using the iSCSI Configuration Utility.
1.Power on the server and when prompted select <Ctrl-S> to launch the MBA Configuration menu.
2.At the MBA Configuration menu enter the function key combination, such as <Ctrl-K> to enter the iSCSI Cfg menu. The key combination may vary. At the iSCSI Cfg menu, select General Parameters, and then select Disabled for the TCP/IP parameters via DHCP and the iSCSI parameters via DHCP parameters.
3.For the Boot to iSCSI target parameter, select Disabled if installing from a CD/DVD otherwise, select
Enabled.
4.For the Target as First HDD parameter, select Enabled.
5.For the Windows HBA Boot Mode parameter, select one of the following:
o Enabled for Windows Server 2003 or Windows Server 2008 if using the Offloaded iSCSI method of OS installation.
o Disabled for Windows Server 2008 Non-offloaded iSCSI method of OS installation.
6.Press <Esc> to exit the General Parameters Configuration Screen and then select Initiator Parameters.
7.At the iSCSI Initiator Parameters Configuration screen, enter values for the IP Address, Subnet Mask,
Default Gateway, Primary DNS, and Secondary DNS parameters as needed.
The iSCSI Name corresponds to the iSCSI initiator name to be used by the client system. If authentication is required then enter the CHAP ID and CHAP Secret parameters.
8.Press <Esc> to return to the Main Menu.
9.Select 1st Target Parameters and then enter values for the Target IP Address, Target name, and Login information. Press <Esc> to return to the Main Menu.
10.Select 2nd Target Parameters. This configuration screen allows a MPIO configuration to be established. The adapter attempts to connect to this iSCSI target as a backup session to be passed to the host operating system. The ISCSI driver components support MPIO as a standalone feature without the need of the MPIO components when Target 2 is present.
Enter values for the Target IP Address, Target name, and login information as needed.
Installation and configuration 7
11.Enter values for the Subnet Mask, Default Gateway, Primary DNS, and Secondary DNS parameters as needed. The iSCSI Name corresponds to the iSCSI initiator name to be used by the client system. If authentication is required, enter the CHAP ID and CHAP Secret parameters.
12.Press <Esc> to return to the Main Menu and then press <Esc> again to display the Exit Configuration screen and then select Exit and Save the Configurations.
Dynamically configure iSCSI parameters
In a dynamic configuration the IP address, initiator, and target information is provided by DHCP.
1.Power on the server, and press <Ctrl-S> to launch the MBA Configuration menu when prompted.
2.At the MBA Configuration menu, select the appropriate function key combination to enter the iSCSI Cfg menu. The key combination varies based on your configuration.
3.At the iSCSI Cfg menu, select General Parameters and then select Enabled for the iSCSI parameters via DHCP parameter.
4.For the Boot to iSCSI target parameter, select Disabled to install from a CD/DVD.
5.For the Target as First HDD parameter, select Enabled.
6.For the Windows HBA Boot Mode parameter, select Enabled.
7.Modify the iSCSI Name parameter based on the DHCP options that are used by the DHCP server.
oIf DHCP Option 17 is used, the initiator name is retrieved from the value entered in the Initiator Parameters screen. But if no value is entered, the controller defaults to the name: iqn.1995-05.com.broadcom.<11.22.33.44.55.66>.iscsiboot
where 11.22.33.44.55.66 is the controller MAC address.
oIf DHCP Option 43 is used, settings in the Inititator Parameters, 1st Target Parameters, or 2nd Target Parameters fields are ignored and do not need to be cleared.
8.Press <Esc> to exit and save the settings when prompted. Continue pressing <Esc> to exit the MBA Configuration Menu.
