MBA Boot Protocol Configuration
To configure the boot protocol
1. Restart your system.
2. From the PXE banner, select CTRL+S. The MBA Configuration Menu appears (see Broadcom Boot Agent).
3. From the MBA Configuration Menu, use the UP ARROW or DOWN ARROW to move to the Boot Protocol option. Use
the LEFT ARROW or RIGHT ARROW to change the Boot Protocol option to iSCSI.
4. Select CTRL+K to access the iSCSI Configuration Utility.
NOTE: If iSCSI boot firmware is not programmed in the NetXtreme II network adapter, selecting CTRL+K will not
have any effect.
Static iSCSI Boot Configuration
In a static configuration, you must enter data for the system’s IP address, the system’s initiator IQN, and the target
parameters obtained in Configuring the iSCSI Target. For information on configuration options, see Table 1.
To configure the iSCSI boot parameters using static configuration
1. From the MBA Configuration Menu, select CTRL+K.
2. From the Main menu, select General Parameters.
3. From the General Parameters screen, set the following:
• TCP/IP parameters via DHCP: Disabled. (For IPv4.)
• IP Autoconfiguration: Disabled. (For IPv6, non-offload.)
• iSCSI parameters via DHCP: Disabled
• CHAP Authentication: Disabled
DHCP Vendor ID Controls how the iSCSI boot host software interprets the Vendor Class ID field used
during DHCP. If the Vendor Class ID field in the DHCP Offer packet matches the
value in the field, the iSCSI boot host software looks into the DHCP Option 43 fields
for the required iSCSI boot extensions. If DHCP is disabled, this value does not need
to be set.
Link Up Delay Time Controls how long the iSCSI boot host software waits, in seconds, after an Ethernet
link is established before sending any data over the network. The valid values are 0
to 255. As an example, a user may need to set a value for this option if a network
protocol, such as Spanning Tree, is enabled on the switch interface to the client
system.
Use TCP Timestamp Controls if the TCP Timestamp option is enabled or disabled.
Target as First HDD Allows specifying that the iSCSI target drive will appear as the first hard drive in the
system.
LUN Busy Retry Count Controls the number of connection retries the iSCSI Boot initiator will attempt if the
iSCSI target LUN is busy.
IP Version This option specific to IPv6. Toggles between the IPv4 or IPv6 protocol. All IP
settings will be lost when switching from one protocol version to another.
Windows HBA Boot Mode Set to disable when the host OS is configured for software initiator mode and to
enable for HBA mode. This option is available on NetXtreme II adapters.
