Configuring iSCSI Boot Parameters
Configure the Broadcom iSCSI boot software for either static or dynamic configuration. Refer to
Table 1
for configuration
options available from the General Parameters screen.
Table 1
lists parameters for both IPv4 and IPv6. Parameters specific to either IPv4 or IPv6 are noted.
NOTE: Availability of IPv6 iSCSI boot is platform/device dependent.
Table 1: Configuration Options
Option
Description
TCP/IP
parameters via
DHCP
This option is specific to IPv4. Controls whether the iSCSI boot host software acquires the IP address
information using DHCP (Enabled) or use a static IP configuration (Disabled).
IP
Autoconfiguration
This option is specific to IPv6. Controls whether the iSCSI boot host software will configure a stateless
link-local address and/or stateful address if DHCPv6 is present and used (Enabled). Router Solicit packets
are sent out up to three times with 4 second intervals in between each retry. Or use a static IP
configuration (Disabled).
iSCSI
parameters via
DHCP
Controls whether the iSCSI boot host software acquires its iSCSI target parameters using DHCP (Enabled)
or through a static configuration (Disabled). The static information is entered through the iSCSI Initiator
Parameters Configuration screen.
CHAP
Authentication
Controls whether the iSCSI boot host software uses CHAP authentication when connecting to the iSCSI
target. If CHAP Authentication is enabled, the CHAP ID and CHAP Secret are entered through the iSCSI
Initiator Parameters Configuration screen.
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.
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. (
Note
: This parameter cannot be changed when the
adapter is in Multi-Function mode.)
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
.
NOTE: For iSCSI boot-capable LOMs, the boot protocol is set via the BIOS. See your system documentation for
more information.
4. Select
iSCSI Boot Configuration
from
Main Menu
.
