1. Create an iSCSI target.
2. Create a virtual disk.
3. Map the virtual disk to the iSCSI target created in step 1.
4. Associate an iSCSI initiator with the iSCSI target.
5. Record the iSCSI target name, TCP port number, iSCSI Logical Unit Number (LUN), initiator Internet Qualified Name
(IQN), and CHAP authentication details.
After configuring the iSCSI target, obtain the following:
• Target IQN
• Target IP address
• Target TCP port number
• Target LUN
• Initiator IQN
• CHAP ID and secret
Configuring the 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.
Boot to iSCSI target Controls whether the iSCSI boot host software attempts to boot from the iSCSI target
after successfully connecting to it. When the option is enabled, the iSCSI boot host
software immediately attempts to boot form the iSCSI target. If set to disabled, the
iSCSI boot host software does not attempt to boot from the iSCSI target and control
returns to the system BIOS so that the next boot device may be used. The One Time
Disabled option is used when you want to do a remote install of the OS to an iSCSI
target. As the option is named, it is set to disable on the first boot, then changes to
enabled on subsequent reboots to indicate that iSCSI boots from the iSCSI target.
